“…Rather it can be argued that the abundance of microplastics is closely related to the extent of plastic pollution in the corresponding waters. Our results from the correlation analysis appear to be consistent with the results of Cabansag et al [19]. From a regional perspective, the samples were collected from an urban area with diverse human activity, which impacts the abundance and distribution of marine litter [20].…”

Plastic pollution has been a widespread global challenge with negative impacts on human health, environment and economies. Recently its effect on the environment and marine life has been of immense interest. This study aimed to investigate the presence of microplastics in the gut, gill and flesh of Selar Crumenophthalmus and Decapterus Macarellus from two different locations in South Maldives. A total of 56 fishes were examined from the two species and a total of 200 possible microplastic pieces were identified by visual analysis. It was found that 80% of Selar Crumenophthalmus contained micro and macroplastics, whereas these were detected in 76.2% of Decapterus Macarellus. The average abundance of microplastics in fishes was 3.3 ± 4.6 items/individual and in both species, the abundance of microplastics was highest in the gills compared to other body parts with an average abundance of 1.4 ± 2.1 items/individual. The ingested plastics mainly consisted of fragments (57.5%), fibres (41.5%) and films (1%). The particles which were identified from the analysed samples predominantly included blue (36.90%), grey (30.48%), black (17.11%) and red (9.09%) colours. The ingested plastics were found to be polyethylene (PE) and polypropylene (PP), which were determined with the use of Fourier Transform Infrared (FT-IR) Spectroscopy.

“…In free-range chicken farming, earthworms and other soil organisms that have ingested microplastics may enter the chicken through predation (Lwanga et al, 2017;Zhu et al, 2018) Microplastics, however, through free-range and caged farming both can be in ltrated through chicken feeds. Recommended feeds by the Department of Agriculture write a mixture of byproducts like seafood and crop (Li et al, 2020;Cabansag et al, 2021) where literature showed positive microplastic contamination.…”

Microplastics (MPs) have been recorded in different ecosystems, posing the risk of disrupting natural processes in the environment and causing harm to organisms that ingest them. In the Philippines, MPs have been found on various coastlines, freshwater bodies, and both fresh and saltwater creatures. Furthermore, MPs have been observed to interact with human gut microbiota and pose toxic risks in mice guts. With this, the study aimed to examine the occurrence of MPs in the entrails of Gallus gallus domesticus, the domestic chicken, which is a staple food in the Philippines. Gizzards and intestines from samples collected in seven sites across South Caloocan, Philippines were isolated and digested with a 10% potassium hydroxide solution in a 60℃ oven overnight. The resulting filtrates were then scrutinised for microplastics with a compound microscope. Microplastic contamination was found in the intestines of chicken from five sites, and in the gizzards of chicken from three sites. An intensive literature review suggests that microplastics may have entered chickens directly from the food chain or through the contaminated feeds.

Microplastic research is currently an exciting trend along with global environmental problems. The purpose of this study is to review the development of microplastic research in ASEAN. The researc uses a systematic review method by searching for the keyword “microplastic” and the name of the ASEAN country on the Google Scholar website, Science Direct, and other research paper provider websites. Papers reviewed in 2018 to August 2021 period were then classified based on the components analyzed. The results showed that based on the research location category, the majority of microplastic research was carried out in Vietnam (12/50 articles). The category of research object focused on marine organisms more than terrestrial organisms, the category of microplastic concentration varied because the microplastic sampling method was not standardized, the category of microplastic form dominated by the form of fiber; commonly found in coastal areas. The socio-economic category is not much related to the circular economy. To conclude, microplastic research still has opportunities, especially from a socio-economic perspective.
