W85-W99: Exposure to electric current, radiation and extreme ambient air temperature and pressure

W99: Exposure to other and unspecified man-made environmental factors

The group of conditions classified under "Exposure to other and unspecified man-made environmental factors" pertains to various health problems arising from human-induced environmental components. These elements could be physical, chemical, or biological hazards introduced into the environment by humans. Physical hazards may involve radiation, noise or thermal pollution, while chemical hazards may include exposure to harmful substances like industrial pollutants, pesticides, and heavy metals. Biological hazards, on the other hand, refer to exposure to infectious agents. The symptoms and progression of these conditions often vary, with many individuals experiencing respiratory issues, skin problems, or gastrointestinal disorders. The transmission largely depends on the nature of the man-made environmental factor and the extent and duration of exposure. These conditions impact various body systems and could potentially lead to chronic diseases, depending on the severity and frequency of exposure.
