A comparison was made between Papaver and Malva plants in Aljaouba area between the grown plants on the roadside (0-3 m) , and also50 m far nearly exposure to the pollution . The study in volves a comparison analyses for the concentrations of some heavy metals in the tissues of two studied plants ,during the period April-July 2010 , in order to show the effect of the increased number of vehicles on the concentrations of these metals . The analyses showed that a change of the mineral content of some heavy metals in the tissues of the leaf, according to its far and near to the road , where concentrations of Pb , Cu , Fe , were decreased in various rates , according to the faring stepwise from the road . It also noticed an increasing inthe concentrations of these elements by increasing number of vehicles . The results showed also that plants , which are growing on the roadside , are affected by the pollutants emitted by exhausts , where plant length , leaf weight , leaf area , water content were decreased . The Pollutionalso affected the reproduction and production structures , where the number of flowers and its weight , distances of petals , number of stamens , number of fruits and their weight were decreased .

This study has been conducted to identify the levels of heavy metals (lead, cadmium, nickel, cobalt, copper, iron, manganese, and zinc) in the following spices: Nutmeg, turmeric, cinnamon, ginger, cardamom, nigella sativa, black pepper, cumin, coriander, curry, and mixed spices.
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.
This study was conducted to identify the levels of heavy metals (lead, cadmium, mercury, nickel, copper, iron, zinc) in the following processed local and imported meat: Sardine (canned full), Tuna (canned chunks), Hammour (frozen full), Euphrates Fis h (frozen full), fish produced at Qattinah Lake in Syria (frozen full) , lamb (frozen ground), beef (frozen ground), lamb sausage (frozen full), beef sausage (frozen full), sausageproduced in Netherlands (frozen stuffed), lamb liver (frozen full), broiler chicken liver (frozen full), broiler chicken (frozen full), chicken mortadella (canned), beef mortadella (canned), chicken mortadella (canned) produced in Netherlands. Heavy metal concentrations were identified in the samples of the studied meat by atomic absorption spectrometer. The concentrations taken in the wet weight measured in (ppm) were as follows: lead values range between (0.1–5.61),cadmium(0.01–2.02), mercury (0.14 –79.01), nickel (0.11 - 0.82), copper (0.24 – 6.89), iron (1.01 - 91.03), zinc (8.14 - 45.5). It was noticed that in some of the studied samples of the imported and locally-processed meat the levels of lead, cadmium, mercury, and nickel were above the levels permitted by WHO (World Health Organization) and by FAO (Food and Agriculture Organization).While the concentrations of copper, iron, and zincwere belowthelevels permitted.
In this work we study the kinetic of Catalase and Guaiacol peroxidase and the effect of : pH, temperature, enzyme concentration and substrate concentration on the activity of these enzymes in the mesocotyles of Zea mays ( Ghoto82 ) 6 day old.
This study deals with identifying some heavy metals (Pb,Zn,Ni) concentration in the recycledsewage in Latakia Countryside which is resulting from three treatment plants distributed over (Hebbeit, Al-Harah, MarjMoairban),2011.This research uses the El ectro Thermal Atomization-Atomic Absorption Spectrometry (ETA-AAS) technique in determining of heavy metal elements mentioned above. This research shows a higher concentration of Zn-element (2.798 mg/L) in all treatment plants and in all seasons compared with the concentration of other elements, while Ni and Pb have recorded low concentrations (0.351, 0.243) mg/ℓ, respectively. The statistical study has demonstrated that there is a correlation varying from positive high to positive low, and sometimes to negative highs and lows, this gives clear indications for resources of pollution.
