The minimum release of tri-and dibutyltin has been determined for both barnacles and hydrozoans. The test method involved perfusing a known flux of biocide through a polycarbonate membrane filter with the downstream surface of the membrane exposed to a natural population of fouling organisms. No minimum release could be calculated for the dibutyltin because the flux rates were not high enough to achieve a zero fouling condition.
