Abstract

The present study estimate the levels of sulphur and fluorine in buffaloe's milk and their products in three localities (Manqua bade, El-Tawabiya and El-Akrad) surrounding the superphosphate factory in Assiut governorate. Related elements as calcium phos phorus, sodium and potassium were also investigated.
The physical examination (colour and flavour) revealed that all examined milk samples were within normal limits. The chemical examination showed a significant decrease in chloride and fat perecentage. Statistical analytical results indicated a significant
• increase of sulphur (at 0.01 level) in milk, whey, cheese and yoghourt of the three examined areas. Moreover, a significant elevation of fluorine level was recorded in all milk samples and their products, accompanied with significant depletion in both calcium, phosphorus, and sodium, and increase in potassium level.
