recommendations! Published in 2021 at "Environmental Science and Pollution Research"

DOI: 10.1007/s11356-021-13549-7

Abstract: Chromite ore processing residues (COPR) are real environmental threats, leading to CrO42-, i.e., Cr (VI) leaching into groundwater. It is of serious concern as Cr (VI) is proven to be carcinogenic. Here we emphasize the… read more here.

DOI: 10.1016/j.chemosphere.2018.09.004

Abstract: Polybrominated diphenyl ethers (PBDEs) belong to a class of persistent organic pollutants (POPs), with potential toxicity to the liver, reproductive system, and development of mammals. The highly toxic and concentrated congener, 2,2',4,4'-tetrabromodiphenyl ether (BDE-47), was… read more here.
