Landfill gases are formed when buried wastes decompose due to microorganisms or volatizes as the waste changes from a liquid or solid to a vapor. These microbial and chemical processes create gases that can often be detected in areas surrounding a landfill.
Landfill gases at high concentrations may cause people to experience eye irritation, headaches, nausea, and soreness of the nose and throat. People with respiratory ailments such as asthma are especially sensitive to these effects.
