  • Population health

    22 August 2000

    A measure of health status of populations, proposed in recent years to selectively replace use of the terms human health, which is more restrictive, and public health, which also encompasses preventive and curative measures and infrastructures.

  • WHO (World Health Organisation)

    22 August 2000

    A UN agency created in 1948 to deal with global health issues and to achieve as high a level of physical, mental and social well-being as possible for peoples of the world. It is involved in a variety of environemental studies, including the impact of climate change and ozone depletion on health, in conjunction with other agencies such as the World Meteorological Organisation (WMO) and the United Nations Environment Program(UNEP).

  • CFC's (Chlorofluorocarbons)

    21 August 2000

    A group of chemicals containing chlorine (Cl), fluorine (F) and carbon (C), sometimes referred to by their trade name Freon. These synthetic compounds were used extensively for refrigeration and aerosol sprays until it was realized that they destroy ozone (they are also very powerful greenhouse gases) and have a very long lifetime once in the atmosphere (more than 100 years). The Montreal Protocol agreement of 1987 has resulted in the scaling down of CFC production and use in industrialised countries.

  • Cholera

    21 August 2000

    A bacterial disease caused by drinking water contaminated by sewage or eating food that has not been washed or is inadequately cooked. It is common in areas where the growth in population has outstripped the development of facilities for providing clean water or disposing of sewage. The problem is most severe in warm climates where high temperatures encourage the growth of the cholera bacteria.
