Applications covered include targeted drug delivery, water purification and hydrogen generation. This is an important research resource for those wishing to learn more about how eco-efficient nanoparticles can best be used. Numerous applications are based on their unique luminescent properties, which are highlighted in this volume. exists as cadmium sulfide, is refined during zinc production, and; occurs in association with zinc. Klimisch (1993) studied the lung deposition, lung clearance, and renal accumulation of inhaled CdS in rats. The leaching residue of the lead-zinc sulfide tailing (LRT) is the only residue generated from the tailing leaching recovery process; it is a typical hazardous material for its high heavy-metal contents and high acidity. Suggested Citation:"Toxicity and Related Data on Zinc Cadmium Sulfide." National Research Council. Chemical Formula: ZnS | CAS No. However, CdO is soluble in vivo whereas ZnCdS is insoluble in vivo; therefore, the results of Baranski (1985) cannot be extrapolated to inhala-, tion exposures involving ZnCdS. For example, cadmium yellow consists. The bioavailability of a compound relies heavily, if not exclusively, on its physical and chemical properties, particularly its solubility. It is an herbicide typically used for moss control. lead to nausea, metallic taste, stomach ache, vomiting, and bloody diarrhea. Zinc is an essential mineral for human, animal, and
Those studies suggest that the ambient concentrations of CdO, a compound soluble in vivo, might cause developmental toxicity in humans. Solubility makes zinc available to plants
(In vivo solubility is the ability of a material to leave the site of administration and be distributed systemically to other parts of the body.) The concentration of copper or silver was about 0.005%. Favino and others (1968) did not detect changes in androgen function in 10 workers in a cadmium-alkaline battery plant even though measurable amounts of urinary cadmium were detected and workers had experienced ulceration of the nasal mucosa and anosmia. Primary hazard is to the environment. % and 18 wt. Animal experiments do not show that inhaled or ingested cadmium induced prostatic cancer. Zinc is a nutrient that plays many vital roles in your body. As a biologically active gaseous mole-cule, hydrogen sulfide (H2S) regulates plant growth and development. Aims Zinc (Zn) is a toxic element for plant at high concentrations. Short- and long-term batch experiments were conducted to explore ZnO and Cu 0 NPs toxicity to acetoclastic methanogens in sulfate-containing (0.4mM) and sulfate . The sulfide addition consistently ameliorated the high toxicity of free metal cations by the formation of dissolved metal-sulfide complexes as well as solid precipitates. Zinc binds to proteins or organic acids in plants. The absorption factor for inhaled CdS based on the data of Rusch and others (1986) was 0.070.1%. It has been proposed that acid volatile sulfide (AVS) is an important sediment phase for determining the toxicity of certain trace metals. Due to the large output of LRT, and because its main components are Ca, Si, and Al, the preparation of building construction materials with LRT was studied. There are very few reported studies on the toxicity of cadmium compounds that are poorly soluble in vivo, such as. Of 1,502 patients tested, only 25 showed a positive reaction that was interpreted as reflecting acute skin irritation rather than contact allergy to cadmium (Wahlberg 1977). A yellowish-white powder in a liquid. Monday - Friday, between 8:00am - 12:00pm Pacific Time (11:00am - 3:00pm Eastern Time) at 1-800-858-7378 or visit us on the web at
This two-volume compendium focuses on reactivity risks of chemicals, alone and in combination; toxicity hazards are only included for unexpected reactions giving volatile poisons Predict, avoid, and control reactivity danger with this ... The main differences are that it takes considerably higher CdS concentrations to produce lung lesions and that substantially less cadmium becomes bioavailable from inhaled or ingested CdS than from the more-soluble cadmium compounds. These ores are concentrated by selective flotation, yielding zinc concentrates containing 50-60 percent zinc, as well as lead, copper, and sometimes pyrite concentrates. Thus, this approach will overestimate the risk. Traces of lead and other impurities may be present in pigment powders. It can be found in animals, plants,
