17 April 2019. Rob Mason was a co-author of a recent publication in Science of the Total Environment (How closely do mercury trends in fish and other aquatic wildlife track those in the atmosphere? – Implications for evaluating the effectiveness of the Minamata Convention) that provided a review of the potential timescale and magnitude of response of fish in different ecosystems to changes in inputs of mercury to the atmosphere from anthropogenic activities. The paper is a synthesis of information gathered for the 2018 Global Mercury Assessment Report, published by the United Nations Environmental Program as part of the activities of the Minamata Convention on Mercury, a globally binding treaty that has been initiated to reduce anthropogenic mercury emissions to the biosphere.
