DOI: 10.1002/mbo3.70105
Abstract: 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. It was later… read more here.

DOI: 10.1016/j.atmosenv.2019.06.012
Abstract: Abstract Snow is an important reservoir of volatile and semi-volatile organic compounds. In this paper, the adsorption kinetics and thermodynamics of gamma-hexachlorocyclohexane (γ-HCH) and other two kinds of important pollutants in the environment, 1,4-Dichlorobenzene (p-DCB)… read more here.

DOI: 10.1016/j.chemosphere.2018.12.070
Abstract: Within this study different biochars (BC) with widely varying characteristics have been tested as materials for the adsorption of hexachlorocyclohexane's (HCH) isomers (α, β, γ and δ) from water. Three BCs produced from digestate (700 °C),… read more here.

DOI: 10.1016/j.chemosphere.2020.127212
Abstract: Organochlorine pesticides legacies, such as hexachlorocyclohexane (HCH) and dichlorodiphenyltrichloroethane (DDT), remained in sediments or soils due to their difficulty in decomposition, especially in the agricultural areas where pesticides were widely used historically. Different from the… read more here.

DOI: 10.1016/j.ecoenv.2019.02.089
Abstract: As endocrine disrupting chemicals, hexachlorocyclohexane (HCH) isomers were reported to impair the intrauterine growth. Although the findings of HCHs with preterm birth were well established, the associations with gestational age were limited. In the present… read more here.
