Dear Azra.

I would suggest use of ICPMS and technique should not be very complicated for experienced ICPMS user. You may also want to consider distribution of toxins such as where are they located, skin, seeds, flesh etc. I know that colleagues at my uni (University of Canberra) have been doing these type of analysis for some time.The closest to "home" that I can think of are guys at University of Belgrade.

Pozdrav svima u prelijepom Sarajevu.

Thank you very much for your reply, I will try to use the knowledge counterpart in Belgrade. I am especially pleased that our scientists are successful all over the world, and among them you Nenad.

Kind regards from Sarajevo

Biochemical analysis of heavy metal toxicity and its removal would improve the sell of tomatoes. Heavy metals are consumed by the plants during its development and can be neutralized by some genes and proteins that are manufactured inside the plant. Being biotechnologist, we emphasize more on the molecular aspects. These genes and proteins may also be introduced externally in the tomato plants. We need to look for heavy metal tolerant genes from plants that grows naturally in heavy metal rich soils and then introduce it in our desired plants.
