It seems unlikely that we can achieve an understanding of chemical planetary boundaries through a reductionist approach based on the study of individual chemicals. This would generate an endless quest for more data, while we are in need of a representation of chemical pollution that makes the problem more tractable for the purposes of decision support. While chemical pollution meant as a cumulative phenomenon is still difficult to handle, there is a wide perception that impacts of chemicals, as well as other co-stressors, might be addressed effectively in an integrated perspective, according to the logics of the relative risk model (RRM). Geographic information system (GIS)-based models often consist of a simple sequence of easily understandable operations conducted on maps, and the inputs and results can easily be visualized as maps themselves. In this way, the specification of model used, and input and output data can be realized.
