Organochlorine Pesticide Residues in the Processing of Pressed Cheese

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2015
The persistence of pesticide residues in food and environment determined UN institutions to track their presence and establish rules of tolerance in foodstuffs of animal origin. Pesticide use leads to their presence as residue in foods.

Regional differences and sources of organochlorine pesticides in soils surrounding chemical industrial parks [PDF]

, 2009
Concentrations of organochlorine pesticides (OCPs; dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyclohexanes (HCHs), hexachlorobenzene (HCB)) were investigated in 105 soil samples collected in vicinity of the chemical industrial parks in Tianjin ...

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.

A GIS model-based assessment of the environmental distribution of g-hexachlorocyclohexane in European soils and waters [PDF]

, 2010
The MAPPE GIS based multimedia model is used to produce a quantitative description of the behaviour of γ-hexachlorocyclohexane (γ-HCH) in Europe, with emphasis on continental surface waters.

Crystal structure of the hexachlorocyclohexane dehydrochlorinase (LinA-type2): mutational analysis, thermostability and enantioselectivity. [PDF]

PLoS ONE, 2012
Hexachlorocyclohexane dehydrochlorinase (LinA) mediates dehydrochlorination of γ-HCH to 1, 3, 4, 6-tetrachloro-1,4-cyclohexadiene that constitutes first step of the aerobic degradation pathway. We report the 3.5 Å crystal structure of a thermostable LinA-

Comparative metagenomic analysis of soil microbial communities across three hexachlorocyclohexane contamination levels. [PDF]

PLoS ONE, 2012
This paper presents the characterization of the microbial community responsible for the in-situ bioremediation of hexachlorocyclohexane (HCH). Microbial community structure and function was analyzed using 16S rRNA amplicon and shotgun metagenomic ...

Mancozeb impairs the ultrastructure of mouse granulosa cells in a dose-dependent manner [PDF]

, 2018
Mancozeb, an ethylene bis-dithiocarbamate, is widely used as a fungicide and exerts reproductive toxicity in vivo and in vitro in mouse oocytes by altering spindle morphology and impairing the ability to fertilize.

Important amino acid residues of hexachlorocyclohexane dehydrochlorinases (LinA) for enantioselective transformation of hexachlorocyclohexane isomers [PDF]

Biodegradation, 2017
LinA-type1 and LinA-type2 are two well-characterized variants of the enzyme 'hexachlorocyclohexane (HCH)-dehydrochlorinase'. They differ from each other at ten amino acid positions and exhibit differing enantioselectivity for the transformation of the (-) and (+) enantiomers of α-HCH.
