A Corrigendum on
Covid-19 Lockdown in Spring 2020 in France Provided Unexpected Opportunity to Assess Health Impacts of Falls in Air Pollution
by Adélaïde, L., Medina, S., Wagner, V., de Crouy-Chanel, P., Real, E., Colette, A., Couvidat, F., Bessagnet, B., Alter, M., Durou, A., Host, S., Hulin, M., Corso, M., and Pascal, M. (2021). Front. Sustain. Cities 3:643821. doi: 10.3389/frsc.2021.643821
In the original article, there was a wording error on the way that the reduction percentages of air pollutant concentrations were expressed. It is not a reduction percentage but a percentage of increase that would have been observed in the absence of lockdown.
A correction has been made to Discussion, “Summary of Findings,” first paragraph:
We replaced the following sentences: “The mean reduction in PM10 concentrations was 8.3%, with values ranging from−1.8 to 39.8% depending on the municipality. For NO2 concentrations, the mean reduction was 29.0%, with values ranging from 3.5 to 187.8% depending on the municipality.” by:
“The daily mean difference between the estimated PM10 level during lockdown and its reference (modeled concentrations without lockdown) was −8.3 μg.m−3. This difference was −2.1 μg.m−3 for NO2.”
In the original article, there was a mistake in Table 2 as published. The four columns entitled “Reduction percentage” were not defined. The corrected Table 2 appears below.
Table 2. Daily mean differences [min; max] by period, pollutant and area in France from March 16 to June 22, 2020, and from July 1, 2019 to June 30, 2020.
The authors apologize for these errors and state that this does not change the scientific conclusions of the article in any way. The original article has been updated.
