Chemical oxygen demand (COD) refers to the oxidant content consumed by treating water samples with a certain strong under conditions, which is expressed in mg/L. This index widely used world reflect degree of organic pollution water. Using heterotrophic bacteria such as Bacillus sp. reduce COD value wastewater has become common technology.

This study investigated the levels of pollutants such as volatile organic compounds (VOCs), pesticides, herbicides, and heavy metals in air, water, soil samples, using advanced chromatographic techniques. Air samples were analyzed via Gas Chromatography-Mass Spectrometry (GC-MS) after thermal desorption, while water assessed High-Performance Liquid Chromatography (HPLC) (GC) for contaminants metals. The research employed rigorous sampling techniques, including grab composite methods, calibration certified reference materials. Results revealed significant variations pollutant concentrations across different environmental matrices sites. Notably, showed elevated pesticide levels, exhibited concerning like lead cadmium. Statistical analysis indicated differences locations, which could pose risks to both human health ecosystems. underscores importance continuous monitoring regulatory oversight mitigate impacts these contaminants. findings suggest that stricter regulations more sensitive analytical methods are necessary effective pollution control.
