  This investigation was carried out in 2013 to measure the concentration ofagricultural organochlorine pesticide DDT in muscle tissues of three fish speciesincluding Cyprinus carpio, Rutilus frisii kutum & Liza auratas in eight stations insouthern coast of the Caspian Sea (Bandar Torkaman, Khazarabad Sari,Fereydunkenar, Chalous, Kiashahr, Bandar Anzali, Hashtpar and Astara), Iran. In eachstation, five fish samples per species were caught and the concentration of thepesticide were measured by gas chromatography – electron capture detector (GCECD)in each of them. The average amount of DDT in C. carpio, R. frisii kutum & L.auratas were 0.11 ±0.24, 0.17 ±0.25 and 0.163 ±0.25 ng/g fresh weight,respectively. The most contaminated stations in terms of DDT contamination wasKiashahr (averagely, 0.64 ±0.02 ng/g based on fresh weight). In all stations, amountof DDT was lower than the maximum residue limit (0.28 mg/g fresh weight).Moreover, the level of the pesticide, DDT, in muscle tissue of the fish from all stationswas not higher than acceptable daily intake (ADI). The levels of DDT in studied fishesare significantly lower than in 2008. Manuscript profile

  The North Atlantic oscillation (NAO) is one of the effective indices in changing atmospheric situation of northern hemisphere .Southern coastal region of Caspian Sea is affected by different atmospheric systems and teleconnections such as NAO because of its special geographical situation. In this research, precipitation and temperature data of southern coastal region of Caspian Sea are examined for 8 synoptic stations in 1977-2009 period. NAO index data are also received from cpc.noaa.gov website. Precipitation and temperature data were examined with their corresponding NAO indices data by correlation test in monthly and yearly time scales. Furthermore, we found that in this region, when NAO index increases, precipitation will increase and temperature will decrease and vice versa. During recent years, NAO index shows negative trend, so we expect decrease of precipitation and increase of temperature in the region.     Manuscript profile
