Determination of Heavy Metal Levels in One Portion of Some Fruits and Vegetables by ICP-MS Method
Marmara University, Turkey
Aims: This study was carried out to determine the heavy metal levels in one portion of some fruits and vegatables thats old in different local markets of Istanbul and to examine the effects of the results on human health.
Materials and Methods: This study was conducted in March 2017. Apple as fruit; carrot, potato and spinach as vegetables are selected. Samples were taken from the local markets in Kartal, Maltepe and Sarıyer districts. The analysis of the samples was carried out by Agilent 7700 ICP-MS instrument in Central Laboratoryof Yıldız Technical University. The calculations have been done on the net amount, which obtained by removal of the calculated waste amount of the analyzed nutritions from the gross one gram of portions.
As seen in table above, arsenic content in the spinach was found to be highest as well as cadmium and lead contents. Arsenic, lead and mercury contents found to be the lowest in potato per portion.
Conclusion: According to Turkish Food Codexand JECFA(Joint Expert Committee for Food Additives) limits, cadmium and mercury are below the limits and lead datas are above the limits. There is no limit for arsenic. To make assessments on human health, there is a need for more studies in this area.
