سلامة الغذاء و مراقبة محتويات المنتجات الزراعية أمور ذات أهمية كبيرة بالنسبة للمستهلكين، نتيجة للوعي الغذائي، و حفاظاً على الصحة العامة و وقايتها من الأمراض. الهدف من هذه الدراسة معرفة تراكيز بعض المعادن الثقيلة (الرصاص- الكادميوم- النيكل- الكروم)، في بعض النباتات العلفية (البرسيم .Trifolium ssp، النجيل Cynodon dactylon ، الشوفان Avena sativa L.)، و مدى إفرازها في حليب الأبقار في منطقة بانياس في الساحل السوري.
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.
Artificial intelligence review:
Research summary
تتناول هذه الدراسة تراكم بعض المعادن الثقيلة مثل الرصاص، الكادميوم، النيكل، والكروم في النباتات العلفية ومدى إفرازها في حليب الأبقار في منطقة بانياس بالساحل السوري. تم جمع العينات النباتية وعينات الحليب من أربع مناطق مختلفة تبعد مسافات محددة عن مصفاة بانياس والمحطة الحرارية. أظهرت النتائج أن تركيز الرصاص والكادميوم في عينات الحليب من المناطق القريبة من مصادر التلوث كان أعلى من الحدود المسموح بها وفقًا للاتحاد الأوروبي، بينما كانت تراكيز المعادن في النباتات العلفية ضمن الحدود المقبولة. بناءً على هذه النتائج، توصي الدراسة بضرورة مراقبة محتويات المعادن الثقيلة في المنتجات الغذائية لضمان سلامة الغذاء وصحة الإنسان.
Critical review
تعتبر هذه الدراسة مهمة للغاية في تسليط الضوء على مشكلة التلوث بالمعادن الثقيلة وتأثيرها على السلسلة الغذائية. ومع ذلك، يمكن توسيع نطاق الدراسة لتشمل مناطق أخرى وتكرار التجارب على مدار فترات زمنية مختلفة للحصول على نتائج أكثر شمولية. كما يمكن تضمين المزيد من المعادن الثقيلة الأخرى التي قد تكون موجودة في البيئة. من المهم أيضًا النظر في تأثيرات هذه المعادن على صحة الحيوانات نفسها، وليس فقط على الحليب الذي تنتجه.

This study deals with the determination of the quantity of solid dust particles deposed
on the leafs of some trees along Syrian coast and the concentration of some heavy metals
in it (Zn, Fe, Pb, Cu, Ni, Cd, Co, Mn) .Some sites near to human and in
dustrials activities ,
and others near to agriculture activities , and others relatively far from pollution sources
has been selected. The results showed that the quantity of solid dust particles on leafs
trees and concentration of heavy metals in it such as (Pb, Ni, Cd, Co) increasing near the
industrials activities and dense traffic, and decreasing in the sites that relatively far from of
pollution sources. However Cypress trees attach solid quantities more than Pride of china,
following Rever red gum and Blue-leafed wattle and Oleander, and the Palm tree come in
the last.

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
spectrosco
py (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.
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 he
avy 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 .
According to the chemical pollution danger in general and its danger on groundwater
wells in agricultural areas particularly the inhabited ones , the scientific study was
implemented to determine the concentrations of some ions in water wells withi
n the area of
Hraesoon; In addition to, monitoring their changing values which indicate the rate of
chemical pollution in the study area due to existing activities.
The search involves a monthly periodic physical and chemical analyzes in the
invested wells in Hraesoon area , Banias city for a whole year. starting from September
2011 till August 2012 by choosing ten invested wells disterbuted in the area.
The study includes the changing of temperature ,pH, electrical conductivity, and the
group of negative ions (nitrate NO3
-, phosphate PO4
3-, sulphates SO4
2-, chloride Cl-) in
addition to positive ions (ammonium NH4 +, Sodium Na +).
The values of the studied ions have demonstrated a clear disparity in each month for
the samples taken from the same wells, due to the agricultural ,human activities and
climatic conditions that prevailed during the sampling dates.
The recorded results show cases of chemical contamination in the water wells
studied not identical the Syrian standard for drinking water (2011-2012) portend a lot of
health and environmental risks, especially that many of those wells are used for drinking
purposes.
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.
