摘要: The purpose of the study was to compare three recent Life Cycle Impact Assessment (LCIA) models in prioritizing substances and products from national emission inventories. focus on ecotoxic human toxic impacts. aim test model output against expert judgment chemical risk assessment. An inventory collected for Finland describing year 2005. included publicly reported emissions air water it complemented by tributyltin, benzene, pesticides research papers statistics. were characterized with LCIA models: IMPACT 2002+, ReCiPe, USEtox priority identified. results connected an environmentally extended input–output supply chains. A comparison made two integrated assessments status exposure Baltic region. assessed presented very different priorities. In ecotoxicity, IMPACT2002+ highlighted heavy metals while ReCiPe focused tributyltin. assessment identified both groups. toxicity, organic pollutants mainly metals. can be used setting control consumption based analyses. However give differing prioritizations so care must taken selection. studied differed mostly which are bioaccumulative. Further studies including bioaccumulation impact recommended.
