Estimating the level of lead in the eucalyptus leaves

The importance of research being deals with the problem of significant environmental concern the pollution of the plant , soil and air component lead as a result of rapid industrial development since the twentieth century . Was selected Eucalyptus for several considerations , including the widening spread and being one of the bumpers wind that might ease the arrival of pollutants in the atmosphere to regions far geographically . was selected several sites of Homs in order to examine the content of the soil and leaves Eucalyptus from a bullet was found that the concentration of lead element in the plant was caused by air pollution , where not shown the existence of relations clear engagement between the content of soils of lead ( for a total and disposable absorption ) with the lead content of the plant . Ranged concentration of lead overall in the soil between 1.98 ppm ( through Homs - peaceful ) and 72.47 ppm ( Highway Tartus in the south ) , and the average of 4.857 ppm, did not exceed the concentration of lead in the samples studied , both inside the city or outside the normal limit and values lead stainless absorption in the soil ranged from ppm (19.02- 0.02), ranged lead concentration in the plant between 2.01ppm and 10.35ppm and this concentration of lead element within the permissible limits but with time become toxic showing a lack of liaison relationships between the component lead either in the soil or plant with the CaCO3 and Active lime. Finally we can say that the contamination of the plant within the city is higher than elsewhere because of the busy traffic . Add to that the increase in soil lead content available led to increase the concentration of lead in Eucalyptus,leaves

Comparison between the concentrations of some pollutants in drinking water from distribution system and bottled water

Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some taps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.

Study of Some Indicators of Water Quality in Lattakia Dams

This study aimed at determining some indicators of water quality in Lattakia dams within ten years (2002-2011).The indicators(pH, Electrical conductivity,Total Hardness, ca Hardness, Mg Hardness, Alkalinity, Phenol Alkalinity) in five dams (Balloran, 16 Tishreen, Al-thawra, Al-safarkia and Al-hweez) were studied. The resultsshowed thatpH, Electrical conductivity,Total Hardness, Alkalinity, Phenol Alkalinity, were within the allowed limits according to Syrian standards for drinking and irrigation water and which indicate the presence of pollution water sources.

Study of some physical and chemical parameters of the Addelbeh Valley water and groundwater in the area of Tartous Cement Factory

This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.

Study of some quality indicators of drinking water in some drinking water resources in Syrian coastal area

Water sources in Syrian coastal area have a great importance due to the variety of the sources and the urgent needs to water for drinking and irrigation. Therefore great efforts are made to protect water sources from contaminants. This research aimed to study some contaminant indicators in some drinking water sources in the Syrian coastal area. The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and zinc in water samples taken from five sources of water distributed from north Lattakia to north Tartous. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their relative purity and contaminants little reach.

Isolation and identification of Pseudomonas pachastrellae, Micrococcus brunensis bacteria from soil polluted by petroleum

Two bacterial species were isolated from petroleum hydrocarbon-contaminated soil. The isolates were characterized based on their gram reaction characteristics, morphological and biochemical properties. The results showed two bacteria isolated the first isolated: gram negative short rod, urease and nitrate reduction test showed a positive result , and glucose test showed positive result. And the second isolated: gram positive cocci, gelatin and Citrate utilization test showed a positive result , and maltose, mannitol test showed negative result. They were then incubated at (37) ° C for (48- 72) hours. This is based on comparison of results with Bergey Manual of systematic bacteriology. The isolates were identified to be: Pseudomonas pachastrellae (X1) Micrococcus brunensis (X2).

Food safety and monitor of the contents of agricultural products are matters of great importance for consumers, as a result of food awareness, public health and disease prevention. The aim of this study is to know the concentrations of some heavy metals (lead - cadmium - nickel - chromium), in some fodder plants (Trifolium ssp., Cynodon dactylon., Avena sativa L.), and the extent of its secreted in the milk of cows in the area of Banias on the Syrian coast.

Determination of the contents of some trace of Heavy metals (Cu, Cd, Pb) in marine algae from the coast of Banias

The study focused in this research to determine the trace of some heavy metal elements (Copper Cu, Cadmium Cd, Lead Pb) in some types of marine macroalgae scattered on the shore of the city of Banias during 2014, using atomic absorption spectroscopy (technology flame Flame- AAS). The results indicate that the concentrationsofeach of Copper, Cadmium and Lead have a link with macroalgae types, sampling sites from direction, and Source of pollution on the other hand; it was observed that the accumulation of heavy metals in both of Sargassum vulgare (browen algae) and Enteromorpha linza (green algae) was more than red algae. Copper concentration ranged between 1.291 ppm and 11.716 ppm in the studied species, Reaching the highest value in the Enteromorpha linzaalgae and the lowest in Sargassum vulgarealgae, the highest value of Lead element was (59.354 ppm) in Enteromorpha linzaand the lowest value of it was (6.46 ppm) in Ulva fasciata, While the highest values of the element Cadmium recorded (10.457 ppm) in Enteromorpha linza and the lowest (0.666 ppm) in Ulva fasciata.

Application of the Water Quality Index (NSFWQI) on the Al-Sain Lake

This research aims to evaluate the water quality of the Al-Sain lake which feeds mainly the Lattakia city and a part of the Tartous city of drinking water purpose. In this paper, we study a group of physical and chemical factors for the water of the Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were taken from four different locations according to the program approved by the concerned staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water supply point, irrigation point, southern spring observatory), and we calculated the quality index for drinking purposes using US approved methodology of National Sanitation Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH, BOD5, temperature, phosphate, nitrates, turbidity, and total solids). The research result showed that the classification of water quality was good in all four monitoring points during the years 1991 and 2004, noting a significant improvement of the quality in 2004, and decreases slightly during the years 2007 and 2011 for monitoring points in the Lattakia water supply and irrigation points, but water quality still keep maintain a good classification, while the quality of the water goes down within the threshold of middle classification for the Tartous and southern spring observatory monitoring point.
