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

摘要

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.
