Determination of the Presence of Heavy Metals in Raw Bovine Milk in the Parish Bilován, Province of Bolívar (Ecuador)

Abstract

The objective of the research was to determine the presence of heavy metals in raw bovine milk, which was carried out in the parish of Bilován in the canton of San Miguel (Ecuador) considering that the presence of said chemical elements in milk leads to a damage to the health of the animal and subsequently to the consumer. The research was carried out with a population of 15 female cattle obtaining 100 mL of sample. A parameter to consider was how the consumption of offal from the corn harvest influences when estimating the influence of the various agrochemical products used in the crops. After the analysis, with respect to the number of APU they are in a range between 1 to 5 AUP, in addition, that 1 to 5 cows are destined for the production of milk, where 66.67 of milk is destined for the production of cheese. On the other hand, in the type of forage used, there is a certain similarity between kikuyo and corn crop waste, 66.66 of those consulted say that they apply pesticides only once during cultivation, however, the rest of those consulted say that they apply three times. Through the analysis of metal residues such as Pb and Cu; in Pb was found in a concentration of <0.02 mg/Kg; and Copper of 0.38 mg/Kg. In conclusion, the concentrations of lead and copper do not exceed the maximum permissible limits in the milk samples analyzed.
