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.

Air pollution caused by industrial plants (a factory at Yangtze River) Environmental issues in China had risen in tandem with the country's rapid industrialisation, as well as lax environmental oversight especially during the early 2000s. China was ranked 120th out of the 180 countries on the 2020 Environmental Performance Index. [1]
Water supply and sanitation in China is undergoing a massive transition while facing numerous challenges such as rapid urbanization, increasing economic inequality, and the supply of water to rural areas. [8] Water scarcity and pollution also impact access to water. [9] [10]
The immense population growth in the People's Republic of China since the 1980s has resulted in increased soil pollution. [citation needed] The State Environmental Protection Administration believes it to be a threat to the environment, food safety and sustainable agriculture. 38,610 square miles (100,000 km 2) of China's cultivated land have been polluted, with contaminated water being used ...
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.

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.
The severe smog is raising awareness in re-assessing China's air pollution. On 12 February 2014, China's cabinet announced that government will implement a series of measures aimed at shifting the primary energy source from coal to natural gas and renewables. Pricing mechanisms will be used to favor cleaner alternatives to coal.
