| The appearance of residues of nine herbicides, amely atrazine, diuron, hexazinone, 2,4-D, linuron, ioxynil, paraquat, oxyfluorfen and picloram which are often used in weed control in sugarcane were monitored at fornightly intervals during 1995 and 1996 in groundwater from 20 boreholes representing the 10 main groundwater basins of Mauritius and in surface water at 25 locations along the rivers forming part of the grand River North West catchment area. The data showed that only the residues of the following three herbicides: atrazine, hexazinone and diuron, could be detected in freshwater sources in Mauritius. More than 60 percent of the groundwater analysed (> fifty percent for river water) in fact did not contain any herbicide residue. Even when present, the levels of the herbicide residue were mostly within the range of 0.05 to 0.5 ppb. Their highest concentration recorded never exceeded the maximum allowable limits of 3 ppb atrazine, 14 ppb diuron and 210 ppb hexzinone in groundwaters. | |
