Pesticides are often chiral, and their isomers have different activity, toxicity, metabolism, and degradation properties. Perhaps, the most complex are the synthetic pyrethroid insecticides that have up to 8 stereoisomers, but not all are active. Pyrethroids are toxic to aquatic invertebrates and non-targeted species like honey bees since they persist in the environment. Extensive biological studies...
Triazoles and 3-iodo-2-propynyl butylcarbamate (IPBC) are commonly used wood preservatives active against a wide range of fungi and bacteria. As they are prone to leaching, their amounts need to be monitored by the industry to determine preservative loss from the products and for environmental impact assessment. Therefore, a liquid chromatography–electrospray–time-of-flight mass spectrometry (LC–ESI–TOFMS)...
