Inputs of mercury, cadmium and lead via water and air to the Greater North Sea between 1990 and 2014 dataset https://portal.medin.org.uk/portal/start.php?tpc=009_CEFASd8f25710-a22f-482c-a028-524dd2c630b4 The data shows the input loads of mercury, cadmium and lead via water and air to the Greater North Sea between 1990 and 2014. The data are separated by input loads from the UK, the OSPAR countries and other countries outside the OSPAR area. The data are presented in two CSV files. One is called data_metal inputs indicator assessment and the other in called RID_Data_Input_Hg_Cd_Pb_Indicator_Assessment. The former provides the yearly input loads of the three contaminants from the UK rivers, the atmospheric deposition from OSPAR and non-OSPAR countries. The later break down the UK specific riverine input loads including the flow rates. 20191108 20190909
