“…These studies generally indicate that weathered particles (which have adsorbed chemicals) are more toxic than virgin particles [65][66][67]. Rios-Fuster et al (2021) [68] exposed Sparus aurata juveniles for 21 days to both virgin and weathered MPs, then examined enzyme biomarkers and social and feeding behavior. They observed increased cellular stress from virgin MPs, and a much larger response from the weathered MPs.…”

Plastics, including microplastics, have generally been regarded as harmful to organisms because of their physical characteristics. There has recently been a call to understand and regard them as persistent, bioaccumulative, and toxic. This review elaborates on the reasons that microplastics in particular should be considered as “toxic pollutants”. This view is supported by research demonstrating that they contain toxic chemicals within their structure and also adsorb additional chemicals, including polychlorinated biphenyls (PCBs), pesticides, metals, and polycyclic aromatic hydrocarbons (PAHs), from the environment. Furthermore, these chemicals can be released into tissues of animals that consume microplastics and can be responsible for the harmful effects observed on biological processes such as development, physiology, gene expression, and behavior. Leachates, weathering, and biofilm play important roles in the interactions between microplastics and biota. Global policy efforts by the United Nations Environmental Assembly via the international legally binding treaty to address global plastic pollution should consider the designation of harmful plastics (e.g., microplastics) with associated hazardous chemicals as toxic pollutants.

“…The presence of plastic in the marine environment can cause several biological and economic risks (Compa et al 2019 ; Newman et al 2015 ). In terms of biological risks, plastic litter can cause physical damage that can lead to mortality when ingested (Wilcox et al 2018 ), induce oxidative stress in mussels and fish (Capó et al 2021a , b ; Solomando et al 2020 ), and transfer hazardous chemicals such as organochlorine pesticides and polychlorinated biphenyls (Rios-Fuster et al 2021a ), all of which could potentially alter fish behaviour (Rios-Fuster et al 2021b ). Furthermore, plastic debris can act as a vector for invasive species through adhesion to their surfaces and is transported together with plastics by currents (Gregory 2009 ).…”

This study is aimed at identifying and comparing microplastics and floating marine litter along the sea surface in the marine protected area of Cabrera Archipelago Maritime Terrestrial National Park (Cabrera MPA) in the Balearic Islands. A total of 52 net surveys and 22 visual surveys were carried out between July and August in 2019 and 2020. The abundance of microplastic (MP) items was highest in the southern and eastern regions, with an average of 381,244.4 ± 1,031,082.8 items/km2 weighing an average of 927.1 ± 2731.4 g/km2. Most of these items were < 5 mm (81%) in size and were mainly composed of polyethylene and polypropylene (98%). In terms of floating marine macro litter (ML) from visual surveys, an average of 2028 ± 2084 items/km2 were observed. In this case, the majority of the ML items were plastic pieces (69%) measuring 2.5 to 50 cm. Furthermore, ML quantified by visual surveys was an order of magnitude higher than in similar studies carried out on large vessels, highlighting the importance of vessel height and speed for identifying the smallest size fractions (81%). The results of this study document the intensity of MPs and ML, primarily plastic, in coastal waters, and provide a baseline for management efforts to mitigate floating litter, in addition to raising awareness of the transferability of marine litter from other regions.

“…In this sense, given chemical properties plastic polymers can adsorb pollutants through its surface (Bakir et al, 2012). Previous studies have reported that plastic exposed to seawater have higher concentration of pollutants than virgin plastics (Hartmann et al, 2017;Liu et al, 2020;Rios-Fuster et al, 2021b) and that up to 78% of the pollutants listed as priority pollutants by the US Environmental Protection Agency were seen to be associated with stranded plastic debris (Rochman et al, 2013). Moreover, once MPs with adsorbed pollutants are ingested by organisms, gut conditions such as temperature and pH are key variables in the adsorption of these pollutants through tissues (Bakir et al, 2014).…”
