“…Supermarket live mussels (Mytilus edulis) from the UK contained 0.9 MP.g -1 (Li et al, 2018), considerably higher concentrations than those found in the present study. On the contrary, scallops and oysters from South Korean fishery markets, presented 0.08 ± 0.08 MP.g -1 and 0.07 ± 0.06 MP.g -1 respectively (Cho et al, 2019). Fibers are among the most abundant microplastic types in mollusks from various studies (Catarino et al, 2018;Li et al, 2015;Li et al, 2018;Naji et al, 2018).…”

“…Although microplastic effects and distribution in the environments have been subject of extensive research, its implications to human health and food security are still to be investigated. The presence of microplastics in market shellfish has been reported around the globe (Cho et al, 2019;Li et al, 2015;Li et al, 2018;Rochman et al, 2015; Van Cauwenberghe y Janssen, 2014). Nevertheless, there is no available information regarding seafood contamination in Peru.…”

Microplastics (< 5 mm) are ubiquitous contaminants in the marine environment. Many marine commercial species, among fish, mollusks and crustaceans, are subject to microplastic exposure through ingestion. The aims of the present study were to determine microplastic contamination in scallops from fishery markets of Lima and if microplastics are more likely to adhere to certain parts of the scallop. Argopecten purpuratus specimens were bought from fishery markets in Lima. Soft tissues were digested using 10% KOH and incubated at 60 °C overnight. An optical microscope was used to observe microplastics after vacuum filtration of the supernatant solution. Microplastic concentration, color and type were recorded. ATR-FTIR analysis determined the specific polymer types. The overall mean microplastic concentration was 2.25 ± 0.54 MP.ind-1. Fibers were the most abundant microplastic type, while red and blue were dominant colors. Mann Whitney U test indicated no significant differences (P > 0.05) of microplastic content between gonads and muscle. Microplastics in seafood and foodstuff could pose a threat to food security and human health. Still, information regarding microplastic pollution is scarce.

“…Therefore, microplastic and nanoplastic contamination is everywhere [24]. Microplastics have been found in human stool [25] and humans can consume microplastics and nanoplastics through seafood [26][27][28][29][30] and water [31][32][33][34][35][36], etc. Whether plastics will harm our health is unclear; however, the potential consequences may affect the ecological functioning of the globe and future generations of organisms ( Figure 1).…”

Plastic products are inexpensive, convenient, and are have many applications in daily life. We overuse plastic-related products and ineffectively recycle plastic that is difficult to degrade. Plastic debris can be fragmented into smaller pieces by many physical and chemical processes. Plastic debris that is fragmented into microplastics or nanoplastics has unclear effects on organismal systems. Recently, this debris was shown to affect biota and to be gradually spreading through the food chain. In addition, studies have indicated that workers in plastic-related industries develop many kinds of cancer because of chronic exposure to high levels of airborne microplastics. Microplastics and nanoplastics are everywhere now, contaminating our water, air, and food chain. In this review, we introduce a classification of plastic polymers, define microplastics and nanoplastics, identify plastics that contaminate food, describe the damage and diseases caused by microplastics and nanoplastics, and the molecular and cellular mechanisms of this damage and disease as well as solutions for their amelioration. Thus, we expect to contribute to the understanding of the effects of microplastics and nanoplastics on cellular and molecular mechanisms and the ways that the uptake of microplastics and nanoplastics are potentially dangerous to our biota. After understanding the issues, we can focus on how to handle the problems caused by plastic overuse.

“…Environmental pollutions caused by plastics wastes is one of global problems that needs serious concerns. The plastics wastes found in ground water and even inside the digestive system of sea animals in recent days, in the form of either macro-or micro-plastics (Frias & Nash, 2019), is a problem not only in Indonesia but also around the globe (Botterell et al, 2019;Cho et al, 2019;Guzzetti et al, 2018;Karthik et al, 2018;Li et al, 2019;Rainieri & Barranco, 2018;Slootmaekers et al, 2019;Teng et al, 2019;Wang et al, 2019;Windsor et al, 2019). Apart from development of recycling technologies for non-biodegradable plastics (Horodytska et al, 2018;Mwanza et al, 2018;Ragaert et al, 2017;Silveira et al, 2018;Thakur et al, 2018), development of biodegradable plastics (Chinaglia et al, 2018) is one of important solutions in coping with plastics wastes.…”

Global problems associated with conventional, non-biodegradable plastics have urged the society to use more ecofriendly biodegradable plastics. In this study, linear low-density polyethylene (LLDPE) was co-compounded with cassava-based thermoplastic starch (TPS) to prepare biodegradable plastics (i.e. plastics that can be degraded by microbes), in which three different LLDPE/TPS ratios were studied. Acetic acid was used to hydrolyze the polysaccharides by breaking the branched amylopectin that causes the TPS-containing composites brittle and stiff. The biodegradation properties of the LLDPE/TPS composites were determined by observing the level of microbial growth on the sample surface after incubation with potato dextrose agar medium that was inoculated with Penicillium sp. and Aspergillus niger. Burial test in a humid composting medium was also performed to validate the biodegradation properties. The mass change (%) was calculated in relative to the initial mass before burial test. The physical properties (tensile strength and elongation at break) of the bioplastics were determined using universal testing machine before and after burial treatment. The morphology of the sample surface was evaluated using scanning electron microscopy. The results showed that the microbial growth increases with increasing TPS content. Negative mass changes were observed on all samples that contain TPS, with increase in the magnitude with increasing TPS content. The tensile strength tends to increase in the first 28 days of burial period in a composting medium then decreases and plateaus, while the elongation at break decreases with increasing burial period. Moreover, samples that contain acetic acid showed less microbial attachment and less biodegradation compared to samples that does not contain acetic acid.
