Environmental health. Catching up with the developed world.

Environmental health is the ecological balance that must exist between man and his environment in order to ensure his well-being. This paper describes the range of environmental hazards (physical, biological, chemical and social) and discusses the differences in level and quality of environmental health programmes between developed and developing countries. The hazards are the same in both realms; the difference is in the level of advocacy and, thus, the demand for implementation of sound environmental health policies and practices. Issues which developing countries need to address to improve environmental health management are outlined.
