摘要：

A study was carried out in an experimental citrus grove in order to determine the presence and movement of pesticides along the unsaturated zone before reaching the aquifer. Several pesticides widely used in the area (dicofol, tetradifon, dimethoate, fenitrothion, methidathion and MCPA) were spread on the grove at their recommended doses. Samples of soil solution were collected at several depths (0.2, 0.5, 1.5, 2.5 and 3.4 m) by using pressure-vacuum soil water samplers. Analysis of pesticides in water samples were carried out by high resolution gas-liquid chromatography using a dual detection system with ECD and NPD, capillary column (Ultra 2, Hewlett-Packard, 25 m, 0.20 mm i.d., 0.33 mum film thickness) and splitless injection system. High performance liquid chromatography with UV-Vis detection and reversed phase column was used for the determination of MCPA. Sampling and analysis were performed monthly, starting in December 1990. Samples of groundwater from several wells in an area within 5 km around the experimental grove were also analyzed for pesticides in order to complete data from this study. Preliminary results obtained in the analysis of soil solution water from unsaturated zone and groundwater samples are presented in this paper.
