“…In contrast, a metal can, having the same brand with this study but retrieved from the sea oor of the West Paci c, only contained DMP and BHT with lower concentration of 9.0 ng/g and 18 ng/g respectively 11 . The migration rate or leaching ability of polymeric coatings may vary according to polymer thickness 22 , but the possibility of chemical additives to leach to surrounding environment has gained attention due to its weak bond to the polymer 24 .…”

Plastic debris has gained attention as anthropogenic waste in the environment, but less concerned given to metal waste despite its high abundance in aquatic environment. Metal packaging, such as can, utilizes polymeric coating films as barrier between metals and products which leads to be potential source of microplastic pollution. In this study, 27 beer cans from 16 countries for both body and lid parts as well as inside and outside layers were investigated. Despite the country’s origin, epoxy resin was the major polymeric coating used in all beer cans for lid (inside and outside) and body (inside). Whereas poly(1,2-butanediol isophthalate) was frequently used for outside layer of can body. Marketing countries turned out not specify the amount of additives used in can. DEHP and BHT were detected in almost all samples with the highest concentration of 5,300 ng/g and 520 ng/g. Despite its lower detection frequency, DOA was detected as high as 9,600 ng/g in Belgian beer can. Although being broken down, additives concentration in one environmental sample was found to be one to two orders of magnitude higher compared to the new can. This result suggests that metal debris may become source of microplastic and additives in the environment.

Despite its lower detection frequency, DOA was detected as high as 9600 ng/g in Belgian beer can. There was no apparent relationship present between the home countries of beer cans and amount of additives used. Despite of being broken down, additives concentration in one environmental sample was found to be one to two orders of magnitude higher compared to the new can. This result proved that adsorption of chemical additives took place in the environment and degraded metal debris may become source of microplastic with higher risk of additives pollution in the environment.

Microplastics (MPs) distributions have been increasingly reported in the terrestrial areas worldwide but a little information is available for ASEAN regions. In this study, 68 sediment samples of drainage channels, lakes, rivers and beach from Myanmar were collected between 2014 and 2018, and analyzed to investigate the status of MPs concentration and prevalence. The high concentrations of MPs in sediments were found in urban cities called Yangon (13,855 pieces/kg dry weight), Mandalay (11,946 pieces/kg), and Pathein (12,583 pieces/kg), which were two orders of magnitude greater than the MPs concentrations in sediments collected in rural towns called Wundwin. These results suggested that difference in high population densities and high municipal solid waste generation rate are related to the MPs contamination in sediments. Polyethylene, polypropylene and polyethylene terephthalate with fragments, lines/fibers and films/sheets were major polymers and shape in the sediment samples analyzed from Myanmar. To our knowledges, this is the first study to report the distribution of MPs in sediments from Myanmar.
