Chapter 9: Ambient Ozone Alternative Monitoring and Biomonitoring with Higher Plants

Biomonitoring is a biologically meaningful method for monitoring environmental quality by assessing the impact of environmental changes on living organisms. Over the last decades, selected ozone-sensitive plant species have been used as ozone bioindicators. We present here the three most important bioindicator species: (i) the Bel-W3 and Bel-B tobacco system, (ii) the white clover (NC-S and NC-R) system and (iii) the snap bean (R123 and S156) system.
