“…Challenges using micro-Raman spectroscopy to identify polymer type in environmental plastics have been documented (Karami et al, 2017; Lenz et al, 2015; Löder, 2015; Ribeiro-Claro et al, 2017; Shim et al, 2017; Van Cauwenberghe and Janssen, 2014; Zhao et al, 2017;). Plastic additives and pigments can mask the underlying polymer spectra while environmental degradation can weaken the Raman signal (Ribeiro-Claro et al, 2017; Van Cauwenberghe and Janssen, 2014; Yu et al, 2018; Zhao et al, 2017). Furthermore, the commercial databases referenced in this study cannot cover the variety and complexity of plastic additives (Lenz et al, 2015) and the library spectra are obtained from pure materials not previously exposed to environmental conditions resulting in decreased HQI scores.…”

“…Lenz et al (2016) found that MP concentrations in exposure studies tended to be two to seven orders of magnitude higher than MP concentrations reported from field studies. Understanding baseline environmental concentrations of MPs in a variety of ecosystems is an important step in quantifying relevant exposure risks for future lab studies that yield realistic estimates of sub lethal effects (Lenz et al, 2016; Yu et al., 2018).…”

It is widely understood that microplastics (MPs) are ubiquitous in the marine environment yet less is known about MP abundance in freshwater rivers, particularly those of the western United States. This study documents MP pollution along the Snake River (∼1735 km) and from its confluence with the Columbia River to the Pacific Ocean. Grab and plankton net samples (mesh size 100 μm) were collected from the top 25 cm of surface water every 80.5 river km. MPs were identified if they met visual criteria and were verified with the hot needle test. A small representative subset of MPs from the net samples (16.7%) were selected based on appearance for micro-Raman spectroscopy in effort to provide examples of polymer types found in this study. Seventy-five percent of grab samples and 92.8% of net samples contained MPs, with concentrations ranging from 0 to 5.405 MP L and 0 to 0.014 MP L (0 to 13.7 MP m), respectively. The majority of fragments, films and beads were between 100 μm and 333 μm. This study identifies potential hotspots of MP pollution along the Snake and Lower Columbia rivers and prioritizes areas where more intensive sampling is needed. Sites with low flow or those further down river had higher numbers and the top two hotspots were located in areas with low population density but high agricultural use. Monitoring MP abundance in freshwater systems is important for establishing baseline levels of MP pollution and can direct laboratory toxicology studies in using more environmentally relevant concentrations for a better indication of how MP pollution affects ecosystems.

“…However, FTIR presents limitations on analyzing MPs with particle size less than 10 μm. Diversity and relatively low concentration of components cause difficulty in identification and analysis, and some types of polymers are easily neglected when matching to the library standards [29].…”

“…The abundance of microplastic particles in shrimps, fishes and ducks across the ocean around the world has been reported recently [4,61,62]. As a result, daily interaction with microplastic particles in food webs was proposed through different ways such as oral, dermal and inhalational exposure [29]. Researchers hypothesize that this daily interaction could be a contributor to toxicological effects on humans.…”

Microplastic pollution represents a side-effect stemming from a global plastic waste mismanagement problem and includes degraded particles or mass produced plastic particles less than 5 mm in largest dimension. The small nature of microplastics gives this area of pollution different environmental concerns than general plastic waste in the environment. The biological toxicity of particles, their internal components, and their surface level changes all present opportunities for these particles to adversely affect the environment around them. Thus, it is necessary to review the current literature surrounding this topic and identify areas where the study of microplastic can be pushed forward. Here we present current methods in studying microplastics, some of the ways by which microplastics affect the environment and attempt to shed light on how this research can continue. In addition, we review current recycling methods developing for the processing of mixed-plastic waste. These methods, including hydrothermal processing and solvent extraction, provide a unique opportunity to separate plastic waste and improve the viability of the plastics recycling industry.

“…Maintaining the health of Bay of Bengal largely depends on understanding the threats to the ecosystem and biodiversity of the bay including climate change, overexploitation of resources, pollution and flow of pollutant containing sediments from municipal, industrial and agricultural sources. Special emphasis is needed to specially address the plastic pollution as Bangladesh which is a major contributor of (Fisner et al, 2017;Vince and Hardesty, 2017;Yu et al, 2018) plastic wastes to the Bay of Bengal.…”