Epidemiologic studies show some increase in lung cancer among workers in 5 of 6 occupationally exposed populations in Europe and the United States (IARC 1993). Japanese men who ingested cadmium-contaminated rice during World War II experienced higher mortality from prostatic cancer (standardized mortality ratio, 1.66) and a higher incidence of prostatic hyperplasia in one polluted area but not in another (Shigematsu and others 1982). Currently there are
Zinc salts are slightly toxic or practically non-toxic to birds and highly toxic to freshwater fish and
Experimental studies of animals have not consistently shown other types of cancer after cadmium inhalation or ingestion (IARC 1993). Leukemia can be produced by cadmium ingestion in zinc-deficient rats; it can be prevented by simultaneous zinc supplementation (IARC 1993). Control measures include: (1) enclosing chemical processes for severely following all label instructions carefully. Upon learning of the tests, many citizens and some public health officials in the affected cities raised concerns about the health consequences of the tests. Numerous rodent studies have shown that oral exposure to soluble cadmium can reduce fetal or pup weights and cause skeletal malformations (ATSDR 1993). Bees and other pollinators are not likely to be harmed because they do not
Zinc is not inherently a toxic element. Chromosomal aberrations have been found in most studies that involved cadmium treatment of mammalian cells (Deaven and Campbell 1980; Rohr and Bauchinger 1976) and in some studies that used human lymphocytes in culture (Gasiorek and Bauchinger 1981; Shiraishi and others 1972) and bone marrow cells after intraperitoneal (Mukherjee and others 1988a) and oral (Mukherjee and others 1988b) exposure of mice. : AC370080000; AC370080250; AC370081000 CAS-No 557-34-6 Synonyms Acetic acid, zinc salt. Zinc sulfide, when combined with slight impurites, has phospherescent properties. crease in the incidence of lung tumors (OSHA 1992; Pott and others 1987). The sulfate and chloride salts of cadmium have very high solubilities in water (Weast 1985): cadmium chloride, CdCl2, has a reported solubility limit of 1,680,000 mg/L at 20°C and cadmium sulfate, CdSO4, a reported solubility limit of 608,000 mg/L at 20°C. Washington, DC: The National Academies Press. used for moss control. This document is
This study evaluated the role of biogenic sulfide in attenuating ZnO and Cu(0) NP toxicity to methanogens. Hence, here the toxicity of heavy metal free ZnSe/ZnS QDs on two scenarios were assessed, (i) HEK cells as in vitro system and (ii) Swiss Albino mice as in vivo model. Specifically, zinc chloride, zinc oxide, zinc sulfate, and zinc sulfide will be discussed. Zinc phosphide has been used widely as a rodenticide. U.S. EPA. For better coatings and plastics . Evidence supporting the theory with respect to chronic exposures is lacking. ZINC SULFATE Page 3 of 6 Workplace Controls and Practices Very toxic chemicals, or those that are reproductive hazards or sensitizers, require expert advice on control measures if a less toxic chemical cannot be substituted. Faced with the task of evaluating the potential toxicity of ZnCdS, a substance with largely unknown toxic potential but reasonably well-known physical and chemical properties, the subcommittee considered it to be prudent to examine the toxicity and related data on the most-toxic element in ZnCdS, cadmium. A study on the toxicokinetics of inhaled CdS (Oberdörster 1990; Oberdörster and Cox 1990) provides evidence that inhaled CdS is not absorbed from the lungs into systemic circulation. Show this book's table of contents, where you can jump to any chapter by name. History. This book assesses the public health effects of the Army's tests, including the toxicity of ZnCdS, the toxicity of surrogate cadmium compounds, the environmental fate of ZnCdS, the extent of public exposures from the dispersion tests, and ... Cadmium lemon. The toxicity of zinc sulfate depends on the amount
After exposures of female pregnant rats to CdO at 0.16 mg/m3, decreases in weight gain, osteogenesis, and viability were also observed in offspring. Phosphine is a very toxic gas. zinc can cause vomiting, diarrhea, lack of appetite, depression, yellow coloration of
