To evaluate the environmental effectiveness of the stages of the TECA period. The contribution concentrations control measures for atmospheric pollution in Shijiazhuang, and proportions of industrial emissions to PM2:5 during the China, a large-scale controlling experiment for emission CAHP decreased noticeably compared to the NCAHP. The sources of atmospheric pollutants (i.e. a temporary emission pollutants’ emission sources during the CAHP were in effec- control action, TECA) was designed and implemented dur- tive control, especially for crustal dust and vehicles.
