Economic Study on the Haze Management of Coal Combustion in Northeast China in Winter

Abstract

The haze weather in China's northeastern region is particularly significant in winter. To provide a healthy environment for the residents and promote healthy economic development, here we recorded the monthly change curves of SO2, PM2.5 and PM10 concentrations in multiple key cities of Northeast China, and compared those concentrations in heating seasons and non-heating seasons. Our results showed that winter heating significantly changed the concentration of SO2, PM2.5 and PM10. Furthermore, we performed a cause analysis focusing on the impact of winter coal burning on haze weather, which aimed at proposing a feasible haze control approach for the northeastern region in order to achieve the best effect of haze control with minimum cost.
