“…However, SQG have several limitations in assessing the magnitude of anthropogenic chemical pollution and the potential for eliciting adverse biological effects in aquatic organisms (McCauley et al, 2000;Birch, 2018). SQG are based on acute toxicity in invertebrates, which might not be adequate for protecting higher trophic level organisms such as fish, seabirds, and marine mammals (Sanganyado et al, 2021). Using a habitat-based food web model, a previous study found PCB concentrations in marine sediments that could protect killer whales against adverse effects were 0.004 -0.39 ng g − 1 (Alava et al, 2012).…”

“…Most of these pollutants are persistent in the environment and accumulate in the soil and sediment of rivers; they can be easily transported from their source areas over long distances. They accumulate along trophic chains, posing serious risks to the health of various species, especially those at the top of the food chain (Sanganyado et al ., 2020).…”

Pollutants and biological data were assessed in surface sediments from an urbanized and hypereutrophic bay in Brazil. The surface sediment samples contained coarse to fine grains. The samples were analysed using four tools that followed standard methodologies. Pollutants were observed in several sediment samples, as was observed with the pseudototal trace elements. Dinoflagellate cysts showed an indication of a eutrophic environment with the presence of L. machaerophorum. On the other hand, the Vibrio fischeri bioassay demonstrated high toxicity in this area. The obtained data demonstrate the high level of pollution in the area due to a high input of untreated sewage and a large number of industries close to the collection points. Therefore, the Canal do Cunha basin can be considered an outflow area for different pollutant residues being transported into Guanabara Bay.

“…Owing to their bright colour and tiny size, microplastics are ingested by invertebrates and vertebrates (Wang et al, 2020), introducing POPs into the food web (Li et al, 2020;Moore, 2008). Biomagnification occurs at higher up trophic levels (Setala et al, 2014), threatening fish and other marine organisms, even human beings (Sanganyado et al, 2020). Microplastics have been reported to decrease survival and lower fecundity in Tigriopus japonicas Mori 1938 (Lee et al, 2013), cause analogous embryonic development in Lytechinus variegatus Lamark 1938 (Nobre et al, 2015).…”

Whereas the Western Indian Ocean (WIO) has been reported to be polluted with microplastics (MPs). Documented information on the specific polymeric composition of these particles in seawater and sediments along the Kenya coast is insufficient. This study assessed the abundance and types of microplastic polymers in the region. Microplastics were sampled from surface water using 500µm neuston nets and from the sediments using a 3.6 cm-diameter corer. Fourier Transform Infrared (FTIR) spectroscopy, Differential Scanning Calorimetry (DSC) and Nuclear Magnetic Resonance (NMR) were used to identify the MPs polymer types. Four polymer types were identified of which, high-density polyethene was the most abundant at 38.3%, followed by polypropylene (34.6%), low-density polyethene (27.1 %), and medium density polyethene (17.1%). The results demonstrate the extent of exposure to microplastics of the region's ecosystems and provide the impetus for proper policy briefs regarding the management and disposal of plastic waste, protect and save oceans rich in biodiversity for sustainable development.
