Mapping global human dependence on marine ecosystems
(Journal article; Peer reviewed, 2019)Many human populations are dependent on marine ecosystems for a range of benefits, but we understand little about where and to what degree people rely on these ecosystem services. We created a new conceptual model to map ... -
Mapping microplastics in sludge
(NIVA-rapport;7215, Research report, 2017)The main objective of this project was to characterize microplastics in sewage sludge from Norwegian domestic wastewater treatment plants applying different wastewater and sludge treatment technologies. WWTPs were selected ... -
Mapping of contamination problem areas in Europe’s seas using a multi-metric indicator-based assessment tool
(Peer reviewed; Journal article, 2022)We report identification and mapping of areas in Europe’s seas and coastal areas impacted by contaminants, i.e., areas with concentrations above internationally agreed threshold values. The study is based on (1) a ... -
Mapping of Critical Loads and Critical Load Exceedances in the Killarney Provincial Park, Ontario, Canada
(NIVA-rapport;3889, Research report, 1998)Calculations of critical loads for inputs of strong acids to lakes and exceedances of critical load can be a useful tool for the management of polluted areas. In Sudbury, Canada, large emissions of sulfur dioxide have ... -
