This new edition of Occupational and Environmental Medicine concentrates more on the newer kinds of occupational disease including those (like "RSI" and pesticide poisoning) where exposure and effects are difficult to understand. There is specific emphasis on work, health and wellbeing, with links to public health, health promotion, the value of work, disabled people at work, the aging workforce, vocational rehabilitation, evidence based practice, and further chapters on the health effects of climate change and of occupational health and safety in relation to migration and terrorism.
