I only know the Pressure/temperature & volume theories that are important in transformation !

Then there is thermodynamics involved on all scales .

eg: Tea boiling , has some flip side that is the reason Japanese have tea tradition and India chai is boiling boiling and boiling !!!

Too much of cooking knocks out the necessary health stuff

Or Almonds when slightly heated is good since it reduces the chances of allergy

Heavy metals are toxic substances and their compounds are used in a large number of applications for their physical and chemical properties. The following are the most prominent heavy metals and their potential effects. In nature there are 35 elements classified as metals, of which only 23 are heavy metals. This label appeared in the 1960s and was used to denote elements And compounds containing high density metals or high atomic mass and have harmful effects on human health and the environment, which made some specialists to change this label to toxic metals. It was initially named heavy metals, most of which had an atomic mass or a higher density than the carbon element, while some other minerals were added to the list because they were similar in their properties to these minerals.

Almost all the time, the transformation process taking place for heavy metals in the environment is that from inorganic to organic forms, most through cycling and the agent of organisms. For example inorganic mercury entering the environment from coal fired plants will initially rent the air environment. From here it shall be scrubbed off the air through the agent of rain and precipitated on the ground, plant leaves, etc. It may then cycle through the agent of water and end up being gobbled up by land animals that graze or aquatic organisms, ultimately end up by being taken up by fish, where it is converted to organic mercury, the fish is eaten by human beings, and cycling continues. In my assessment therefore, re-cycling in the environment, is the most dominant transformation process for heavy metals.
