Đánh giá hàm lượng dioxin/furan từ khí thải của một số loại hình công nghiệp và dân sinh ở Việt Nam

Abstract

Dioxins and dioxin-like compounds (DLCs) are also classified by the Stockholm Convention as unintentional persistent organic pollutants (UPOPs). These toxic substances can be produced and released into the environment from many activities such as: incineration (domestic waste, industrial waste, medical waste, etc), metallurgy (steel processing, zinc recycling, aluminum production,...), manufacturing process and using organochlorine compounds (pesticides, bleach,...). The formation and emission of dioxin into the environment become more and more complex and difficult to control according to the industrial development. Therefore, the survey of dioxin emission into the environment from existing industrial and household waste treatment facilities is very necessary. On-the-spot sampling and dioxin analyzes carried out by Dioxin Analytical Laboratory and the Environmental Analysis Laboratory, the Environmental Chemistry Division, Vietnam-Russia Tropical Center. The report was built on the basis of data/information collection, analysis and assessment of dioxin emission from some types of industrial and households activities in Vietnam in the period 2012 -2017. This will be basis for assessing the concentrations of dioxin/ furan environmental pollution in order to better control environmental quality in Vietnam.
