Emissions to water by target sector in the Netherlands, 2001

The Industry and Consumers target sectors make the largest contribution to emissions to water.

Consumers and industry generate most emissions

The Industry and Consumers target sectors make the largest contribution to emissions to water.

• The Consumers target sector makes substantial contributions to total emissions of nitrogen (73%), phosphorus (71%), cadmium (67%), copper (64%), lead (54%) and zinc (50%).
• The Industry target sector is a major contributor to total emissions of chromium (80%) and nickel (68%).
• In the case of mercury and arsenic, the Trade, services and government target sector is the main contributor, with 48% and 57% respectively.

Figures are also available for total emissions to water for the years 1990-2001 for each of the substances presented here.

Definitions of the concepts of 'emission' and 'burden'

The table lists the emissions from the various sources. , including both direct emissions to surface water and indirect emissions to the sewer system. Discharges to the sewer system only reach the surface water after treatment; they are therefore indirect. Since a portion of these substances is removed by water treatment plants, the ultimate burden on surface water is lower.
