Atmospheric ozone and plant damage in the United Kingdom
Environmental Pollution (1970), 1975Abstract Three tobacco varieties, differentially susceptible to ozone, were exposed outdoors 32 km west of central London, during the summer of 1972. At the same time the atmosphere was continuously monitored for ozone. Extensive damage appeared on the leaves of the sensitive variety (Bel-W3), but little or no damage was observed on the two more ...

Gas-phase mercury in the atmosphere of the United Kingdom
Atmospheric Environment, 1998Abstract Measurements of total gaseous mercury have been made over a period of 1 yr using a cold vapour atomic fluorescence absorption technique at Harwell, a rural site in central southern England. The mean concentration was 1.68 ng m−3, with a maximum hourly mean concentration of 20.5 ng m−3 and a minimum hourly mean concentration of 0.26 ng m−3 ...

The δ18O signature of atmospheric CO2 can be used as a tracer for estimating gross primary production (GPP), however, this method requires having detailed knowledge of δ18O signatures of numerous water reservoirs and isotopic fractionation associated with transfer processes, which are highly variable due to the complexity of the ...

ON THE DESIGN FLEXIBILITY OF ATMOSPHERIC CRUDE FRACTIONATION UNITS
Chemical Engineering Communications, 1998Abstract This paper is devoted to study the effect of the design parameters on atmospheric crude distillation units. The following conclusions are obtained: Pump-around circuits play only a role in energy integration, but they have imperceptible effects on the separation goals.
