Toxic components of motor vehicle emissions for the spruce Picea abies

Six-year-old Norway spruce trees were exposed for 30 min under standardised conditions to the exhaust from an Otto engine running on lead-free petrol. Gas-exchange measurements in an open system using an infrared gas analyser showed a sudden, severe drop in CO 2 assimilation and transpiration rates....

Description
Summary:Six-year-old Norway spruce trees were exposed for 30 min under standardised conditions to the exhaust from an Otto engine running on lead-free petrol. Gas-exchange measurements in an open system using an infrared gas analyser showed a sudden, severe drop in CO 2 assimilation and transpiration rates. By using filters which absorbed different fractions of the exhaust it could be demonstrated that the toxic effects can be attributed to the NO x fraction.
