Ecotoxicological impacts of refining on surface waters

For the ecotoxicological characterization of crude oil processing wastewaters we aimed to assess the chemical contaminations and the toxicity of wastewaters produced in Duna Refinery (DR).

The biodegradability of various wastewaters was also determined to estimate the concentration of recalcitrant organic substances. The efficacy – in terms of wastewater ecotoxicity – of
the new wastewater treating plant in Duna Refinery was assessed as well. Assessment of ecotoxicological impacts on surface waters as recipients of our wastewaters is a necessary contribution to reduce our ecological footprint and can help oil companies to achieve their strategic goals in terms of sustainable development.
