The pesticide Dichlorodiphenyltrichloroethane (DDT) and its degradation by-products (Dichlorodiphenyldichloroethane-DDD and dichlorodiphenyldichloroethylene-DDE) are health concerns. This study aimed to investigate the impact of multigenerational exposure to traces of DDD and DDE on odontogenesis Wistar rats were allocated in 4 groups over 2 generations (F1 and F2). Water was provided ad libitum throughout the animal's life groups: control - natural water; DDD - 0.

Common carp () is extensively cultured and widely consumed in Heilongjiang Province, China. Due to the proximity of freshwater ponds to agricultural cultivated areas, these aquatic systems are inevitably influenced by the historical application of organochlorine pesticides (OCPs), due to their prolonged half-life and resistance to degradation. Gas chromatography-tandem mass spectrometry (GC-MS/MS) was utilized to quantify the levels of hexachlorocyclohexane (HCHs) and dichlorodiphenyltrichloroethane (DDTs) in the muscle tissue of cultured common carp.

Background: Despite its significant application, DDT and its metabolites pose a potential threat to the environment. Therefore, data on environmental and health concerns must thus be investigated.
Objective: The objective of this study was to assess the environmental and human health risks posed by DDT and its metabolites in Ethiopian surface waters.
Conformational Flexibility of the C-Terminal Region Influences Distal Active Site Residues Across the Tautomerase Superfamily.

Consisting of more than 11,000 members distributed over five families, the tautomerase superfamily (TSF) is a large collection of proteins with diverse biological functions. While much attention has been given to individual TSF enzymes, a majority remain structurally and functionally uncharacterized. Given its large size, studying a representative member of each family offers a viable approach for extracting mechanistic insights applicable to the entire superfamily.

The possibility of using kitchen electrolyzed water devices (EWDs) for removing residual concentrations of pesticides (malathion, fenitrothion, and p,p'-DDT) from lemon, cucumber, and carrot surfaces was tested. Three commercial devices with different parameters were tested, and their effectiveness was compared with traditional washing methods using water. Based on the results, it was found that by using EWDs, the best removal of water-soluble pesticides was achieved with malathion and fenitrothion (reduction of up to 80%).
