Leachate is the liquid waste that is produced as organic waste decomposes. If leachate enters a stream, it can be extremely polluting. Naturally occurring bacteria in the stream will break down the waste quickly using oxygen in the water. As the oxygen levels fall, aquatic life in the stream will die.
What is meant by organic waste?
Organic waste is any material that is biodegradable and comes from either a plant or an animal . ... Examples of organic waste include green waste, food waste, food-soiled paper, non-hazardous wood waste, green waste, and landscape and pruning waste.
How does organic waste affect water?
Organic compounds in freshwater
During the decomposition process the dissolved oxygen in the receiving water may be used up at a greater rate than it can be replenished, causing oxygen depletion and having severe consequences for the stream biota.
What comes under organic waste?
Organic waste is any material that comes from either a plant or an animal, and can be decomposed by microorganisms (biodegradable) into carbon dioxide, methane, and simple organic molecules , or consists of the remains, residues, or waste products of any organism.
What is organic water pollution?
Organic Substance — Organic pollution occurs when an excess of organic matter , such as manure or sewage, enters the water. ... A type of organic pollution can occur when inorganic pollutants such as nitrogen and phosphates accumulate in aquatic ecosystems.
What is organic waste and examples?
Organic wastes are often disposed of with other wastes in landfills or incinerators, but since they are biodegradable , some organic wastes are suitable for composting and land application. Organic materials found in municipal solid waste include food, paper, wood, sewage sludge , and yard waste .
Why organic waste is harmful?
Most organic products sound innocuous enough – they are natural, after all. But there’s actually serious harm associated with its disposal in landfills. Due to the lack of oxygen , organic waste undergoes the process of anaerobic decomposition when it’s buried in a landfill.
What is organic waste used for?
Industrial uses: Provide waste oils for fuel conversion and send food waste to anaerobic digestion where it can be used for fuel and electricity production. Composting: Create a nutrient-rich soil amendment.
How does organic matter discharged into water cause pollution?
Too much decaying organic matter in water is a pollutant because it removes oxygen from water , which can kill fish, shellfish, and aquatic insects. The amount of oxygen used by aerobic (in the presence of oxygen) bacterial decomposition of organic matter is called biochemical oxygen demand (BOD).
Which is the organic source of pollution?
Organic pollutants includes phenols, chlorinated phenols , endocrine disrupting chemicals, azo dyes, polyaromatic hydrocarbons, polychlorinated biphenyls, pesticides, etc., whereas inorganic pollutants includes a variety of toxic heavy metals such as cadmium (Cd), chromium (Cr), arsenic (As), lead (Pb), mercury (Hg), ...
Which one is not organic waste?
Some examples of inorganic waste are aluminum cans, spoons, plastics, and glass. And a few instances of organic waste are paper, cardboard, and food remains.
How can we use organic waste?
By composting , you can convert organic wastes — yard trim- mings, leaves and many kinds of kitchen scraps — into a dark, crumbly mixture that can be used to improve the soil and reduce your use of fertilizer and water. Make a compost bin — or buy one. 1.

What are 3 major types of water pollutants?
Water pollutants can be divided into three major categories: (1) substances that harm humans or animals by causing disease or physical damage; (2) substances or situations that decrease the oxygen content of water, leading to anaerobic decay and the death of aquatic life ; and (3) substances that are indirectly harmful, ...
What are the effects of organic pollution?
Persistent organic pollutants cause a variety of adverse health effects, including cancer, immune system suppression , decrements in cognitive and neurobehavioral function, disruption of sex steroid and thyroid function, and at least some of them increase the risk of chronic diseases, such as hypertension, ...
What is water pollution and its effect?
Water pollution is the contamination of water bodies (like oceans, seas, lakes, rivers, aquifers, and groundwater) usually caused due to human activities. Water pollution is any change in the physical, chemical or biological properties of water that will have a detrimental consequence of any living organism.
