Laryngeal Cancer and the Railroad

About one-third of all head and neck cancers are laryngeal. They are associated with high mortality and morbidity rates. They are more prevalent in males than women.

Bnsf railway interstitial lung disease is contesting Valdez's Medical Causation Expert, and seeks a court order to limit or preventing his testimony during the trial.

Perchloroethylene

Tetrachloroethylene can also be referred to as Perchloroethylene and is a manufactured chemical used to dry clean fabrics, degrease metal, and to make other chemicals. It is also found in a range of consumer products, such as paint and spot removers.

In short-term exposure, PERC can cause irritation to the skin, eyes and the nose. It's also a possible carcinogen, which can cause irritation to the larynx. Long-term exposure to high levels of PERC can cause respiratory issues such as pneumonia and liver cancer.

Exposure to PERC can occur when it's released into the air through dry cleaning processes and when contaminated clothing is thrown out after being cleaned. People may also be exposed by inhaling it from liquid spills or vapors. It can also infiltrate homes and workplaces through the groundwater, Bnsf railway interstitial lung disease soil, or through an intrusion process known as vapor.

ATSDR and EPA both contain information on the health effects associated with PERC exposure. The toxicity of PERC is dependent on the amount as well as the frequency and duration of exposure. Inhalation or oral exposures to PERC in humans and animals rapidly enters bloodstreams. The most commonly targeted tissues for PERC are the central nervous system, kidneys and liver. It can also impair color vision.

ATSDR does not consider the risk to PERC of the general population from streams, rivers and drinking water. Biosolids, disposal routes and other environmental laws are expected to address these channels.

Diesel Exhaust

Railroad workers who are exposed to exhaust fumes from diesel engines have a higher risk of lung cancer. The International Agency for Research on Cancer (IARC) has classified diesel engine emissions as a class 1 carcinogen. This puts it in the same class as arsenic, asbestos, formaldehyde and benzene as well as fine silica.

Diesel fuel fumes may contain the metals that cause laryngeal carcinoma as well as PAHs (polycyclic aromatic hydrocarbons). These chemicals are produced when coal, oil, or gasoline is burnt. They are found in diesel fumes and cigarettes smoke. There is no safe exposure limit for PAHs, therefore any exposure to them should be avoided.

In animal studies, mice which were exposed to filter or unfiltered diesel exhaust had higher tumor rates than those who were not exposed it. They also showed histopathological modifications in the nasal cavity and other organs like the pharynx and trachea, esophagus, forestomach, glandular stomach, kidneys, liver, adrenals, spleen, and the lungs.

Diesel engines are used to power trains, trucks buses, farming and construction equipment. Exposure to exhaust fumes from diesel engines is a problem for many kinds of railroad workers, especially those that operate locomotives. Exposure to these exhaust fumes could cause lung problems such as COPD. This can be exacerbated by smoking, which can increase the risk of respiratory issues and other health problems caused by exhaust fumes from diesel vehicles.

Asbestos

Asbestos, a carcinogen, can cause bnsf railway scleroderma workers to develop laryngeal cancer. This harmful substance has been largely removed from being used by the bnsf railway interstitial lung disease industry but is still present on the electrical panels and pipe insulation and pipe insulation, is still present. It is also found in the brake shoes of trains.

A number of large cohort studies have revealed that exposure to asbestos can increase the risk of laryngeal cancer. These studies have shown some evidence of a relationship between dose and response, but results vary. The International Agency for Research on Cancer recently published a report that confirmed the link between asbestos and laryngeal cancer.

The Institute of Medicine (an independent health arm of the National Academy of Sciences) has also affirmed that asbestos is a significant cause of laryngeal cancer. These findings have bolstered the evidence that asbestos is a carcinogen.

Asbestos exposure could cause many serious health issues, including cancer. These include pleural effusions which are fluid accumulations in the pleura, also known as the lining of the lungs. These conditions can restrict airflow and make it difficult to breathe. Inhaling diesel engine smoke and fumes can exacerbate these conditions.

Asbestos and bnsf railway interstitial lung disease diesel exhaust are only some of the dangerous substances that expose bnsf railway black lung disease workers for respiratory illnesses of various kinds. These conditions can significantly reduce the quality of life. An experienced asbestos lawyer can assist injured railroad workers to seek compensation for the damage they've suffered.

Beryllium

Beryllium is found in nature in minerals such as beryl and bertrandite. It is one the lightest metals, and it has many useful characteristics, including strong thermal and electrical conduction as well as resistance to wear and corrosion. Due to these properties beryllium can be found in a range of manufacturing products. These include transistors, aerospace components and nuclear reactors, as well as golf clubs. The majority of exposures to beryllium that cause health concerns occur during beryllium production.

Like asbestos beryllium, it is carcinogen that could cause lung cancer. It also can cause other serious illnesses, including chronic berylliosis. Chronic berylliosis, also known as a systemic disease that causes inflammation in the lungs and other organs of the body. It is similar to sarcoidosis and often difficult to identify. It is difficult to treat and may cause death.

Beryllium exposure can cause sensitization. This is an allergic response. People who are sensitive to beryllium can experience symptoms like sneezing, coughing, or wheezing. Not all people exposed beryllium will develop sensitivities.

Workers who are exposed to beryllium within the workplace must adhere to hazard-control measures. If this is not possible then steps should be taken to reduce exposure by using the hierarchy. This may include isolating and enclosing processes which may expose workers to beryllium.
