tailieunhanh - Antibiotics and pesticides in water and sediments from intensive shrimp farms in southern Vietnam

In recent years, shrimp farming has developed rapidly and become one of the major export sectors of Vietnam. In particular, Mekong Delta Vietnam (MDVN) accounts for over 90 % shrimp farming area in Vietnam. Shrimp industry development leads to use a large amount of antibiotics (ABs) and pesticides for disease prevention, treatment and sanitation pond. | Journal of Science and Technology 54 (4B) (2016) 146-153 ANTIBIOTICS AND PESTICIDES IN WATER AND SEDIMENTS FROM INTENSIVE SHRIMP FARMS IN SOUTHERN VIETNAM Nguyen Truong An1, 2, Dinh Quoc Tuc1, 2, *, Pham Thi Thu Hang3, Nguyen Phuoc Dan1, Le Nguyen Thi Kim1, Le Thi Bach Tuyet1, Nicolas Estoppey4, Luiz Felippe de Alencastro4 1 Faculty of Environment and Natural Resources, HoChiMinh City University of Technology, 268 Ly thuong Kiet, HCM City, Vietnam 2 3 4 Centre Asiatique de Recherche sur l’Eau, 268 Ly Thuong Kiet, HCM City, Vietnam Insitute for Environment and Resource, 142 To Hien Thanh, HoChiMinh City, Vietnam Central Environmental Laboratory, École Polytechnique Fédérale de Lausanne, Switzerland * Email:quoctuc@ Received: 15 August 2016; Accepted for publication: 10 November 2016 ABSTRACT In recent years, shrimp farming has developed rapidly and become one of the major export sectors of Vietnam. In particular, Mekong Delta Vietnam (MDVN) accounts for over 90 % shrimp farming area in Vietnam. Shrimp industry development leads to use a large amount of antibiotics (ABs) and pesticides for disease prevention, treatment and sanitation pond. These compounds are usually discharged directly into the environment through water and sludge after harvesting. The presence of antibiotics and pesticides in the environment cause negative impacts on ecosystems and human health. In this study, the passive sampling method with POCIS sampler (Polar Organic Chemical Integrative Samplers) was used to monitor the presence of 12 ABs and 2 pesticides in water of intensive shrimp ponds and the surrounding canals at Tan Tru District (Long An province) and Can Gio District (Ho Chi Minh city) following a production cycle. The results showed that ABs and pesticides were detected in water and sediment in the pond and canals in both research sites. Two pesticides (atrazine and diuron) were detected in the pond and leading canals in both study areas with low concentrations .
