Woodruff, who has studied the effect of some chemicals found in plastics on human health, reproduction, and development for two decades, first started looking into microplastics in 2021.
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 NIOSH Nanomaterial Exposure Assessment Technique (NEAT 2.0) is a sampling strategy to determine exposure potential for engineered nanomaterials. It includes filter-based and area samples, as well as a comprehensive assessment of emissions at processes and job tasks to better understand peak emission periods.
Based on the microbes identified, only 4.07% were members of genera that could degrade the plastics found in the garbage patch. Along with that, the bacteria were only known to degrade PE and not PP. The researchers concluded that more investigation is needed to find a natural way to combat the accumulation of plastic in the garbage patch.
However, as Food & Wine previously reported, while the effect of microplastics on humans is an ongoing topic of research, several studies have shown that microplastics have the potential to affect ...
This affects soil biological activity, biodiversity and plant health. Microplastics in the soil alter a plant's growth. It decreases seedling germination, affects the number of leaves, stem diameter and chlorophyll content in these plants. [102] Microplastics in the soil are a risk not only to soil biodiversity but also food safety and human ...
The study found that while there wasn't a significant difference between land and sea proteins, there were significantly more microplastics found in highly processed products like plant-based ...
The United States Environmental Protection Agency defines NOAEL as 'an exposure level at which there are no statistically or biologically significant increases in the frequency or severity of adverse effects between the exposed population and its appropriate control; some effects may be produced at this level, but they are not considered as adverse, or as precursors to adverse effects.