Factors contributing to the severity of cadmium toxicity to bone include renal disease, dietary deficiencies (particularly low dietary calcium), vitamin D deficiency, and low estrogen concentrations. 1.800.858.7378 npic@ace.orst.edu http://npic.orst.edu. Zinc compounds have variable toxicity, but generally are of low toxicity. Such important end points as fertility and reproductive function were not studied. Found inside – Page iChapters 4-19 provide the subcommittee's review and assessment of health risks posed by exposure to each of the 16 FR chemicals. Data gaps and research needs are provided at the end of these chapters. With an emphasis on passive sampling, this volume focuses on the environmental monitoring for common gaseous pollutants. You can limit your exposure to zinc sulfate by
Methods: QD were composed of a cadmium-selenide (CdSe) core (~5nm) with a zinc sulfide (ZnS) shell functionalized with carboxyl (QD-COOH) or amine (QD-NH2) terminal groups. Aims Zinc (Zn) is a toxic element for plant at high concentrations. Only a few end points were evaluated in those studies including menstrual cycling and serum hormone concentrations. Zinc cadmium sulfide, created by heating a mixture of the compounds zinc sulfide and cadmium sulfide, was reportedly chosen by the Army for the physical similarities its powder form shares with a . NPIC provides Found insideThis new edition emphasizes the relationship between rocks and minerals, right from the structures created during rock formation through the economics of mineral deposits. Do you want to take a quick tour of the OpenBook's features? Zinc metal is not found freely in nature; rather it occurs in the +2 oxidation state primarily as various minerals such as sphalerite (zinc sulfide), smithsonite (zinc carbonate), and zincite (zinc oxide). It plays a role in how your page is seen by search engine crawlers, and how it appears in SERPs a Death rates in cadmium workers compared with men in Colorado, followup to 1984. You can be exposed if you are applying zinc sulfate and you get it
An exposure to cadmium that produces a kidney concentration of 200 µg/g wet weight is considered a threshold for renal dysfunction in an adult population chronically exposed to cadmium (Friberg and others 1974; Kjellström and others 1977, 1984; Roels and others 1983). Although some foods contain zinc well above the UL of 40 mg per day . Common zinc compounds found at hazardous waste sites include zinc chloride, zinc oxide, zinc sulfate, and zinc sulfide. In three cohorts (Thun and others 1990; Sorahan 1987; Kazantzis and others 1988), the standardized mortality ratio (SMR) for lung cancer increases with either length of employment or cumulative exposure to cadmium. Found insideAs the technology of this interdisciplinary science has diversified over the last five years, this book provides a valuable source for scientists and students in a number of disciplines, including geology, chemistry, metallurgy, ... Aims Zinc (Zn) is a toxic element for plant at high concentrations. Cadmium does not appear to cause germ-cell mutations or chromosomal damage after oral (Sutou and others 1980; Zenic and others 1982) or intraperitoneal (Epstein and others 1972; Mailhes and others 1988) exposure in animals, but does so after subcutaneous exposure (Watanabe and Endo 1982; Watanabe and others 1979). Zinc (Zn) is an essential micronutrient for plant life. FACED WITH THE TASK of evaluating the potential toxicity of zinc cadmium sulfide (ZnCdS), a compound with largely unknown toxic potential but reasonably well-known physical and chemical properties, the subcommittee considered it to be prudent to examine toxicity and related data on the most-toxic element in ZnCdS, cadmium. Chisolm and Handorf (1985, 1987) have also postulated that cadmium exposure can play a role in pregnancy-induced hypertension and suggested that animals late in gestation might be uniquely sensitive to this effect. U.S. Environmental Protection Agency (U.S. EPA). the fact sheet on Pets and Pesticide Use for more information. solubility is a major factor in determining the carcinogenicity of cadmium compounds. If any exposures occur, be sure to follow the First
