Mesothelioma and asbestos exposure has long been linked hubungkankan. Since
the early days of the Holy Roman Empire had noted that slaves who
worked in asbestos mines have lung problems are severe and died at an
early age. However, in recent decades it has become apparent that there are other
potential causes for the development of a rare form of cancer.
A
study conducted by McDonald and McDonald in 1980 showed that About a
25-33 percent of all cases of mesothelioma cancer does not have anything
to do with exposure to asbestos. However, in research prefix found some other specific cause. One of them is the exposure of the zeolite.
Zeolite (wikipedia.org)Is the zeolite?
Known in scientific terms as alkali hydrated aluminum silicate. Zeolite is a mineral group that contains most of hydrated aluminum and silicon compounds. Their common names include clinoptilolite, erionite, Phillipsite, and Mordenite. They are found in volcanic rock and ash and is sometimes used as an additive in animal feed. Because of their porous structure, zeolites can be used as an
absorbent (absorbent materials), textile printing materials, detergents,
and as purifying water and air.
Zeolites
have also been used in several areas of health, among others as a
supplement to a hangover and an adjuvant therapy for various cancers
(FDA did not approve of this treatment). But
there is still a lack of data supporting the efficacy of the
effectiveness of zeolite and no conclusion as to whether zeolite secure.
As a mineral that has a systemic effect on the body, zeolite also remains unclear to this day and requires further research.
Zeolite relationship with mesothelioma
It
has become clear, however, that zeolite dust exposure is associated
with an increased risk of development of malignant mesothelioma
(malignant mesothelioma). Simply to say zeolites are carcinogenic when inhaled. As a matter of International Agency for Research on Cancer placing the
zeolite in the list of groups 1. Categorization inidiberikan
carcinogens when there is sufficient evidence regarding carcinogenicity
in humans causes mesothelioma.Erionite
zeolite is a form of fiber that is clearly associated with mesothelioma
epidemic in villages Anatolian Plateau in Turkey. In the village local volcanic tuff filled with zeolite toxic fibers. A report on the epidemic published in the 2006 edition of March 15 Journal of the National Cancer Institute.
Doctors
in Turkey initiated a study during the 23 years that followed 891 men
and women living in three villages in different Turkish Cappadocia
region. Villagers had been exposed to erionite. The third village used as a village controlled. During the study which started from 1979 to 2003 as many as 372 people have died. Of
the deaths are known to many as 119 people stricken with mesothelioma
cancer and died from the disease or complications of the disease. In
the two villages where the population is exposed to the toxic mineral
known deaths from pleural mesothelioma amounted to 44.5 percent. While in the third village just happened two deaths caused by
mesothelioma, and even then it is known that the two of them when they
are born not from the village controlled.
Data
analysts, including from Harvard professors, namely Philippe Grandjean,
MD, Ph.D., determines the result of mesothelioma in the two events. The village is filled with erionite occurs 200-700 cases per 100,000 people annually. In the village there are only controlled 10 cases per 100,000 people. Therefore, the conclusion is that long-term exposure to erionite is
responsible for a very high incidence of the cancer cases of asbestos in
certain villages of Cappadocia in the Anatolian Plateau.
After the study is completed, the authors suggest that local
authorities were concentrating on ways to prevent exposure to the
environment from harmful zeolite fibers in the hopes of lowering the
risk population for developing the disease mesothelioma.
The
precipitate natural erionite have been found in several western US
states, especially Arizona, Nevada, Utah, Oregon, North Dakota, South
Dakota, and Montana. A
report on ereonite / zeolite in the US (Rom, WN, KR Casey, WT Parry, CH
Mjaatvedt and F. Moatamed. 1983. Health implications of natural fibrous
zeolites for the Intermountain West. Environ Res 30 (1): 1- 8)
noted that residents of the area known as the "Intermountain West" may
be exposed to fibrous zeolite from wind gusts and therefore vulnerable
to the development of mesothelioma. The
state of North Dakota is currently conducting studies related to
erionite exposure areas are known to have this vast mountain.
