| lichen distribution and bioindicator tobacco plants give discordant response: a case study from italy. | epiphytic lichen biodiversity (lb) distribution was evaluated in a 1000 km2 area in tuscany (central italy). in the same area, a survey was performed to monitor tropospheric ozone (o3) phytotoxic effects using tobacco plants (nicotiana tabacum) cv. bel-w3 (o3 supersensitive) and cv. bel-b (o3 resistant) as bioindicators. the lb proved to be negatively correlated with ambient levels of nitrogen oxides, particulate and carbon monoxide, but not with benzene. lb spatial distribution followed a pecul ... | 2003 | 12602630 |
| integrating monitoring networks to obtain estimates of ground-level ozone concentrations --a proof of concept in tuscany (central italy). | prior to 2000 a network of conventional ozone (o3) analysers existed in the province of firenze (tuscany, central italy). between 2000 and 2004 the network was extended to incorporate a newly designed bioindicator network of tobacco plants (nicotiana tabacum bel w3). the objective was to set-up an integrated monitoring system to obtain estimates of ground-level o3 concentrations over the whole study area (3513 km2) in order to fill data gaps and cover reporting requirements. the existing convent ... | 2008 | 18377957 |
