An Introduction To Environmental Chemistry And Green Chemistry And The Difference Between Green Chemistry And Environmental Chemistry

, 2022
Abstract As you see in the current situation, pollution is a global challenge. It affects the worldwide population, not even in India. The government has many policies to stop pollution, but still, it’s very challenging for us. The primary aim of environmental chemistry is to minimize the pollution in the environment and also the impact of the ...
