Studies on Antifouling Paints (III)

General aspects of tin-free antifouling paints.

Occupational exposure during application and removal of antifouling paints.

Exposure data on biocides are relatively rare in published literature, especially for secondary exposure. This is also the case for antifouling exposure. Therefore, a field study was carried out measuring exposure to antifouling paints. Both primary exposure (rolling and spraying) and secondary exposure (during sand blasting) were studied. Exposure during rolling was measured in boatyards where...

Controlling Marine Fouling with Antifouling Paints and Underwater Hull Cleaning

trolling marine fouling on ships’ hulls has been considered essential since the earliest days of marine transport. It has been estimated that without any attempt to control fouling, shipping would require 40% more power, equal to about 72 million tonnes of additional fuel per year.1 Therefore, without an effective antifouling system, today’s marine transport industry would undoubtedly grind to ...

Effect of organotin compounds (TeT) used in antifouling paints on cultured marine molluscs - a literature study

Organotin salts, used as antilouling substances have a deleterious effect on the environment. particularly on molluscs and especially on the Japanese oyster Crassostrea gigas. A synthesis 01 the effects 01 tributyltin (TBT) on cultured molluscs reveals the lollowing effects: 1) acute and chronic loxicity to the adults; 2) accumulation in the f1esh 01 the adults; 3) perturbation 01 reproduction ...

XRF measurements of tin, copper and zinc in antifouling paints coated on leisure boats.

Tributyltin (TBT) and other organotin compounds have been restricted for use on leisure boats since 1989 in the EU. Nonetheless, release of TBT is observed from leisure boats during hull maintenance work, such as pressure hosing. In this work, we used a handheld X-ray Fluorescence analyser (XRF) calibrated for antifouling paint matrixes to measure tin, copper and zinc in antifouling paints coat...
