Hawai‘i’s Asbestos Legacy: A Growing Mesothelioma Threat

​​Mesothelioma deaths in the U.S. surged by 20% between 1990 and 2019, according to BMC Public Health. This increase is tied directly to decades of asbestos exposure, especially among workers in construction, shipbuilding, military service, and manufacturing.

The rise in cases is particularly alarming in Hawai‘i, where thousands of veterans have been exposed to asbestos while working on Navy ships, submarines and maintenance facilities at the Pearl Harbor Naval Shipyard since World War II. The state health department reported over 700 asbestos-related deaths between 1999 and 2017, including 139 from mesothelioma.

Cancer-Causing Asbestos Found Near Honolulu Vermiculite Plant

More than 40 years since a vermiculite-processing facility near the Honolulu airport was shuttered over concerns about asbestos contamination, harmful vermiculite and asbestiform tremolite residue remains in the soil placing nearby Honolulu residents at risk.

Hawai’i factory’s troubled history

For decades, the facility known as the Vermiculite of Hawai’i Plant operated near the Daniel K. Inouye International Airport processing vermiculite shipped from a Libby, Montana, mine operated by W.R. Grace & Co. The plant used an exfoliation process that released asbestos particles into the air.

Although the Hawai’i facility closed in 1983 and remediation was performed in 2001, a new study confirms that dangerous levels of vermiculite and asbestiform tremolite remain. As asbestos and fibrous particles can persist in soil and air for years, the risk to nearby residents remains.

 

Navy Veterans Face Higher Risk of Mesothelioma

Navy veterans have been exposed to cancer-causing asbestos fibers at levels higher than other branches of the military, according to new research.

According to a study of British and Australian veterans published in Scientific Reports, naval personnel have been exposed to higher levels of asbestos because of the time they spent on ships and submarines, particularly for service members who worked in engine rooms, where maintenance procedures involved disturbance of asbestos on pipework, turbines, boilers and other machinery. As a result, sailors suffer high rates of asbestosis, mesothelioma, and lung cancer, even when other lifestyle factors are controlled.

 

How to Ensure Your Home Is Safe from Asbestos Dangers

While Hawaiʻi residents are increasingly aware of the serious health risks associated with occupational exposure to asbestos in the workplace and from military service, many don’t realize how frequently they may come in contact with the material.

Used for insulation, as a fire retardant and many other applications, asbestos can be found in homes and in military housing throughout Hawaiʻi. In addition, generations have been exposed to asbestos in the workplace and in military service.

Hidden Asbestos Danger Lurks in Aging Homes, Buildings

Asbestos has been widely used in the construction of buildings in Hawai‘i for generations. According to the Hawai‘i State Department of Health, most residential buildings in Hawaii contain some asbestos, which can be found in ceilings, walls, insulation and flooring.

While these materials pose little risk when a building is kept in good condition, they become hazardous when asbestos is disturbed. Storms, high winds and natural disasters can cause minute fibers to break away and create a risk to human health.

Despite restrictions on asbestos, Hawai‘i residents continue to succumb to mesothelioma cancer

While it’s well-established that the deadly form of cancer known as mesothelioma is caused solely by exposure to asbestos, thousands of people throughout the U.S. mainland and Hawaii continue to die from the disease every year.

About 3,000 cases of mesothelioma are registered each year in the United States. In Hawaii, there are approximately 38 asbestos-related deaths a year, according to the U.S. Centers for Disease Control.

Mesothelioma was discovered in the late nineteenth century and gradually came to be associated with exposure to asbestos. The mineral has been used throughout history, but as the Industrial Revolution took hold, more and more uses were found.

Asbestos and Mesothelioma Aren’t Going Away

The serious health risks associated with asbestos exposure have been known for generations. The naturally occurring fiber is the only known cause of mesothelioma, an incurable and deadly form of cancer of the lining of the lungs and internal organs. Legal and regulatory scrutiny of asbestos use has ramped up over the years — including a 2024 ban on chrysotile asbestos — but an alarming number of Americans continue to die from mesothelioma every year. While mesothelioma diagnosis rates have fallen among men, they have remained steady among women.

Global Mesothelioma Cases Surge as Asbestos Use Continues

Cases of mesothelioma around the world have been increasing along with a rise in the global use of asbestos, despite an acknowledgment more than 40 years ago by the World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) that all forms of asbestos are carcinogenic.

Asbestos exposure causes mesothelioma, a cancer of the tissue that lines the lungs, chest wall, and abdomen. Given that asbestos continues to be used globally in a variety of commercial products, it’s not surprising that mesothelioma cases and deaths associated with the disease have been rising too.

EPA Ban on Chrysotile Asbestos Will Save Lives, Hold Corporations Accountable

After years of tireless work by advocacy groups on behalf of cancer victims, the Environmental Protection Agency (EPA) is finally taking action against asbestos, a dangerous substance known to cause cancer, severe illness and countless fatalities each year.

In March 2024, the EPA took a major step toward protecting Americans from asbestos exposure with a historic ban on a common type of asbestos known as chrysotile. It was the first substantive move to protect Americans from asbestos exposure in decades.

5 Most Common Ways People Are Exposed to Asbestos

Until about four decades ago, most structures in Hawaii were built with material containing asbestos, including the state’s military bases, state buildings, homes and even schools.

While the health risks from these materials are well-known today, the use of asbestos – while highly regulated in Hawaii – is still allowed in certain products, creating serious risk for anyone who comes in contact with them.

Asbestos is composed of six minerals that occur naturally in the environment as bundles of fibers that can be separated into extremely fine threads for commercial and industrial uses. The fibers are resistant to heat, fire and chemicals and do not conduct electricity.
