Background: The development of toxicity tests regarding toxic responses of different fish species could be more effectively used in predictive toxicology and risk assessment. In this study lethal concentrations (LC50-96 h) values of copper sulphate an important toxic industrial pollutant, on Capoeta fusca were determined. Behavioral changes at different concentrations of CuSO4 were determine...

Sustainability of groundwater resources means ensuring the permanent availability of essential groundwater services for a long-time. This research was conducted to investigate the sustainability of groundwater resources in the prohibited plain of Behshahr- Bandar-e-Gaz by using water expoliation and green water scarcity indices. Initially, the green water deficit index was calculated based on t...

Background and purpose: Acanthamoeba spp. are an opportunistic protozoan in environmental sources that can cause respiratory infection and keratitis. The present study was conducted to determine the prevalence and genotypes of Acanthamoeba in rural drinking water sources in Kashan and Aran-Bidgol, Iran. Materials and methods: In this study, 162 samples from 54 drinking water sources were colle...

Flood control, artificial recharge of aquifers and attempt to optimize the utilization of the natural resources are some of the most important measures in the arid and semi arid zones that occurs by flood spreading projects. At the current study the impact of flood spreading on downstream qanat discharge at Myankooh area of Mehriz (Yazd province) was investigated. To gain this goal after collec...
