Can passive sampling devices provide more useful data than discrete samples?

Passive Sampling Devices (PSDs) are devices that can be used to monitor both organic and inorganic compounds. They typically contain a receiving phase with a high affinity for the compound of interest, are usually deployed for a few weeks, retrieved and analysed for the compound of interest. The project has collated information from manufacturers, suppliers and users on available PSDs and their current use.

The conclusion was that there is a clear potential for the use of passive samplers of the integrating type for monitoring of both inorganic and organic compounds. PSDs are potentially most useful:

*for long-term trend monitoring;
*for investigative work tracing a source of pollution; and
*to be used instead of biota in environmental monitoring.

The benefits of catchment management are widely recognised within the water industry. Understanding the delivery pathways of sediment, pesticides and nutrients, and the timing of diffuse pollution is a key challenge to achieving drinking water standards and improving the quality of watercourses.
 
The research has developed new approaches to catchment management, looking at land in a different way using a combination of remote sensing imagery and ground-based surveys. In circumstances where methods such as walkover surveys may not be appropriate, for example in upland and larger catchments, remote sensing tools offer an alternative way of identifying field scale solutions. The use of imagery is also very effective when engaging with landowners.
 
An approach has been developed which starts with readily available imagery from satellites and aerial platforms to identify potential risk in a catchment, and which then focuses in on sub-catchment and field scale solutions that require more detailed imagery.
