Model shows how façade pollutants make it into the environment
Date:12/9/2011

Anti-fungal and anti-bacterial additives in house paint are present in dangerous quantities in the Vauchre river basin in the city of Lausanne, says a study to be presented the 9th of December, at the American Geophysical Union (AGU) conference in San Francisco. Chemicals engineered to kill microorganisms, called biocides, are added to exterior paints in order to prevent molding and plant growth. Washed off of building facades during heavy rains, however, these chemicals can be wind up in soil, groundwater and river basins where they attack bacteria, fungi and algae at the bottom of the food chain. Researchers at EPFL's Ecological Engineering Laboratory have now modeled the flow of biocides from building faades into river basins with surprising accuracy, which could lead to stricter regulations for Switzerland and abroad.

In Switzerland, biocides are present in exterior paint on some 60% of buildings and they are common worldwide. The global demand on all biocides for use in industrial and consumer goods was estimated at US$6.4 billion in 2008. Certain antifouling biocides have been phased out of use on boat hulls after being proven toxic to marine life.

The mathematical tool developed by Sylvain Coutu at EPFL accurately predicts peak concentration levels in a local river of three biocides commonly found in industrial paint: DCMU, Terbutryn and Carbendazim. Coutu predicted the concentration of these biocides after four rainstorms during the spring of 2011 and compared the numbers to actual measurements taken from the river. The model proved accurate up to a couple of nanograms per liter, an impressive feat considering the variety and complexity of variables. The model's strength comes from its ability to simplify urban surface hydraulic behaviorshow water is channeled down streets and gutters or lawns and gardensand still remain extremely accurate.

"A true toxicology report should include peak levels of concentration after rainfall, and we hav
