The Restriction of Hazardous Substances Directive 2002/95/EC (RoHS 1), short for Directive on the restriction of the use of certain hazardous substances in electrical and electronic equipment, was adopted in February 2003 by the European Union. [2] The initiative was to limit the amount of hazardous chemicals in electronics.
In the absence of LC 50 data on the poisonous (toxic) constituent substances, the mixture may be assigned a packing group and hazard zone based on simplified threshold toxicity tests. When these threshold tests are used, the most restrictive packing group and hazard zone must be determined and used for the transportation of the mixture.
The list is designated within the Controlled Substances Act [1] but can be modified by the U.S. Attorney General as illegal manufacturing practices change. Although the list is controlled by the Attorney General, the list is considered a DEA list because the DEA publishes and enforces the list.

If the amendment passes, China will have the same RoHS substances as the 2015 EU RoHS amendment. The expected publication date of the regulation is July 2022. The addition of phthalates to the RoHS regulation would advance China's green industrial development program, which is part of their 14th Five-Year Plan. [6]
Using potentially toxic substances in products other than those ingested by humans (such as electronic devices) may seem to be safe, but there are several ways in which chemicals can enter the human body and the environment. Substances can leave particles during consumer use, for example into the air where they can be inhaled or ingested. Even ...
RoHS seeks to limit the dangerous substances in circulation in electronics products, in particular toxins and heavy metals, which are subsequently released into the environment when such devices are recycled. The scope of RoHS 2 is widened to include products previously excluded, such as medical devices and industrial equipment.
Exposure to the coplanar stereoisomer 3,3',4,4',5,5'-hexabromobiphenyl (but not the non-coplanar stereoisomer) in genetically susceptible mice is known to cause immunotoxicity and disorders related to the central nervous system, and even at doses as low as 2.5 mg/kg, excess neonatal fatalities are observed (LD 50 is from 5–10 mg/kg).
