Abstract
Abstract Estimation of domestic waste emissions to waters is needed for pollution assessment and modelling. We assessed quantity and location of domestic waste emissions to European waters for the 2010s. Specifically, we considered discharges of domestic waste Population Equivalent (PE, the amount of waste that equals to 60 g per day of Biochemical Oxygen Demand), and mean annual loads (t/y) of total nitrogen, total phosphorus, and 5-days Biochemical Oxygen Demand. The spatial resolution and extent of the analysis corresponded to the CCM2 River and Catchment Database for Europe, for catchments of mean area of 6.4 km 2 . The assessment is based on available European databases that allowed pinpointing waste emissions to a high spatial and conceptual resolution. Content gaps, particularly concerning domestic waste from isolated dwellings, were filled through alternative sources of information, exploiting population density and national statistics data. The dataset is of interest for assessing waste emissions to and fate through European fresh and marine waters also beyond the three pollutants evaluated in this study.
