Evaluation of the phytotoxicity of decabromodiphenyl ether (BDE-209) in Chinese cabbage

open access: yesBiologia Plantarum, 2022
Decabromodiphenyl ether (BDE-209), a major component of brominated flame retardants, has been detected in considerable amounts in the soil. Given that BDE-209 is toxic, ubiquitous, and persistent, it may cause toxic effects on vegetables planted in ...
