Cadmium - Chemical Safety Facts
2022年10月14日 · Cadmium helps created bright, long-lasting pigments used in paints and coatings and to give tint to plastics and ceramics. Some PVC in building and construction and electronics uses cadmium stabilizers. Cadmium also helps makes batteries used to power cell phones, laptops and other electronics.
Cadmium pigments in consumer products and their health risks
2019年3月20日 · In this paper, the uses of cadmium and its compounds in products amenable to the consumer are reviewed, with the focus on the occurrence of cadmium-based sulphide and sulphoselenide pigments used to colour plastics, paints and ceramics, and where the metal is likely to appear in a wide range of products where it is not necessarily expected or ...
Cadmium - Wikipedia
Cadmium is a chemical element; it has symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 ...
The Effects of Cadmium Toxicity - PMC - PubMed Central (PMC)
Cadmium (Cd) is a toxic non-essential transition metal that poses a health risk for both humans and animals. It is naturally occurring in the environment as a pollutant that is derived from agricultural and industrial sources.
Cadmium pigments in consumer products and their health risks
2019年3月20日 · Cadmium is encountered across a wide range of contemporary plastic products, mainly because of the unregulated recycling of electronic waste and polyvinyl chloride. However, concentrations are generally low (<100 μg g -1), conforming with current limits and posing minimal risk to consumers.
Hazardous metal additives in plastics and their environmental …
2021年11月1日 · Historically, many additives and catalysts used in plastics were based on compounds of toxic metals (and metalloids), like arsenic, cadmium, chromium (VI), and lead. Despite subsequent restrictions, hazardous additives remain in plastics in societal circulation because of the pervasiveness of many products and the more general contamination of ...
the identification of uses of cadmium compounds in plastic materials and the technical and economical feasibility of alternatives as well as risk assessment of cadmium and its compounds in plastic materials as well as their alternatives.
Color: An Important but Overlooked Factor for Plastic Photoaging …
2022年6月21日 · For example, sunlight can regulate the release of cadmium from the aqueous phase of cadmium-containing colored microplastics. (5) Furthermore, the color of microplastics may potentially affect their ingestion by aquatic organisms because some organisms, such as gobies, are visual predators and are prone to ingest microplastics with colors ...
The multi-analytical in situ analysis of cadmium-based pigments …
2020年9月1日 · Optical microscopy (OM) was used to assess the distribution of cadmium pigments in the plastic samples. Images were acquired in bright-field and dark-field illumination using a Zeiss Axioplan 2 Imaging system (HAL 100) coupled to a …
The Agency has investigated the use of cadmium and its compounds in plastic materials. Based on the information received so far, the remaining uses seem to be those that fall under the scope of the derogation in paragraph 3, i.e. plastic articles coloured with mixtures containing cadmium for safety reasons.
