Pengaruh Pestisida dari Aktivitas Pertanian Terhadap Konsentrasi Merkuri (Hg) pada Sungai Sumur Beremas Kota Sungai Penuh

Agricultural activities cannot be separated from the use of pesticides to control plant-disturbing organisms. The mercury (Hg) content in naturally degraded on agricultural land, so it will carried off by run-off into waters. Pesticide’s activity along Sumur Beremas River has an effect increasing concentrations river. This study aims analyze pesticide and capacity river pollution loads. was analyzed using Pearson correlation. River's loads against mass balance method. results showed that had a significant increase water. greatest correlation value occurs downstream irrigation, namely 0.977, which indicates high area irrigation flow. concentration based analysis is 0.00242 ppm, exceeding standard PP no. 82 2001 Class II, 0.002 no longer able accommodate load pollution.
