Material type: materialTypeLabelBookPublisher: 2016Description: 51p.Subject(s): Food Safety and Control | Department of Food Science and Human NutritionDDC classification: 2542-T Dissertation note: Food safety is serious issue now a days in Pakistan as many food borne diseases occur due to consumption of unsafe local beverages and soft drinks. Use of polluted water in locally produce beverages and juices without any treatment liable to cause diseases. In summer beverages are commonly used to quench the thirst in Pakistan due to hot weather. Excessive use of such type of drinks cause different diseases like hypertension, gastrointestinal problem, liver and kidney failure, and also carcinogenic. So in this project, concentrations of various heavy metals including Lead, Cadmium and Iron were determined in local beverages (roadside vendors) from different public places of Lahore, Punjab Pakistan. Total 200 samples of five different types of beverages were collected from ten different public places of Lahore. 50 samples were collected with the interval of 15 days. Sampling were repeated three times from four different road side vendors of same areas. The analyses will be carried out using atomic absorption spectroscopy (AAS) with electro thermic atomization in graphite furnace for the determination of the total content of lead (Pb) iron (Fe) and cadmium (Cd). The concentration of the digested soft drink samples will be derived from the regression equation and the samples will analyzed in duplicates. Present study was conducted at the Department of Environmental Sciences, UVAS Lahore for the duration of four months. The data thus obtained from this research was evaluated through descriptive statistics. And the results of concentration of lead, iron and cadmium are not significant and not according to Standards of Pakistan.
