Which among the following is biodegradable pollutant :- 1 lead compounds 2 DDT 3 domestic wastes 4 mercuric salts?
Biodegradable pollutants: These pollutants are natural organic substances which can be decomposed or consumed by natural microbial or biological processes and converted into CO2, water, or simple organic molecules.
DDT, plastics, polythene, lead vapour, silver foils, etc. are non-biodegradable pollutants.
Those pollutants which are decomposed by bacteria like, vegetables and fruits leftovers, sewage, cow dung etc. are called biodegradable pollutants. Non-biodegradable pollutants are those which cannot be decomposed by bacteria e.g., mercury, polythene, aluminium DDT etc.
Biodegradable pollutants are those which are decomposed by bacteria e.g., sewage, cow dung, fruit, vegetable etc. Non-biodegradable pollutes are those which cannot be decomposed by bacteria. e.g., mercury, aluminium, lead , copper, DDT etc.
Few examples of these biodegradable pollutants include urine, faecal matter, domestic waste, sewage, agriculture residues, wood, paper, cloth, cattle dung, plants, vegetable stuff, animal bones, leather, wool, etc.
Domestic wastes (garbage), urine, faecal matter, sewage, agriculture residues, paper, wood, cloth, cattle dung, animal bones, leather, wool, vegetable stuff or plants are biodegradable pollutants. 2.
Non-biodegradable things include of plastics, polystyrene, plastic, metals, and aluminum cans, toxic chemicals, paints, tyres, etc.
DDT is an insecticide which is a non-biodegradable pollutant.
It doesn’t result in land pollution. The substances that can’t be decomposed or degraded as smaller, harmless simpler substances are called Non-Biodegradable pollutants.
- Paper and food waste.
- Human waste.
- Sewage sludge.
- Hospital waste.
- Slaughterhouse waste.
- Dead animals and plants.
- Food waste.
Examples of Biodegradable material are: Human and animal waste. (Such as Fecal matter) Plant products such as wood, paper, food material etc.
For Ex:Plant waste,animal waste,paper,cotton,cloth,woollen cloth,jute,wood are all biodegradable material. … A material which does not get decomposed through natural processes (such as action of bacteria)are called as non- biodegradable material. For Ex:Plastics,glass,metals,aluminium cans etc.
- Biodegradable pollutants:
- Those pollutants which can be broken down into simpler, harmless, substances in nature in due course of time (by the action of micro-organisms like certain bacteria) are called biodegradable pollutants. …
- Non-biodegradable pollutants:
- Nitrogen oxides (NOx)
- Sulfur oxides (SOx)
- Particulate matter (PM)
- Ground level ozone (O3)
- Volatile organic compounds (VOCs)
- Mercury (Hg)
- Peroxyacyl nitrates (PANs)
- and more.
Option (C) is correct. Kitchen waste is a biodegradable waste as it can easily be decomposed by microorganisms. Such as peels of vegetables and fruits are biodegradable. Whereas Aluminium Cans, Plastic, and DDT are non- biodegradable wastes as they can be broken down into small pieces by living organisms.
Therefore, from the above statements we can conclude that domestic waste is only the biodegradable pollutant.

Some of the examples of non-biodegradable items are Plastic bags, plastic bottles, detergents, bakelite, DDT, PVC, glass, computer parts, batteries, metals, etc. Wood, paper, leather, grass are biodegradable items.
The answer is No. Aluminum foil is not biodegradable. This means it can remain in the land for an extended long time.

Things like paper, wood, cloth made up of natural fibre are biodegradable. Things like polythene bags, razors, etc. are non-biodegradable.
Air, water and light would cause it to biodegrade. … Many plastics do not biodegrade to any significant degree, regardless of environmental conditions, while some do so very slowly if exposed to air, water and light – both types are best recycled or used for their stored energy.
Non-biodegradable materials like glass do not decompose quickly. In fact, glass bottles can stay intact in the environment for hundreds of years. It’s thought glass bottles will never biodegrade, but they will break down slowly.
Biodegradable substances include food scraps, cotton, wool, wood, human and animal waste, manufactured products based on natural materials (such as paper, and vegetable-oil based soaps).
Biodegradable wastes are those substances that degrade or break down naturally. Non-biodegradable wastes are those substances that do not degrade easily. Materials like plants, animals, their waste, paper, fruits, vegetables fall under the category of biodegradable substances.
Glass, metals, electronic devices, computer parts, batteries, medical waste, plastic bags, plastic bottles, tetra packs, and carbon paper are a few examples of non- biodegradable materials.
Sewage is mainly biodegradable and most of it is broken down in the environment. In developed countries, sewage often causes problems when people flush chemical and pharmaceutical substances down the toilet.
polyhydroxy butyrate −CO−β hydroxyl valerate (PHBV) is a biodegradable polymer.
