Pyrolysis - Process of combustion in absence of oxygen or material burnt under controlled atmosphere of oxygen
Putrescibility : process of decomposition of organic matter present in water using oxygen
Excessive sand mining causes ground water depletion [since recharge will be slow]
Dioxin is carcinogenic which is the byproduct of plastic manufacturing process

Condition that is characterized by unexplained rapid loss of a Bee's colony adult population
Also called as May disease, Autumn Collapse, Spring Dwindle, Fall Dwindle Disease, Disappearing disease
Causes: Global warming, metal pollution, malnutrition, Stress, Habitat loss, Specific parasite, Neonicotinoids, electromagnetic radiation, climate change
Fungus Nosema- European Foulbrood - parasite one of the cause of CCD
Neonicotinoids - New Nicotine like insecticides - potential risk to pollinators

Study of effects of released pollutants on the environment and on the biota that inhabit it

Effect of pesticide on the environment and on the biota.
Pesticide toxicity measure in 'LD 50' => Lethal Dose 50
Lethal Dose 50 means that it will kill 50% of lab animals if exposed to that chemical for such level of Dose
Lower the value of 'LD 50' means higher the toxicity
Ex: LD 50 value of DDT is 113 mg/kg and monochrotophos is 14mg/kg => monochrotophos is more toxic

Ammonia helps in preventing ice from melting and use of formaldehyde increases the shelf life of fish therefore many people in the fisheries sector are using these chemicals
Continuous ingestion of ammonia and formaldehyde can lead to many health issues including abdominal pain, vomiting, unconsciousness, and sometimes even cause death

Microbeads are smaller forms of plastic, no greater in size than 5 mm.
Microbeads are added as an exfoliating agent to cosmetics and personal care products, such as soap, facial scrub and toothpastes.
Microbeads escape the filtration and treatment processes for waste water and end up in sites of nature.
The durable properties of plastics make them persistent and slow to degrade in the environment entering the food chains.
It is also getting dangerous as plastics are making way into the food chains of even birds, animals and fishes.
Microbeads are directly ingested by Zoo plankton and thereby enters the food chain

Fine powder of recycled plastic
Mixed with bitumen that is used to lay roads which increases its life span by 3 times
