![]() Such systems can enable the rapid and affordable testing of environmental samples without the need for reliance on external laboratories.Įlectrochemical sensors for in-field testing ![]() 4Īs a result, several research groups have now begun to develop advanced pesticide screening systems that can easily be deployed in the field. 3 At the other end of the scale, environmental soil and soil runoff samples are rarely tested at all. This may give accurate results, but it is a time-consuming process that can become quite impractical for routine screening. For pesticide residues on crops and foodstuffs, it is most common for samples to be sent away to analytical laboratories for testing. 1 With the United Nations “2030 Agenda for Sustainable Development” goals 2 placing a renewed emphasis on sustainable farming technologies and environmental safety, demand is increasing for screening techniques that can detect and monitor the presence of excess pesticide residues in the environment.ĭespite such demand, it is still relatively rare for pesticide testing to occur on-site during farming. Pesticides have become an integral part of the modern farming process due to their usefulness in preventing crop losses to pests, weeds and disease.
