Abstract
Hydroblasting is used to remove biofouling and exhausted antifouling paints from ship hulls. Effluents generated from this process contain paint particles, metals, and booster biocides that may have toxic effects on organisms. To understand the potential risks of effluent discharge on marine environments, we analyzed the concentrations of metals in effluents collected during the dry-dock cleaning of ship hulls by hydroblasting. Copper and zinc were the principal metals, with concentrations ranging from 1440 to 9110 mu g/L and 1800 to 22,600 mu g/L, respectively. These concentrations are sufficiently high to cause harmful effects to most marine organisms. Model predictions suggested that the effluent discharge from hydroblasting posed risks to the wider marine environment of a hullcleaning site, depending on the scale of the hull-cleaning operations and the size of the receiving environment, as well as various hydrodynamic factors. These effluents are inevitably hazardous, and their environmental release should be managed and regulated on the basis of site-specific risk assessments.
