Lake ecosystems can recover from mercury pollution once it stops

摘要

A study intentionally polluting a lake to measure mercury accumulation in organisms from tiny zooplankton to large fish has revealed a surprisingly rapid recovery following pollution cessation. The study, published in Nature by 26 Canadian and US scientists, was led by Paul Blanchfield with Fisheries and Oceans Canada, the International Institute for Sustainable Development (IISD) Experimental Lakes Area (Winnipeg, MB), and Queen’s University (Kingston, Ontario).
