Pollution from microplastics has recently become a prevalent threat to the ecosystem. Microplastics with a dimension less than or equal to 5 mm are smaller. There are many ways that microplastics can reach the atmosphere. By various mechanisms, the breakdown of macro plastics will happen. Chemical degradation, tire abrasion, is the most common forms of degradation. Microplastics (MPs) pollution in the coastal and marine ecosystem is currently a global problem. Transferring MPs from land to sea and allowing them to enter the food chain has a direct negative impact on marine life and human health. The combined toxicity effects of MicroPlastics (MPs) and other contaminants in marine environments, as well as their toxicity effects and mechanisms based on a variety of environmentally important test organisms, were also covered in this study.

Abstract The objective of this paper is to present a thorough analysis of the toxicity of microplastics (MPs) and nanoplastics (NPs) with the heavy metal cadmium (Cd). These components were studied separately and combined to determine how these environmental toxins affect Microcystis aeruginosa (M. aeruginosa) in fresh water. The combined toxicity of MPs or NPs and Cd to M. aeruginosa showed an aggressive and negative effect after 96 h of exposure. Due to the higher adsorption ability of NPs, the accumulation of Cd inside cells with NPs was lower than that found inside the cells with MPs. But the difference in toxicity between the MPs and NPs was not significant. Meanwhile, the more produce of the extracellular polymeric substance (EPS) in the presence of NPs, the more complex effect of EPS bonded to heavy metals, which reduce the toxic effect on the algal cells. Notably, the production of microcystin-LR (MC-LR) under different treatments has demonstrated that the presence of combined MPs/NPs with Cd can potentially raise some of the toxin risks harming the aquatic environment. Our findings highlight the great potential ecological risks of the combined Cd and MPs/NPs in the aquatic system.
