Impact of aquatic microplastics and nanoplastics pollution on ecological systems and sustainable remediation strategies of biodegradation and photodegradation

The extreme degree of microplastics contamination and its negative impact on ecosystems has become a serious and emerging global concern. Microplastics are mainly generated from products that are used primarily in our everyday lives and are also generated from the fragmentation of larger plastic wastes. It easily penetrates the food chain and, when ingested by aquatic animals or humans, can pose serious health problems. Recently, several technologies have been developed to control the unrestricted spread of microplastics and possibly eradicate them; however, still under investigation. In this review, we have illustrated the types of microplastics, their harmful effect on living things, and the progress to degrade them to protect the environment and life on earth. Several promising and eco-friendly technologies including microbial and enzymatic approaches are enticing to eliminate the microplastics. Also, the photodegradation of microplastics contaminations appeals as a more fascinating approach. The metal oxide-assisted photodegradation of microplastics has also been taken into account. This work presented an impact on the comprehensive research for the effective degradation of different microplastic compositions as well as emerging green approaches for a sustainable environment and a healthier life.
