Methyl bromide and methyl chloride fluxes from soil and seawater samples under different treatment

Methyl bromide (CH3Br) and methyl chloride (CH3Cl) are major carriers of atmospheric bromine and chlorine, respectively, which can catalyze stratospheric ozone depletion. However, in our current understanding, there are missing sources associated with these two species. Here we investigated the effect of copper(II) on CH3Br and CH3Cl production from soil, seawater and model organic compounds: catechol (benzene-1,2-diol) and guaiacol (2-methoxyphenol). This work has been accepted to publish in Nature Communications with open access, entitled as "Application of copper(II)-based chemicals induces CH3Br and CH3Cl emissions from soil and seawater". On Zenodo, we are providing the source data for figure production.
