Abstract

THE AIM OF THIS REPORT IS TO ASSESS THE PRESENT STATUS AND THE NEED FOR FURTHER RESEARCH ON TOXICITY, SOURCES, FATE AND DETERMINATION OF TRIBUTYLTIN (TBT) IN THE ENVIRONMENT. THE EMPHASIS HAS BEEN ON INFORMATION WHICH MAY HAVE AN IMPACT ON THE REGULATIONS CONCERNING THE USE OF TBT. THE MAIN RELEASE OF TBT PROGRESSES INTO THE AQUATIC ENVIRONMENT. DEGRADATION OF TBT IN THE AQUATIC ENVIRONMENT IS A SLOW PROCESS. HALF-LIVES RANGE FROM 1 TO 3 WEEKS UNDER OPTIMAL CONDITIONS TO SEVERAL YEARS UNDER ANAEROBIC CONDITIONS. LEVELS OF TBT DETERMINED IN SURFACE WATER ARE OFTEN HIGHER THAN THE NO OBSERVED EFFECT LEVELS FOR SENSITIVE STAGES OF AQUATIC ORGANISMS. TBT ACCUMULATES IN SEWAGE SLUDGES, SEDIMENT AND BIOTA. HIGH RESIDUE LEVELS IN SEWAGE SLUDGE INDICATE SOURCES OTHER THAN ANTIFOULING PAINTS. AREAS OF FUTURE RESEARCH WHICH HAVE BEEN IDENTIFIED INCLUDE ASSESSMENT OF OTHER SOURCES, FATE OF TBT IN SEWAGE TREATMENT PLANTS, IMPROVEMENT OF THE DATABASE ON RESIDUE LEVELS OF TBT IN DIFFERENT COMPARTMENTS AND IMPACT OF TBT RELEASED FROM SEWAGE SLUDGE AND DREDGED SEDIMENTS.
