Analysis of organochlorine pesticides in the Hindon river water, India

Pesticides are notorious contaminants due to their toxic and carcinogenic nature and, unfortunately, are distributed globally in air, water, sediment, soil and foods even to the places where they have not been used before. SPE and GC methods were developed to analyze organochlorine pesticides. The optimization was achieved by varying SPE conditions such as different pH of wastewater, flow rates of waste water, flow rates of solvents and different eluting solvents. Also optimization of GC conditions was obtained by using different columns, gases with various flow rates and temperatures. The optimized method was applied to analyze organochlorine pesticides in the Hindon river, India.
