Geoenvironmental approach to investigate surface and groundwater pollution-related problems in water-sensitive regions.

The desert environment is a clean, dynamic system due to its remoteness from human interventions. Yet, sometimes it is approached by anthropogenic activities that change its balanced ecosystem. The present study states that the non-planned construction of wastewater plants has affected the environment and led to water resource deterioration.

Satellite observations for monitoring atmospheric NO in correlation with the existing pollution sources under arid environment.

Monitoring of air pollutants using satellite data has been largely improved over the past few decades, which can provide deeper insights into the effects of anthropogenic activities on the air quality. The observations and measurements of atmospheric NO are poorly investigated in North Africa, therefore, the current study applied a multi-proxy approach to better understand of the ambient environment. This approach is based on satellite observations, chemical and biological analyses, and investigative information during fieldworks.