They have a wide range of water solubility, from 1.3 mg/L for CdS to 1,680,000 mg/L for CdCl2 (see Table 4-1). The ZnCdS used in the Army studies was composed of about 80% zinc sulfide (ZnS) and 20% cadmium sulfide (CDs). doi: 10.17226/5739. No acute-inhalation studies of cadmium toxicity to the kidney were listed; acute oral exposures to CdCl2 as high as 150 mg/kg for 1 d in rats were reported to have no renal effect (Kotsonis and Klaassen 1977). washing your hands first. Soluble ions released by zinc oxide (ZnO) and copper (Cu(0)) nanoparticles (NPs) have been associated with toxicity to methanogens. between Oregon State Acid‐volatile sulfide (AVS) has been proposed as the primary normalization phase for the development of sediment quality criteria for certain cationic metals. (IPCS 1992). The result is a soft white pigment that is widely used by both coating formulators and . Thus, for 2 h, an exposure at 450 µg/m3 (900. µg-hr/m3) was a NOAEL in the studies by Grose and others (1987), and exposure for 3 h at 440 µg/m3 (1,320 µg-hr/m3) was a LOAEL in the Buckley and Bassett study (1987). Therefore, one can infer from this study that the ambient concentrations of CdO might cause developmental toxicity in humans. DEVELOPMENTALANDREPRODUCTIVESYSTEM—ATSDR has published a toxicological profile on cadmium (ATSDR 1993) that includes an excellent review of the reproductive and developmental toxicity of cadmium. In experimental animals, inhalation of soluble cadmium compounds has been shown to produce acute lung injury (chemical pneumonitis) and chronic lung injury (fibrosis and emphysema). DESCRIPTION: A liquid antiseborrheic, antifungal preparation for topical application. internal environment to keep zinc levels steady. The aim of this study is to reveal the ameliorative effects of H2S on the physiological and molecular responses of a hyperaccumulator to Zn toxicity. CdS can produce lung tumors in rats. The Army has long maintained that zinc cadmium sulfide is an inert substance, harmless to humans in the concentrations sprayed in the air in Minneapolis, St. Louis, and the other test sites. Found insideThis book aims to provide the reader with a comprehensive overview of the current state of the art in nanotoxicology, featuring the most important developments and critical issues regarding the use of and exposure to nanoparticles. ATSDR (1993) has compiled a list of animal studies whose results yield NOAELs for renal effects of cadmium exposure. Zinc is obtained from complex ores containing 1-4 percent zinc in the form of a sulfide, as well as Cu, Pb, Ag, Au, Cd, and Bi. This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments. The toxicity of zinc, its interaction with cadmium, and the toxicity of . ATSDR has set a chronic inhalation minimal-risk level (defined as an estimate of the highest daily human exposure to a chemical at a dose that is likely to be without appreciable risk of adverse noncancer effects over a specified duration of exposure) for cadmium-induced renal toxicity of 0.2 µg/m3 (ATSDR 1993). pesticide-related topics to enable people to make informed For better coatings and plastics . What are some products that contain zinc sulfate? Uses advised against Food, drug, pesticide or biocidal product use. products in the United States since 1973. our disclaimer | Contact us | About NPIC | En español. The resulting precipitation of CdS in reducing environments can control the effective solubility of cadmium in natural waters. Zinc has many commercial uses as coatings to prevent rust, in dry cell batteries, and mixed with other metals to make alloys like brass, and bronze. When such compounds are absorbed, the most-sensitive sites for injury are the lungs, kidneys, and bones; studies have also been conducted on the effects of soluble cadmium compounds on the immune system and the reproductive and developmental system. Found insideRice is a staple crop in many coastal and non-coastal areas of the globe and requires a large production area. With the increasing trends in population , it is pivotal to increase the production of this important crop for sustainability. ZnS is also used as a detector of alpha-rays, which render it luminescent. and other organisms in soil; that availability depends on soil pH. Reports suggest that the presence of toxic elements at the QD core (e.g., cadmium, selenium) is responsible for its toxicity in in vivo and in vitro levels. Not a MyNAP member yet?

