The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
In September 2024, in Food and Water Watch et al. v. United States Environmental Protection Agency, [107] U.S. Federal Judge Edward Chen ruled that water fluoridation posed an, “unreasonable risk of reduced IQ in children…a risk sufficient to require the EPA to engage with a regulatory response…One thing the EPA cannot do, however, in the ...
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.
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer. Contaminated food . The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer). Unlike food-borne pathogens ...
Crystalline silica and lime along with toxic chemicals represent exposure risks to human health and the environment. Fly ash contains crystalline silica which is known to cause lung disease, in particular silicosis, if inhaled. Crystalline silica is listed by the IARC and US National Toxicology Program as a known human carcinogen. [92]
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
Silica: When silica is inhaled from coal ash dust, fetal lung disease or silicosis can develop. [4] Furthermore, chronic exposure of silica can cause lung cancer. [ 4 ] In addition, exposure to silica over a period of time can cause loss of appetite, poor oxygen circulation, breathing complications and fever.
The most common use for Food Grade synthetic magnesium silicate is as an active filter aid for adsorption of color, free fatty acids and other polar compounds from used frying oils. [8] [9] Various national and international regulations allow use of this material as an anti-caking agent in a wide variety of powdered foods. [10] [11] [12] [13]
