Abstract: Plastic recycling in Minh Khai village started in the 1980s and was expanded in scale and size in the 1990s. New job creation significantly contributed to the promotion of wealth and better living standards for villagers. Nevertheless, residents in Minh Khai village have had to face serious environmental problems. This research aimed to study the environmental impacts from plastic recycling processes, and to determine how it affects the health of villagers. Two methods of data collection were performed consisting of water sampling analysis and the collection of questionnaires and in-depth interviews. There were 7 water samples taken, including: 2 surface water samples, 1 leachate sample from open landfill and 4 groundwater samples from deep-dug wells. Water samples were analyzed for the following parameters: pH, temperature, DO, turbidity, Coliforms, BOD5, COD, TSS, As, Hg and Pb. Thirty-four households and 3 government officers were respondents of structured questionnaires and in-depth interviews, respectively. The results showed that surface water, groundwater and leachate were polluted by wastewater from plastic recycling processes due to the direct discharge of wastewater into the canals in the village. BOD5 and COD from surface water exceeded the standard by 10 times and 5 times, respectively. Leachate and groundwater also had a problem with Pb contamination, which was higher than the standard by about 2-3 times. The villagers have had to deal with some diseases as well, such as respiratory problems, decline of hearing ability, digestive disorders and trachoma. The percentage of people who got diseases in Minh Khai village was higher than other agricultural villages by about 20–25 percent. Life span of the villagers is low, about 60.3 years old, especially life span of males, which is 52.5 years old, compared to 71.6 years old for the average Vietnamese life span. Therefore, this study has proposed some suggestions in order to improve environmental quality and to ensure living conditions and health of villagers, such as the implementation of a proposed environmental management system with specified mission and responsibility, promotion of environmental programs, improvement of central and local responsibility, regulation and innovative enforcement, and industrial zone planning.
