“…Tajan an in valuable ecosystem is located in Mazandaran province in northern Iran and the southern Caspian Sea. Tajan basin has a unique position in terms of economic, social and environmental issues due to its suitable and diverse climate and habitation (4). This river with a length of about 140 km emanates from The Mountains of Ali Khani, Darab Mountain and Sarkuh from the mountainous area of Hezarjarib on the northern slopes of the Alborz Mountains and falls into the Caspian Sea by crossing the east of Sari.…”

Journal homepage: www.zums.ac.ir/jhehp Background: Iran is located in the global arid zone. With an average rainfall of less than 250 mm. 25 percent is Iran of located in hyper-dry area and 40 percent in the arid area. In 2007, the World Bank report declared the annual reduction of freshwater resources in Iran 6 times more than global standards and indicators. Since at present, in Iran most available fresh water enters the water ecosystems, their management is vitally important due to climate changes and water quality parameters. Methods: In this study, long-term changes of some parameters including hardness, dissolved solids and EC, pH, HCO3, Ca, Na, Mg, Cl and SO4 were investigated for a period of 44 years in two key rivers (Neka and Tajan rivers) in the north of Iran. Results: The results show that there was the same changes pattern in all parameters in both rivers. The highest level of correlation was between electrical conductivity and dissolved solids in both rivers. Also, due to the similarity of the hydrological characteristics of the rivers, the impact of area development by local people is playing a major role in the environmental health. Conclusion: Although Iran's northern regions have high rate of precipitation, status of water quality parameters is an indicator of low levels of water quality and its pollution.

Abstract:Harnoi stream water quality is severely affected by urban population activities, which resides nearby the stream. The present study was conducted for the assessment of various stream water sites. The aim of the study was to check the effect of various point and nonpoint sources of pollution, on the stream water quality. The study area was divided into three main sites, upstream, polluted and downstream site. These three sites were combined together at river 'Dorr', near Havalian, which ultimately mix with river Indus at Tarbela. Main assessment biological parameters included algal, macro invertebrates, bacteriological and fungal analysis. Other physicochemical parameters included pH, temperature, electrical conductivity, Total Dissolved Solids (TDS), Dissolved Oxygen (DO), NaCl and turbidity. Higher conductivity value of 680 µS cmG 1 was found in the month of October, which was higher in polluted site in all 8 months. The TDS higher value of 497 ppm was found in the month of October but the values were below Pak NEQS. Harnoi stream was dominated by Cyanobacteria and Oscillatoria. Macro-invertebrate at pollutant stream site included tolerant species, such as, tubifex, plectus, leech, sewage fly, dero, snails, midge fly larva, black fly larva and carp. Higher gram negative bacterial count showed fecal contamination, which is vulnerable for the stream water quality. It is concluded from the results obtained that, some immediate remediation strategies, like, wetland construction and growth of pollution control plants, are necessary to control the situation.

“…Aquatic organisms such as fish and molluscs serve as bioindicators of pollution, due to a great deal of response and sensitivity to changes in the aquatic environment, which plays an increasingly important role in biomonitoring of environmental pollu-tion. Biomarker was considered as the reliable method to evaluate the biological response towards environmental risk so that preventive measures can be taken [3,4].…”

Stressful environmental conditions are ecological force in modulating adaptive responses of fish populations in aquatic ecosystems with a large number of biochemical and physiological effects associated with increased fluxes of oxyradicals. This study was aimed to examine the impacts of oxidative stress and histological changes in organs of Chrysichthys nigrodigitatus from Ologe and Badagry lagoons. Biomarkers such as biochemical markers [malondialdehyde (MDA) and superoxide dismutase (SOD) and catalase (CAT) and glutathione (GSH)] and histological marker were analysed in C. nigrodigitatus using standard protocols. The biochemical response of C. nigrodigitatus indicated that there was significant increase (p < 0.05) in the activities of MDA and SOD, as well as CAT and GSH in the gill, liver and muscle of the fish samples of both lagoons. The CAT activities in the muscle negatively correlated with MDA in gill (p < 0.05, r =-0.848) in Ologe lagoon. The histological changes in the gill exhibited mild epithelial lifting, fusion of secondary lamellae; inter-lamella hyperplasia, desquamation and necrosis of secondary lamellae. Furthermore, the hepatic tissue showed disseminated moderate microvesicular vacuolation of hepatocytes, moderate vascular congestion and mild presence of eosinophilic fluid within the interstitial. The renal tissue also showed mild hemorrhagic lesion, mild moderate ballooning degeneration of renal tubules and thickened blood vessel. The study provides baseline information that can be useful for effective biomonitoring and future comparative studies of oxidative stress and histomorphological changes in aquatic biota from polluted coastal ecosystems.
