Insights on Anabaena sp. PCC 7120 Responses to HCH Isomers: Tolerance, Degradation, and Dynamics on Potential lin Genes Expression [PDF]

open access: yesMicrobiologyOpen
Hexachlorocyclohexane (HCH) was extensively used as a pesticide until the 1990s. It was synthesized by benzene photochlorination, resulting in a mixture of stereoisomers, which included α‐, β‐, γ‐, and δ‐HCH, among others.

Modeling historical budget for β-Hexachlorocyclohexane (HCH) in the Arctic Ocean: A contrast to α-HCH

open access: yesEnvironmental Science and Ecotechnology, 2023
The historical annual loading to, removal from, and cumulative burden in the Arctic Ocean for β-hexachlorocyclohexane (β-HCH), an isomer comprising 5–12% of technical HCH, is investigated using a mass balance box model from 1945 to 2020.