The toxicity of zinc, its interaction with cadmium, and the toxicity of copper and silver are discussed in Appendix D. This chapter reviews the physical and chemical properties, toxicokinetics, and toxicity of cadmium and cadmium compounds. View our suggested citation for this chapter. FACED WITH THE TASK of evaluating the potential toxicity of zinc cadmium sulfide (ZnCdS), a compound with largely unknown toxic potential but reasonably well-known physical and chemical properties, the subcommittee considered it to be prudent to examine toxicity and related data on the most-toxic element in ZnCdS, cadmium. A study of French women occupationally exposed to heavy metals showed doubled concentrations of cadmium in the hair of mothers and newborns relative to matched controls (1.45 versus 0.59 ppm in exposed mother's hair and 1.27 versus 0.53 ppm in transplacentally exposed newborn hair) but did not show any adverse effects in the newborns (Huel and others 1984). On the basis of a review of the physical and chemical properties, toxicokinetics, and the toxicity of cadmium compounds, the subcommittee reached the following conclusions: Bioavailability of cadmium is a key determinant of the toxicity of a cadmium compound. These data are summarized below. One study in rats resulted in
Cadmium exposures associated with increased lung-cancer risk in human and animal studies were to much higher concentrations for longer periods and involved more biologically soluble compounds than the exposures to cadmium from ZnCdS in the Army's testing program. University. Rats exposed to 10 weekly intratracheal instillations of 250 µg of CdS had a statistically significant in-. contact can damage the skin leading to ulcers, blisters and scarring. Studies on the carcinogenicity of cadmium and cadmium compounds were reviewed most recently by the International Agency for Research on Cancer (IARC) in 1993. Zinc cadmium sulfide was a suitable tracer, because it fluoresces under ultraviolet (UV) light and single particles could be counted on samplers around the country. system, and the pancreas. - Chitosan and Its Derivatives for Drug Delivery Perspective, by T. A. Sonia and C. P. Sharma.- Chitosan-based Nanoparticles in Cancer Therapy, by V.-K. Lakshmanan, K. S. Snima, J. D. Bumgardner, S. V. Nair, and R. Jayakumar. NPIC is a cooperative agreement making decisions about pesticide use. Cadmium compounds differ in their toxicity: compounds that are insoluble in vivo are less toxic than soluble ones. children may be especially sensitive to pesticides, Oregon State This study examines the role of AVS in predicting the toxicity of zinc, lead, and . Please read For more detailed information about zinc sulfate please visit the list of referenced resources or call the National Pesticide Information Center,
A NOAEL cannot be determined until a definite immune pattern is characterized for this chemical. The study's hypothesis was that placental cadmium accumulation was associated with decreased birthweight. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. Zinc in the
Early studies of occupational exposure suggested increased deaths from prostatic cancer, but the association weakened with continued followup and has not shown a clear dose-response trend (IARC 1993). (See discussion earlier in this chapter about the solubility of cadmium compounds and implications for noncancer end points.). REPRODUCTIVETOXICITY—Early studies of the effect of cadmium exposure on human male fertility did not find adverse effects on fertility (Kazantzis and others 1963) or on urinary androgen excretion (Favino and others 1968). LUNG—In humans, high concentrations of CdO fumes or dusts (milligrams per cubic meter) are irritating to the respiratory tract; irritation does not occur following lower inhalation exposures. on your skin, breathe it in, or accidentally eat a product. zinc sulfate resulted in changes of the blood chemistry. Immediate steps should be taken to limit spread to the environment. To the best of our knowledge the chemical, physical and toxicological properties of zinc sulfide have not been thoroughly investigated and recorded. Breathing
In Minnesota, while some soils are capable of supplying adequate amounts for crop production, addition of zinc fertilizers is needed for others. Traces of lead and other impurities may be present in pigment powders. Zinc combines with other elements to form zinc compounds. Zinc sulfate is a combination of sulfur and zinc. In the presence of sulfide ions and under reducing conditions, CdS is formed over a wide pH range.

