The analysis of chemicals such as CECs is of critical importance to protect natural environments and public health. Large numbers of CECs have been investigated in surface waters across the world, however many of these studies have focused on a catchment approach . Several nationwide studies of CECs in multiple rivers have been conducted . In comparison, international campaigns from multiple geographic locations are far less common, with only a handful in literature (Table ). Unfortunately, multi-target, trace analysis of chemically different CECs in environmental waters requires highly sophisticated instrumentation and well-trained specialists. As a result, there is very little published literature on the presence and fate of CECs in many regions and countries worldwide. Under representation has been reported for some Asian, African and South American countries (aus der . Hence there is no incentive to influence regulations on national and global scales. One of the key issues lies in current inability to collect and transport water samples over long distances without compromising sample integrity during transport from the sampling point to the analyzing lab, often based in different, cities, countries and continents. Therefore, there is an urgent need to develop in-situ sample preparation approaches that will allow for rapid stabilization of analytes immediately after sample collection and during transport (up to week or longer).
