Abstract: A method of providing a consumer of a food product with data regarding food impurities found therein. The method includes providing an analyzer for the food product while providing food impurity concentration data of the food product. The food product is labeled with the identifier which is associated with the food product at distribution. A website is established for receiving the food impurity concentration data and for displaying the food impurity concentration data in association with the identifier. A consumer is provided the opportunity to learn the food impurity concentration data of the food product bearing the identifier by comparing the identifier on the food product with that recited on the website.

Abstract: A device and method for determining mercury levels in a biological sample containing mercury. The biological sample is at least partially dissolved in an acidic solution to release at least a portion of the mercury contained therein. The partially dissolved biological sample is exposed to an anode and cathode under an electromotive force causing at least a portion of the mercury released from the biological sample to adhere to a surface of the cathode. The cathode being exposed to an alkaline metal salt to create a mercury-alkaline metal amalgam. This cathode is then electrically connected to a reference electrode whereby the extent of the amalgam is a measure of the level of mercury in the biological sample.
