The seas and oceans are subject to special surveillance given the socioeconomic and ecological interests at stake. Detecting and measuring levels of trace chemical pollution (such as polycyclic aromatic hydrocarbons - PAHs - or pesticides) is the key to dealing with many oceanographic issues. Development of a portable, compact sensor and analyser is fundamental for in-situ studies to complement laboratory techniques.

The goal of the LOUISE project is to design and evaluate a micro component for implementing an innovative, infrared sensor technology called SEIRA-EWS. The SEIRA-EWS micro-sensor will be integrated into a portable instrument and assessed for its ability to detect hydrocarbons and disease biomarkers during field-testing validation. It will enable detection of two compounds whose presence is considered representative - fluoranthene (PAH) and toluene -, detected at levels of 0.1μg/L and 70μg/L respectively.
