Various investigations have demonstrated the presence of pesticides in soil, surface, and groundwater. Studies have identified an watershed area in Brasil with a high risk of soil and groundwater contamination by pesticides at the region of Ribeirao Preto, SP. Soils from zero to 20 cm, depth, surface, and groundwater were collected from the area during the period of October 1995 to July 1996, in three different points. By means of gas chromatography-mass spectrometry (GC-MS) technique the herbicides tebuthiuron, diuron, simazine, atrazine, and ametryne were analyzed according to the protocols established in literature. It were selected the following three different type of soils a) Clay, with 56.5% of clay, 15.4% of sand, and 28.1% of silt, b) Sand, with 2.4% of clay, 86.6% of sand 11.5% of silt, and c) Sandy Clay Loam, with 10.8% of clay, 83.3% of sand, and 4.7% of silt. Residue analysis for Clay soil showed high levels of diuron residues up to 351.9 ppb. during the season. The other herbicides showed less amount. The Sand, and Sandy Clay Loam soils showed a higher level of the herbicide tebuthiuron than the other herbicides at the magnitudes of 59.6 ppb. during all the months. Surface water collected all over the months showed just traces of practically all herbicides. Groundwater collected in wells surrounding the watershed showed just traces of tebuthiuron. |
