Cloning and application of epoxide hydrolases from yeasts [PDF]

, 2002
Epoxides are cyclic ethers that readily react with various nucleophilic compounds. Consequently, epoxides can be used in many chemical synthesis reactions. Two enantiomeric forms of an epoxide are possible if one of the carbon atoms is chiral. This means

Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

Food Safety and Health, Volume 4, Issue 2, Page 359-373, April 2026.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,

Combining Insecticides and Bioinputs With Eucalyptus Wood Vinegar: Effects on the Soybean Crop

Advances in Agriculture, Volume 2026, Issue 1, 2026.
The use of pesticides and bioinputs in agriculture is one of the most vital needs today to improve crop yields. A combination of pesticides and bioinputs, along with natural agents, is a viable solution to make agribusiness more eco‐friendly. Wood vinegar (WV) is a recognized agricultural input that enhances plant growth and can act as a valuable agent
