Paper II presents a scoring method to prioritize organic chemicals of emerging Arctic concern for their potential to fit a set of four exposure-based hazard profiles.
We used in silico estimates of physicochemical properties and multimedia models to calculate hazard metrics for persistence, bioaccumulation and long-range transport potential, then we synthesized this information into four exposure-based hazard scores of the potential of each AMAP chemical to fit each of the POP, vPvB, APC and WPC exposure-based hazard profiles.
APCs and WPCs are chemicals that are mobile in air and water, respectively, and that contaminate the environment in a poorly reversible manner due to their persistence. These models can be used in high-throughput exposure assessment studies, passive sampling experiments, and models of emissions, fate and transport of chemicals. There are no ingredients present which, within the current knowledge of the supplier and in the concentrations applicable, are classified as hazardous to health or the environment, are PBTs or vPvBs or have been assigned a workplace exposure limit and hence require reporting in this section.

Screening criteria for PBTs/vPvBs
Our results show that scores in the four exposure-based hazard profiles provide complementary information about the potential environmental exposure-based hazards of the AMAP chemicals.
Reviewing applications can be fun and only takes a few minutes. A report that reviews Arctic contaminants that are not currently regulated as persistent organic pollutants POPs under international treaties was recently published by the Arctic Monitoring and Assessment Programme AMAP. Patents, Trademarks, Copyright Law: Latvian PRO pts in category: We evaluated individual chemicals mentioned in the AMAP report according to hazard profiles for POPs, very cpvbs and very bioaccumulative vPvB chemicals, and two novel and vlvbs hazard profiles we derived from the vpvhs boundary threat framework.
English term or phrase: The in silico methods developed in this thesis can be applied to conduct screening-level exposure assessments using only chemical structures as a starting point. Close and don’t show again Close.

The KudoZ network provides a framework for translators and others to assist each other with translations or explanations of terms and short phrases. Paper I delivers screening-level models to predict partition ratios of organic chemicals between polymeric materials commonly found indoors, and vpvb air and water.
Paper III elucidates the relationship between the elemental composition of these chemicals and the exposure-based hazard scores, and presents a strategy to disentangle overlaps among the four exposure hazard profiles by categorizing chemicals according to the vpvbss coverage of profiles they best fit.
This thesis describes the development of a set of in silico methods to identify and prioritize chemicals with high exposure potential that are currently not subject to national or international restrictions.
