Shipyards and factory workers exposed to dangerous asbestos

Every day many of us have to live with the fact that some companies deliberately expose their workers to dangerous asbestos, knowing the consequences. It is hard for many to believe the insensitive attitudes behind such decisions. Fortunately, there are people committed to try to right the wrongs. Many people have dedicated their lives to the study of asbestos and links to mesothelioma and lung cancer. It is this dedication that will be the impetus for ever finding a study that examined cure.One asbestos exposure and shipyard workers called "the asbestos content in lung tissue, lymph nodes, and pleural plaques from former employees shipyard "Dodson RF, Williams MG Jr, Corn CJ, Brollo A and C. Bianchi - Am Rev Respir Dis.1990 Oct; 142 (4) :843-7. Department of Cell Biology and Environmental Sciences, University of Texas Health Center, Tyler 75710. Here's an excerpt:. "Samples autopsy eight former shipyard workers were obtained from lung parenchyma, tracheal lymph nodes, and pleural plaques Tissue from each respective area was prepared using a technique modified bleach digestion, and the residue collected on a 0.2 micron pore polycarbonate filter or cellulose mixed ester 0.22 micron. Quantification of ferruginous bodies and uncoated fibers made with optical and electronic transmission microscopy, respectively. Differences asbestos load were observed for each site. ferruginous bodies were observed in both the parenchyma and nodes but not on plates. three subjects were found to have more ferruginous bodies per gram dry weight of the lymph nodes in the lung parenchyma. Additional found that subjects who are more coated fibers per gram in the nodes in the parenchyma. amphibole and chrysotile fibers were observed in the lung and extrapulmonary sites, chrysotile is the predominant asbestiform plates. Most fibers without coating both the nodes and the plates were less than or equal to 5 microns in length. However, some fibers with dimensions in accordance to the "hypothesis Stanton" came to both areas. These residual patterns most likely reflect the effect on the burden of lung clearance compared to the eventual accumulation and stasis in extrapulmonary areas.

Dose-response of 5 to 40 years after the onset of exposure at work Short "by Seidman H, Selikoff IJ Gelb and SK.Am J Ind Med 1986, 10 (5-6): 479-514. Here's an excerpt:. "Cohort of 820 men in an asbestos factory amosite Paterson, New Jersey, which began work in 1941/45 between 5 and 40 years after starting work He noted Most of the cohort had a limited duration of work experience (days, weeks, months), although some men worked for several years until the factory closed in 1954. With white men in New Jersey as the control population, standardized mortality ratios ( RME) 500 are evident for the cohort of lung cancer and non-infectious lung diseases (including asbestosis), being almost 300 for the total and about 170 for all causes of death cancer. A statistically significant SMR of nearly 200 cancer is colon-rectum. Incidence of mesothelioma initially shows a strong relationship with the advance of time from the start of exposure, and then tails off.'s main concern is to study the dose-response patterns. response measured by mortality relevant causes of death, while the dose of direct asbestos was measured in two ways. One way is the amount of time worked in the factory and the other was cumulative fiber exposure of the individual, which calculated by multiplying the stated length of time worked by the fiber estimated exposures associated with the particular job that the worker was in the factory. Whatever the measurement of the dose used, it was found that in general, the lower the dose, the longer it took for adverse mortality becomes apparent, and also the smaller the magnitude of that adverse mortality.
