Copper emissions from antifouling paint on recreational vessels.
Trace metals, especially copper, are commonly occurring contaminants in harbors and marinas. One source of copper to these environs is copper-based antifouling coatings used on vessel hulls. The objective of this study was to measure dissolved copper contributions from recreational vessel antifouling coatings for both passive leaching and hull cleaning activities. To accomplish this goal, three...
متن کاملHull roughness and antifouling paint
The fouling of ships and propellers results in a reduction of speed, increased fuel consumption, and consequently, losses of both time and money. The previous studies found that a speed reduction of 0.03 knots would occur due to increased friction resulting from 10μm increase in surface roughness. This would increase fuel consumption by 1%, energy savings can then be easily converted into emiss...
متن کاملA practical application of reduced-copper antifouling paint in marine biological research
Biofouling of experimental cages and other field apparatuses can be problematic for scientists and has traditionally been addressed using frequent manual removal (e.g., scraping, scrubbing). Recent environmental restrictions and legislative changes have driven the development of less hazardous antifouling products, making antifouling paint a potential alternative option to manual removal. Conse...
متن کاملLife cycle assessment of the use of marine biocides in antifouling paint A comparison of the environmental profiles between conventional copper-based and innovative Selektope paint
Cuprous oxide-based antifouling paint is now the most common type in use, especially in the shipping industry. Anti-fouling paints prevent or slow down the growth of organisms attached to the hull, in order to improve a vessel’s performance and durability. However, copper is a scarce resource and never can be retrieved or recycled after leaching into the sea. The need to protect sensitive marin...
متن کاملWorldwide occurrence and effects of antifouling paint booster biocides in the aquatic environment: a review.
Organic booster biocides were recently introduced as alternatives to organotin compounds in antifouling products, after restrictions imposed on the use of tributyltin (TBT) in 1987. Replacement products are generally based on copper metal oxides and organic biocides. This ban has led to an increase in alternative coating products containing the above biocides. The most commonly used biocides in...
