The exposure is never only the exposure.
Sixty questions in environmental health, each with the working shown. Not to be memorised — to be argued with until the reasoning is yours.
Written for students of public health and epidemiology by Yahya M. Al-Farsi, Professor of Public Health and Epidemiology, Sultan Qaboos University. The cases are Omani and Gulf: a dust storm over Muscat, a desalination plant, a midday ban on outdoor work, a well that should not have been drunk from.
