Table 1 Fields of application of suspect and non-target screening in environmental monitoring
From: NORMAN guidance on suspect and non-target screening in environmental monitoring
Suspect screening | Non-target screening |
|---|---|
Identifying expected contaminants in the environment for future monitoring | Identifying unknown or unexpected contaminants in the environment for future monitoring |
Obtaining big picture of pollution by monitoring of large numbers of suspects, e.g., REACH chemicals, NORMAN SusDat | Identifying unknown chemicals from spills, specific emission sources and other events, such as stormwater run-off, industry outflow |
Specific view on substance class related to specific chemistry, origins or usage, e.g., bisphenols, per- and polyfluorinated compounds, pesticides | Identifying causative chemicals for adverse effects observed through bioassays by effect-based tools including effect-directed analysis |
Detecting exposure-relevant chemicals based on modelling approaches (emission, fate) in combination with chemical databases | Identifying causative chemicals for adverse effects observed in ecosystems by ecological monitoring |
Detecting TPs or (disinfection) byproducts reported in literature or predicted by QSAR | Identifying new persistent and bioaccumulative compounds from multimedia and biota monitoring |
Spatial monitoring along, e.g., river stretches | Spatial monitoring along, e.g., river stretches |
Trend monitoring over time at one site | Trend monitoring over time at one site |
Retrospective screening of emerging suspects in stored raw data to determine extent of previous contamination | Retrospective screening of unknown chemicals / masses of interest in stored raw data to determine extent of previous contamination |
