Ecotoxicological Assessment of Antifouling Biocides and Nonbiocidal Antifouling Paints

Abstract
Antifouling paint for pleasure crafts prevents algae and animals from sticking onto the hull and makes the removal of fouling easy during  cleaning. The active substances degrade rapidly and will scarcely accumulate in the environment contrary to organic tin substances. Antifouling paint containing no biocides is an experimental alternative to the use of biocides. In a leachate test, one of the experimental types of paint showed effects on algae and crustaceans.

Abstract in Danish
Bundmalinger til lystbåde skal forhindre, at alger og dyr sætter sig fast på skroget, eller de skal gøre det let at fjerne begroningen ved rensning af skroget. Aktivstofferne nedbrydes hurtigt og vil næppe blive ophobet i miljøet, som det er tilfældet for organiske tinforbindelser. Biocidfri bundmaling er et eksperimentelt alternativ til anvendelsen af biocider. For en af de eksperimentelle malingtyper blev der påvist effekter over for alger og krebsdyr i test med udvaskningsvand.
