Analysis and Testing Center, Zhejiang Branch for the country to provide dioxin monitoring services report issued by the national authority. Ningbo Municipal Environmental Monitoring Dioxin Monitoring Project include: atmospheric environmental monitoring, environmental monitoring of soil, water, environmental monitoring, monitoring of solid waste, hazardous waste (including medical waste) incineration facilities dioxin emissions monitoring, garbage incineration facilities dioxin emission monitoring. Dioxin is a chlorine-containing organic compound, is one of the highly toxic compound known to the world at present, great harm to humans! Dioxins (Dioxins) are the two oxygen atoms bonded to benzene ring compounds collectively a pair, a total of 210 kinds of different compounds, including 75 kinds of dioxins polychlorinated biphenyl (Polychlorinated dibenzo-pdioxins, referred PCDDs ) and 135 kinds of polychlorinated biphenyls furan (Polychlori-nated dib-enzofurans, referred PCDFs). 2, the source of dioxin emissions of dioxins from the solid waste incineration, waste incineration, biomass fuel combustion or heat treatment, heat treatment chemical products or production processes chlorine byproducts, incineration, chlorine bleach or disinfectant heat process. In addition automobile exhaust, the second release and solid waste incineration, paper mills, dyeing plants and other process will produce dioxin emissions. 3, Ningbo dioxins testing services range industrial emissions, industrial wastewater, ambient air, soil, water, food, plants, solid waste.
