The present study aims to effectuate the contribution of environmental chemistry techniques into the development of chemistry engineering methods in order to tackle the problem of outdoor air and soil pollution. The study objective is to analyze pollutants' characteristics comprehensively and to design pollution control technologies that respond to different environmental issues and challenges. The observed results indicate remarkable progress in the pollutant removal efficiencies, as exemplified by the electrostatic precipitation systems exhibiting a PM removal efficiency of more than 90% as well as low energy consumption levels of 0.0. 5 kWh/m³. Selective Catalytic Reduction (SCR) Techniques which displays the NOx emission efficiencies exceeding 90% essentially whereas Flue Gas Desulphurization (FGD) Units becomes successful as the efficiency in SO2 removal process would overpass even 95%. VOC removal from the ambient air using activated carbon fulfills the requirements of the environmental regulations as its adsorption capacity reaches over 200 mg/g and there are sections of the adsorbent where it will be possible to regenerate. Biochar application intercepts heavy metal leaching by 80%, and moreover, enhances soil pH around contaminated settings. The advanced oxidation technologies leads to more than 90% degradation of the persistent organic pollutants, which are substituted by PCB and PAHs. Chemical engineering's integration with environmental chemistry's principles serves to provide pollutant mitigation methods, while leading the way for preservation of a greener and healthier environment
