Fossil fuel percent of [its] weighted emissions in 1998. Combustion of fossil fuels also produces other air pollutants, such as nitrogen oxides, sulfur dioxide, volatile organic compounds and heavy metals. According to Environment Canada: "The electricity sector is unique among industrial sectors in its very large contribution to emissions associated with nearly all air issues. Electricity generation produces a large share of Canadian nitrogen oxides and sulphur dioxide emissions, which contribute to smog and acid rain and the formation of fine particulate matter. It is the largest uncontrolled industrial source of mercury emissions in Canada. Fossil fuel-fired electric power plants also emit
Environmental health ethics unsafe food, eating in overlarge quantities, are well documented yet in all societies there is no legislation against over-consumption. Ethical properties of utilitarianism and social justice conflict with humanity's freedom of choice in the determining of access to healthy, safe food.

From an ethical standpoint many things about pollutants can be studied, like questions of disposal, storage, recycling, and responsibility. A few examples of air pollutants include particulate matter, sulfur dioxide, nitrogen oxides, carbon oxides, chlorofluorocarbons, and heavy metals (e.g. mercury). Perhaps
