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.

Detection and analysis of organochlorine pesticides (OCP) residue is getting significant research importance because of their extensive use despite their hazardous effects on the health of people and the ecosystem. Despite the implementation of regulations and bans to safeguard human health and the environment, reports frequently reveal the continued use of these harmful chemicals in quantities exceeding the recommended limits set by regulatory boards. Data on the use of OCP from India, the most populous country, and African countries is not very encouraging.

The use of pesticides in commercial farms can lead to exposure among various vulnerable groups. This study assessed the distribution, human health risks, and origins of 13 targeted organochlorine pesticides (OCPs) in soil samples from commercial farms in Southern Nigeria. Following a questionnaire survey on pesticide usage, soil samples were subjected to Soxhlet extraction and analyzed using gas chromatography-mass spectrometry.

December 2024
A method was developed for determining five organochlorine unstable pesticides (captan, chlorothalonil, dichlofluanid, folpet, and tolylfluanid) in agricultural products using GC-MS/MS. To prevent pesticide degradation, the food sample was maintained at -20℃ until the initiation of the extraction process. The sample underwent homogenization with acetonitrile and salting out using anhydrous magnesium sulfate and sodium chloride in the presence of citrate salts.
