Study on O-NO-VOCs combined air pollution and ozone health effects in the Hexi Corridor.

In order to study the ecological and atmospheric recovery of the Hexi Corridor region, this paper analyzes the migration changes of land use characteristics and utilizes multivariate data and BenMAP-CE software to study the pollution characteristics of ozone and its precursors and the impact on human health in the Hexi Corridor region. The results showed that the increase of cultivated land area in the Hexi Corridor mainly originated from grassland. The MDA8-O concentrations met the primary and secondary standards of the Ambient Air Quality Standards on 43% and 99% of the days, respectively.
