| Abstract |
| Assuit Governorate attracted few researchers despite the plenty of resources and activities. Therefore, the present paper aims to assess the quality characteristics of the available water bodies, air, and agricultural lands of Assuit governorate using spatial and laboratory analyses integrated with remote sensing techniques. To fulfill this aim, a field survey was conducted for identifying the dominant anthropogenic activities, collecting water and soil for further lab analyses of physical and chemical characteristics. Further, calibrated space-borne multispectral Landsat images dated 1999, 2009, and 2019 were processed to retrieve the Particulate Matter (PM10) to assess air quality over the governorate. A similar spatial distribution of PM10 over Assuit governorate was recorded during the three investigated years; 1999, 2009, and 2019 which exceeded the allowable Egyptian threshold limits over the urban and the desert lands basically as a result of natural factors with a contribution from emissions of the urban areas. Results reported the discharge of domestic wastewater into some irrigation canals as the main reason for elevating turbidity and Organic matter levels. Reasonable Electric Conductivity (EC) levels were recorded (277 to 1094.00 µs/cm) which showed good to permissible levels for irrigation. The investigated water parameters of the River Nile are coinciding with the Egyptian threshold limits. Remarkable fluctuations were observed in the levels and the spatial distribution of most of the soil characteristics in Assuit. The spatial trend showed that levels of soil pollution are increasing southward which is confirmed by the positive correlation between the indicators of pollution. |
