Danger Dust

People may be at increased risk from cancer, diabetes, cardiovascular disease, and chronic lung disease—as rising global levels of micro- and nanoplastics (MnPs) are absorbed into the human body, a new study reveals.

The researchers highlight that the relationship between MnPs and NCDs resembles those of other particles, including natural sources such as pollen or human-made pollutants like diesel exhaust, and MnPs, and engineered nanomaterials, all acting in a similar biological manner.

The body treats these as foreign entities triggering the same protective mechanisms—presenting a risk of bodily defenses becoming overwhelmed and boosting the frequency and severity of NCDs.

Humans are exposed to MnPs in outdoor and indoor environments through food stuffs, drinks consumption, air and many other sources including cosmetics and human care products.

MnPs have been found in fish, salt, beer, and plastic bottled drinks or air, where they are released from synthetic clothing materials, plastic fabric bedding during sleep, plastic carpet or furniture. Other sources can include fertilizer, soil, irrigation, and uptake into food crops or produce.
