Toxic metals can bioaccumulate in the body and in the food chain. [5] Therefore, a common characteristic of toxic metals is the chronic nature of their toxicity. This is particularly notable with radioactive heavy metals such as radium , which imitates calcium to the point of being incorporated into human bone, although similar health ...
The ratio of crosslinking to chain scission is also affected by temperature, environment, presence of oxygen versus inert gases, radiation source (changing the penetration depth), and whether the polymer has been dissolved in an aqueous solution. [15] Crosslinking and chain scission have diverging effects on mechanical properties.
A 25-foot (7.6 m) wall of coal fly ash from the release of 5.4 million cubic yards ash slurry into the Emory River, Tennessee, in 2008. [1] The river water was contaminated with toxic metals including arsenic, copper, barium, cadmium, chromium, lead, mercury, nickel, and thallium. [2]

The U.S. Food and Drug Administration is for the first time setting guidelines for levels of lead in processed baby foods such as jarred fruits and vegetables.
A food safety hazard is any biological, chemical, or physical property that may cause a food to be unsafe for human consumption. Identify critical control points A critical control point (CCP) is a point, step, or procedure in a food manufacturing process at which control can be applied and, as a result, a food safety hazard can be prevented ...
Hazard statements form part of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). They are intended to form a set of standardized phrases about the hazards of chemical substances and mixtures that can be translated into different languages.
