With the use of three case studies, the article "From Lab to Reality: Environmental Chemistry's Role in Pollution Mitigation - A Case Study Analysis" delves into the real-world applications of environmental chemistry in pollution control. Environmental chemistry is examined in depth for its revolutionary impact on waste management in industry, pollution prevention in agriculture, and pollution reduction in the air. This research examines how these methods not only help reduce pollution but also have substantial financial benefits, and it shows how they do both. These results demonstrate the practical utility of carbon capture technology, phytoremediation practises, and green chemistry principles. Policy recommendations are given to encourage the widespread implementation of these methods. In order to have a greater effect on sustainable practises and pollution mitigation, environmental chemistry needs more study and development, as is emphasised in this paper.
