The Study of Heavy Elements Level in Medicines plants in some selected Popularity Market of the City of Baghdad

Abstract

The concentration of the heavy and toxic elements accumulated in medicinal herbs was studied. The roots, leaves and seeds were collected. A total of ten samples were collected from selected local markets of Baghdad herbs ( chamomil , Maui roses, coriander, funnel flower, sweet anise, Cumin, cinnamon powder, carnation flower, anisonian or aniseum ,Gujarate tea) which have wide range use by the local people in Baghdad, then determine the concentration of elements (Chrome, Cupper, Lead, Cadmium)was done using atomic absorption spectrophotometry after wet digestion method, the concentration level of the elements has been shown [(0.694-6.8)µg/g of chromium, (2.0-19) µg/g of cupper, (4.7-42) µg/g for Zinc ,(0.168-2.5) µg/g for cadmium, (1.2-8.7) µg/g for lead)], but for Arsenic is lower than detection limit of atomic absorption spectrophotometry less than <100µg/kg for Arsenic, and Chromium, Copper, Zinc, Cadmium, and lead were found to be highest than tolerance in plants, according to the World Health Organization (WHO).

The high percentage of the elements depending on the source of agriculture and methods of assembly, storage, transport and supply in the local markets, was the highest percentage of chromium, lead and copper in the markets of the city of Zaafaraniya, and cadmium in the markets of Sadr City and zinc in the markets of the city of Bayaa.
