Another objective is to determine the ill effects of low quality food particularly of artificial colours and other chemicals in the food items.

Total of 2,000 samples each of food items and water would be collected from the identified institutes of different areas of Lahore, Islamabad, Peshawar, Quetta and Karachi. They will be analyzed for colours and other chemicals injurious to health.

The purity test of the colours will be carried out by spectrophotometer and HPLC (Pearson‘s Composition and Analysis of Foods 9th Edition 1989). Other Food Additives as oxalic, acid tartaric acid, rancidity of oil used in frying in some food items will also be analyzed by titration methods.

The results of the survey will be published in the reputed journals and also in the form of small booklets easily available to the people to inform them about the health hazard effect.
