Microplastics are widespread over the globe

Microplastics are widespread over the globe, be it in the ocean, lakes, rivers, freshwaters, even in the food that you intake, available literatures reported about the use of plastic and the release suggested that a primary and secondary microplastics are most likely found widespread across freshwater and terrestrial environment. (Jeong et al., 2016; Lee et al., 2013) Both primary and secondary microplastics that enters the environment continue to break into small particles, and this smaller particles are bound to pose a much greater risk to health. Due to the increased likelihood of uptake and increased of surface area for the interaction with the chemicals and a great number of particles per unit of bulk mass.
Horton et al (2018) stated that microplastics acts as both direct hazard (particulate) and indirect hazard (chemical) unravelling ecological effects that calls for the application of approaches for mixture of toxicity that may be beneficial for the analysis of combined plastic-chemical effects.
Over the decade there has been an increased scientific interest that the knowledge base of microplastic has expanded. According to Lindeque et al. (2011) the highest abundance of microplastics is associated along the coastlines and mid-ocean gyres but these microplastics are mostly elusive and are hypothesized that microplastics sink by biofueling, fragments into a smaller polymer or ingested by marine biotas. In testing such hypothesis is inhibited by the components of the sampling from the oceans depths and the complication of routinely sampling and detecting a smaller-sized fragments of microplastics. Microplastics are dormant hazards for the marine organisms and their quantity is increasing day-by-day and such is the reason behind several abnormalities in the health and behavior of fishes.
Microplastics are ingested by fishes whether intentional or not and are accumulated in the gastrointestinal tract and stomach of the biota. Raza (2018) Plastics are dumped in aquatic bodies across the world and these plastics breakdown and the results causes these fragments to break into smaller pieces which is dangerou to aquatic life. Some microplastics have various ecotoxicological effects on fishes which causes behavioral change. Some things should also be considered; rules to regulate and counter the microplastics in aquatic environments, evaluation of toxic effects and biomagnifications of microplastics through food chains, monitoring of production of personal care products that contains microplastics, establish techniques to detect and filter microplastics & etc.
A new method for the processing and sampling of wastewater microplastics was developed and applied to three wastewater treatment plants to utilize different kinds of treatment processes. Fibres are the dominant kind of microplastic that are detected in wastewater effluent samples and are not always removed completely after the advanced treatment process. The microplastic beads present in all personal care products recieved a lot of notice and attention. The results suggests that synthetic fibres from any type of clothing may be a larger concern that needs immediate attention.
As of the current generation, the world’s wasterwater treatment plant system remains understudied mainly for the emerging contaminant load. It is required to have more data and informatiom on various treatments and analysis of the impacts of the contaminants on the efficacy of treatment plants operation (Blair et al. 2017). Wastewater treatment plants are significant pathways for the pollution of the environment (Minteng et al. 2017; Carr et al. 2016; Michielssen et al. 2016; Ziajahromi et al. 2017). Wastewater treatment plants can also generate microplastics of various sizes and this issue requires an investigation concerning trophic transfer. The diversity of nature with mixed contaminats in wastewater treatment plants impels researchers to anaylize the interaction between microplastics and the toxic pollutants in the water.
