This Monograph provides the general respiratory physician with a working reference based on the latest literature and expert opinion. The initial chapter provides a contemporaneous global perspective of the epidemiology of occupational and environmental lung diseases in an ever-evolving landscape. The book then goes on to consider specific occupational lung diseases. Each chapter has a clear clinical focus and considers: key questions to ask in the history; appropriate investigations to undertake; differential diagnoses; and management. Controversies or diagnostic conundrums encountered in the clinic are also considered, and further chapters are more broadly centred on the non-workplace environment; specifically, the respiratory symptoms and diseases associated with both the outdoor and indoor environments.
