Ranging in colour from yellow to deep-red maroon, cadmium pigments In certain areas, cadmium concentrations are elevated in shellfish and mushrooms (Jarup 2002). Cadmium Toxicity. Cadmium sulfide (CdS) can be utilized as a quantum dot that functions as a unique light-emitting semiconductor nanocrystal. The increased use in CdS has led to an increased inhalation and ingestion rate of CdS by humans which requires a broader appreciation for the acute and chronic toxicity of CdS. 1.4 Environmental fate Fertilizers produced from phosphate ores constitute a major source of diffuse cadmium pollution. Cadmium (Cd) is a nonessential heavy metal with potentially deleterious effects on different organisms. The council's report concluded that, while the toxicity of zinc cadmium sulfide itself was not well understood, the quantities of the chemical released by the Army would not have harmed the public even if the cadmium involved had acted just like purer, probably more toxic forms of the element.
