Abstract:
ان نمو النباتات في مواقع ملوثة قد يعرض صحة المستهلك للخطر سواء اكان انسان? او حيوان?، لذلك انجز هذا البحث لتقييم التلوث بالعناصر الثقيلة في مياه المخلفات الصناعية للحي الصناعي في مدينة سامراء وفي التربة والنباتات الواقعة على مجرى هذه المياه الجارية في ساق | The growth of plants in contaminated sites may expose consumers' health at risk, whether a human being or animal so accomplished this research to assess the pollution heavy elements in the waters of industrial waste of the neighborhood's industrial city of Samarra, in soil and plants located on the course of this running water in a stream length of 800 m even downstream Tigris River, as they are put waste industrial district as well as sewage water into the river is directly without treatment, as the study was to take part of the water and soil of that region as well as four types of plants that grow where is the tail of the seven, mint, sugar cane and corporal parents, study Some qualities Physical and chemical soil and water in addition to study some changes anatomical got to plants due to pollution, and that by dividing the study area into four zones as is the region (1) part near the industrial district and region (2) is located just 200 meters from the site of No. (1) towards the river, followed by site number (3), which is 200 m from the site of No. (2) The region (4) is located near the bank of the river and about 200 m from the site number (3) and samples were taken control of the West Bank of the Tigris River, was measurement of both pH and electrical conductivity and salinity in addition to measuring some heavy elements (iron, copper, cadmium) of soil and water, as well as the measured requirement vital for oxygen and the degree of turbidity of the water, also included the study to measure some heavy elements (iron, copper, cadmium) in plant and study the anatomical changes that occur due to the pollution produced by the launch of industrial waste. The results of the study that there is variation among study sites for each of the regions of the east bank of the river (the contaminated samples) and the West Bank of the river (the control) for most attributes Physical and chemical water and soil as well as for changes anatomical plants between contaminated samples and the control and in general has The results are within the limits permitted by the World Health Organization, the results indicate the high concentration of copper in the soil compared with iron and cadmium as the highest concentration has 10 ppm at the site (1), while the concentration of sample control 0.17 ppm The iron was higher focus him in the soil is 5.2 ppm in both locations (3) and (4), while the concentration of sample control 3.3 ppm The cadmium was the highest concentration has 0.43 ppm at the site (2), while the concentration of sample control 0.15 ppm and these concentrations are all not exceeding the allowable limit for the World Health Organization (for cadmium 1.5ppm of iron 120ppm copper 40ppm) respectively, and the results showed variation in pH between the soil and water for study sites on the one hand and sample control on the other hand, as shown soil samples to pH moderate among the four sites studied, where ranged pH between 7.26 - 6.33 The sample control was pH 8.64 As for water, the results showed basal water sites studied ranged pH between 6.8 to 5.8 which is comparable to Las pH for sample control 8.5, As for connectivity electrical has emerged variation between samples studied and sample control for soil and water and showed samples of soil and water at the site (2) the extent of the variation connectivity electrical them at the sites (3, 2, 1) and which are all higher than in the sample control, with varied degrees connectivity for soil samples between 14, 200 - 2860 Maekerosemins / cm The sample control 2300 Maekerosemins / cm The degree connectivity for water samples 2810 - 2450 Maekerosemins / cm The sample control of water was connectivity 1457 Maekerosemins / cm, for salinity, the results showed an increase in salinity of soil samples and water compared to a sample control ranged salinity in the soil between 8.92 - 1.79 g / l, while a control sample was salinity 1.438 g / l The salinity in the water was between 1.759 - 1.532 g / l The control sample was 0.907 g / l The results showed that the sample at the site (2) the degree of salinity have is higher than the rest of the other samples in soil and water. Results showed high copper for iron in the water was the highest percentage of copper in the signatories (4), (3) 0.05ppm The sample control has, (2.1) compared to a control sample, where he was between 55 - 20 mg / L, while a control sample 3.8 mg / liter, while for water Ekorh has ranged between four samples where Ekorh was water between 12.36 - 2.97 naphthalene The control sample was Ekorh water 2.1 Naphthalene. The results showed that the concentration of iron was high in most plants for copper and cadmium, as was the highest concentration of iron in the plant reeds 24 ppm as was assembled in the root zone of the plant which is within the limits permitted by the World Health Organization while the highest concentration of iron in the area of control of the plant reed it reached 17.5 ppm as it was assembled in the root also Copper was the highest concentration in the plant sergeant cock 0.89 ppm as it was assembled in the root while the focus was in control very few samples The cadmium is 0.1 ppm in all plants is within the allowable limits by the World Health Organization, while in the side anatomical has emerged is a difference between the samples studied and samples of control, as happened increase in the dimensions of the vascular bundles of the leg, as well as an increase in the thickness of the crust in the samples studied compared a sample of control as well as an increase in the thickness of the tissue foundation and a decrease in the number of packets Vascular plant roots as well as increase the thickness of the securities, an increase of pollution in the studied plants compared to a control sample..
