Comparison SPMDs and selected abiotic samplers using Gnostic data analysis
The semipermeable membrane device (SPMDs) together with some selected biotic organisms has been applied for monitoring of rivers in the Czech Republic. Some criteria were used for evaluation of the quality of results, mainly: sensitivity and measuring range, homogeneity of results, internal and external consistency and precision. Data were used from monitoring of 19 sampling sites of 15 rivers, realized in 2003-2006. Monitoring data of selected POPs, like polychlorinated biphenyls (PCBs), organochlorinated pesticides (OCPs) were used for the comparison. Robust algorithms maximizing the information of results based on this theory have been developed for many applications, as well as for passive sampling and environmental monitoring.
