Internal combustion engine the atmosphere by the reaction of and volatile organic compounds in the presence of sunlight. Ground-level ozone is harmful to human health and the environment. Though the same chemical substance, ground-level ozone should not be confused with stratospheric ozone, or the ozone layer, which protects the earth from harmful ultraviolet rays. Carbon fuels contain sulfur and impurities that eventually produce sulfur monoxides (SO) and sulfur dioxide (SO) in the exhaust, which promotes acid rain. In the United States, nitrogen oxides, PM, carbon monoxide, sulphur dioxide, and ozone, are regulated as criteria air pollutants under the Clean Air Act to levels
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. Air, water, and solid waste pollution are environmental health issues which can adversely affect people, plants, and animals. 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
