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.
Welded joints corrosion phenomena for some kinds of stainless steels and nickel alloy was studied in polluted phosphoric acid 37.7%H3Po4 using electrochemical techniques like Tafel polarization. Corrosion rate of base metal and weld metal had calcu lated & compared among these alloys. Laboratory Test results showed the change in both corrosion rate and corrosion current densities (Icorr) for tested alloys, and there is a clear difference between base metal and weld metal in most of tested alloys , which lead to high corrosion rates of welded joint, and change in its properties then gets out of service in some service conditions. The stainless steel 904L has low corrosion rates and low difference in corrosion rates between base metal and weld metal, so it may be the most suitable alloy, among all the studied alloys, for exploitation in polluted phosphoric acid 37.7%H3Po4 produced at the General Fertilizer Company in Homs city.
The concentrations of copper (Cu), zinc (Zn), nickel (Ni), lead (Pb), cadmium (Cd) in dead and live honeybees were determined by using atomic absorption spectrophotometry. The samples were collected from beehives of stationary apiariessituated in five different locations of Latakia; Qardahah (Asitamo), Haffeh (Dabba), Jableh (Snouper),Latakia city (Al-Ramel Al-Shamali\ Autostrade of Al-Jomhouria) and Eastern Entryway to Latakia (behind Al-Jood factory) , during the spring and autumn in 2014.
This study aimed to estimate the level of air pollution in some portable heavy metals in dust quarries by needles of Pinus brutia Ten. as biomonitor In site of Kfardabeel Stand- Jableh. The samples of dust and leaves were collected at the end of Ju ly in 2016, Atomic absorption spectrophotometer was used to determine the amounts of Lead, Zinc, Nickel (ppm, dry weight). The average of accumulated metals in the needles were estimated: (Pb= 45.57 ppm, Zn= 13.64 ppm, Ni= 7.64 ppm), while their amounts in the dust were done as following: (Pb= 66.1 ppm, Zn= 15.8 ppm, Ni= 19.6 ppm). The results showed that the studied site is polluted with Pb and Ni whereas Zn is in the natural range. a strong correlation between heavy metals amounts in the needles and their amounts in the trapped dust (r= 0.98) was detected, also regression equations have explained the variations in accumulation of studied metals in relation to the accumulated dust on needles as following: 40% Pb, 40% Zn, 20% Ni. Consequently results confirmed the possibility of detecting the atmospheric Pb, Zn, Ni pollution in the studied site using P. brutia Needles as a biomonitor.
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.
The aim of the study was to study the ability of the leaves of the figs (Ficus retusa L.) and (Phoenix dactylifera L.) in the city of Tartous to accumulate the lead elements (Pb), nickel (Ni).
