To investigate the stability of seawater samples, we obtained a concentra- tion-time profile of volatile organic compounds using this method during the incubation of a seawater sample with and without the addition of HgCl2 in the dark at 48C. We found shipboard determination to be suitable and essential for the determination of un- stable compounds such as dimethyl sulfide in seawater, as the concentration of di- methyl sulfide increased considerably during the incubation of a seawater sample both with and without the addition of HgCl2. -

ACE Tips for Filing EPA ODS
Automated Commercial Environment ACE Tips for Filing EPA ODS June, 2018 Ozone-depleting substances (ODS) deplete the stratospheric ozone layer when the chlorine and bromine atoms that they contain come into contact with ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. ODS that release chlorine include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), carbon tetrachloride, and methyl chloroform. ODS that release bromine include halons and methyl bromide.
