Mercury (element) elevated over outdoor concentrations, at a range of 0.0065 – 0.523 μg/m. The average was 0.069 μg/m. Mercury also enters into the environment through the improper disposal (e.g., land filling, incineration) of certain products. Products containing mercury include: auto parts, batteries, fluorescent bulbs, medical products, thermometers, and thermostats. Due to health concerns (see below), toxics use reduction efforts are cutting back or eliminating mercury in such products. For example, the amount of mercury sold in thermostats in the United States decreased from 14.5 tons in 2004 to 3.9 tons in 2007. Most thermometers now use pigmented alcohol instead of mercury,
Toxic injury products, pharmaceuticals and industrial products. Many commonly found natural substances may be toxic. They can be found in our air, water or food supply. The top ten most common environmental toxins are: Avoiding direct exposure to toxins will reduce the risk of toxic injury. For safety reasons, wear personal protective equipment when working near environmental or chemical toxins. Many countries have guides classifying dangerous goods and identifying the risks associated with them, such as Canada's Workplace Hazardous Materials Information System. These guides have been developed to ensure worker safety when handling dangerous chemical toxins. It is also important to maintain
