ABSTRACT
To prevent contamination peaks that reach drinking water produc-
tion, inlet points for surface water are monitored for the presence
of contaminants. The currently applied routine chemical analysis,
albeit useful in many ways, gives no indication of the toxicity of
pollutants and may miss unknown compounds that are harmful at
low levels. Biomonitors, such as algae and daphnia, do detect certain
toxic compounds timely [1]. However, many harmful compounds
that are very relevant from a human perspective, such as genotox-
icants, cannot be measured by biomonitors. What is missing is an
online system that sensitively and in real time detects compounds in
water that are potentially harmful for human consumers.
