“…summarizes the algal species that have been used to remove microplastics from the aquatic environment and highlights the mechanism of microplastics biodegradation. 56 It is generally believed that after entering the human body, microplastics will be excreted out through the gastrointestinal tract and biliary tract. However, researchers detect the existence of microplastics in human blood.…”

Microplastics are ubiquitous in the global environment. As a typical emerging pollutant, its potential health hazards have been widely concerning. In this brief paper, we introduce the source, identification, toxicity, and health hazard of microplastics in the human. The literature review shows that microplastics are frequently detected in environmental and human samples. Humans are potentially exposed to microplastics through oral intake, inhalation, and skin contact. We summarize the toxic effects of microplastics in experimental models like cells, organoids, and animals. These effects consist of oxidative stress, DNA damage, organ dysfunction, metabolic disorder, immune response, neurotoxicity, as well as reproductive and developmental toxicity. In addition, the epidemiological evidence suggests that a variety of chronic diseases may be related to microplastics exposure. Finally, we put forward the gaps in toxicity research of microplastics and their future development directions. This review will be helpful to the understanding of the exposure risk and potential health hazards of microplastics.

“…Physical abrasion also generates secondary microplastics. Moreover, biological agents like bacteria, fungi and algae are known to produce a plethora of enzymes which play a crucial role in microplastic degradation (Chia et al 2020 ; John et al 2021 ; Othman et al 2021 ; Chen et al 2022 ; Manzi et al 2022 ; Miri et al 2022 ; Zhu et al 2022 ).…”

“…Microalgae and their enzymes and toxins can be effectively used in the biological breakdown of polymeric material (Moog et al 2019 ; Chia et al 2020 ; Manzi et al 2022 ). The main advantage is that they do not require a rich carbon source for growth when compared to the bacterial system and are adapted to a wide variety of habitats where most of the microplastics occur (Yan et al 2016 ).…”

Microplastics pollution is major threat to ecosystems and is impacting abiotic and biotic components. Microplastics are diverse and highly complex contaminants that transport other contaminants and microbes. Current methods to remove microplastics include biodegradation, incineration, landfilling, and recycling. Here we review microplastics with focus on sources, toxicity, and biodegradation. We discuss the role of algae, fungi, bacteria in the biodegradation, and we present biotechnological methods to enhance degradation, e.g., gene editing tools and bioinformatics.

“…revealed that though the rate of accumulation of fluoranthene is not influenced by MPs, they modulate the toxicity of fluoranthene's highest levels of antioxidant activities and histopathological damage to the mussels (Paul‐Pont et al, 2016). MPs further have a negative impact on marine and freshwater microalgae photosynthesis (Chen et al, 2022; Manzi et al, 2022). They recommended both adsorption and aggregation of MPs on the microalgae outer surface as the most likely toxicity mechanism based on the results of morphological studies and scanning electron microscopy (SEM).…”

Microplastics (MPs) with slow degradation rates carry toxins and pathogens from surroundings, accumulate and pollute the environment. They bio‐accumulate on humans and other lifeforms leading to health concerns, including inflammatory lesions, oxidative stress and increased cancer risk, thus requiring immediate remediation actions. This review summarizes, categorizes and analyses recent findings on MP source, transit and environmental toxicity and explores their microbe‐mediated breakdown. Various micro‐organisms such as fungi, bacteria, algae and protists interact with and build biofilm on MP surfaces and alter their surface morphology for their degradation. Pure strains and microbial consortia have been successfully able to degrade MPs. Extracellular enzymes are produced by these micro‐organisms that convert the complex recalcitrant polymeric structure of MP to simpler forms. Further, knowledge of factors associated with MP degradation along with the development of genetic tools enhances the rate of microbial degradation with consortium having an advantage over single bacterium‐mediated MP transformation, which has been discussed.
