Impacts of boat paint chips on the distribution and availability of copper in an English ria

Ingestion of nylon threads by Gerreidae while using a tropical estuary as foraging grounds

“…Fisheries can be responsible for the generation of a number of types of plastic marine debris, from large items such as nets, buoys and crates to microplastics such as paint chips (Turner et al 2008) and nylon threads . The nylon fragments in the gut contents of Gerreidae species detected in this study can be classified as microplastics (< 5 mm), which can easily be ingested by benthic and demersal fishes (Possatto et al 2011, Dantas et al 2012a.…”

Labile copper and zinc fractions under different salinity conditions in a shipyard area in the patos lagoon estuary, south of Brazil

“…Turner et al 17 studied antifouling paint fragments and verified that although Cu has been found at higher concentrations in water, these high concentrations do not reflect the total concentration in the original formulations of antifouling paints because the fragments can undergo seawater leaching and because the release of Cu is gradual in water.…”

“…In total, 6 deployments were carried out, two in each seasonal period. Following a conceptual model of the distribution and behavior of dissolved metals vs. salinity in the Patos Lagoon estuary, the range of salinity was classified as low (0-6), intermediate (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25) or high (above 25). 22 In each deployment period, four devices were attached to a rope fixed on a pier at 0.5 m depth about 10 m from the margin area of the estuary.…”

“…The study concluded that DGT made it possible to determine which estuaries were more susceptible to environmental impacts. Although there are numerous studies on the leaching behavior of antifouling paints in aquatic environments and their implications for the environment, 3,4,16,17 these studies have been restricted to marinas and port areas.…”

Little boats and big concerns? Seeking a balance between ecotourism and motorboat use in Tortuguero, Costa Rica.

“…The resuspension o f bottom sediments may lead to increased erosion of bed materials (Beachler & Hill, 2003), increased internal nutrient loading (Downing, 2003;Lenzi et al, 2004), adverse effects on aquatic organisms (Bishop, 2005), increased levels of turbidity , and increased presences o f pollutants (e.g. heavy metals, sewage, agriculture runoff, PAHs, PCBs) that may be resuspended into the water column (An & Kampbell, 2003;Collins, Walling, Stroud, Robson, & Peet, 2010;Turner, Fitzer, & Glegg, 2008;Wamken, Dunn, & Teasdale, 2004;Zeman & Patterson, 2003).…”
