“…For instance, Lefebvre et al (2019) found that only a small fraction of all debris ingested by sardines (2.3%) and anchovies (1.5%) could be identified as microplastic particles, results that are consistent with other studies also reporting that natural fibers dominate the composition of particles ingested (Remy et al 2015; Zhao et al 2016; Catarino et al 2018; Kroon et al 2018). Misidentification is not necessarily isolated to fibers but can also include spheres.…”

“…When polymeric verification was not included, studies have often reported on the characteristics of larger fragments of plastic, typically differentiating particles associated with consumer or industrial plastic, and have included descriptions such as plastic bags, rubber elastics, rubber balloons, cigarette holders, food packaging, and so on. An overall trend is that the ingestion of microplastic particles and other debris is typically reflective of the litter in the local area in which the organisms live (Joyce et al 2002; Anastasopoulou et al 2013; Wojcik‐Fudalewska et al 2016; Zhao et al 2016; Erni‐Cassola et al 2019; Lefebvre et al 2019).…”

Microplastic particles have been observed in the environment and routinely detected in the stomachs and intestines of aquatic organisms over the last 50 yr. In the present review, information on the ingestion of plastic debris of varying sizes is collated, including data for >800 species representing approximately 87 000 individual organisms, for which plastic debris and microplastic particles have been observed in approximately 17 500, or 20%. The average reported number of microplastic particles/individual across all studies is estimated to be 4, with studies typically reporting averages ranging from 0 to 10 particles/individual. A general observation is that although strong evidence exists for the biological ingestion of microplastic particles, they do not bioaccumulate and do not appear to be subject to biomagnification as a result of trophic transfer through food webs, with >99% of observations from field‐based studies reporting that microplastic particles are located within the gastrointestinal tract. Overall, there is substantial heterogeneity in how samples are collected, processed, analyzed, and reported, causing significant challenges in attempting to assess temporal and spatial trends or helping to inform a mechanistic understanding. Nevertheless, several studies suggest that the characteristics of microplastic particles ingested by organisms are generally representative of plastic debris in the vicinity where individuals are collected. Monitoring of spatial and temporal trends of ingested microplastic particles could thus potentially be useful in assessing mitigation efforts aimed at reducing the emission of plastic and microplastic particles to the environment. The development and application of standardized analytical methods are urgently needed to better understand spatial and temporal trends. Environ Toxicol Chem 2020;39:1119–1137. © 2020 The Authors.

“…There are some studies dealing with a global estimate of floating MP in sea (Cózar et al 2014;Eriksen et al 2014). Lefebvre et al (2019) quantified MP distribution in the water column of the NW Mediterranean Sea using FTIR. Their result showed that MP were found in 93% of water column samples with an average concentration of 0.23 AE 0.20 MPÁm À3 .…”

A realistic risk assessment of microplastic pollution must stand on representative data on the abundance, size distribution, and chemical composition of polymers. Infrared spectroscopy is an indispensable tool for the analysis of microplastics (<5 mm). Spectral imaging, which provides simultaneous measurement of spatial (e.g., particle morphology) and spectroscopic information, is a promising approach toward automated microplastic analysis. This chapter aims at providing guidelines to assist with the analysis of spectral imaging data and summarizing the limitations and analytical challenges from a technical point of view. Topics, like automated particle selection for faster infrared mapping, spectral pre-processing to enhance signal quality, multivariate exploratory analysis, comprehensive reference spectral libraries, spectral matching approaches, and modelbased classification, will be exposed and some possible strategies and solutions given and discussed. We will demonstrate how to identify microplastic species by using Fourier transform infrared spectroscopy data in a stepwise manner, with detailed MATLAB command line scripts freely available to be downloaded. The reader is guided through every step and oriented in order to adapt those strategies to the user's individual case.

“…Authors found more than 90% of sampled organisms (160 individuals) contained marine litter and microplastics, ranging from 1.25 to 4.63 particles per fish, with a greater number ingested by sardines. In another study of anchovies and sardines in the Mediterranean (Gulf of Lions), Lefebvre, Saraux, Heitz, Nowaczyk, and Bonnet (2019) documented ingestion in 11% anchovies (at 0.11 ± 0.31 microplastic particles per organism) and 12% sardines (0.20 ± 0.69 particles per organism), implying variance in ingestion rates based on location.…”

This review covers selected 2019 articles on the biological effects of pollutants, including human physical disturbances, on marine and estuarine plants, animals, ecosystems, and habitats. The review, based largely on journal articles, covers field, and laboratory measurement activities (bioaccumulation of contaminants, field assessment surveys, toxicity testing, and biomarkers) as well as pollution issues of current interest including endocrine disrupters, emerging contaminants, wastewater discharges, marine debris, dredging, and disposal. Special emphasis is placed on effects of oil spills and marine debris due largely to the 2010 Deepwater Horizon oil blowout in the Gulf of Mexico and proliferation of data on the assimilation and effects of marine debris microparticulates. Several topical areas reviewed in the past (e.g., mass mortalities ocean acidification) were dropped this year. The focus of this review is on effects, not on pollutant sources, chemistry, fate, or transport. There is considerable overlap across subject areas (e.g., some bioaccumulation data may be appeared in other topical categories such as effects of wastewater discharges, or biomarker studies appearing in oil toxicity literature). Therefore, we strongly urge readers to use keyword searching of the text and references to locate related but distributed information. Although nearly 400 papers are cited, these now represent a fraction of the literature on these subjects. Use this review mainly as a starting point. And please consult the original papers before citing them.
