Persistent mobile (PM) substances are being recognized as serious threats to the safety of water resources. In many cases, drinking water supplies have to be purified using expensive technologies because of contamination by PM substances. As part of this effort, a five-year wide-reaching European Research project, Zero Pollution of Persistent, Mobile substances, ZeroPM, has been launched. Fifteen partners are involved …

Natural gas deposits are source of methane released into the eastern Arctic Ocean
High levels of methane is escaping from the thawing subsea permafrost but the source(s) of that methane has long remained elusive. Now, a new study shows, for the first time, that the methane originates largely from a thermogenic (natural gas) deposit that breaks through the subsea permafrost and release into the shallow water column and the overlying atmosphere. The study …
