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.
The loss of these chemicals causes the plastic to revert to a brittle state, often shrinking or distorting in shape. The migrating chemicals may cause other nearby objects to deform or otherwise degrade. In addition, many plasticizers, such as phthalates or bisphenol A (BPA) may be toxic, hormone disruptors, or carcinogenic in their biological ...
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.

If your water tests positive for PFAS, exposure to the chemicals can be avoided by using a carbon or reverse osmosis filtration system. “Whenever possible, avoid drinking unfiltered tap water ...
One liter of water — the equivalent of two standard-size bottled waters — contained an average of 240,000 plastic particles from seven types of plastics, of which 90% were identified as ...
The biggest quantity of stabilizers is used for polyvinyl chloride (PVC), as the production and processing of this type of plastic would not be possible without stabilizing chemicals. [1] Common polymer degradation processes include oxidation , UV-damage , thermal degradation , ozonolysis , combinations thereof such as photo-oxidation , as well ...
The researchers bought 112 plastic or glass bottled water samples – 89 still and the rest sparkling – from local shops and online supermarkets across the UK and China, including 87 brands with ...
Environmental Stress Cracking (ESC) is one of the most common causes of unexpected brittle failure of thermoplastic (especially amorphous) polymers known at present. According to ASTM D883, stress cracking is defined as "an external or internal crack in a plastic caused by tensile stresses less than its short-term mechanical strength".
