MODEL RELEASED. Chamber for pollution research. Researcher noting the heights of plants in a simulated haymeadow grassland of conservation value. The plants are kept in a fumigation chamber that produces controlled exposure to the pollutant gas,ozone. The gas is pumped in through the wide polythene tubes running around the outside. The chamber replicates the present and projected ozone climates,and changes in species composition are monitored. Photographed at Close House field station,Newcastle University,UK | |
