　　Toxic substances in silicone, heavy metal ROHS tester, Tianrui Instrument

1. Lead (Pb): Lead is a toxic heavy metal widely used in circuit boards and solder. The toxicity of lead can have serious effects on the nervous system, blood system, and kidneys, especially in children. The RoHS directive stipulates that the lead content shall not exceed 0.1% (1000 ppm). Reducing the use of lead can effectively reduce environmental pollution and health risks.

2. Mercury (Hg): Mercury is a highly toxic metal commonly used in switches and relays. Mercury and its compounds can enter the food chain through biological accumulation, causing serious damage to the human nervous system, digestive system, and immune system. The RoHS directive stipulates that the mercury content shall not exceed 0.1% (1000 ppm). The control of mercury can significantly reduce its harm to ecosystems and human health.

3. Cadmium (Cd): Cadmium is a toxic heavy metal commonly used in batteries, electroplating, and pigments. Cadmium can cause serious damage to the kidneys, bones, and respiratory system, and is carcinogenic. The RoHS directive stipulates that the cadmium content shall not exceed 0.01% (100 ppm). Strictly controlling the use of cadmium can prevent soil and water pollution, protect the ecological environment and public health.

4. Hexavalent chromium (Cr6+): Hexavalent chromium is mainly used for metal coatings and has anti-corrosion properties. Hexavalent chromium has strong carcinogenicity and can cause serious harm to the skin, respiratory system, and internal organs. The RoHS directive stipulates that the hexavalent chromium content shall not exceed 0.1% (1000 ppm). Reducing the use of hexavalent chromium can lower the pollutant content in industrial wastewater and exhaust gas, protecting the occupational health and public health of workers.

5. Polybrominated biphenyls (PBBs): PBBs are flame retardants, commonly used in plastics, foam and textiles. Polybrominated biphenyls have persistence and bioaccumulation, posing potential hazards to the environment and human health. The RoHS directive stipulates that the content of polybrominated biphenyls shall not exceed 0.1% (1000 ppm). By restricting the use of polybrominated biphenyls, their accumulation in the environment can be reduced and the toxicity risk in the food chain can be lowered.

6. Polybrominated diphenyl ether (PBDE): PBDE is a common flame retardant widely used in plastic casings and cables of electronic products. Polybrominated diphenyl ethers can enter the human body through air, dust, and food, affecting thyroid hormones and the nervous system. The RoHS directive stipulates that the content of polybrominated diphenyl ethers shall not exceed 0.1% (1000 ppm). Restricting the use of polybrominated diphenyl ethers can help reduce their harm to the environment and human health.

7. Di (2-ethylhexyl) phthalate (DEHP): DEHP is a plasticizer commonly used to soften plastic products such as cables and flooring. DEHP has endocrine disrupting properties and can have adverse effects on the reproductive system and development. The RoHS directive stipulates that the DEHP content shall not exceed 0.1% (1000 ppm). Reducing the use of DEHP can lower its potential risks to the health of children and adults.

8. Phenylbutyl phthalate (BBP): BBP is also a plasticizer widely used in PVC plastic products. BBP has endocrine disrupting and reproductive toxicity, which can have negative effects on fertility and fetal development. The RoHS directive stipulates that the BBP content shall not exceed 0.1% (1000 ppm). Controlling the use of BBP can help protect human reproductive health and child development.

9. Dibutyl phthalate (DBP): DBP is commonly used as a plasticizer in adhesives, sealants, and textile coatings. DBP has endocrine disrupting properties and can affect the reproductive system and developmental processes. The RoHS directive stipulates that the DBP content shall not exceed 0.1% (1000 ppm). By restricting the use of DBP, its harm to the environment and health can be reduced.

10. Diisobutyl phthalate (DIBP): DIBP is another common plasticizer mainly used in plastic products and coatings. DIBP has potential toxicity to the reproductive system and development. The RoHS directive stipulates that the DIBP content shall not exceed 0.1% (1000 ppm). Controlling the use of DIBP can help reduce its impact on human health and the environment.
