The main programme of IPSW 2011 will comprise invited and contributed talks, poster presentations, panel discussions and workshops. The scientific focus of the meeting will be on the use of in situ passive samplers for environmental monitoring and risk assessment. Amongst other subjects to be discussed will be the use of passive samplers in regulatory monitoring. With the continued maturation of passive sampling, this meeting will also offer more ‘hands-on’ discussions to tackle specific practical applications of these tools. Topics related to classical and robust approaches for data evaluation will be discussed.
