A WATERSHED-LEVEL ECOLOGICAL RISK ASSESSMENT METHODOLOGY

Assessment of Watershed Catchment Ecological Power with Taxonomy Method for Watershed Comprehensive Management (Case Study: Watershed Zydasht, Taleghan)

Nowadays watershed catchments have been introduced as the main point of permanent development in many management discussions. Watershed catchments ecological power assessment and their rankings according to different Ethological criteria is one of the important factors in watershed catchments planning and management. Taxonomy method is one of the most comprehensive planned systems for assessing...

Ecological risk assessment of heavy metals from cement factory dust

Background: The release of metals from industrial factories is one of the most important sources of environmental pollution. The present study aimed to determine the concentration of heavy metals like cadmium (Cd), chromium (Cr), manganese (Mn), nickel (Ni), and lead (Pb) in dust around the cement factory. Methods: A total of 22 dust samples were collected from areas around the cement factory...

Human and Ecological Risk Assessment

Yellow perch (YP) are metal tolerant fish that form large populations in many metal-impacted regions across Canada. While they are able to survive and reproduce successfully in environments with water and sediment metal concentrations that are toxic to many invertebrates, perch experience a suite of direct and indirect impacts. YP were studied in a series of Canadian Precambrian Shield lakes ne...
