The increase in plastic and microplastic pollution in soils can cause adverse impacts on plants and microorganisms in the soil, which can in turn affect soil fertility. Microplastics affect soil ecosystems that are important for plant growth.
A substantial portion of microplastics are expected to end up in the world's soil, yet very little research has been conducted on microplastics in soil outside of aquatic environments. [158] In wetland environments microplastic concentrations have been found to exhibit a negative correlation with vegetation cover and stem density. [149]
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle Microplastics effects on human health are of growing concern and an area of research. The tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water, food, and human tissues.
Plastic pollution is widely recognized as a critical global issue. It continues to overwhelm waste management systems, flooding plastic into our oceans, soil, air, and food chains, and raises ...
However, as plastic is broken down into smaller pieces and eventually microplastics, there is a higher likelihood that it will be consumed by plankton and enter into the food chain. [58] As plankton are eaten by larger organisms, the plastic may eventually cause there to be bioaccumulation in fish and other marine species eaten by humans. [58]
[8] [9] Primary microplastics make up between 15% and 31% of the growing amount of marine microplastic pollution, which is related to the corporative expansion of large-scale plastic production. [9] Like microbeads , preproduction plastic pellets can be released directly into the environment as a form of primary microplastic pollution. [ 9 ]
Tiny plastic particles have been found throughout the human body, but researchers say they’re just starting to understand the impact. When Jaime Ross, PhD, a neuroscientist and assistant ...
As global plastic production has ramped up in the last 20 years, so too has the concentration of these shredded, fossil fuel-derived polymers in human tissue samples.
