Los microplásticos (MPs) en canales de riego han sido poco estudiadas en Perú. El objetivo de este estudio fue determinar la abundancia y características (tamaño, color y forma) de MPs en sedimentos superficiales de canales de tierra para riego (Yuncaypara y Mejorada) ubicados en el centro poblado de Madeán, distrito de Madeán, provincia de Yauyos, región Lima, Perú. Se muestrearon en cada sitio por triplicado, 1 sitio en canal Mejorada (CM) y 2 sitios en canal Yuncaypara (CY1 y CY2). La separación se realizó con solución salina de alta densidad (ZnCl , cloruro de zinc). Los resultados mostraron la 2 abundancia en CM, CY1 y CY2 que fueron 111,11 ± 19,25; 566,67 ± 88,19 y 66,66 ± 0,00 Ítems/kg de sedimento seco, respectivamente. Las características de tamaño, color y forma, los predominantes fueron pequeños MPs (6-1000 μm), azul y fragmento, respectivamente. No se encontró pellet y espuma. Se concluye que hay presencia y contaminación por MPs en sedimentos superficiales de canales de tierra para riego. Los MPs secundarios fueron los únicos encontrados y a cercanía del sitio de muestreo con el centro poblado presenta mayor abundancia de MPs.

“…Plastic waste in aquatic ecosystems has become a local, regional, and global issue. Several million tons of plastic waste are released into the marine environment through rivers and atmospheric particles ( Chen et al, 2021 ; Pradit et al, 2022a ). Microplastics (MPs) are plastic debris defined as particles less than 5 mm ( NOAA, 2009 ) and are classified as marine waste.…”

Background Microplastics (MPs) are pollutants in rivers and marine environments. Rivers can be sources and sinks of MPs that enter the biota. Previous studies focusing on freshwater species are quite limited, especially for gastropods. Freshwater gastropods are essential to aquatic ecosystems because they are food to other aquatic animals, such as fish, shrimp, and crabs. They are a crucial link in the food chain between water resources and human food. Therefore, this study aimed to investigate MP accumulation in freshwater gastropods, commonly known as snails (Filopaludina sumatrensis speciosa and Pomacea canaliculata), in a river flowing into a shallow coastal lagoon. Method In this study, snail tissue samples were digested with 30% hydrogen peroxide. The mixture was heated at 60 °C for 24 h. MP particles were identified, counted, and characterized (shape, size, and color) by visual identification under a stereomicroscope. Furthermore, polymer-type identification was performed using Fourier transform infrared spectroscopy (FTIR). Analysis of variance (ANOVA) was applied for the statistical analysis. Results The MPs found were as follows: 4.76 particles/individual were found in F. sumatrensis speciosa upstream, 5.20 particles/individual were found in F. sumatrensis speciosa downstream, 7.28 particles/individual were found in P. canaliculata upstream, and 4.00 particles/individual were found in P. canaliculata downstream. It was found in the two-way ANOVA that the accumulation of MPs in gastropods was affected by species and study sites (upstream and downstream). There was a significant difference in the amount of MPs in P. canaliculata between upstream and downstream sites (p = 0.003). Fibers were the most common MPs in both species. Moreover, P. canaliculata upstream had the most significant amount of MPs. The smallest amount of MPs was recorded for P. canaliculata downstream, but there was great diversity in shape, size, and polymer type. MPs sized 500 μm–1 mm were the most common in both species. Fourier transform infrared spectroscopy revealed six polymers: poly (ethylene terephthalate), polypropylene, rayon, polyethyleneimine, polyamine, and poly (propylene: ethylene). The occurrence of MPs in gastropods is alarming for food security in Thailand. The results of this study can be used to support baseline data on MP accumulation among freshwater gastropods.

“…Plastics are used in the pharmaceutical industry, agricultural industries, automobiles, storage, clothing, transportation, packaging, etc. This increases the production of plastics each day [2]. Around 60% plastic packaging is used for food and beverage and rest is used for other purposes like cosmetics, medicines, etc.…”

In today's world, packaging plays a crucial role in enhancing, enclosing, and shielding the materials that are used from procurement to handling and storage, processing, manufacturing and finally to the consumer. Packaging shields a product's contents from contamination, spoiling and makes it simple to store and transfer anywhere. Man-made plastic breaks down into little particles as a result of numerous external pressures. The degradation of plastics produce nano or microplastic. Health issues arise when microplastics (MPs) leak from plastic food packaging and are consumed by people. Though plastic packaging is abundant, consumers from developing nation are not aware of the risk associated with plastic food packaging. The purpose of this study is to demonstrate occurrence of microplastics in plastic food packaging and highlight the risks involved in consumption of microplastics. In this research, the migration of microplastics from different plastic containers were noted in accordance to the Bureau of Indian Standards IS - 9845-1998. The IS 9845: 1998 method was utilized in this investigation to determine the overall migration of various plastics used to package mineral water and beverages. Distilled water and 3% acetic acid (w/v) were utilized as food simulators for the analysis. The migration of microplastics in mineral water were found to range from 0.38 ppm to 0.54 ppm while in case of non-alcoholic beverages overall migration ranged from 0.29 to 75.75 ppm. Among the 12 samples of non-alcoholic beverages, one sample exceeded the maximum limit of microplastics as specified by WHO standard.microplastics
