A comparative study using the model developed, showed that product concentration in term of ppm would be an effective measurement of product yields through photocatalytic reduction of carbon dioxide with water vapour.

It was found that the total cost to produce 24,000 m3/d of water from a feed salinity of 15,000 ppm and a water quality of < 400 ppm would be 0.11 £/m3 with a corresponding investment cost of £14.4 million for the drinking water, and for irrigation) obtained product < 1600 ppm) are £0.9/m3 and £11.3 million.

The model was also used to estimate the dose-response of formaldehyde acetal in relation to inhaled formaldehyde accounting for endogenous formaldehyde and showed that exposures in the range of 1-2 ppm would not be sufficient to cause significant increases in tissue formaldehyde compared to background in the normal tissues of the nose.
