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.
