“…Although these types of materials have not been investigated from an ecotoxicological point of view, recent studies raised environmental concerns regarding paint particles (<5 mm) containing Cu nanoparticle biocides ( Torres and De-la-Torre, 2021b ). In particular, these types of painting have been reported to cause mortality to sediment-dwelling species at environmentally relevant concentrations, such as Hediste diversicolor (LC 50-5d = 19.9 g L −1 ) and the Common cockle (LC 50-5d = 2.3 g L −1 ) ( Muller-Karanassos et al, 2021 ). These secondary products derived from PPE pollution could represent considerable ecotoxicological effects.…”

Personal protective equipment (PPE) pollution has become one of the most pending environmental challenges resulting from the pandemic. While various studies investigated PPE pollution in the marine environment, freshwater bodies have been largely overlooked. In the present study, PPE monitoring was carried out in the vicinity of Lake Tana, the largest lake in Ethiopia. PPE density, types, and chemical composition (FTIR spectroscopy) were reported. A total of 221 PPEs were identified with a density ranging from 1.22 × 10 −5 PPE m −2 (control site S1) to 2.88× 10 −4 PPE m −2 with a mean density of 1.54 × 10 −4 ± 2.58 × 10 −5 PPE m −2 . Mismanaged PPE waste was found in all the sampling sites, mostly consisting of surgical face masks (93.7%). Statistical analyzes revealed significantly higher PPE densities in sites where several recreational, touristic, and commercial activities take place, thus, revealing the main sources of PPE pollution. Furthermore, polypropylene and polyester fabrics were identified as the main components of surgical and reusable cloth masks, respectively. Given the hazard that PPEs represent to aquatic biota (e.g., entanglement, ingestion) and their ability to release microplastics (MPs), it is necessary to implement sufficient solid waste management plans and infrastructure where lake activities take place. Additionally, local authorities must promote and ensure sustainable tourism in order to maintain the ecosystems in Lake Tana. Prospective research priorities regarding the colonization and degradation of PPE, as well as the release of toxic chemicals, were identified and discussed.

“…85 Paint particles can affect the health of benthic biota due to either direct ingestion or exposure to leached compounds. 86 To understand the full extent of ship paint MP pollution in the Southern Ocean surrounding Antarctica, further research is needed, particularly targeting smaller particles and sediments, including the evaluation of the polymeric binder as well as inorganic pigments and fillers of putative paint particles to discriminate possible sources.…”

Microplastic (MP) pollution has been found in the Southern Ocean surrounding Antarctica, but many local regions within this vast area remain uninvestigated. The remote Weddell Sea contributes to the global thermohaline circulation, and one of the two Antarctic gyres is located in that region. In the present study, we evaluate MP (>300 μm) concentration and composition in surface (n = 34) and subsurface water samples (n = 79, ∼11.2 m depth) of the Weddell Sea. All putative MP were analyzed by attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. MP was found in 65% of surface and 11.4% of subsurface samples, with mean (±standard deviation (SD)) concentrations of 0.01 (±0.01 SD) MP m–3 and 0.04 (±0.1 SD) MP m–3, respectively, being within the range of previously reported values for regions south of the Polar Front. Additionally, we aimed to determine whether identified paint fragments (n = 394) derive from the research vessel. Environmentally sampled fragments (n = 101) with similar ATR-FTIR spectra to reference paints from the research vessel and fresh paint references generated in the laboratory were further subjected to micro-X-ray fluorescence spectroscopy (μXRF) to compare their elemental composition. This revealed that 45.5% of all recovered MP derived from vessel-induced contamination. However, 11% of the measured fragments could be distinguished from the reference paints via their elemental composition. This study demonstrates that differentiation based purely on visual characteristics and FTIR spectroscopy might not be sufficient for accurately determining sample contamination sources.

“…By contrast, poisoning of birds through the ingestion of leaded paint particles has been documented in situ ( Molnar, 1983 ; Finkelstein et al., 2003 ) and concentrations of antifouling paint representative of those encountered in contaminated harbour sediments have been shown to elicit toxic responses in epibenthic copepods, crustaceans and macroinvertebrates in controlled laboratory exposures. For example, Muller-Karanassos et al. (2021) report 5-day lethal and effects concentrations (LC 50 and EC 50 , respectively) for size-fractionated particles (100 μm to 1 mm) derived from a modern Cu-based antifouling paint of 19.9 and 14.6 g per L of estuarine sediment, respectively, for the ragworm, Hediste diversicolor , and 2.3 g L −1 and 1.4 g L −1 , respectively, for the common cockle, Cerrastoderma edule .…”

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.
