Self-purification of Aquatic Media from Hexachlorocyclohexane in a Radical Process

Chemistry Journal of Moldova: General, Industrial and Ecological Chemistry, 2019
It is known, that highly toxic pesticide hexachlorocyclohexane (HCH) is resistant to decomposition and has a long-term accumulating capacity. Nevertheless, it undergoes complete degradation in reactions with hydroxyl radicals in Fenton-like systems.

Degradación de isómeros del hexaclorociclohexano (HCH) por Anabaena PCC7120 [PDF]

, 2018
El hexaclorociclohexano (HCH) fue ampliamente utilizado como pesticida entre 1930 y 1990 e inicialmente se aplicó como una mezcla técnica que contenía α-HCH (60-70%), β-HCH (5-12%), γ-HCH (10-15%) y δ-HCH (6-10%).

Lindane degradation potential of methanotrophs and soil microbial biomass from HCH contaminated sites

Environmental Advances
In the present study, soil physico-chemical properties, hexachlorocyclohexane (HCH) isomers, lindane degrading soil methanotrophs and soil microbial biomass-C, N and P were investigated by selecting 6 study sites in Lucknow and Renukoot region of Uttar ...

Metabolomics of hexachlorocyclohexane (HCH) transformation: ratio of LinA to LinB determines metabolic fate of HCH isomers

Although the production and use of technical hexachlorocyclohexane (HCH) and lindane (the purified insecticidal isomer -HCH) are prohibited in most countries, residual concentrations still constitute an immense environmental burden. Many studies describe
