Reproductive toxicity and transgenerational effects of co-exposure to polystyrene microplastics and arsenic in zebrafish.

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.

Rapid, on-site quantitative determination of mycotoxins in grains using a multiple time-resolved fluorescent microsphere immunochromatographic test strip.

The label probe plays a crucial role in enhancing the sensitivity of lateral flow immunoassays. However, conventional fluorescent microspheres (FMs) have limitations due to their short fluorescence lifetime, susceptibility to background fluorescence interference, and inability to facilitate multi-component detection. In this study, carboxylate-modified Eu(III)-chelate-doped polystyrene nanobeads were employed as label probes to construct a multiple time-resolved fluorescent microsphere-based immunochromatographic test strip (TRFM-ICTS).

Enhanced reproductive toxicity of photodegraded polylactic acid microplastics in zebrafish.

Microplastics are widely used due to their numerous advantages. However, they can have detrimental effects on marine ecosystems. When microplastics enter the ocean, they can be absorbed by marine organisms, leading to toxic effects.

The combined toxic effects of polystyrene microplastics and different forms of arsenic on the zebrafish embryos (Danio rerio).

Microplastics have been widely studied for their ability to adsorb heavy metals. In the natural environment, arsenic exists in different forms and its toxicity depends mainly on its form and concentration. However, different forms of arsenic combined with microplastics have yet to be explored for their biological hazards.
