The air pollution generated in November 2024 in India and Pakistan was regarded by climate researchers as an unprecedented intensification of the region's annual pollution cycle. [2] NASA satellite imaging showed a continuous cloud of smog that extended across the majority of eastern and northern Pakistan, as well as northwestern India. [3] [4]
Air pollution, poor management of waste, growing water scarcity, falling groundwater tables, water pollution, preservation and quality of forests, biodiversity loss, and land/soil degradation are some of the major environmental issues India faces today. [12] India's population growth adds pressure to environmental issues and its resources.
The study reported that approximately one-fifth of the deep water wells and hand pumps operated by the Kolkata Municipal Corporation were polluted with human waste. The former director of the All India Institute of Hygiene and Public Health blamed the ongoing water pollution on a leaky sewer system and water pressure abnormalities. [7]
Over the past decade air pollution has increased in India significantly. Asthma is the most common health problem faced by Indians and it accounts for more than half of the health issues caused by air pollution. [43] [44] Air pollution is believed to be one of the key factors in accelerating the onset of Alzheimer's disease in India. [45]
Surface nuclear magnetic resonance (SNMR), also known as magnetic resonance Sounding (MRS), is a geophysical technique specially designed for hydrogeology.It is based on the principle of nuclear magnetic resonance (NMR) and measurements can be used to indirectly estimate the water content of saturated and unsaturated zones in the earth's subsurface.

While 1D NMR is more straightforward and ideal for identifying basic structural features, COSY enhances the capabilities of NMR by providing deeper insights into molecular connectivity. The two-dimensional spectrum that results from the COSY experiment shows the frequencies for a single isotope, most commonly hydrogen (1 H) along both axes.
Down To Earth Books is the magazine's publishing wing. It publishes two annuals: State of India's Environment and State of India's Environment In Figures, the country's only annual survey on the environment. The latter is a completely data-driven annual statement on the state of India's environment published every World Environment Day. [3]
A 900 MHz NMR instrument with a 21.1 T magnet at HWB-NMR, Birmingham, UK. Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field.
