Ozone experimental protocol

Since 1996, white clover has been used to monitor impacts (for example leaf damage, biomass reduction) of ambient ozone concentrations on crops according to a standardised protocol. In 2008, a new biomonitoring system was developed for ozone, using bean (Phaseolus vulgaris).  This protocol was revised in 2012.  The 2012 standardised protocol for the bean ozone biomonitoring system can be downloaded here.
