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.
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, food, and human tissues.
New research finds a link between eating out of plastic takeout containers and heart disease. The study adds to growing evidence that plastic chemicals may negatively influence your health.
A second study suggested carcinogenic effects were unlikely and that the primary risk would be associated with developmental effects due to exposure in pregnancy and neonates. [108] Two businessmen who knowingly sold the contaminated feed ingredient received two-year suspended sentences for their role in the crisis.
Lead poisoning, also known as plumbism and saturnism, is a type of metal poisoning caused by lead in the body. [2] Symptoms may include abdominal pain, constipation, headaches, irritability, memory problems, infertility, numbness and tingling in the hands and feet. [1]
Not all non-stick pans use Teflon; other non-stick coatings have become available. For example, a mixture of titanium and ceramic can be sandblasted onto the pan surface, and then fired at 2,000 °C (3,630 °F) to produce a non-stick ceramic coating. [19] Ceramic nonstick pans use a finish of silica (silicon dioxide) to prevent sticking.
Aluminosilicates are commonly used in dental prostheses, pure or in ceramic-polymer composites. The ceramic-polymer composites are a potential way to fill cavities, replacing amalgams suspected to have toxic effects. The aluminosilicates also have a glassy structure. Unlike artificial teeth in resin, the colour of tooth ceramic remains stable.
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
