Handling of pesticide residues in Nam Linh - Nam Dan
In the 80s of the last century, due to the requirements of production and life, a pesticide warehouse was built in the area of hamlet 4, Nam Linh commune (Nam Dan). In 1995, people dug a pond and dumped soil around it, polluting an area of up to 750 square meters. Over the years, although this warehouse is no longer in use, this pesticide residue point has always been considered a hot spot of environmental pollution, severely affecting the lives and health of people in the area.
(Baonghean) -In the 80s of the last century, due to the requirements of production and life, a pesticide warehouse was built in the area at hamlet 4, Nam Linh commune (Nam Dan). In 1995, people dug a pond and dumped soil around it, causing the area to be polluted up to 750m.2. Over the years, although this pesticide warehouse is no longer in use, this pesticide residue site has always been considered a hot spot for environmental pollution, severely affecting the lives and health of people in the area.
Ms. Nguyen Thi Sen in Hamlet 4 (Nam Linh) said: “Both my parents died of cancer. In 2009, I felt tired and had a persistent cough, so I went to the doctor and was diagnosed with lung cancer. I hope the government will take drastic measures to deal with this so that people in the hamlet will not have to continue to suffer the pain like my family.” Many other households in the area are also unfortunate because of incurable diseases. Both Mr. Nguyen Dinh Can and his daughter (living next to the area contaminated with pesticides) died of stomach cancer, and his youngest daughter is currently being treated in Hanoi for kidney failure. Or Mr. Dinh Xuan Ly had a son who died of a stroke... Many others are struggling with diseases such as diabetes, liver failure, and kidney failure. Along with that, hundreds of square meters of contaminated land have caused heavy damage to agricultural production and livestock raising in the area.
Treatment of pesticide residues in Nam Linh using improved oxidation technology
In 2011, the province treated over 350 m2Pesticide contaminated land in Nam Linh. However, in hamlet 4 there are still over 400 m2The soil is seriously polluted by the residue of pesticide warehouses. The method of using "improved oxidation" technology of the Vietnam Academy of Agricultural Sciences is considered a breakthrough in thoroughly handling this problem. This is a method using "improved oxidation" technology, technical staff of the Vietnam Academy of Agricultural Sciences dug down 2.5m, using about 10 tons of solvents and oxidizing agents to treat the pollution. The results are very positive, with a safety rate on the soil reaching 99%. According to Mr. Nguyen Van Bo - Director of the Vietnam Academy of Agricultural Sciences: This is the most feasible technology that we can use to treat pesticide residues at the present time. In fact, the "hot spot" of pollution in Nam Linh commune, Nam Dan district has been safely treated, contributing significantly to ensuring people's lives and restoring local agricultural production.
In Nam Dan district, there are currently 7 serious pollution spots discovered, not to mention a number of long-term fertilizer and pesticide storage locations of agricultural cooperatives that are also threatening the lives and production of the people every day. Mr. Dinh Xuan Que - Vice Chairman of Nam Dan District People's Committee, said: "The successful treatment of pollution at the pesticide warehouse in Hamlet 4 (Nam Linh) has helped people feel more secure, and at the same time created favorable conditions for the locality to focus on directing the resolution of pollution spots in the area. However, with many "hot spots" like today, to spread pollution, improve the living environment and production for the people, we really need the attention and help of the State".
According to information from the provincial Plant Protection Department, Nghe An currently has 913 contaminated locations containing pesticides, of which 165 locations have a very high potential for pollution, located in locations with many types of highly toxic pesticide residues, with a storage volume of about 2 tons/warehouse/year, long storage time and large spillages, near residential areas.
In recent times, with the support of the State, our province has built surrounding walls, built temporary landfills with cement tanks or tarpaulins to prevent seepage and pollution of underground water sources, and built two-level incinerators with toxic gas control at pesticide contaminated sites. However, that is only a temporary solution, not a complete solution to the pollution problem. In that context, the method of treating pesticide pollution using "Improved Oxidation Technology" of the Vietnam Academy of Agricultural Sciences, which was successfully implemented in Nam Dan recently, is truly an important opening direction, helping our province to soon completely resolve pesticide contaminated sites in the area.
