Pesticides are one of the pollutants that come from agricultural activities. One of them that commonly used is organochlorine insecticides. Some organochlorine insecticides belong to persistent organic pollutants (POP’s) which is a type of pollutant at issue all over the world due to its chronic, persistent and bioaccumulative character. Although the use of this insecticide has been already banned in Indonesia, there are still farmers who use this insecticide especially in the headwaters of Citarum watershed, West Java. Research / data sampling will primarily be focused on the plantation areas because the large use of insecticides in these areas due to highly-vulnerable commodity. Sampling method is refers to Determination of Pesticide in Ambient Air using High Volume Sampler and analyzed with Gas Chromatographic method (EPA Methods T04). Parameters measured are Lindan, Heptaklor, Aldrin, Endosulfan, DDT, Dieldrin, and Endrin. Determining the location of the sampling point is determined by three criteria: close to the source, a distance of 50 meters from the source, and the distance of 100 meters from the source. The measurement results showed concentrations of organochlorines were detected in the range of 0 to 0.119 mg/m3 std for particulate phase and 0 to 0.183 mg/m3 std for the gas phase, with 1 parameter Endrin exceeds quality standards. Organochlorines spreading was analyzed and converted into spray modeling with the method of atmospheric dispersion based on Geographic Information System. Spreading of organochlorines on air is affected by meteorological factors such as windspeed and direction, temperature, pressure, humidity, and also particle size of spray drift.
