“…In the zooplankton, Daphnia magna reduction in body size and alteration in reproduction and malformations observed raise concern on the entry of microplastics into food webs (Besseling et al, 2014). Daphnia pulex exposed to polystyrene for 21 d slowed the growth rate, reproductive ability, and reproductive pattern and changed the sex ratio (Zhang et al, 2020). Microplastic contamination in the juvenile Daphnia revealed modifications in the body length, width, and tail spine length whereas adult showed alterations in the expression of stressrelated genes such as HSP60, HSP70, and GST, as well as the genes involved in body function and body composition namely, Sarco/ endoplasmic reticulum Ca 2+ -ATPase gene (Imhof et al, 2017).…”

The accumulation of plastic products in the terrestrial and aquatic environment is one of the major concerns in recent years. The quality of the ecosystem is affected globally due to the large production, ubiquitous usage, and poor plastic waste disposal. Plastic debris is categorized based on its size as macroplastics, mesoplastics, microplastics, and nanoplastics, respectively. Microplastics are the emerging contaminant that occurs in varying shapes like tiny beads, spheres, films, fragments, fibres, and filaments. The use of microplastics in cosmetics and abrasion from large plastic items including textile fibres and tyres are suspected to contaminate the environment when it reaches the aquatic ecosystem. Indian coastal waters are polluted by microplastics owing to industrialization, overpopulation, tourist and maritime activities. Many species of fishes, reptiles, birds, and mammals are directly threatened by entanglement or ingestion, and some marine mammals consume a large amount of microplastic debris by raptorial feeding thereby leads to trophic transfer. Humans are considered as the most exposed organisms than other vertebrates as they occupy at the top of the food chain. Certain government legislations have been put forth to ban some products that are considered as the major contributor to plastic debris. Recently, the use of bioplastics is increased all over the world to replace microplastics in industrial and commercial products. However, there is little awareness of the microplastic pollutants among the public, thus the main motive of this review is to provide public awareness and responsibility to limit the use of plastics that adversely damage our environment

“…Interestingly, nanoplastic toxicity is differential as it relates to the health and anaerobic digestion activity of microbial communities [29]. Genotoxicity and modified genetic expression patterns has been identified after exposure in brine shrimp and zooplankton, leading to the hypothesis that nanoplastics may be mutagenic in high doses [28,30]. Co-incubation of polystyrene and polycarbonate nanoparticles promoted upregulation of stress responses within the innate immune system of fish [31].…”

Undoubtedly, plastics have changed human existence. These pervasive products are used in nearly every field to include technological, biomedical, and domestic applications. Post-consumer plastic waste disposal leading to plastic pollution in landfills, waterways, and oceans represents a worldwide environmental challenge. Accumulation and continued material fragmentation from micro- to nanoplastics has identified concerns pertaining to environmental and human exposures and toxicity. While many studies have focused on particle fate and identification, the toxicological considerations must focus on the biological relevance of particle deposition within a particular organism, compartment, organ, and tissue. Further, concerns exist regarding the physical and chemical properties of the plastic particles during their production and/or degradation. In this mini-review we will discuss (1) particle characterization and assessment, (2) environmental concerns, and (3) human toxicity.

“…17,18,19,20 The toxicity of these synthetic polymeric nanoparticles has been extensively investigated on cells and marine organisms at different trophic levels, evidencing several biological dysfunctions. 21,22,23,24,25,26,10 In addition, nanoplastics could be even more dangerous than their micrometric counterpart because, due to nanometric size, they are thought to be able to penetrate tissues and biological barriers. 27,28 However, despite this bulk of information, several knowledge gaps still exist about the behavior and characteristics of naturally-occurring nanoplastics.…”

Given the complexity of separating nanoplastics from environmental samples, studies have usually been conducted using synthetic polystyrene nanobeads. By mechanical fragmentation in cryogenic conditions of daily-life plastic items, we produced “true-to-life” nanoplastics (T2LNPs), that promises to give a true insight into the interaction with biological systems. T2LNPs have been fully characterized by Fourier transform Infrared spectroscopy and by Atomic Force Microscopy. They result in populations of spheroidal nanoparticles with a broad multimodal size distribution. The mandatory need for a representative sample to evaluate the potential effects of nanoparticles on human health and the environment is demonstrated by the different protein corona identified on T2LNPs and synthetic polystyrene nanobeads upon incubation with human plasma.
