An old sewer gas chimney in Stonehouse, Plymouth, England, built in the 1880s to disperse sewer gas above residents. Sewer gas is a complex, generally obnoxious smelling mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage.
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
Gas appliances are designed to vent CO outdoors, but if there’s a malfunction, they can leak it indoors and cause carbon monoxide poisoning. Breathing in a lot of CO can make you pass out, or ...
Prolonged exposure to relatively low levels of nitrogen (II) oxide may cause persistent headaches and nausea. [18] Like chlorine gas poisoning, symptoms usually resolve themselves upon removal from further nitrogen dioxide exposure, unless there had been an episode of severe acute poisoning. [19] Treatment and management vary with symptoms.

[1] [2] [3] Chronic exposure to relatively low levels of chlorine gas may cause pulmonary problems like acute wheezing attacks, chronic cough with phlegm, and asthma. [2]
Products that are packaged in aerosol cans contain a chemical known as propellant gas. [5] Almost always, this propellant gas is called chlorofluorocarbons (CFCs). [5] CFCs have been proven to damage the ozone layer and caused the ozone hole. Thus, in 1996, CFCs were banned directly as a result of the detrimental environmental impacts. [6]
