Abstract

After inundation, water quality surveys were designed and implemented during November 2005 to September 2006 at six locations, 4 in the Hor Al-Hammar (Al-Barga, Al-Nagara and Al-Baghdadia 1 and 2) the other 2 locations in Hor Al-Hwaaiza (Um Al-Warid and Um Al-Neiach). The sampling locations were selected to cover the distribution of the pollutants in these marshes. Physical and chemical stressors including the natural water quality parameters, dissolved oxygen (DO), biological oxygen demand (BOD), turbidity, total suspended solids (TSS), total dissolved solids (TDS), electrical conductivity (EC), total hardness (TH), temperature, salinity and pH as well as nutrients were studied. The mean range of the following parameters were recorded: pH (7.56-7.84), EC (1.29-3.22 mmohs/cm2), Ca (87.18-130.26 mg/l), Mg (60.35-111.17 mg/l), Cl (304.7-753.31 mg/l), TSS (11-38.58 mg/l), TDS (891-2040.42 mg/l), DO (5.16-10.05 mg/l), turbidity (4.57-39.03 FTU), salinity (0.53-1.7 ppt), water temperature (21.09-22.47 C°), air temperature (23.54-35.26 C°), SO4 (285.73-663.89 mg/l), HCO3 (204.39-255.22 mg/l), and TH (481.67-777.5 mg/l). These marshes are also rich in nutrient especially nitrate and phosphate which enhance their suitability for growth and billings of aquatic plants and phytoplankton. Also the seasonal variation of all the parameters were monitored during this study, and the result showed some fluctuation in some of them during different seasons at different locations of the marshes. The results obtained during this survey established important background information and a baseline for further restoration work and indicate reasonable signs of successful restoration.

伊拉克南部沼泽的水质

洪水过后，2005年11月至2006年9月期间在6个地点设计并实施了水质调查，其中4个在哈马尔河(巴尔加河、纳加拉河和巴格达迪亚河1号和2号)，另外2个在哈瓦伊扎河(乌姆瓦尔德河和乌姆尼阿奇河)。采样地点的选择是为了覆盖这些沼泽中污染物的分布。对天然水质参数、溶解氧(DO)、生物需氧量(BOD)、浊度、总悬浮固体(TSS)、总溶解固体(TDS)、电导率(EC)、总硬度(TH)、温度、盐度、pH以及营养物质等理化应激源进行了研究。记录了以下参数的平均范围:pH(7.56 ~ 7.84)、EC (1.29 ~ 3.22 mmohs/cm2)、Ca (87.18 ~ 130.26 mg/l)、mg (60.35 ~ 111.17 mg/l)、Cl (304.7 ~ 753.31 mg/l)、TSS (11 ~ 38.58 mg/l)、TDS (891 ~ 2040.42 mg/l)、DO (5.16 ~ 10.05 mg/l)、浊度(4.57 ~ 39.03 FTU)、盐度(0.53 ~ 1.7 ppt)、水温(21.09 ~ 22.47℃)、气温(23.54 ~ 35.26℃)、SO4 (285.73 ~ 663.89 mg/l)、HCO3 (204.39 ~ 255.22 mg/l)、TH (481.67 ~ 777.5 mg/l)。这些沼泽还富含营养物质，特别是硝酸盐和磷酸盐，这增强了它们对水生植物和浮游植物的生长和生长的适应性。同时对各参数的季节变化进行了监测，结果表明，在不同的湿地位置，不同的季节，部分参数存在一定的波动。这次调查的结果为进一步的修复工作建立了重要的背景资料和基线，并显示了成功修复的合理迹象。
