Spatial analysis of the effect of ASPERGILLUS SPP on groundwater in the (Najaf-Karbala) plateau within the center of Najaf district and Al-Haidariya sub-district

Abstract

The research sought to analyze the spatial and temporal variation of soil contamination with Aspergillus spp on groundwater in the (Najaf-Karbala) plateau within the center of Najaf district and Al-Haidariya district, by taking (22) sites and (88) samples in four seasons (summer, autumn, winter and spring) and then they were diagnosed and analyzed microbiologically and their types and numbers and the effects caused by these pathogenic species on humans, animals and plants were known. Their spatial variation was also known, as it was found that there are sites that record the highest presence of Aspergillus spp in the study area, on the contrary, there are sites that did not record any presence of this fungus. The temporal variation between the seasons was also known, as autumn and spring recorded the highest presence, then winter in third place, and finally summer recorded in terms of the total number of Aspergillus spp in the study area. Finally, the research concluded that the study area constitutes an environmental hazard that threatens residents with groundwater contamination with Aspergillus spp and what This fungus causes dangerous diseases for humans, animals and plants.
