The Dangers of Exposure to Asbestos Before it was banned, asbestos was widely used in commercial products. According to research, exposure to asbestos can cause cancer as well as other health issues. You cannot tell by just looking at something if it's made of asbestos. Also, you cannot smell or taste it. It is only found in the event that asbestos-containing products are chipped, drilled or broken. Chrysotile At the height of its use, chrysotile made the majority of asbestos production. It was utilized in a variety of industries, including construction, insulation, and fireproofing. Unfortunately, if workers were exposed to this harmful substance, they could develop mesothelioma as well as other asbestos related diseases. Thankfully, the use of this harmful mineral has diminished significantly since awareness of mesothelioma began to grow in the 1960's. However, it is still present in trace amounts. are still present in many of the products we use today. Chrysotile is safe to use in the event that you have a complete safety and handling plan in place. It has been determined that, at today's controlled exposure levels, there is no danger to the people working with the substance. Lung cancer, lung fibrosis and mesothelioma were all connected to breathing in airborne respirable fibres. This has been confirmed for both intensity (dose) and time of exposure. In one study mortality rates were compared among a factory which used almost exclusively Chrysotile for the production of friction materials and national death rates. The study revealed that after 40 years of processing low levels of chrysotile, there was no significant rise in mortality in this factory. In contrast to other forms of asbestos, chrysotile fibres tend to be smaller. They can enter the lungs, and even enter the bloodstream. They are more likely to cause health problems than fibres with longer lengths. When hayward asbestos law firm is mixed into cement, it's extremely difficult for the fibres to air-borne and pose any health risks. Fibre cement products are extensively used throughout the world particularly in structures like hospitals and schools. Research has shown that amphibole asbestos, such as amosite or crocidolite is less likely than chrysotile in causing disease. These amphibole varieties are the primary cause of mesothelioma, and other asbestos-related diseases. When chrysotile mixes with cement, it forms a strong, flexible construction product that can withstand extreme conditions in the weather and other environmental dangers. It is also simple to clean after use. Professionals can safely get rid of asbestos fibres after they have been removed. Amosite Asbestos is a category of silicate mineral fibrous that are found naturally in specific kinds of rock formations. It is composed of six general groups: amphibole, serpentine anthophyllite, tremolite, anthophyllite, crocidolite (IARC 1973). Asbestos minerals are composed of thin, long fibers that vary in length from fine to broad. They can also be curled or straight. They are present in nature in the form of individual fibrils or bundles with splaying ends referred to as fibril matrix. Asbestos minerals can also be found in the form of a powder (talc) or mixed with other minerals and sold as talcum powder and vermiculite and are used in consumer products such as baby powder cosmetics, face powder and baby powder. The heaviest asbestos use was during the first two-thirds of the twentieth century in the period when it was employed in insulation, shipbuilding, fireproofing, and other construction materials. The majority of occupational exposures involved asbestos fibres borne by air, but some workers were exposed vermiculite and talc that had been contaminated as well as to fragments of asbestos-bearing rocks (ATSDR, 2001). Exposures varied according to industry, time, and geographic location. The exposure to asbestos in the workplace is mostly caused by inhalation. However there have been instances of workers being exposed through skin contact or by eating food items contaminated with asbestos. Asbestos is now only found in the environment from the natural weathering of mined minerals and the deterioration of products contaminated with asbestos like insulation, car brakes, clutches and ceiling and floor tiles. It is becoming evident that non-commercial amphibole fibres may also be carcinogenic. These fibers aren't knit like the fibrils found in amphibole and serpentine but are instead loose as well as flexible and needle-like. These fibers are found in the cliffs and mountains in a variety of countries. Asbestos can be found in the environment as airborne particles, but it also leaches into water and soil. This can be caused by natural (weathering and erosion of asbestos-bearing rocks) and human-caused (disintegration and removal of asbestos-containing wastes from landfill sites) sources. Asbestos contamination in ground and surface water is mostly caused by natural weathering. However it is also caused by anthropogeny, such as by the milling and mining of asbestos-containing materials, demolition and dispersal, and the removal of contaminated dumping material in landfills (ATSDR 2001). Asbestos fibres that are emitted from the air are the most significant cause of disease among those exposed to asbestos in their work. Crocidolite Inhalation exposure is the most popular method of exposure to asbestos fibres. These fibres can infiltrate the lung and cause serious health issues. This includes asbestosis and mesothelioma. Exposure to fibers can occur in different ways too including contact with contaminated clothing or building materials. This type of exposure is especially dangerous when crocidolite (the blue asbestos form) is involved. Crocidolite is smaller and more fragile fibers, which are easier to breathe and can be lodged deeper into lung tissue. It has been linked to a larger number of mesothelioma-related cancers than any other form of asbestos. The main types are chrysotile and amosite. The most common asbestos types are chrysotile and epoxiemite, which together comprise the majority of commercial asbestos employed. The other four asbestos types are not as well-known, but can still be found in older structures. They are less hazardous than amosite or chrysotile, but they can still be a danger when mixed with other minerals, or when mined near other mineral deposits like vermiculite and talc. Many studies have discovered an association between asbestos exposure and stomach cancer. The evidence isn't unanimous. Some researchers have cited an SMR (standardized death ratio) of 1.5 (95 percent confidence interval: 0.7-3.6), for all asbestos workers. However, others have reported an SMR of 1,24 (95% confidence interval: 0.76-2.5), for workers 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, however, the risk is dependent on the amount of exposure, what kind of asbestos is involved and how long the exposure lasts. The IARC has recommended that abstaining from all asbestos forms should be the highest priority because this is the best option for individuals. However, if someone has been exposed to asbestos in the past and suffer from a disease such as mesothelioma or other respiratory conditions, they should seek guidance from their GP or NHS 111. Amphibole Amphiboles are a collection of minerals that may form prism-like or needle-like crystals. They are an inosilicate mineral composed of double chains of SiO4 molecules. They are a monoclinic system of crystals, however certain crystals have an orthorhombic form. The general formula of an amphibole is A0-1B2C5T8O22(OH,F)2. The double chains contain (Si, Al)O4 tetrahedrons linked together in a ring of six tetrahedrons. The tetrahedrons are separated from one another by octahedral sites in strips. Amphibole minerals are found in metamorphic and igneous rocks. They are usually dark-colored and hard. They can be difficult to differentiate from pyroxenes due to their similar hardness and colors. They also share a corresponding design of cleavage. Their chemistry can allow for a variety of compositions. The different amphibole mineral groups are identified by their chemical compositions and crystal structures. The five asbestos types in the amphibole family include amosite, anthophyllite and crocidolite. They also include actinolite. Each type of asbestos comes with its own distinctive properties. Crocidolite is the most dangerous asbestos type. It contains sharp fibers which are easily breathed into the lungs. Anthophyllite is brown to yellowish in color and is made up of iron and magnesium. This type was used to make cement and insulation materials. Amphibole minerals are hard to analyze due to their a complicated chemical structure and many substitutions. Therefore, a thorough analysis of their composition requires specialized techniques. EDS, WDS and XRD are the most widely used methods for identifying amphiboles. These methods can only provide approximate identifications. These techniques, for example can't distinguish between magnesio hornblende and magnesio hastingsite. In addition, these techniques can not distinguish between ferro hornblende and pargasite.
