What are different chemicals used in firecrackers? What are legal and policy stances on the chemicals in firecrackers in India? In an attempt to prevent air pollution from firecrackers, the Supreme Court (SC) has shifted its attention to the chemicals that are used to manufacture firecrackers. Following this recently, SC has banned five chemicals i.e. […]
In February 2016, the Ministry of Environment, Forest and Climate Change (MoEFCC) unveiled a new categorization of industries based on their pollution load. The new classification is for entire industrial sectors and not for individual units. Pollution Index Pollution Index forms the criteria for categorization of industrial sectors. Pollution Index is a function of emissions […]
In the backdrop of rising industrial and vehicle pollution, air quality become an issue of social concern worldwide. Vehicular exhaust is one of the important sources of air pollution and there is an urgent need to check the extent of vehicular pollution in India. History of vehicular emission control in India In India, the vehicular […]
Central Pollution Control Board (CPCB) with the help of concerned State Pollution Control Boards (SPCBs) and Pollution Control Committees (PCCs) is monitoring the ambient air quality in the country at 346 stations covering 130 cities and towns. This is done under the National Air Quality Monitoring Programme (NAMP). Under this programme, Central Government provides funds […]

The notable points from this act are as follows: The Act makes provisions for the establishing of Central Pollution Control Board (CPCB) at the apex level and State Pollution Control Boards at the state level. The […]
Thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is re turned to the natural environment at a higher temperature, the change […]
Spread of chemicals, particles, industrial, agricultural and residential waste, noise or the invasive organisms in the marine is the Marine Pollution. Toxins bioaccumulate in Zooplankton and phytoplankton and then get biomagnified in the ocean food chains. They cause Eutrophication, ocean acidification etc. leading to problems such as algal bloom, hypoxia and anoxia. There are four […]
Persistence is an important characteristic of the environmental pollutants in an environmental medium (air/ water/ soil) or in a living tissue, in which the pollutants remain active for a longer time in a toxic form through chemical, biological, and photolytic processes. Persistent organic pollutants (POPs) are organic compounds that, to a varying degree, resist photolytic, […]
Almost 70 per cent of India’s surface water resources and a growing percentage of its groundwater reserves are contaminated by biological, toxic organic and inorganic pollutants. In many cases, these sources have been rendered unsafe for human consumption as well as for other activities such as irrigation and industrial needs. The high incidence of severe […]
There are five biofertilizers viz. Rhizobium, Azotobacter, Azospirillum, Phosphate Solubilizing Bacteria and mycorrhiza, which have been incorporated in India’s Fertilizer Control Order (FCO), 1985. Rhizobium, Azotobacter, Azospirillum and blue green algae (BGA) have been traditionally used as Biofertilizers. Rhizobium inoculant is used for leguminouscrops such as pulses. Azotobacter can be used with crops like wheat, maize, mustard, […]
