| Abstract | The Huay Kapo watershed is located in Phetchabun Province in northern Thailand. The area has always been used to cultivate maize (Zea mays L.) by the application of atrazine at 1.25-1.56 kg/ ha. The Objective of this study is to monitor atrazine concentrations in stream water and stream sediment in the Huay Kapo watershed. Based on the data monitored from 15 sample sites each month during the wet season (August-November 2008), the average atrazine concentrations in stream water and sediment samples were 4.7 ?g/L and 27.42 ?g/ kg, respectively. The content of atrazine in stream sediment was 5.87-fold significantly higher than that in the stream water. |
