The possibility of long-term depletion of the ozone layer is of serious concern and Government policy remains the earliest possible phasing out of the production of ozone-depleting chemicals. The achievement of this will mean that depletion does not continue at present rates for 20 years.

Exposure to ultraviolet radiation—UV—is an important factor in the number of cases of skin cancer which develop and levels of UV at ground level are influenced by changes of levels of ozone in the stratosphere. However, these are only one factor influencing the numbers of skin cancers. Seasonal variations in solar UV levels and short term variations due to cloud cover and local weather conditions are far in excess of any variations anticipated as a result of ozone depletion. The main risk factor which is believed to account for the increase seen in the incidence of skin cancer is the increased extent to which people expose themselves to the sun. The programme of work following the publication of "Health of the Nation" in July includes work to halt the increase in skin cancers.
