ORGANOTIN PAINT RELEASE RATE METHODOLOGY

Organotin-containing paints provide excellent protection against fouling organisms, but owing to the paint's toxicity, the Navy has instead pursued development of low toxicant-release tributyltin (TBT) paints. This paper presents a reliable laboratory method to compare and rank the release rates of TBT paints. In this method, the release rate of a toxicant from a particular paint is determined by painting a surface, allowing it to dry, immersing it in water and measuring the change over time in toxicant concentration in the water. By using painted rotating cylinders, varying the number of samples collected and subsamples analyzed, and increasing the frequency of sampling, it was possible to estimate the TBT release rate to within 20%, with 90% confidence.
