Answer 1

When solid waste is placed in landfills it breaks down—mostly under oxygen-poor (anaerobic) conditions—releasing landfill gas composed mainly of methane and carbon dioxide, plus volatile organic compounds (VOCs) and odorous gases like hydrogen sulfide; methane is a potent greenhouse gas and VOCs can react with NOx to form ground‑level ozone, while odors and toxic VOCs directly degrade local air quality. Inadequate covering, poor gas collection, or migration can allow these gases to vent to the atmosphere, and open burning or landfill fires (intentional or accidental) produce smoke, fine particulate matter, carbon monoxide, polycyclic aromatic hydrocarbons and dioxins/furans that are harmful to human health. Vehicle and heavy-equipment traffic, plus tipping and handling of waste, add dust and diesel exhaust (NOx, PM) to the local air shed, and disturbed waste can release biological aerosols. Together these processes make landfills a source of greenhouse gases, smog precursors, toxic pollutants, odor nuisance, and particulate pollution unless gas capture, proper covering, and waste management controls are used.
