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,

However, the EWG regarded CSIA as moving in the right direction because the EPA would have gained more authority to review existing chemicals and order companies to provide any relevant safety data about a specific chemical in question. Earthjustice further called for the final result of TSCA reform to be one that adequately protected workers continually exposed to hazardous chemicals, vulnerable populations, and communities most at risk because of high exposure to toxic chemicals. The CSIA would have required states to co-enforce any requirements laid out by the EPA, i.e. to have funding and man-power to enforce all
