Corrigendum to “Accumulation of airborne microplastics on leaves of different tree species in the urban environment”

The authors regret that the printed version of the above article contained an error. The Fig. 6 of the mentioned article present the relationship between microplastic (MP) particles on the leaves of different tree species versus the MP particles found under the same trees and in the open (control) from monthly deposition samples in Portugal. The units mentioned are p·cm²·month for the MPs in the monthly deposition, and p·cm² for the MPs on leaves. However, the values presented for the monthly deposition (y axis) are in p·m². The correct and final version of the Fig. 6 follows, with the values corrected to p·cm² and the same scale for both parameters. This error did not change the conclusions or any information in the main text, since this figure and the respective values are mentioned in the main text as p·cm². The authors would like to apologise for any inconvenience caused.[Formula
