Against threats to populations by water pollution, it is critical to remotely, continuously and unambiguously identify and quantify pollutants in surface and ground water. This fast evolving field shall benefit increasingly from optical technologies. We propose a tentative review of the state of art and some promising ideas.

Arsenic (As) is one of the most toxic contaminants found in the environment and especially in water. The World Health Organization decrees an As concentration less than 10 µg/L (10ppb). Established laboratory method is mass spectrometry. This technique is costly and time-intensive [1]. Other methods for As detection in water are in state of...

Arsenic is one of the most toxic elements present in the environment, especially in water. The World Health Organization (WHO) recommends a maximum concentration of arsenic in drinkable water of 10 μg/l (10 ppb). Sensors implementing Surface Enhanced Raman Scattering (SERS) can detect chemical species at low concentrations. The aim of this...
