We use plastic in many materials in our daily life. We started using plastic in 1950. This is a very short period of time. Plastic wastes are also distributed to wide area in ecosphere. Research continues on the effect of plastic waste. While the effects of macroplastics on the life of aquatic and terrestrial ecosystems can be observed, the effects of microplastics are not fully known. Our aim in this review is to create a general awareness of microplastics and their distribution in the ecosphere, and the possible negative effects of microplastics. It is to make us aware of the possibility that plastic wastes that we use and do not think are eventually come back into our bodies as microplastics

Plastic pollution includes microplastics. The environmental ubiquity of microplastics (< 5 mm) is evident and the leak of microplastics into the environment is projected to increase globally. Microplastics in the environment possess high heterogeneity in polymer composition, particle size, shapes, and surface chemistry, which sometimes result in contradictory toxicological findings. However, much less attention is paid to the color of microplastics, particularly black plastics that are the least recycled and account for a significant proportion of total plastic waste and environmental microplastics. In the present perspective article, based on 50 field-based research articles on microplastics published from 2014 to 2022 and our own research experience, we raised specific environmental concerns about black microplastics and emphasized the challenges posed by black microplastics in multiple aspects. Future prospects were also discussed for better mitigating black microplastics in the context of plastic pollution.

Environmental problems caused by soil contamination can cause changes in the physical, chemical and geotechnical properties of the soil. Research on a suitable method for soil improvement has focused on the use of biological methods for soil improvement and remediation. Microbial calcium carbonate precipitation has been applied to solve many geotechnical problems. In this study, sandy soil was mixed with two conventional hydrocarbon pollutants and classic soil mechanics tests (compaction, direct shear, uniaxial and permeability tests) were implemented. The use of two bacterial solutions, two-phase injection and bacterial flocculation with injection of cementation solution, produced favorable results. Considering the lower inhibition of gasoline in low dilution, it was possible to improve with both methods. In the case of soil contaminated with motor oil, limitations on the use of microbial calcium carbonate precipitation were improved with the use of bacterial flocculation. The results of this approach were more suitable because the bacteria stabilized between the soil grains. XRD, SEM, EDS and wet chemical analysis were carried out to help confirm and interpret the results.

Abstract Marine microplastic pollution has become one of the global problems due to the adverse effects of microplastics on marine organisms. This study investigated the uptake of (Polystyrene, PS) microplastics by marine rotifers ( Brachionus plicatilis ) under different microplastic concentration, exposure time and type of containers. The results showed that the ingestion of microplastics by rotifers was positively correlated with microplastic concentration. The intake reached maximum (65±5 particles/individuals, 5 mg/L; 28±11 particles/individuals, 3 mg/L) at 24 h, and then decreased over time. Moreover, the intake of microplastics in the plastic well plates was much lower than that in the glass vial. This study demonstrated that the intake of microplastics by rotifers varied with microplastics concentration and exposure time. More importantly, microplastics-related experiments using plastic containers could influence the uptake results. This work provides useful information on the interaction of microplastics with marine organisms.

Microplastics are environmental pollutants that prevail in the oceans, remote islands, and polar regions.Exposure to microplastics presents a major emerging threat to the ecosystems due to their potential adverse effects.Herein, we reviewed the literature to provide an up-to-date synopsis of the current understanding of the sources, compositions, and adverse effects of microplastics in humans and the environment.Most studies on microplastics have focused on developing standardized methods for monitoring the occurrence, distribution, and movement of microplastics in the environment, as well as developing microplastic substitutes; however, although humans are exposed to microplastics via various routes, research on the adverse effects of microplastics in humans remains limited.Little is known about the impact of microplastics on human health and the toxic effects that may vary depending on the type, size, shape, and concentration of microplastics.Therefore, more research is needed to understand the cellular and molecular mechanisms of microplastic toxicity and related pathologies.
