“…One of the microplastics found was identified as an acrylic or alkyd chip with evidence of kaolin and styrene. Such polymers and additives are commonly used for car (Yang et al, 2012) and ship paints (Lee et al, 2021). Hence, the microplastic chip that was found in the intestine of one harbour porpoise originating from the NS could have derived from abraded ship paint.…”

Microplastic ingestion by lower trophic level organisms is well known, whereas information on microplastic ingestion, egestion and accumulation by top predators such as cetaceans is still lacking. This study investigates microplastics in intestinal samples from harbour porpoises (Phocoena phocoena) found along the coastline of Schleswig-Holstein (Germany) between 2014 and 2018. Out of 30 individuals found along the North Sea (NS) and the Baltic Sea (BS) coast, 28 specimens contained microplastic. This study found a relationship between the nutritional status of cetaceans and the amount of found microplastics. Harbour porpoises with a good or moderate nutritional status contained a higher number of microplastics, when compared with specimens in a poor nutritional status. In addition, when individuals died accidently due to suspected bycatch in gillnets, where a feeding event is highly assumed or a pharyngeal entrapment happened, the microplastic burden was higher. In total, 401 microplastics (≥100 μm), including 202 fibres and 199 fragments were found. Intestines of the specimens of the BS contained more microplastics than the ones from the NS. Differences in the share of fibres could be revealed: for BS fibres constituted 51.44% and for NS, fibres constituted 47.97%. The polymers polyester, polyethylene, polypropylene, polyamide, acrylic (with nitrile component) and an acrylic/alkyd paint chip (with styrene and kaolin components) were identified. This is the first study investigating the occurrence of microplastics in harbour porpoises from German waters and will, thus, provide valuable information on the actual burden of microplastics in cetaceans from the North and Baltic Seas.

“…The band at 872 cm –1 indicated the C–O out of plane bending. The band at 700 cm –1 confirmed a monosubstituted benzene ring . Interestingly, the depth where the paint particle was present had the highest MP concentration (30 m Jan. 2020), reaching 491 n L –1 MP (Figure b–c).…”

“…The band at 700 cm −1 confirmed a monosubstituted benzene ring. 45 Interestingly, the To confirm the causal relationship among all of the variables including MP, ships, and nutrients, we applied the partial leastsquares path modeling (PLS-PM). 20 Cause−effect relationships were established between three latent variables (LVs) in the inner model and 10 manifest variables (MVs) in the outer model (Figure 5c).…”

Microfiber Hotspots’ Association with Ships in a Remote Port before and during Covid-19

During monthly water quality monitoring of Norwegian coastal waters, the sea surface waters off Brønnøysund, a remote port in Norway, exhibited an unexpectedly high abundance of microfibers. We further conducted monitoring of microplastics and microfibers from the surface waters off the city before and during the Covid-19 pandemic. Analysis of the microfiber characteristics, which were primarily comprised of cellulosic and polyester fibers, revealed similarities with those found in the global ocean, but at concentrations that were 1–4 orders of magnitude higher, with the maximum concentration reaching 491 n/L (0.34 mg/L). Source apportionment of microfibers using multivariate analyses based on simultaneous water chemistry data showed positive correlations with ships. Contrary to previous assumptions that marine microfibers were derived from land-based sources, our findings revealed that gray water discharge from ships significantly contributed to microfibers in the oceans. The demonstrated causations using path modeling between microfibers, gray water, shipping, and noncargo shipping activities call for urgent research and regulatory actions toward addressing plastic pollution in the UN Decade of Ocean Science.

“…Lee et al presented a case report investigating three maritime collisions. After a forensic examination of paint residues recovered from the ship of interest, the other vessel(s) involved in two of the three collisions were identified [ 62 ]. The samples were taken from various collision sites (e.g., the deck, guardrails, port-side, starboard) and from 2 to 3 suspected ships per case.…”
