Quantitative Analysis of Pyrethroids in Soil and Sediment Using Triple Quad LC-MS/MS
Pyrethroid pesticides are used widely around the world as agricultural and household insecticides. Synthetic pyrethroids are slightly soluble in water and easily adsorbed in soil. In recent years, pyrethroid residues have been confirmed in soil and sediment in both agricultural and urban areas. Pyrethroids, while posing little danger to humans, exhibit a high toxicity to aquatic organisms and insects, making their impact on the ecosystem a matter of concern. Therefore, there is a need for a sensitive technique which can rapidly measure pyrethroid pesticides in soil and sediment.
Due to their low polarity, pyrethroid pesticides are typically measured by GC and GC-MS, however this Application News demonstrates simultaneous positive and negative-ion mode analysis of 14 pyrethroid pesticides using LC-MS/MS with electrospray ionization (ESI).
