Impact/Purpose:
These suspect screening and data mining approaches can identify novel exposure sources that can be further investigated for inclusion in exposure assessments or mitigation efforts.
Description:
A near-field exposure pathway of interest concerns consumer products that are manufactured using recycled waste. The chemical composition of a recycled product can be influenced by the original composition of the source material and any potential additions that occur during the recycling process, intentional or not. Non-targeted (NTA), or more specifically, suspect screening, analysis can provide a high-throughput method for rapidly identifying these chemicals. Data mining techniques can be applied to find clusters of chemicals that either co-occur in particular products or have similar functional use, in an attempt to identify novel exposure sources. These clusters can later be prioritized for confirmation using chemical standards.
