RoHS lists a total of six hazardous substances, including: lead Pb, cadmium Cd, mercury Hg, hexavalent chromium Cr6+, polybrominated diphenyl ether PBDE, polybrominated biphenyl PBB.
The EU stipulates six hazardous substances, the highest of which are:
1 lead (Pb): 1000ppm;
2 mercury (Hg): 1000ppm
3 cadmium (Cd): 100ppm;
4 hexavalent chromium (Cr6+): 1000ppm;
5 polybrominated biphenyl (PBB): 1000ppm;
6 polybrominated diphenyl ether (PBDE): 1000ppm
ppm: solid concentration unit, 1ppm = 1 mg / kg
Homogeneous material: A material that cannot be subdivided by physical methods.
Lead: affects the central nervous system and the kidney system
Cadmium: Causes urinary pain due to kidney disease.
Mercury: affects the central nervous system and the kidney system
Hexavalent chromium: a genetic defect.
PBDE and PBB: Decomposes to produce carcinogenic dioxin, causing fetal malformations.
