English Abstract

Rice crop may be subjected to several heavy metals contamination due to various causes such as contaminated irrigating water, fertilizers containing certain heavy metals and other agricultural applications.

This work was designed to examine several heavy metals (Lead, Chromium, Arsenic and Copper) in rice crop imported from India, USA, Brazil, Thailand, Paraguay and Uruguay in addition to locally cultivated rice.

Rice samples were collected from local markets and subjected to the examination of above heavy metal content using acidic digestive method and heavy metal ions were determined by Atomic Absorption Spectrophotometer.

It has been found that these examined rice crops have shown significant variations in terms of heavy metal content and importing countries where in case of Lead ion, Iraqi rice had the highest mean (19.27 ± 0.25 mg/kg ) content while India 1 showed the lowest (9.51 ± 0.08 mg/kg) mean value.

For rice Chromium content, it was found that USA rice gave the highest (4.02 ± 0.51 mg/kg) mean value and the lowest mean content (0.15 ± 0.02 mg/kg) was detected in the Iraqi rice.

Regarding rice Arsenic content, all examined rice crops had As content varying from minimum mean value of 0.2 ± 0.012 mg/kg in India2 to a maximum value of 0.37 ± 0.021 mg/kg in India1.

For Copper rice content, this study has found the Iraqi crop had the highest (4.50 ± 0.07 mg/kg) mean value while Thailand gave the lowest mean value of 2.66 ± 0.25 mg/kg.
