waste is any substance that is considered not useful in the environment and can be harmful to human health.We have two types of waste which are solid and liquid waste, the solid waste consist of used plastic bags, damage home appliance, etc. whiles liquid waste consist of used water from bath, washing, decompose fecal matter and oil.
The danger related to poor waste management
To clarify this , waste management means the best practice for The waste handling, collection, transportation for re- use , recycling (for recyclable materials) and recovery the organic for energy production for fertilizer , finally the useless waste that cannot be re- use , recycled or recover should go to a sanitary landfill, if there is poor waste management , that means poor handling , collection , transportation and dumping and this will results in negative impacts on human health and environment that can be summarized as follows:
Uncollected wastes cause placed on the on the ground, will result in unsanitary conditions specially during the rainy season
Polluted water flowing from waste dumps and disposal sites can cause serious pollution for the surface water and the surrounding environment
Flies and Mosquitoes breed in some constituents of solid wastes, flies and rats are very effective vectors that spread disease.
Dangerous items such as broken glass, razor blades, needles and other healthcare wastes pose risks of injury or poisoning, particularly to children and people who are engaged in waste sorting and handling.
Burning waste on the disposal sites can cause major air pollution, affect the climate change by increase the GHG emissions ,beside the effect on human health by causing illness (respiratory diseases) and the risk of fire can spread to the adjacent properties, and make disposal sites dangerously.
Poor waste disposal practices lead to: The accumulation of harmful substances. A breeding ground for bacterial diseases. A place where pathogenic parasites can grow. It causes:
Surface water contamination.
water pollution.
Soil contamination:
land and air pollution and can cause respiratory problems and other adverse health effects
bulletMunicipal wellbeing:
cities with poor living standards.
Imagine we all throw garbage, junk and rubbish away anyhow. Imagine there was no authority to supervise waste management activities from all the sources mentioned earlier. Imagine we all just sent our rubbish to the landfill, or just dumped them in a nearby river. What do you think will happen? A disaster!
Environmental EffectsSurface water contamination: Waste that end up in water bodies negatively change the chemical composition of the water. Technically, this is called water pollution. This will affect all ecosystems existing in the water. It can also cause harm to animals that drink from such polluted water.Soil contamination: Hazardous chemicals that get into the soil (contaminants) can harm plants when they take up the contamination through their roots. If humans eat plants and animals that have been in contact with such polluted soils, there can be negative impact on their health.Pollution: Bad waste management practices can result in land and air pollution and can cause respiratory problems and other adverse health effects as contaminants are absorbed from the lungs into other parts of the body. Leachate Liquid that forms as water trickles through contaminated areas is called Leachate. It forms very harmful mixture of chemicals that may result in hazardous substances entering surface water, groundwater or soil.
Economic EffectsMunicipal wellbeing: Everyone wants to live and visit places that are clean, fresh and healthy. A city with poor sanitation, smelly and with waste matter all over the place do not attract good people, investors and tourists. Such cities tend to have poor living standards.Recycling revenue: Cities that do not invest in recycling and proper waste control miss out on revenue from recycling. They also miss out on job opportunities that come from recycling, composting and businesses that work with them.
