“…A higher MP occurrence (95%) was reported by Heshmati et al [ 49 ] from the Qarasu River in Iran. In contrast, Park et al [ 50 ] reported a 100% prevalence in freshwater species from the River Han in South Korea. Another study on the Parana River in Argentina by Blettler et al [ 51 ] also recorded a 100% prevalence.…”

“…For example, zinc chloride (ZnCl 2 ) has a high density (1.5 g cm −3 ) and can extract high-density MPs such as high-density polyethylene (HDPE) and poly(ethylene terephthalate) (PET). Researchers A study by Park et al 36 found that 10% KOH aids the digestion of MPs in fish from the Han River in South Korea. Enzymatic digestion has also been employed by certain researchers to break down organic materials in the food matrix.…”

This Review critically focuses on the current challenges in analyzing microplastics (MPs) in solid and liquid samples, particularly in food products with the greatest potential for MPs contamination. Our literature review revealed that many researchers have used mild to harsh chemical solutions for the digestion of interfering matrixes during the extraction of MPs from several types of food samples. Polyethylene, polystyrene, poly(ethylene terephthalate), and polypropylene are the four main types of polymers found in food. MPs identification techniques such as FT-IR, SEM, and Raman spectroscopy are also discussed in detail. This Review narrows the gap in selecting a suitable membrane for the extraction and identification of MPs from various types of food matrixes. The present review generalizes the combination of techniques that are better suited for the detection of MPs in food and provides awareness of the presence of MPs in food samples and their toxicities.

“…Information about length and weight is used to nd out the total weight and total length of individual sh (Koutrakis and Tsikliras 2003). Information regarding the length and weight is used to determine the fatness, health, and status of sh in a particular habitat (Park et al 2022).…”

The study examined the growth and reproductive characteristics of Rastrelliger kanagurta, a commercially sold fish in Gawadar, Balochistan. A total of 600 samples were collected from 2017 to 2019. The growth, reproductive characteristics, and wellbeing were assessed using length-weight relationship, fecundity, gonadosomatic index (GSI), and condition factors. Water quality parameters were assessed to estimate temporal variations in the quality of water inhabiting R. kanagurta. The results of LWR indicated that fish showed positive allometric growth (b<3) in both years of study. The mean Fulton’s condition factor (kc) ranged from 1 to 1.33 (2017–2018) and from 1 to 1.34 (2018–2019), while the relative condition factor (kn) was equal to 1 during the study period. The mean fecundity was 51450.4 eggs (2017–2018) and 46671.1 eggs (2018–2019). The highest fecundity was seen in June and July, while the lowest fecundity was observed in February. The GSI values ranged from 2-31 to 12.87 (2017-2018) and from 1.03 to 9.47 (2018-2019), with two spawning seasons: the first occurs from March to August, and the second takes place from August to October, respectively. The analyzed water quality parameters expect DO were in the range acquired for the better growth of fish. A positive correlation was observed between fecundity, body length, weight, ovary weight, and water quality parameters. Temporal variations in the studied parameters were statistically non-significant (p<0.05) except temperature and DO. The conditional factors were greater than the well-being value of one. The results concluded that R. kanagurta had good habitat adaptation.
