“…Second, Kriging spatial interpolation was used to create continuous surfaces of each of the three metal(loid)s (i.e., aluminum, iron, and silicon), respectively, from the sample data, which allowed us to better visualize the spatial patterns of fly ash metal(loid)s across the study area. Among numerous spatial interpolation approaches, Kriging is an accurate geostatistical method for estimating values of spatially intensive variables (e.g., diffusion of fly ash) at unknown locations based on sampled data points. − …”

Children who live near coal-fired power plants are exposed to coal fly ash, which is stored in landfills and surface impoundments near residential communities. Fly ash has the potential to be released as fugitive dust. Using data collected from 263 children living within 10 miles of coal ash storage facilities in Jefferson and Bullitt Counties, Kentucky, USA, we quantified the elements found in nail samples. Furthermore, using principal component analysis (PCA), we investigated whether metal(loid)s that are predominately found in fly ash loaded together to indicate potential exposure to fly ash. Concentrations of several neurotoxic metal(loid)s, such as chromium, manganese, and zinc, were higher than concentrations reported in other studies of both healthy and environmentally exposed children. From PCA, it was determined that iron, aluminum, and silicon in fly ash were found to load together in the nails of children living near coal ash storage facilities. These metal(loid)s were also highly correlated with each other. Last, results of geospatial analyses partially validated our hypothesis that children’s proximity to power plants was associated with elevated levels of concentrations of fly ash metal(loid)s in nails. Taken together, nail samples may be a powerful tool in detecting exposure to fly ash.

“…Hotspot analysis is mostly used in investigations of highly affected areas, where actual datasets are more important; otherwise, road accident or safety identification do not examine hotspot areas [ 84 ]. Hotspots were established at equal intervals, and very low, low, medium, high, and very high accident-prone zones were determined [ 85 , [86] , [87] ]. The polygon, line, and point datasets were applied for hotspot examination in different software packages, and the hotspot area was also manually identified.…”

“…The chemical property like AOD is also calculated for estimating the chemical concentration of India. The anthropogenic activities, industrial works, and climatic condition phenomena are mostly affected by environmental health and public health emergencies 13 , 43 .The investigational outcomes are helpful for the planners, disaster management team, and administrators for protecting environment otherwise human activates and overwhelming population pressure can destroy natural environmental conditions.…”

Climatic condition is triggering human health emergencies and earth’s surface changes. Anthropogenic activities, such as built-up expansion, transportation development, industrial works, and some extreme phases, are the main reason for climate change and global warming. Air pollutants are increased gradually due to anthropogenic activities and triggering the earth’s health. Nitrogen Dioxide (NO2), Carbon Monoxide (CO), and Aerosol Optical Depth (AOD) are truthfully important for air quality measurement because those air pollutants are more harmful to the environment and human’s health. Earth observational Sentinel-5P is applied for monitoring the air pollutant and chemical conditions in the atmosphere from 2018 to 2021. The cloud computing-based Google Earth Engine (GEE) platform is applied for monitoring those air pollutants and chemical components in the atmosphere. The NO2 variation indicates high during the time because of the anthropogenic activities. Carbon Monoxide (CO) is also located high between two 1-month different maps. The 2020 and 2021 results indicate AQI change is high where 2018 and 2019 indicates low AQI throughout the year. The Kolkata have seven AQI monitoring station where high nitrogen dioxide recorded 102 (2018), 48 (2019), 26 (2020) and 98 (2021), where Delhi AQI stations recorded 99 (2018), 49 (2019), 37 (2020), and 107 (2021). Delhi, Kolkata, Mumbai, Pune, and Chennai recorded huge fluctuations of air pollutants during the study periods, where ~ 50–60% NO2 was recorded as high in the recent time. The AOD was noticed high in Uttar Pradesh in 2020. These results indicate that air pollutant investigation is much necessary for future planning and management otherwise; our planet earth is mostly affected by the anthropogenic and climatic conditions where maybe life does not exist.
