I am trying to link the presence of heavy metals in drinking water sources or the biomagnification of these metals up the food chains for example when waste waters are used in irrigation and the plants take the metals up or when waste water mixes with aquatic ecosystems like rivers and lakes and fish take them up..and then there is the risk of humans consuming the contaminated fish or plants. could these processes be linked to the rising cases of cancer? how can such a research be designed?
You can measure the dose of heavy metals in tissues of plants, fish and animals that drink the water or who eat that water plants and that fish.
If you study the water from the tap, you can give it to some animals (lab mice) and look at their tissues.
I'm not sure about human level (human tissues). Using medical statistics is a good idea.
Refer to the works of John Oyari University of Nairobi Kenya. He has enough experience in and skills in the analysis of heavy metals particularly in the fresh waters of Lake Victoria
Okay..thanks Amuka Omari..I will..and thanks too Anna for that particular insight you have given me..very interesting..I will think along those lines
Bio-magnification is an obvious phenomena and will occur as in the reverse of pyramid of numbers such the at end of the chain the organism will have relatively higher concentration of the heavy metals as compared to the recipient organism.
