| Persistent organic pollutant(POPs) have inherent toxicity, persistence, accumulation and mobility. These properties results in long-term residue, which may accumulate in the food-chain, thus threat human survival and sustainable development. In this study, we investigated the emissions of main persistent organic pollutants pollution since 2010 to 2014 in Baotou city. The results indicated that dioxin-like persistent organic pollutants are the main pollutants in Baotou. The dioxin-like POPs are produced from two sectors (including steel, and iron ore sintering), which mainly distributed concentrated in Kundulun county, Guyang county and Damao County. The emissions from these industries contributed 95%of the total POPs in Baotou. In order to further control the pollution of persistent organic pollutants pollution problems, these two major industries should be a priority for improvement, based on advanced management measures and techniques. |
