Riverine inputs and direct discharges to Norwegian coastal waters in 2012 have been estimated in accordance with the requirements of the OSPAR Commission. Water discharges in 2012 were lower than in 2011, but higher than the 30-year normal. This caused a small but overall decrease in inputs since 2011, with an exception of zinc, which increased in the overall loads due to an increase in River Glomma. The reason is presently unknown. Analyses of data since 1990 from nine main rivers in the program revealed downward trends both for nutrients and metals, with an exception of upwards trends for ammonium in one river. Fish farming continued to be a major source of nutrients, with an increase of about 15 % of phosphorus and nitrogen loads since last year. Inputs of PCBs and the pesticide lindane were, as in previous years, insignificant
