Background and Objective: Nowadays linear alkyl benzene sulfanate (LAS) is widely used in the production of various detergents. The purpose of this study was to assess the health and ecological hazards of this pollutant on target organisms such as fish and daphnia in the Doroodzan Dam water. Materials and Methods: According to the research objective and given existing restrictions, 21 water sa...
The concentration of selected trace metals (Fe, Cd, Cu, Pb, and Zn) in 30surface sediments were measured using Atomic Absorption Spectrometer to investigatethe spatial and seasonal variations of trace metals along Kanyakumari coast, India. Toassess the environmental risk of trace metals, enrichment factor, geo-accumulation index,pollution load index, and ecological risk index have been calculat...

Background and Objective: Identification of potential risks in laboratories and trying to create safe conditions for the staff is very important from different aspects. The main objective of this study was to evaluate the potential risks in the laboratories of three research centers affiliated to Iranian Fisheries Science Research Institute. Materials and Methods: In order to assess and clas...
Background & Objective: The road traffic has become one of the main sources of metal pollution and could affect roadside soils. Therefore, this study was conducted to assess the pollution and toxicity potential of Pb, Cd, Cr and Ni in surface soils along some roads of city of Hamedan in 2019. Materials & Methods: In this descriptive cross-sectional study, a total of 63 surface soil samples were...
The current situation in the risk society characterised by new realities (from global climate change to pandemic penetration of a virus human body) has brought light need turn paradigm posthumanism, i.e. supplementing unequivocal optimistic orientation on sustainable development with more pessimistic, but also topical and realistic, survival strategy aligned extreme ethics, for ecological secur...
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...
a methodology of ecological risk assessment for the terrestrial ecosystem under chronicradioactive pollution of a biotope near a regional radioactive waste storage has been developed in terms of thecritical environmental loads analyzed. it consists of five stages: determination of effect indicators and assessmentof their values; establishment of reference species and indices; assessment and ana...
