QUESTION: How much lead is allowed in plants, soil & water?
01 Apr 2005, New South Wales Australia
I was wondering about levels of lead, cadmium and mercury in plants, soil and water. I am growing certain types of plants that soak up lead from soil and water. I have run samples (1 µg/ml -500 µg/ml) on AAS to determine the absorbance so that I can compare these with the plants after they have grown. I have found that most of the samples are too high and that when a graph is drawn it gives a curve instead of a straight line. I am soon to run samples with smaller amounts of lead. I was wondering how much lead is allowed in plants (soil water) before it becomes unsafe? Is there anywhere I can find out (In parts per million) what is safe, what is borderline and what is extreme? Thankyou |

Dear Charmaine, the levels of lead allowed in plants, soil or water are guidelines only and only relate to edible parts of plants.
Lead mg/kg
I hope this helps. I'd be glad to add your final research article to our
library. Please email it when complete. |
