“…As a result, the conversion of forests to pastures in the tropics might decrease isoprenoid emissions. However, grasslands also emit significant amounts of other BVOCs, although they tend to be oxygenated compounds, such as ketones and aldehydes, which quickly dissolve in water and are deposited by rain [31]. Other land cover changes because of agricultural land abandonment and subsequent forestation or forest plantations of, for example, Populus, Eucalyptus or Pinus, which are major emitters, might greatly increase BVOC emissions.…”

With significant water savings and low maintenance requirements, artificial turf is increasingly promoted as a replacement for natural grass on athletic fields and lawns. However, there remains the question of whether it is an environmentally friendly alternative to natural grass. The major concerns stem from the infill material that is typically derived from scrap tires. Tire rubber crumb contains a range of organic contaminants and heavy metals that can volatilize into the air and/or leach into the percolating rainwater, thereby posing a potential risk to the environment and human health. A limited number of studies have shown that the concentrations of volatile and semivolatile organic compounds in the air above artificial turf fields were typically not higher than the local background, while the concentrations of heavy metals and organic contaminants in the field drainages were generally below the respective regulatory limits. Health risk assessment studies suggested that users of artificial turf fields, even professional athletes, were not exposed to elevated risks. Preliminary life cycle assessment suggested that the environmental impacts of artificial turf fields were lower than equivalent grass fields. Areas that need further research to better understand and mitigate the potential negative environmental impacts of artificial turf are identified.

“…Note di!erent sampling times. from plants has for example been found for grasses (Kirstine et al, 1998), but a release might also occur by decomposition processes due to the activity of bacteria and fungi equipped with relevant enzymes such as a lignin-decomposing enzyme, the lignostilben-, -dioxygenase (EC 1.13.11.43; Harwood and Parales, 1996;Watillon et al, 1998). Hence, a release of benzaldehyde from wood litter or from other decomposing compounds of the plant shikimate pathway (production of aromatic compounds) is plausible and would explain the increase of benzaldehyde inside the forest canopy.…”

According to recent assessments, tropical woodlands contribute about half of all global natural non-methane volatile organic compound (VOC) emissions. Large uncertainties exist especially about #uxes of compounds other than isoprene and monoterpenes. During the Large-Scale Biosphere/Atmosphere Experiment in Amazonia } Cooperative LBA Airborne Regional Experiment 1998 (LBA-CLAIRE-98) campaign, we measured the atmospheric mixing ratios of di!erent species of VOC at a ground station at Balbina, Amazonia. The station was located 100 km north of Manaus, SE of the Balbina reservoir, with 200}1000 km of pristine forest in the prevailing wind directions. Sampling methods included DNPH-coated cartridges for carbonyls and cartridges "lled with graphitic carbons of di!erent surface characteristics for other VOCs. The most prominent VOC species present in air were formaldehyde and isoprene, each up to several ppb. Concentrations of methylvinyl ketone as well as methacroleine, both oxidation products of isoprene, were relatively low, indicating a very low oxidation capacity in the lower atmospheric boundary layer, which is in agreement with a daily ozone maximum of (20 ppb. Total monoterpene concentration was below 1 ppb. We detected only very low amounts of VOC species, such as benzene, deriving exclusively from anthropogenic sources.
