Quantitation of Pesticides, POPs, PPCPs, & Personal Care Products in Environmental Matrices

Pesticides & Herbicides are compounds that are generally used to control weeds, mold, bacteria, insects, and rodents. Because of the widespread use of agricultural chemicals in food production, humans receive exposure to pesticide residues through their diets. While not fully understood, exposure to pesticides may interfere with neurological development and disrupt a person’s endocrine system. Endocrine disruptors are chemicals that may interfere with the body’s endocrine system – especially during prenatal and early postnatal development – include pharmaceuticals, dioxin and dioxin-like compounds, and PCBs, as well as various pesticides and plasticizers. Primarily products and byproducts of human activity, persistent organic pollutants, or POPs, can be highly toxic to humans and wildlife. Around the world, regulatory agencies have targeted 12 POPs for early action under proposed terms of a legally binding treaty. The most problematic compounds include DDT, PCBs, dioxins and furans, as well as various pesticides. While commonly reported concentrations are at low levels, Pharmaceutical and Personal Care Products can persist in the environment for months or years. They include drugs used to prevent or treat diseases as well as products such as toothpastes, deodorants, shampoos, moisturizers, lipsticks, and hair dyes, all of which eventually find their way into our sewer systems.

Agilent GC/MS and LC/MS systems perform sensitive, multi-residue analyses in complex conditions by eliminating matrix interference with Deconvolution Reporting Software (DRS) and Capillary Flow Technology (CFT). In addition, the time to create GC/QQQ pesticide methods is decreased with our comprehensive MRM database, and the GC/MS & LC/MS Pesticides Analyzers provide pre-configured solutions and tests for faster identification of target analytes. The new 5977B GC/MSD with the new high efficiency source (HES), achieves greater ion throughput, higher abundance signals and better sensitivity. The shoot less and get more approach means applying split injections with accelerated run times and this would save time and costs not only in collection and transport, but in solvent use and disposal.
