The presence of plastic in the environment hurt ecosystems and human health and pose a threat to food safety. [91] Chlorinated plastic can release harmful chemicals into the surrounding soil, which can then seep into groundwater or other surrounding water sources and also the ecosystem of the world. [92]
The Stockholm Convention on Persistent Organic Pollutants is a global treaty to protect human health and the environment from chemicals that remain intact in the environment for long periods, become widely distributed geographically, accumulate in the fatty tissue of humans and wildlife, and have harmful impacts on human health or on the ...
A big reason is the lack of capacity for recycling various plastics. Industry argues much more than 5 percent is getting recycled and that there is room for more. Correction: An earlier version of ...
Humans are exposed to toxic chemicals and microplastics at all stages in the plastics life cycle. The effects of microplastics on human health are a growing concern and an actively increasing area of research. Tiny particles known as microplastics (MPs), have been found in various environmental and biological matrices, including air, water ...
Plastic degradation in marine bacteria describes when certain pelagic bacteria break down polymers and use them as a primary source of carbon for energy. Polymers such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) are incredibly useful for their durability and relatively low cost of production, however it is their persistence and difficulty to be properly ...
By using data on surface plastic concentration (pieces of plastic per km 2) from 1972 to 1985 (n=60) and 2002–2012 (n=457) within the same plastic accumulation zone, the study found the mean plastic concentration increase between the two sets of data, including a 10-fold increase of 18,160 to 189,800 pieces of plastic per km 2.
Bisphenol A (BPA) is an environmental contaminant that disrupts the ecosystem, with the most profound effects observed in vertebrates. [116] BPA infiltrates the environment by running off of landfills so because of this, it is mostly found in water. [116] Aquatic vertebrates are thus the most affected by this form of pollution. [112]
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.
