The Dangers of Exposure to Asbestos
Asbestos was used in a variety of commercial products before it was banned. Research suggests that exposure to asbestos can cause cancer and other health issues.
It is impossible to tell just by looking at something if it's made of asbestos. Neither can you smell or taste it. It is only found when asbestos-containing materials are drilled, chipped or broken.
Chrysotile
At its height, chrysotile provided for 90% of the asbestos produced. It was utilized in a variety of industries which included construction insulation, fireproofing, as well as insulation. Unfortunately, if workers were exposed to this harmful substance, they could develop mesothelioma and other asbestos-related diseases. Since the 1960s, when mesothelioma was first becoming a problem asbestos use has decreased significantly. It is still found in many of the products we use today.
Chrysotile is safe to use provided you have a comprehensive safety and handling plan in place. Personnel handling chrysotile aren't exposed to an unreasonable amount of risk based on the current limit of exposure. Lung fibrosis, lung cancer and mesothelioma are all associated with breathing in airborne respirable fibres. This has been confirmed both for intensity (dose) as and the duration of exposure.
One study that examined an industrial facility that used almost exclusively chrysotile to manufacture friction materials compared mortality rates in this facility with national mortality rates. It was concluded that for 40 years of preparing asbestos chrysotile in low levels of exposure, there was no significant additional mortality in this factory.
Chrysotile fibers are generally shorter than other types of asbestos. They can pass through the lungs, and enter the bloodstream. This makes them much more prone to causing health effects than fibrils with a longer length.
When chrysotile is mixed into cement, it's very difficult for the fibres to air-borne and cause health hazards. The fibre cement products are extensively used throughout the world particularly in buildings such as schools and hospitals.
Research has proven that amphibole asbestos such as amosite or crocidolite is less likely than chrysotile in causing disease. These amphibole types are the main cause of mesothelioma, and other asbestos legal-related diseases. When cement and chrysotile are mixed, a durable, flexible product is created that is able to stand up to extreme environmental hazards and weather conditions. It is also easy to clean up after use. Asbestos fibres can be easily removed by a professional and safely eliminated.
Amosite
Asbestos refers to a group of silicate mineral fibrous that naturally occur in certain types of rock formations. It is divided into six groups which include amphibole (serpentine), Tremolite (tremolite), anthophyllite (crocidolite) and anthophyllite.
Asbestos minerals consist of long, thin fibres that vary in length from extremely thin to broad and straight to curled. They are present in nature as individual fibrils, or as bundles that have splaying ends, referred to as fibril matrix. Asbestos can also be found in powder form (talc) or mixed with other minerals to form talcum powder or vermiculite. These are widely used in consumer products like baby powder, cosmetics and face powder.
The largest use of asbestos was in the first two-thirds period of the twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing and other construction materials. Most occupational exposures were to asbestos fibres in the air, however certain workers were exposed to toxic talc or vermiculite and also to fragments of asbestos-bearing rock (ATSDR, 2001). Exposures varied according to the industry, time frame and geographical location.
Most of the occupational exposures to asbestos were because of inhalation, but certain workers were exposed via skin contact or through eating contaminated food. Asbestos is found in the environment due to natural weathering and degrading of contaminated materials, such as ceiling and floor tiles, car brakes and clutches as well as insulation.
There is evidence to suggest that non-commercial amphibole fibers could also be carcinogenic. These fibres are not tightly woven like the fibrils found in amphibole and serpentine but are instead loose and flexible, and needle-like. These fibers are found in mountains, sandstones and cliffs of many countries.
Asbestos can be found in the environment as airborne particles, but it can also leach into soil and water. This can be due to both natural (weathering of asbestos-bearing rocks) and anthropogenic causes (disintegration of asbestos-containing wastes and disposal in landfill sites). Asbestos contamination of surface and ground water is mostly a result of natural weathering, but has also been caused by human activities like mining and milling demolition and dispersal asbestos-containing materials, and the removal of contaminated soils for disposal in landfills (ATSDR 2001). Airborne asbestos fibres are the main cause of illness among people exposed to asbestos in their occupation.
Crocidolite
Inhalation exposure to asbestos is the most frequent way people are exposed to the dangerous fibres, which can be absorbed into the lungs and cause serious health problems. This includes asbestosis and mesothelioma. Exposure to the fibres can occur in different ways, including contact with contaminated clothes or building materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is a smaller, more fragile fibers that are easier to breathe in and may lodge deeper in lung tissue. It has been linked to a greater number of mesothelioma-related cancers than any other form of asbestos.
The six major types of asbestos are chrysotile, amosite, epoxiemite, tremolite, anthophyllite, and actinolite. Chrysotile and amosite are the most commonly used forms of asbestos and account for 95% of the commercial asbestos that is used. The other four asbestos types are not as prevalent, but could still be found in older structures. They are not as dangerous as amosite or chrysotile however they could still be a risk when mixed with other minerals or when mined near other mineral deposits like talc and vermiculite.
Numerous studies have demonstrated that there is a link between stomach cancer and asbestos exposure. However the evidence isn't conclusive. Some researchers have cited an SMR (standardized mortality ratio) of 1.5 (95% CI: 0.7-3.6) for all workers exposed to asbestos, while others have reported an SMR of 1.24 (95% C.I. 0.76-2.5) for those working in chrysotile mines and mills.
The International Agency for Research on Cancer (IARC) has classed all forms of asbestos as carcinogenic. All asbestos types can cause mesothelioma, but the risk is different based on how much exposure, what type of asbestos is involved and the length of time that exposure lasts. The IARC has recommended that the prevention of all asbestos types should be the highest priority since this is the best option for people. However, if a person has been exposed to asbestos in the past and suffer from an illness such as mesothelioma, or other respiratory ailments They should seek advice from their GP or NHS 111.
Amphibole
Amphibole is a class of minerals that form long prisms or needlelike crystals. They are a kind of inosilicate mineral made up of double chains of SiO4 molecules. They usually have a monoclinic crystal structure however some may have an orthorhombic structure. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains comprise (Si, Al)O4 tetrahedrons linked together in rings of six tetrahedrons. The tetrahedrons are separated by octahedral strips.
Amphiboles are present in metamorphic and igneous rock. They are usually dark and hard. Due to their similarity in hardness and color, they can be difficult for some to differentiate from the pyroxenes. They also share a similar pattern of cleavage. Their chemistry allows a wide variety of compositions. The different minerals within amphibole can be identified by their chemical compositions and crystal structures.
Amphibole asbestos includes chrysotile and asbestos the five asbestos types: amosite, anthophyllite (crocidolite), amosite (actinolite) and amosite. Each variety of asbestos has its own distinct properties. Crocidolite is considered to be the most hazardous asbestos type. It is made up of sharp fibers that are easily inhaled into the lung. Anthophyllite comes in a brownish-to yellowish hue and is made primarily of magnesium and iron. This variety was once used in products like cement and insulation materials.
Amphiboles are difficult to analyse due to their complicated chemical structure and the numerous substitutions. Therefore, a detailed analysis of their composition requires special methods. The most widely used methods of identifying amphiboles include EDS, WDS, and XRD. However, these methods only give approximate identifications. For instance, these techniques can't distinguish between magnesio hastingsite and magnesio-hornblende. Furthermore, these techniques do not distinguish between ferro-hornblende and pargasite.
