“…However, residues of the antifouling paint could be generated and exposed to sediment layers in aquatic systems, which eventually leads to a potential threat to benthic invertebrates [14]. Another conventional method for the antifouling effect is to coat antifouling substances based on copper and/or organotin compounds [15].…”

Effective Harmful Organism Management I: Fabrication of Facile and Robust Superhydrophobic Coating on Fabric

Advances in harmful organism management are highly demanding due to the toxicity of conventional coating approaches. Exploiting biomimetic superhydrophobicity could be a promising alternative on account of its cost-effectiveness and eco-friendliness. Here, we introduce a facile method to fabricate a robust superhydrophobic coating on a fabric substrate. This is achieved by sequentially spraying TiO2-epoxy resin nanocomposite material and fluorocarbon-silane modified SiO2 nanoparticles (FC-silane SiO2 NPs). The superhydrophobicity is attributed to the nanoparticles constituting a micro/nano hierarchical structure and the fluorocarbon of the modified SiO2 NPs lowering the surface energy. The epoxy resin embedded in the coating layer plays an important role in improving the robustness. The robustness of the superhydrophobic surface is demonstrated by measuring the water slide angle of surfaces that are subject to salty water at 500 rpm stirring condition for up to 13 days. This study focuses on ensuring the superhydrophobicity and robustness of the coating surface, which is preliminary work for the practical management of macrofoulers. Based on this work, we will perform practical harmful organism management in seawater as a second research subject.

“…Some degradable A/F biocides such as copper/zinc pyrithione have been approved for use, in EU for example (Biocidal Products Committee 2014), and the heavy metals such as copper or zinc deriving from the biocides are accumulated in aquatic environments. The particles from A/F paints (APP) may also become a source of pollution in the vicinity of ship docks and marinas, due to their environmental behavior and the ecological effects they produce in sediments (Turner 2010;Turner et al 2008;Soroldoni et al 2020). Sediment dwelling organisms are known to be of high exposure risk to many contaminants (Kasiotis 2009;Alonso-Hernandez et al 2014).…”

This study sought to clarify whether suspended particles containing high Cu concentrations are present in the sea-surface microlayer (S-SML). For this reason, suspended particles (10-2000 µm) in the S-SML were collected periodically from a ship mooring pond during 2018-2020, and the acid-soluble Cu concentration in the suspended particles was measured as particulate Cu (P-Cu). The highest concentration of P-Cu in the S-SML of the pond was 75 µg L -1 with a 90th percentile value of 2.5 µg L -1 . This is below P-Cu values reported for the S-SML in North American ports, but 140 times higher than this found in bulk seawater in the Atlantic Ocean. The highest P-Cu concentration in the S-SML of non-organism (abiotic) origin was 17 µg L -1 , and the abiotic P-Cu to P-Cu ratio varied from 0.2 to 100%, likely depending on the quality and quantity of biogenic material in the S-SML samples. It is assumed that the S-SML particles examined here contain high Cu concentrations originating from ship antifouling paints.

“…(2017) report a significant decrease in fecundity for epibenthic copepods exposed to 0.01% of modern, Cu-based antifouling paint particles (< 63 μm) in estuarine sediment and an LC 50 arising from the elutriate of a preparation equivalent to 0.14% of paint. Soroldoni et al. (2020) subsequently demonstrated 10-day LC 50 values for benthic microcrustaceans exposed to estuarine sediment spiked with fractionated antifouling paint particles of 0.16 to 0.45% by mass of sediment.…”

Highlights Paint particles are often overlooked in the micro-debris and microplastic pools. The sources, behaviour and impacts of paint in the marine environment are reviewed. Paint particle emissions may be as high as 35% of the synthetic micro-debris input. Paint is regularly detected in sea surface trawls, sediments and animal digestive tracts. Hazardous additives in micro-paint particles render them more harmful than microplastics.
