تم دراسة الأثر المتبقي لعنصر الرصاص في حليب الأبقار بمحافظة طرطوس. و استخدم لذلك (135) بقرة حلوب بمواسم مختلفة و من مزارع مختلفة (مزرعة أبقار زاهد, مزرعة أبقار معمل الاسمنت ومزرعة أبقار مصفاة بانياس), و هدفت الدراسة إلى تحديد نسبة الرصاص بدقة في حليب الأبقار بثلاثة مزارع, و لذلك جمعت عينات من الحليب, التربة, الماء و العلف و تم تقدير عنصر الرصاص فيها.
the residual lead effect in cows milk was studied in the Governant of Tartous. For this end,135 dairy cows in different milking seasons and from three different farm stationes (Zahed cow station,Cement factory farm station and Banias refinery cow station) were used. The objective of the study was to accurately determine lead concectrations in cows milk in the three different farms. Samples of milk,soil,water and feedstuff were collected and lead concentration was determined then statistically analyzed.

يعد الرصاص احد العناصر المعدنية الثقيلة والخطيرة بالنسبة للانسان حيث تقدر نسبة الرصاص المسموح بها في الحليب PPm 0.02
This study aimed to study the economic efficiency of producing
biogas from manure dairy cows, through cost and revenue account,
using some of economic indicators.
A study of chemical composition of woman's milk has been
made and compared with cow's milk in the province of Homs.
The findings of this study show that The total value of the solid
material in cow's milk is (12.26 ± 1.2%). It is approximately
eq
ual to woman 's milk content of the total solid material which
is (12.11 ± 0.09%).
The woman 's milk content of mineral elements is (02% ±
001%), while the cow's milk content is (0.71 ± 0.14%).
For the value of fatty material in the mother's milk, it is (3.5 ±
0.02%) and this is almost equal to cow's milk content of the
same material which is (3.4 ± 0.05%).
The cow's milk content of protein is equivalent to (2.92 ±
0.019%), whereas cow's milk content is equivalent to ( 1.25 ±
0.009%).
The value of calcium in the mother's milk is (32 ± 4.3 mg), and
this is significantly lower than the value of the calcium in cow's
milk, which is (118 ± 8.2 Mg/ kg).
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.
Soil water erosion is a major factor of land degradation in the coastal slopes of Syria, and in the long run represents a real threat to the environment and natural resources such as soil, water and vegetation cover.
