Abstract This chapter outlines the stages involved in chemical analysis of antifoul-
ing booster biocides, reviews the sample preparation strategies and the analytical
methods for the determination of these compounds in marine water and sediment sam-
ples. Antifouling booster biocides which are reviewed in this chapter include: Irgarol
1051, Diuron, Sea-nine 211, TCMTB (2-thiocyanomethylthiobenzothiazole), Dichloflu-
anid and Chlorothalonil. Gas chromatography-mass spectrometry (GC-MS), liquid
chromatography-mass spectrometry (LC-MS) as well as future prospects related to cur-
rent mass spectrometric techniques are outlined.
