Evaluate Indore City's Ambient Air Quality Using the Real Time-Air Quality Index (RT-AQI)
Abstract: This effort aims to express the ambient air quality of Indore city as a real-time air quality index (RTAQI). Readings were taken early in the morning (8:00 AM to 10:00 AM) and during the evening rush hour (8.00 PM to 10:00 PM) to assess PM2.5, PM10, sulphur dioxide (SO2), nitrogen dioxide (NO2), ozone (O3), carbon monoxide (CO), and NH3 at several places in Indore. With those readings, the air quality …

Seasonal Variations of Air Quality Measures In Warri and Effurun, Delta State, Nigeria.
Abstract: Air quality in Urban Cities like Warri and Effurun has been deteriorating over time. The distribution levels of air pollutants in the Warri and Effurun environments may be related to both natural and man-made factors. In addition to evaluating the quality of rainwater with regard to pH, heavy metals (Fe, Pb, Cd, As, Hg, CU, Zn), and some anions (Cl-, NO3-, SO42-, CO32-), this project study aims to investigate, using …

Monitoring and Modeling of Atmospheric Change Indices In Parts of Imo State Using GIS, MATLAB and ANN
Abstract: Geographic Information System (GIS) and Matrix Laboratory (MATLAB) Models were used to study air quality in parts of Imo State. Primary data were obtained by conducting relevant analysis using standard instrumental methods on open-air rainwater samples collected in the dry and the rainy seasons for two consecutive years. GIS showed that the pollutants were present throughout the year. Artificial Neural Network (ANN) of MATLAB 2015 was used to represent data …

Corrosion and Corrosion Protection of Cast iron due to Bio-organism
Abstract: Cast iron is a high tensile strength metal. It is generally used for making tools, pipe fitting, electrical fitting equipment and rail track. It interacts with corrosive substances to develop electrochemical cell on their interface. Corrosive substances are acids, bases, salts, bio-wastes, particulates and pollutants. These substances produce hostile medium for materials. These harmful wastes discharge by industries, households, agricultural, urbanization, development of infrastructure, construction works, thermal power stations, hydropower, …

Health and Air Quality in High-Density Neighbourhoods of Delhi
Abstract: Delhi, one of the fastest-growing megacities in the world, continues to grapple with critical challenges of urban air pollution and its direct consequences on public health. High-density neighborhoods like Karol Bagh, Lajpat Nagar, Chandni Chowk, and East Delhi face disproportionately higher exposure to degraded air quality due to compact urban forms, overcrowding, mixed land use, and heavy traffic. This paper explores the interrelationship between air quality and health outcomes, emphasizing …
