Informal landfill contributes to the pollution of microplastics in the surrounding environment.

Environmental Pollution, 2021
A large amount of plastic waste is generated yearly worldwide, and landfills are commonly used for the disposal of plastic waste. However, burying in landfill does not get rid of the plastic waste but leave the problem to the future.

PPE: producing polluted environment

BMJ, 2021
It is undeniable that pollution is having a catastrophic effect on our planet. Recently, the environmental impact of personal protective equipment (PPE) has been studied.12 Wise says that in the first three months of the covid-19 pandemic, trusts used three million masks compared …

Microplastics pollution in the marine environment: A review of sources, impacts and mitigation.

Marine Pollution Bulletin
Over the past few years, microplastics (MPs) pollution in the marine environment has emerged as a significant environmental concern. Poor management practices lead to millions of tons of plastic waste entering oceans annually, primarily from land-based ...

Are we underestimating the sources of microplastic pollution in terrestrial environment?

Journal of Hazardous Materials, 2020
Microplastics (MPs, plastic particles < 5 mm) are an ever-increasing global issue due to their widespread occurrence in the environment and negative effects on organisms. Currently, more than 96 % of MPs studies are related to marine systems.

A control problem in a polluted environment

Mathematical Biosciences, 1996
Due to the importance of remediating polluted environments, many mathematical models have been developed to describe population-toxicant interactions. This article considers the situation where the amount of pollution in the environment is restricted to lie below a certain value M.

Permanence of populations in a polluted environment

Mathematical Biosciences, 1994
Studies of several population-toxicant models are discussed. Under the hypothesis that the exogenous input of toxicant into the environment is periodic in time, the conditions for permanence of populations are obtained.

Trace Metal Pollution in the Environment

Journal of the Air Pollution Control Association, 1973
Trace metals introduced to the environment from fuel combustion, incineration, and industrial emission sources are causing increasing concern to air pollution researchers. Several metals in urban air, including lead and vanadium, are associated with particles in the predominantly submicrometer diameter range thereby presenting an inhalation threat ...

Microplastics in the marine environment: Current trends in environmental pollution and mechanisms of toxicological profile.

Environmental Toxicology and Pharmacology, 2019
The global plastics production has increased from 1.5 million tons in the 1950s to 335 million tons in 2016, with plastics discharged into virtually all components of the environment.
