Asbestos can be found naturally in the air outdoors and in some drinkable water, including water from natural sources. [20] Even nonoccupationally exposed members of the human population have tens to hundreds of thousands of asbestos fibers per gram of dry lung tissue, equivalent to millions of fibers in each lung. [21]
The signs and symptoms of asbestosis typically manifest after a significant amount of time has passed following asbestos exposure, often several decades under current conditions in the US. [11] The primary symptom of asbestosis is generally the slow onset of shortness of breath , especially with physical activity. [ 12 ]
Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
Asbestos (/ æ s ˈ b ɛ s t ə s, æ z-,-t ɒ s / ass-BES-təs, az-, -toss) [1] is a group of naturally occurring, toxic, carcinogenic and fibrous silicate minerals.There are six types, all of which are composed of long and thin fibrous crystals, each fibre (particulate with length substantially greater than width) [2] being composed of many microscopic "fibrils" that can be released into ...

The symptoms of disease do not usually appear until about 20 to 30 years after the first exposure to asbestos. Although all asbestos is hazardous, products that are friable, e.g. sprayed coatings and insulation, pose a significantly higher hazard as they are more likely to release fibers to the air.
