Kinetic and sequence-structure-function analysis of known LinA variants with different hexachlorocyclohexane isomers. [PDF]

PLoS ONE, 2011
BACKGROUND: Here we report specific activities of all seven naturally occurring LinA variants towards three different isomers, α, γ and δ, of a priority persistent pollutant, hexachlorocyclohexane (HCH).

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-

Oxidative Damage, Energy Imbalance, and Behavioral Disruptions in Girardia tigrina Exposed to Treated Sewage Effluents

Environmental Toxicology, EarlyView.
ABSTRACT This study assessed the ecotoxicological effects of treated sewage on the freshwater planarian Girardia tigrina, integrating biochemical, energetic, and behavioral biomarkers. Planarians were exposed for 48 h to different concentrations of treated sewage (12.5%, 25%, 50%, and 100%) and compared to controls using commercial water and water from

Greater cognitive decline with aging among elders with high serum concentrations of organochlorine pesticides. [PDF]

PLoS ONE, 2015
Although cognitive decline is very common in elders, age-related cognitive decline substantially differs among elders and the determinants of the differences in age-related cognitive decline are unclear.

Satire and Silence under Authoritarian Rule: Cotton and Pesticide Perceptions in Tajikistan

Journal of Agrarian Change, Volume 26, Issue 4, October 2026.
ABSTRACT Over the past 70 years, agricultural chemicals have become a mainstay of cotton farming in Central Asia. This growing reliance on agrochemicals has not remained uncontested. This article analyses the politics of pesticides in Soviet and post‐Soviet Tajikistan by examining how, and to what extent, pesticides have featured in graphic satire, an ...

Volatile Organic Compounds in Rainwater: A New Frontier in Atmosphere–Biosphere Interactions

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Rainwater is a key vector of atmospheric deposition, linking the atmosphere with terrestrial and aquatic ecosystems. While the inorganic chemistry of precipitation (dominated by sulfate, nitrate, ammonium, and trace metals) has been extensively studied, organic compounds in rainwater have received less attention, and Volatile Organic Compounds
