This is supported by the Global Environmental Assessment and Information System (GENASIS) that utilizes data from national and international monitoring networks to obtain as-complete-as-possible set of information and a representative picture of environmental contamination by POPs. Institute of Biostatistics and Analyses (IBA) operates the System for Visualizing of Oncology Data (SVOD) for cancer epidemiology in the Czech Republic for data from Czech National Oncology Register. The synthesis of existing POPs pollution monitoring databases with epidemiological data is required for identifying some effects of POPs on human health. This task requires new, rich, data and services discovery capabilities within the bodies of knowledge available, which are discussed in the paper. IBA and RECETOX anthropogenic impact studies requiring data discovery from a multitude of monitoring networks and resources. The FP7 project ``TaToo -- Tagging Tool based on a Semantic Discovery Framework'' are setting up a semantic web solution to close the discovery gap that prevents a full and easy access to information resources on the web. The use of TaToo tools together with GENASIS and SVOD is presented for the discovery of anthropogenic impact in several examples. \itemrv{~} \itemcc{} \itemut{} \itemli{doi:10.1007/978-3-642-15825-4\_65} \end
