Research into and diagnosis of environmental change prior to the introduction of bioindicator methods were linked primarily to apparatus. Drawing attention to the reactions of organisms sensitive to that change and using them in environmental quality control have opened new opportunities for development of a new scientific discipline, known in the literature as bioindication. Bioindication combines several scientific disciplines, including biology, broadly conceived geography, and chemistry. It thus combines in a comprehensible manner apparatus-derived measurements (chemical analysis results) and areas of bioindicator exposure (situation and distance from the emitter), translating these parameters into bioindicators' anatomical and morphological reactions. The development of bioindicator methods progresses rapidly, and - as is usually the case under such circumstances - it is difficult to ensure that they are transparent and that no chaos ensues. In view of the above, it seems necessary to embark on a discussion of these issues and consider compiling lists of most applicable indicator organisms for examination of particular environmental toxins in particular environments.
