In evaluating blood samples from newborns and their mothers living in agricultural areas, researchers find altered levels of enzymes caused by oxidative stress.

The structure of O-ethyl N-phenyl­thio­carbamate has been redetermined. Layers of hy­dro­gen-bonded dimers lie parallel to (031). A refinement using nonspherical scattering factors greatly reduced the number and severity of badly-fitting reflections.

(Beyond Pesticides, February 10, 2022) A National Institute of Environmental Health Sciences (NIEHS)-funded study finds that patterns of pesticide exposure among farmers have geographical and temporal significance. Specific use of and exposure to organophosphate and carbamate chemicals decrease enzyme activity within the body, resulting in greater health anomalies among farmers, especially during agricultural seasons. The use of xenobiotic (foreign chemical compounds) substances like pesticides and fertilizers in agriculture are increasing. Thus, those working with and around these toxicants must have protection. Considering that agricultural workers often experience pesticide exposure at higher rates due to occupation, long-term research must identify potential health concerns surrounding common pesticides. The study author, Dana Barr, Ph.D., states, “The majority of farmers in this study reported that they had at least one health symptom associated with pesticide intoxication. This investigation can be used to promote safer use of pesticides among farmers and mitigate exposure among residents living near a rice field. The findings will be critical for establishing and launching several preventive programs in the future.” Researchers evaluated the health effects of pesticide exposure among a cohort of farmers in Thailand during inactive and active rice farming periods. Using geographic information system (GIS) mapping, researchers compared […]

A 3,6-disubstituted 1,2,4,5-tetra­zine was synthesized and characterized by single-crystal X-ray diffraction, revealing a complex hydrogen-bonded network with inter­actions between tetra­zine N atoms and hydroxyl groups, thereby complementing the only scarcely explored features of tetra­zines in the solid state.
