Hóa chất bảo vệ thực vật Clo hữu cơ trong nước và trầm tích tại trạm quan trắc môi trường biển Nha Trang trong 10 năm gần đây (2005-2014)Abstract
The analysis results of organochlorine pesticide residues at Nha Trang marine monitoring station from 2005 to 2014 showed that content of organochlorine pesticides had a gradually decreasing trend from 2005 to 2010 and then clearly increased from 2011 to 2014 in both water and sediment. Total content of organochlorine pesticides ranged from 0.33 (August 2009) to 6.18 ng/L (March 2011) in water and ranged from 0.34 (August 2009) to 9.04 ng/g (April 2013) in sediment. DDTs (include DDT and its DDE and DDD derivatives) ranged from not detected (<0.01 ng/L) to 2.21 ng/L and from 0.01 to 1.98 ng/g in water and sediment, respectively. Overall, total content of organochlorine pesticides in water and sediment in the period from February to April was often slightly higher than that from August to September. Although the organochlorine pesticide residues were found in both water and sediment during 10 years but their contents were lower than the critical values in national technical regulation for aquatic life protection.Journal
