Life cycle analysis applied to analytical methods for the detection of waterborne pathogens

The use phase was identified as the major contributor to the CFP along the whole life cycle of the new analytical products. Up to 66% reduction was calculated for the Aquavalens analytical methods in relation to conventional methods when pathogens from the three groups (bacteria, protozoa and viruses) were analysed. The parametric variability calculated through Monte Carlo simulation showed the effect of different praxis and management during sampling and laboratory work. The collection of the samples, and specifically the transport to and from the sampling points to the laboratory, was found to be the most determinant contributor in the total CFP. Besides, the analysis considered alternative scenarios for the type of vehicle used in the sampling transport and different electricity production mixes.
