Microplastics (MPs) are developing as persistent pollutants that are causing significant concern in terms of environmental health. A microplastic is a particle of plastic that is less than 5 mm in diameter, which has penetrated and harmed the environment. MPs have been the subject of numerous analyses, including several adverse assessments, however, most of these studies have focused on their presence in coastal environments. The current state of knowledge regarding the characteristics, occurrences, and potential impact of MPs in the terrestrial ecosystem is incomplete. The goal of this study is to undertake a thorough review of existing knowledge and scientific publications on MP occurrences in the environment, their fate and mobility, and their consequences, as well as to explore such discoveries. MPs have been elaborately discussed in this review in terms of their occurrences, features, and origins in the oceans, freshwater, sediments, soils, and the atmosphere, along with the data obtained from experiments and models on the fate and mobility of MPs in the environment. This paper also includes research data on the environmental toxicity, bioavailability, and bioaccumulation of MPs.
