Some research has been conducted on the study of gas emissions from the spontaneous combustion of coal and their impact on the environment [53,54,55,56]. Many gases formed as a result of combustion are formed during conventional coal mining, but the concentrations of these gases vary depending on environmental changes, so there is no unified approach to assessing

CO is a colorless and odorless gas that is generated in the urban environment primarily by the incomplete combustion of fossil fuels in motor vehicles. In New York City, more than 80 percent of CO emissions are from motor vehicles. Prolonged exposure to high levels of CO can cause headaches, drowsiness, loss of equilibrium, or heart disease.
