Phosphorus discharges into surface waters from point sources
|Updated: 1.12.2017 - Next update: 3.12.2018|
Point sources, such as industry and municipal wastewater treatment plants, have succeeded in considerably reducing the flow of nutrients into water bodies since the 1980s. The development was particularly rapid in the 1990s when, for instance, phosphorus discharges from industry declined by 67%. The pace has slowed slightly in the 2000s, but discharges continue decreasing.
The burdening by industry and municipalities has been reduced by improving industrial processes and boosting wastewater treatment. Better feeding techniques and reduced fish production in Finland have contributed to smaller nutrient leakage from fish farming.
