ports’ activities could result in oil spills occurrences and oil pollution in different ways including the discharges of ships’ oily wastes, discharges of oily ballast water and leaks at oil terminals. in this paper, using the results of the analyses of the hydrocarbon compounds in the samples collected from the sediments in the anzali port in the caspian sea in iran, the levels of oil pollutio...
population of vimba vimba persa was investigated using microsatellite markers originated from two regions along the iranian coastline of southern caspian sea (anzali lagoon and havigh river in gilan province). totally 153 alleles were identified. the highest number of alleles per ca3 loci was 17 and the lowest 3 in z8145 loci with means of 7.6. observed and expected heterozygosity averages were...
land use effects on heavy metal pollution of river sediments in guilan, southwest of the caspian sea
studies have showed the river siahroud is the main contributor to the present pollution of anzali wetland in guilan. therefore, this study was initiated to evaluate the spatial distribution of metals pollution on the river siahroud sediments in guilan.surfacial river sediment samples along this river were taken during five consecutive seasons at eight sampling stations and analyzed for availabi...
Over the last few decades, Anzali wetland has been at risk of pollutants, especially from heavy metals. The present research analyzes some physical and chemical properties and heavy metals concentration in 27 points in nine stations of Anzali wetland. The samples of each station have been mixed, acidic digested, and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The mean con...
Following an outbreak of fascioliasis in Anzali Harbor in 1988, 452 blood samples were collected using a multistage sampling method for hematological and serological studies. After determination of eosinophilia in the samples, antifasciolia antibodies in the sera were also determined using enzyme linked immuno sorbant assay (ELISA) and counter-current immuno electrophoresis (CCIE). 64.2% ...
One of the unique and important aquatic species of Anzali wetland, Anadonta cygnea, native Anzali wetland and its rivers, and the most important two-body system of this blue system, has declined sharply in recent years due to various reasons. Is this species is considered to be smuggling and has a special sensitivity to environmental changes (biological pollution assessment).Anzali Wetland is a...
this study was conducted to determine length-weight and length-length relationships, relative condition factor (krel) and fulton?s condition factor (k) for five species including scardinius erythrophtalmus, carassius auratus gibelio, cyprinus carpio, tinca tinca and hemiculter leucisculus belonging to cyprinidae family. fish sampling was carried out by gill net and fyke net in the western regio...
Measuring salinity of water at different depths along six transacts at the mouth of the wetland and along five tributaries connecting the wetland to the sea the extent of Caspian Sea penetration into Anzali Wetland was determined. The results demonstrated a depth-dependent salinity gradient extending up to 10 kilometres into the wetland. A pattern of saltwater and freshwater interface is presen...
background : cats play a crucial role in the epidemiology of gastrointestinal helminthic parasites and also play a major role in transmitting of these parasites through faecal contamination of soil, food or water. the aim of this study was to determine the species of gastrointestinal helminthes parasites in stray cats from a rural area of bandar-e-anzali, iran. method: gastrointestinal helminth...
