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.
This can result in shortness of breath, a common symptom exhibited by individuals with asbestosis. [24] Those with asbestosis may be more vulnerable to tumor growth (mesothelioma), because asbestos decreases the cytotoxicity of natural killer cells and impairs the functioning of T helper cells, which detect abnormal cell growth.

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 ...
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.
It can also induce severe side-effects, including fatal pneumonitis. [77] As part of a curative approach to mesothelioma, radiotherapy is commonly applied to the sites of chest drain insertion, in order to prevent growth of the tumor along the track in the chest wall.
The size and development stage of maggots can be used to give a measure of the minimum time since death. [9]: 251–252 Insect activity occurs in a series of waves, and identifying the insects present can give additional information on the postmortem interval. [10] Adipocere, or corpse wax, may be formed, inhibiting further decomposition.
How can I relieve Plan B side effects? Yeah, if you’re feeling even remotely sh*tty, I get that you wanna find a quick fix. The most important thing Dr. Jackson-Bey suggests is to stay hydrated.
Cultural heritage collections contain many materials known to be hazardous to the environment and to human health. Some hazardous substances may be an integral part of the object (such as a toxic paint pigment or a naturally radioactive mineral sample), applied as a treatment after the object was made (such as a pesticide) or the result of material degradation (such as the exudation of ...
