In the centre of environmental chemistry is to understand processes in the environment and in biota. There is a strong interest especially to metal and metalloids due to their toxicity and essentiality. This lecture will illustrate that it is important to determine the molecular form of those elements in order to understand why arsenic or methylmercury are taking up into the plants, accumulate into the rice grain and how mercury is biomagnified in the marine food chain and how mercury forms nanoparticles in the brain of pilot whales. In most cases new analytical methods needed to be developed to identify and quantify the most important elemental species. It will be shown that this year for the first time speciation analysis was implemented into EU legislation. Find out what this is all about.
