    Determination of pollution condition in Babolroud River from viewpoint of pesticides and agrochemicals fertilizers (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: Babolroud River is one of the important rivers for fisheries and environmental aspect that locared in center part of Mazandaran province. The river has a span of 92 km starting from Albourz mountainous and end up at the southern part of Caspian Sea. This study was done for five months (3rd Feb. through 5th July, 2008) for the better understanding of pollution situation such as organophosphorous, organochlorine pesticides and agrochemical fertilizer that drainage from paddy fields and horticultures to the river. A total of three main sites for pesticides and plus five sub-sites for drainage were selected for observation in three different regions of the river (mountainous, plain and estuary). The organochlorine and organophosphorous pesticides measured by GC (ECD and TSD detectors) with US-EPA (508) and AOAC procedure and agrochemical fertilizer parameters were measured by ASTM method. The maximum concentrations of aldrin, lindane, heptachlor epoxyde, DDE and β- BHC (period 1), δ- BHC and endrin (peiod 2), heptachlor and DDT (period 3), α- BHC (period 3 & 4), dieldrin (period 4) were 6.02, 0.85, 0.51, 0.50, 0.22, 0.35, 0.23, 0.50, 0.46, 0.19 and 0.16 µg/l, respectively. The maximum concentrations of four components of organophosphorous such as Diazinon and Chlorpyrifos (period 1), Malathion (period 2), Azinphos methyl (period 3) were 1.36, 0.46, 0.44 and 2.56 µg/l, respectively. The maximum amounts of tree components of parameters of agrochemichals fertilizers indictor such as total nitrogen (period 2, sub-site 5), total phosphorus and orthophosphate (period 4, sub-site 5) and organo-phosphorus (period 3, sub-site 4) were 5990, 1290, 1220 and 336 µg/l, respectively. The maximum concentrations of organochlorine pesticides components in sediments of the river such as lindane (period 2, site 2), δ- BHC (period 1 site 3), α- endosulfan (period 1, site 2), endrin and heptachlor epoxide (period 2, site 2) and DDE (period 2, site 1) were 0.99 0.54, 0.29, 0.19 and 0.19 µg/l, respectively. The maximum concentrations of organochlorine pesticides components in fish tissue of the river such as endosulfan sulfate, lindane, endrin, δ- BHC and DDE were 0.32, 0.29 0.27, 0.25 and 0.21 µg/l, respectively.

    Monitoring of mohammadiye channel water in order to aquaculture purposes (2018)
    Iranian Fisheries Science Research Institute | Tehran, Iran
    Details
    Publication Date: 2021-05-19
    Description: In this survey the Physical and Chemical factors, heavy metals,agricultural pesticides and microbial contaminations were studied in mohammadiye channel extending Eslamshahr, Robat karim and Shahriar cities of Tehran Province during the 2011.Specimens were obtained from 5 different stations .The measured factors were temperature,DO, Cl,HCO3,COD,BOD,CO2,Mg,……. The analysis of Physical and Chemical factors of Mohammadiye channel water showed that except water temperature,all factors in comparison to the standards were at the standard level,So they are suitable for aquaculture. The result of measurements of heavy metals including lead, copper,Iron,Cadmium, Zinc and mercury in spring, summer and fall in comparison to existing standards showed that unfortunately except copper the amount of other heavy metals are higher than standard levels in the most of stations , Lead amounts at stations 2,3,4 and 5 . zinc at stations 1 and 5 , Iron at stations 1,3 and 5 , cadmium and mercury in all stations were higher than the standards for fish culture. The measured amounts of organophosphate and organochlorine pesticides and result of microbial contaminations culture were less than standard levels. Due to mean of water temperature that is high from middle of Spring to the end of summer , It is suitable for culture of warmwater fishes and because of low water temperature in the station No1 It is recommended for culture of coldwater fishes by using of 50-70gr of young fishes .
