“…The morphological characteristics of the MPs were examined using a scanning electron microscope (SEM) (TESCAN, Czech Republic). This instrument allows for the observation of detailed surface features and provides high-resolution images of the MPs (Abelouah et al, 2022;Ben-Haddad et al, 2022). Additionally, an energy dispersive X-ray spectrometry (EDS) system was incorporated into the SEM to analyze the elemental composition of the samples.…”

Plastic pollution is widely recognized as a major environmental concern due to the entry of small plastic particles into the food chain, thereby posing potential risks to human health. However, the current understanding of microplastic (MP; <5 mm) particles in livestock, which serve as an important food source, is limited. This study aims to investigate the abundance and characteristics of MPs in edible tissues of cow and sheep, namely liver, meat, and tripe, obtained from butcher shops in ve areas of Bushehr port, Iran. The average concentration of MPs in different tissues of cow and sheep were 0.14 and 0.13 items/g, respectively. Among the examined tissues, cow meat exhibited the highest concentration of MPs, with a concentration of 0.19 items/g. Nylon and ber were identi ed as the predominant polymer types and shapes of MPs found in cow and sheep tissues, respectively. Furthermore, no statistically signi cant difference was observed in MP abundance across different tissues of cow and sheep.Signi cantly, this study highlights the elevated risks associated with exposure to MPs through the consumption of edible cow and sheep tissues, particularly for children who consume meat. The results underscore the potential transfer of MPs from the environment to livestock bodies through their food, potential accumulation within their tissues, and subsequent health risks for consumers.

“…Consequently, it is important to assess water quality [23]. Water quality assessment methods often focused on physico-chemical parameters [11,14] However, with the evolution of analytical technologies, these methods have progressed to include a wider range of parameters, including organic [9] and metal contaminants [17] as well as biological indicators of aquatic ecosystem health [6]. In this regard, the objective of our work was to evaluate the physico-chemical quality and metallic contamination of the Oued Kert (Eastern Rif, Morocco), which represents a crucial water resource, requiring an in-depth assessment of its health in order to identify potential sources of contamination, and recommend…”

Water resources are vital for life, yet they are exposed to various risks. In the estern Rif of Morocco, the Oued Kert is a crucial water resource for a large population. Therefore, evaluating their health status is essential to ensure their optimal preservation. In this context, five stations (S1, S2, S3, S4, and S5) were monitored, during the four campaigns (September, December, March, and June 2022), to assess the physicochemical quality of water. In this sense, seven parameters were measured, temperature, pH, electrical conductivity (EC), Biochemical oxygen demand (BOD5), Chemical oxygen demand (COD), nitrates, and ammonium. In addition, an evaluation of metal contamination was conducted during a single campaign (May 2022) by measuring four elements (Al, Fe, Li, and Mn). The levels of electrical conductivity (greater than 3000 μS cm-1), and COD (greater than 40mg L-1 in S2, S3, and S4) indicate poor water quality, while, the average concentrations of ammonium classify these waters as of moderate quality. The results of metal contamination revealed the presence of iron (Fe) at a concentration of 1.9 mg L-1 in S5, classifying these waters as of moderate quality according to Moroccan water quality standards.

“…Only three of them carried out polymer identification (see Table 2 for details). Of these, only two [32,33] analyzed specimens from the Mediterranean Sea finding fibers and fragments composed by different polymers (see Table 2 for details). Interesting to note, these two studies are rather recent, the first of them, by Olivieri et al [33], being published in 2020.…”

Microplastics (MPs) (0.1 µm–5 mm particles) have been documented in oceans and seas. Bivalve molluscs (BMs) can accumulate MPs and transfer to humans through the food chain. BMs (especially mussels) are used to assess MPs’ contamination, but the genus Donax has not been thoroughly investigated. The aim of this study was to detect and characterize MPs in D. trunculus specimens collected along the Tuscan coast (Italy), and to assess the potential risk for consumers. The samples (~10 g of tissue and intervalval liquid from 35 specimens) were digested using a solution of 10% KOH, subjected to NaCl density separation, and filtered through 5 μm pore-size filters. All items were morphologically classified and measured, and their mean abundance (MA) was calculated. Furthermore, 20% of them were analyzed by Raman spectroscopy and, based on the obtained results, the MA was recalculated (corrected MA) and the annual human exposure was estimated. In the 39 samples analyzed, 85 items fibers (n = 45; 52.94%) and fragments (n = 40; 47.06%) were found. The MA was 0.23 ± 0.17 items/grww. Additionally, 83.33% of the items were confirmed as MPs (polyethylene and polyethylene terephthalate). Based on the correct MA (0.18 MPs/grww), D. trunculus consumers could be exposed to 19.2 MPs/per capita/year. The health risk level of MPs was classified as level III (moderate).
