Comparative Efficacy of Potential Chemical Disinfectants for Treating Unballasted Vessels
Although NaOCl may be effective under water-only conditions, the higher concentrations required in the presence of sedi- ments may cause corrosion problems for ballast tanks, and less reactive, non-oxidizing bio- cides such as SeaKleen™ and Disinfekt 1000 ® may be better candidates for treating sedimented tanks.
Assessing the Potential Efficacy of Glutaraldehyde for Biocide Treatment of Un-ballasted Transoceanic Vessels
Experiments using material from actual NOBOB vessels generally corroborated data from the water-sediment experiments and suggest a potential treatment concentration of approximately 500 mg glutaraldehyde L−1 for short exposure periods (e.g., 24 h), indicating that the amount of sediments present in NOBOBs vessels may have a significant impact on biocide efficacy.
Chronic toxicity of glutaraldehyde: differential sensitivity of three freshwater organisms.
Data indicate that both algae and fish embryos may be particularly sensitive to long-term glutaraldehyde exposure; however, this is predicated on whether glutarhyde concentrations will achieve high enough environmental concentrations and for a sufficient period of time to elicit such effects.
Performance Evaluation in the Brazilian Public Sector
The Brazilian Public Sector is being pressured by society to provide more and better services to citizens. Thus, this research is motivated by the need to provide management tools to improve the
