Odor pollution is one of the most complicated issue in the environment at kurkumbh industrial area. I studied its sources and dispersion, the physical and chemical properties of odor, odor emission regulations in our countries, odor control technologies as well as the state-of-the-art instrumentation and equipment that are necessary to monitor odor, e.g., chemical sensors, olfactometry, gas chromatography, and electronic noses. In kurkumbh there are many chemical and Pharmaceutical industries these industries release many of Odorous compound in surrounding environment i.e. hydrogen sulfide (H2S). Odor survey was conducted at each place of work and characteristics of odor release for each kind of business were made clear. And many researches and developments have been carried out to confirm reliable technique. Odor pollution abatement has involved a number of bodies. A complete explanation of pollution abatement and the development of the accompanying instrumentation technology are therefore critical links to understand the whole dimension of odor pollution in the environment. We describe the applicability of these sensorbased methods with respect to practicality in various environmental settings. Finally, we highlight the limitations and the future prospects of these sensor-based methods.
