As many of the Indian rivers are reported to be polluted, it is essential to ramp up the conservation initiatives. With 14 major river systems and more than 600 rivers, almost 80% of the subcontinent’s population is dependent on these resources for their sustenance. According to a 2022 report by Central Pollution Control Board (CPCB), there are about 311 Polluted River Stretches (PRS – stretches in rivers where BOD>3mg/L) in 279 rivers (out of 603 rivers assessed). There are about 1,631 Sewage Treatment Plants (STPs) with a total capacity of 36,668 MLD but only 20,236 MLD of installed capacity is actually utilised, while the…

Magnetic Pollution Magnetite pollution has recently been discovered by some geologists in Kolkata's roadside dust. In regions with considerable vehicular traffic and other polluting sources, pollutants occur more frequently. The quantity of magnetite varies with the volume of traffic on a particular road. The method exposes the existence of several magnetic components, and by linking them to particular pollution sources, the researchers were able to determine which sources predominate in which locations. Their research is in the field of environmental magnetism, which employs magnetism to illustrate the effects of pollution, climatic change, and environmental footprints on magnetic minerals found in…

E-WASTE In India India is now considering a switch to two standard chargers for all mobile phone brands and portable electrical gadgets, which will aid in the fight against e-waste. Similarly, the European Union (EU) has mandated that the USB-C port be standard on all devices by mid-2024, including Apple's iPhone, which now utilizes its own standard. Consumers in the European Union would no longer need to buy new charging devices and cables every time they bought a new phone under the new rule. What is E-Waste? E-Waste is an abbreviation for Electronic-Waste, and it refers to old,…

Plastic's Life Cycle According to a recent document titled "The Plastic Life-Cycle," India is not properly collecting and recycling its polymer waste. The document emphasized that the problem will not be solved unless the entire life cycle of plastic, from source to disposal, is considered as the root cause of the pollution it causes. What is plastic waste? Unlike other forms of waste, such as paper, food peels, and leaves, which are biodegradable (capable of being decomposed by bacteria or other living organisms) in nature, plastic waste persists in the environment for hundreds (or even thousands) of years. The Most…

Lead Poisoning in India According to a report by Niti Aayog and the Council of Scientific & Industrial Research (CSIR), lead poisoning causes the greatest health and financial burden in India. Principal Points of the Report Global Results: Blood lead levels (BLL) in children of up to 800 million worldwide are at or above 5 micrograms per deciliter (g/dL). Lead poisoning of children is an enormous and previously ignored global problem. Over 900,000 premature deaths per year are related to lead exposure since lead has such a significant negative effect on individuals. Many nations don't have enough official recycling infrastructure…

Fly Ash The National Green Tribunal (NGT) has emphasised the urgent need for Chhattisgarh to increase the use and disposal of fly ash. ??????? About 15 state, national, and privately owned electricity generating units are concentrated in Korba, Chhattisgarh, makes the situation much more dire. What is Fly Ash? Burning pulverised coal in thermal power plants produces fly ash as a byproduct. Clay, feldspar, quartz, and shale, mineral impurities in coal, fuse in suspension during combustion and float out of the combustion chamber with the exhaust gases. Fly ash, which are spherical glassy particles, are formed as the fused material…

Forever Chemicals In a recent investigation, researchers discovered that per- and poly-fluoroalkyl substances (PFAs) are present in rainwater from various locations throughout the world. They are also known as "Forever Chemicals" due to their propensity to persist for extended periods of time in soil, precipitation, and the environment. Additionally, PFAs are included in the Stockholm Convention. Per- and Polyfluoroalkyl Substances They are synthetic chemicals used to create nonstick cookware, clothing that repels water and oil, materials that resist stains, cosmetics, firefighting gear, and several other goods. During their creation and use, they may travel to the air, water, and soil.…

Reuse of wastewater: TADOX Technology by TERI New technology may soon enhance the reuse of wastewater in an affordable and sustainable manner. The technology which uses UV-Photocatalysis can treat municipal sewage and highly polluting industrial wastewater streams and increase its reuse as a technological option in industrial as well as municipal wastewater treatments. With the ever-increasing Water crisis and Water pollution, it becomes imperative for industries & utilities to reuse ‘treated water. However, the current treatment practices are inefficient because of their high dependence on biological treatment systems, which are unable to bear shock loads. This is followed by tertiary treatment…

Comprehensive Environmental Pollution Index The comprehensive Environmental Pollution Index (CEPI) is a rational number to characterise the quality of the environment at a given location following the algorithm of source, pathway and receptor. An increase in the CEPI score denotes adverse effects on the receiving environment. A Delhi-based think-tank Centre for Science and Environment (CSE) did an assessment of Tamil Nadu’s CEPI scores. Groundwater is becoming more polluted in Tamil Nadu’s industrial areas and Vellore is the state’s most polluted district in terms of river pollution. According to the CEPI water score 2018, five industrial clusters in Tamil Nadu were…

Gujarat River Pollution The unchecked flow of untreated industrial effluent into rivers in Gujarat has led to increasing pollution in the Sabarmati, Mahisagar, Narmada, Vishwamitri and Bhadra. According to data from the Ministry of Environment and Forest (MoEF), the Sabarmati is among the most polluted rivers in the country. Gujarat ranks fourth among the top five States with highly polluted rivers, with as many as 20 rivers in the critically polluted category. Recently, a thick froth on the Mahisagar, along a stretch of several kilometres, raised serious concern, prompting the Gujarat Pollution Control Board (GPCB) to constitute a high-level committee…

Pink Phenomenon In Avalapandi, a village in Kerala, an aquatic plant forked fanwort has painted the water bodies pink, which led to the ‘pink phenomenon’. This plant comes from the family of Red Cabomba (Cabomba furcata). Cabomba is a submerged perennial aquatic plant that grows in stagnant to slow-flowing freshwater. It is an invasive species that belongs to Central and South America. It requires a huge amount of oxygen to grow and that could badly affect freshwater biodiversity. It has a high natural dispersal potential due to its ability to readily fragment and spread. Invasive Species: Invasive alien species are…
