摘要：The concentration of 27 elements of mineral and toxic heavy metals have been determined in 55 samples ofcanned and corresponding fresh food, for comparison. These samples (30 of them is canned food and the rest is freshfood) were collected from different local markets of western district of Saudi Arabia. For reliable, accurate and precisemeasurements, Inductively Coupled Plasma - Atomic Emission Spectrometer (ICP-AES) has been used to quantify thelevels of the studied metals in the food samples after digestion using microwave system. The results obtained showedthat, the mean ranges of the elements analyzed in (mg kg-1) between the fresh and canned food are as follows: Fe (34.35– 164.1), Al (6.63 – 41.14), Mn (11.73 – 17.95), Pb (2.31 – 7.11), Zn (24.14 – 26.76), Cu (6.22 – 8.03), Ca (1611 –8557), Mg (1669 – 1206), Na (9918 – 23787), respectively. Some of the measured values found, not only relativelyhigh in canned compared to fresh food samples, but also exceeds the international tolerance levels. The monitoring ofmineral and heavy metals in fresh and canned food samples is vital important challenge to control and improve the foodindustry strategies.
