Global impact of the COVID-19 lockdown on surface concentration and health risk of atmospheric benzene

Abstract P dew - 23.6  %) > - 21.9  %) > - 16.2  %) > - 15.6  %). The detrended change (P ∗ - P * = - 16.2  %) > P ∗ = - 13.9  %) > P ∗ = - 13.3  %) > P ∗ = - 6.00  %). Emission reductions derived from industrial activities and transportation were major drivers for the benzene decrease during the lockdown period. The highest decreasing ratio of ambient benzene in India might be associated with local serious benzene pollution during the business-as-usual period and restricted transportation after lockdown. Substantial decreases in atmospheric benzene levels had significant health benefits. The global average lifetime carcinogenic risk (LCR) and hazard index (HI) decreased from 4.89 × 10 - 7 and 5.90 × 10 - 3 to 4.51 × 10 - 7 and 5.40 × 10 - 3, respectively. China and India showed higher health benefits due to benzene pollution mitigation compared with other countries, highlighting the importance of benzene emission reduction.
