Microplastic pollution is a global crisis. This requires a better understanding of microplastic abundance, distribution, and accumulation to prevent potential risks in the future. However, it is very difficult to accurately identify all polymers of microplastics due to the limits of present detection technologies, which might result in overestimation and underestimation of microplastic pollution. Moreover, it also doesn't meet the growing demand for regular monitoring. Herein, we propose an alternative approach to regularly monitoring microplastics in all environmental mediums. The results could meet the urgent need for understanding the spatiotemporal pattern of microplastic pollution. Environmental policy-makers can use it to monitor microplastic pollutants and then rapidly evaluate the environmental level of microplastic pollution.

When microplastics (MPs) enter water bodies, they undergo various transport processes, including sedimentation, which can be influenced by factors such as particle size, density, and interactions with other particles. Surface waters contain suspended natural particles (e.g.

The issue of plastic pollutants has become a growing concern. Both microplastics (MPs) (particle size < 5 mm) and nanoplastics (NPs) (particle size < 1 µm) can cause DNA damage, cytotoxicity, and oxidative stress in various organisms. The primary known impacts of microplastic/nanoplastic are observed in the liver and respiratory system, leading to hepatotoxicity and chronic obstructive pulmonary disease.

Microplastics (MPs) are ubiquitous environmental pollutants that have garnered significant attention due to their small particle size, resistance to degradation and large specific surface area, which makes it easy to adsorb various pollutants, particularly heavy metals. Arsenic (As), a common metal poisons, poses significant risks due to its widespread industrial use. When MPs and As co-exist in the environment, they can exert combined toxic effects on organisms, affecting various systems, including the nervous system.

Microplastic pollution in marine environments poses significant environmental risks due to its widespread presence. Traditional micro-imaging measurement of microplastics often rely on post-cruise laboratory analyses. In this study, we explored the feasibility of onboard microplastic measurement using Raman spectroscopy, with a focus on polyethylene (PE).

Microplastics (MPs), as the crucial environmental pollutants, can be easily transported into the human body and accumulate in the liver. However, current studies mainly focus on acute exposure to MPs, investigations on long-term interactions with MPs alone remain limited. Thereby, we examined noxious properties of MPs and selected the most common polystyrene (PS) MPs as the research object, including unmodified PS MPs (PS-MPs) and positive-charged PS MPs (PS-NH) at 10 mg/L employing oral drinking water methods in mice for six consecutive months in vivo.
