Along with methane, landfills also produce carbon dioxide and water vapor, and trace amounts of oxygen, nitrogen, hydrogen, and non methane organic compounds. These gases can also contribute to climate change and create smog if left uncontrolled.
How do landfills affect the environment and wildlife?
Waste sent to landfill is often laden with chemicals that can affect plant growth in surrounding areas if it leaches into the ground. The chemicals contaminate plants and waters, which are then consumed by animals lower in the food chain.
What are 3 disadvantages of landfills?
There are many negative issues associated with landfill. The three most important problems with landfill are toxins, leachate and greenhouse gases.
How do landfills cause water pollution?
Dumps and landfills are a threat to water supplies when water percolates through waste, picking up a variety of substances such as metals, minerals, organic chemicals, bacteria, viruses, explosives, flammables, and other toxic materials.
Are landfills good for the environment?
Reduce Greenhouse Gas Emissions
As a result, reducing methane emissions from MSW landfills is one of the best ways to achieve a near-term beneficial impact in mitigating global climate change. In addition, methane contributes to background tropospheric ozone levels as an ozone precursor.
What are the bad things about landfills?
The three main problems with landfill are toxins, leachate and greenhouse gases. Organic waste produces bacteria which break the rubbish down. The decaying rubbish produces weak acidic chemicals which combine with liquids in the waste to form leachate and landfill gas.
What are the pros and cons of a landfill?

What is landfill contamination?
The most serious form of water pollution from landfills is direct leachate contamination, considered a major environmental and human-health hazard. Leachate is a highly odorous black or brown liquid that commonly contains heavy metals, such a lead, and volatile organic compounds or VOCs.
What kind of pollution do landfills cause?
Landfills can cause air pollution by emitting dust and gases such as methane, carbon dioxide, and etc. These gasses are produced as a result of the decay of organic wastes by microorganisms .
What is landfill pollution?
Landfills can produce objectionable odors and landfill gas can move through soil and collect in nearby buildings. Of the gases produced in landfills, ammonia, sulfides, methane, and carbon dioxide are of most concern. Ammonia and hydrogen sulfide are responsible for most of the odors at landfills.
Does landfill cause global warming?
Soil is needed to cover fresh waste every day, and once the landfill has reached its capacity, the waste is covered with more clay and another plastic sheet. Since this waste is simply “stored” as opposed to broken down, it releases methane gas, the greenhouse gas that contributes to climate change.
What are the dangers of living near a landfill?
Previous research shows that people living closer to landfill sites suffer from medical conditions such as asthma, cuts, diarrhoea, stomach pain, reoccurring flu, cholera, malaria, cough, skin irritation, cholera, diarrhoea and tuberculosis more than the people living far away from landfill sites [31,32,33,34,35,36].
