Why did the Electronics Industry Develop Rohs Standards
It was first noticed that electrical and electronic equipment contains heavy metals that are harmful to human health. In 2000, cadmium was found in a batch of marketed game console cables. After that, the EU implemented the Rohs stadard on July 1, 2006. At that time, electrical and electronic prodcuts that use or contain heavy metals will not be allowed to enter the EU market.
The six types of harmful elements recognized by the world as the greatest threat to human health in electronic products are Pb, Cd, Hg, Cr6+, PBDE, PBB. Traditional mainstream electronic products will use these types of toxic substances in large quantities. They are harming our bodies without knowing it. In the production of electrical and electronic products, the solders and printing inks used in packing boxes all contain harmful heavy metals such as lead .
Usually, the victims are workers who process electronic products in developing countries.
But in the process of normal use, or in the case of damage, these toxic substances may also leak out. For example, broken monitors or LCD TVs may cause mercury leakage.
In additionl the disposal of waste electronic products will generate organic pollutants with carcinogenic, mutation and teratogenic effects, such as lead, mercury, cadmium and other heavy metals, which have a very toxic effect on human organs. Do not forget that electronic products have penetrated tens of millions of homes and copanies and countries.
The RHOS standard is to prevent the incorporation and use of prohibited substances, planned abolished substances, and reduced substances(hazardous substances) in environmental management substances contained in components and materials in electrical and electronic equipment. Protecting the earth’s environment and human health and maintaining the sustainable and healthy development of society are missions that no one can ignore.
