Blooms of blue-green algae in freshwater lakes and reservoirs can produce toxic cyclic peptides called microcystins that sicken swimmers and people who drink the water. Researchers have now demonstrated a vibrational spectroscopy method that could eventually allow a quick test of whether these blooms are toxic. (Environ. Sci. Technol., DOI: 10.1021/es200255y)

Environmental researchers have several techniques to screen for the toxins but none . . .
