- The Danish Ministry of the Environment is exploring measures to prohibit the discharge of scrubber water from ships, citing concerns over heavy metal and tar substance pollution in the marine environment.
- With calculations revealing significant contributions to marine pollutants from scrubber water, discussions aim to address the adverse impacts on human health and marine ecosystems.
The Danish Ministry of the Environment highlights scrubber water discharge as a major source of heavy metals and tar substances, contributing to marine pollution. Scrubbers, installed on ships to mitigate air pollution, discharge pollutants such as sulfur oxides (SOx) and particulate matter into the sea after capturing them from exhaust gases.
Impact on Marine Environment and Human Health
Excessive levels of heavy metals like lead and cadmium, along with tar substances like anthracene and benz(a)pyrene, pose significant health risks, particularly through consumption of contaminated fish and shellfish. Minister of Environment Magnus Heunicke expresses concern over the persistent circulation and accumulation of these pollutants in marine ecosystems.
Extent of Pollution and Legislative Action
Denmark ranks among the top countries globally for scrubber water emissions, with an estimated 68 million tons of pollutants discharged within 22 km of its coast. Recognizing the urgency of addressing marine pollution, the Ministry plans to convene discussions with parliamentary parties to explore legislative measures prohibiting scrubber water discharge. Concrete proposals for legislative changes will be presented to stakeholders during negotiations.
Implications for Marine Conservation
As environmentally hazardous substances emerge as a significant pressure factor on Danish marine areas, regulatory efforts to ban scrubber discharge align with broader conservation goals. By curtailing the release of pollutants into marine ecosystems, Denmark aims to safeguard marine biodiversity and protect public health from the adverse effects of marine pollution.
