Abstract

 In this study, we investigated the effects of using fertilizers, chemicals, and herbicides over paddy fields on contamination level of the ZILAKYROOD RIVER during 9 months of 2007-2008 period. Samples were taken in five points of the river. Phosphate, Nitrate, Ammonium, Mercury, Arsenic, Cadmium, Edifenphos, Butachlore and Dazinon of these samples were measured. The result showed that Nitrate and Ammonium were 14.45 and 0.34 ppm (below the critical level), but Phosphate fluctuated around the critical level (0.2ppm). Mercury was 5.6 ppb that was dramatically above the critical level. Arsenic and cadmium were 9.26 and 0.56 ppb respectively that were less than critical. Despite what has appeared in standars that mentions Edifenphos, Diazinon and Butachlore should not exist in surface waters, they were amounted to 2.66, 2.48 and 49.7 ppb respectively in this river.