Oberdörster (1990) estimated that 90% of the remaining inhaled CdS was removed slowly from the lung into the gastrointestinal tract by normal mechanical clearance processes. Zinc is also an essential nutrient for animals. Both maternal and fetal weight changes were noted after exposure to CdCl2 for 21 d at 0.6 mg/m3 (Prigge 1978). The mortality experience of these populations has been studied repeatedly (Elinder and others, 1985); Tables 4-2 and 4-3 present. that there is not enough information to determine whether or not zinc sulfate can cause cancer in humans. Two of the plants (groups 1 and 2) are metallurgic facilities, two (groups 4 and 5) are nickel-cadmium battery manufacturers, and one (group 3) is a compendium of 17 plants in the U.K., including a large zinc smelter. Toxicologic Assessment of the Army's Zinc Cadmium Sulfide Dispersion Tests. Deciding whether or not to control is still a good question to consider. Insoluble in water and denser than water. Women were believed to have been exposed to lead and cadmium dust from the smelter. Selenium sulfide is an antifungal agent often used in shampoos for the treatment of dandruff and seborrheic dermatitis. Zinc sulfide (ZnS) and aluminum doped zinc sulfide (ZnS:Al) thin films have been prepared by chemical bath deposition onto glass substrates at 85 °C using non-toxic complexing agents by varying the Al concentration between 0 wt. The subcommittee reviewed the toxicity of in vivo soluble and insoluble cadmium compounds. Clinical symptoms are circulatory collapse, hypotension, shock . It said it was sprayed 61 times in four parts of Minneapolis, from generators in the rear . Studies that compared the potential inflammatory response to intra-tracheal instillation of 30 µg of different cadmium compounds in rats (CdCl2, CdO, and CdS) reported that CdS failed to elicit any substantial influx of neutrophils, lavagable protein and enzyme activities in bronchoalveolar lavage fluid 24 h after exposure, whereas the other cadmium compounds tested resulted in substantial changes in these characteristics (Oberdörster and others 1985). The committee estimated that an average-size male could inhale as much as 500 micrograms of cadmium sulfide over a few days without causing toxicity in the lungs. Later studies by König and others (1992) indicated that 50-63% of CdS used in the inhalation studies of Oldiges and others (1989) might have been converted to the more-soluble CdSO4, which is known to be a pulmonary carcinogen in rats. Cadmium has been shown to concentrate in testicular tissue after occupational exposure (Smith and others 1960). SAFETY DATA SHEET Creation Date 26-Sep-2009 Revision Date 11-Apr-2019 Revision Number 4 1. DERMALTOXICITY—A search of the available reports on the toxicity of cadmium and its compounds failed to identify any studies in which skin exposures have produced serious adverse health effects in humans (ATSDR 1993). studies are conducted and reported, cadmium may be considered to be a potential mutagenic agent. Comprehensive reviews of the various investigations have been provided by Occupational Safety and Health Administration (OSHA 1992) and the Agency of Toxic Substances and Disease Registry (ATSDR). History. The only oxidation state of importance for cadmium under environmental conditions is +2. The high prevalence of cadmium-induced kidney toxicity (30-80%) in both areas indicated systemic circulation of cadmium (IPCS 1992). This section reviews the genotoxicity of soluble and insoluble cadmium compounds. The main focus of the subcommittee's review was to evaluate the toxicity associated with acute inhalation exposures to cadmium, because the exposures from the use of ZnCdS as a tracer particle were brief and sporadic.
