background: in the recent years, eutrophication has become a serious challenge for many of the water ecosystems. it has affected the environmental and economical aspects of the anzali wetland, which is known as one of the significant ecosystem. due to the increase of the nutrient loadings from the industrial, agricultural and human activities, the wetland’s health is faced many serious problems...

background: evaluation of heavy metals as toxic pollutants in environment has a significant importance in environmental pollution studies. surficial sediments of water resources have a high potential in releasing heavy metals to the upper water environment, hence sediment analysis presents guidelines to the authorities for monitoring the environmental systems. methods: in this study, total and ...

following the occurrence of two large outbreaks in gilan province, northern iran, the public health importance of human fascioliasis has increased significantly. the mixed infections of fasciola gigantica and f. hepatica within a given domestic animal individual suggest a very complicate picture of possible circulation ways of the parasite and the possibility for humans to be infected with both...

background: the most important factors and problems threatening the anzali wetland are the contaminant load and sediments entering the wetland, as well as lack of an integrated management plan for this wetland. the main objectives of the current research were to explore whether there are significant differences in concentrations of zn, cd, and pb in surface sediments among different sites (base...
