EPA Removes Part of Libby Asbestos Cleanup from Superfund List

The U.S. Environmental Protection Agency has deleted a 45-acre portion of the Libby Asbestos Superfund site from the National Priorities List. The EPA and the Montana Department of Environmental Quality have agreed that institutional controls to prevent any future exposure to asbestos in the area were satisfied. It’s a step closer to finishing the decontamination of the longest-running, man-made environmental disaster in American history. The sprawling Superfund site, which was placed on the National Priorities List in 2002, was originally divided into eight operable units. The units were based upon the extent of contamination and complexity of cleanup needed. Operable Unit 2 last week was the first of the eight removed. All but one other operable unit — the actual mine site — are expected to follow soon. “This is a huge step,” Mike Cirian, EPA remedial project manager, told The Mesothelioma Center at Asbestos.com. “To see this now, to know we’ve made this a safer place to live, a place I’m happy to have my grandkids come, is big.” Vermiculite Mining for 70 Years The Superfund site was created because of high levels of amphibole asbestos throughout the communities of Libby and nearby Troy, in northwest Montana. The contamination stemmed from the massive W.R. Grace &Company vermiculite mine operation that once spread asbestos dust throughout the region, sickening miners and nearby residents who never worked there. The ...

In conclusion, the additional analyses we performed according to Mezei et al’s suggestions confirm the association between asbestos exposure and pericardial and TVT mesothelioma, supporting the c ausal role of asbestos for all mesotheliomas. ReNaM`s continuing surveillance system with national coverage is a precious platform for launching analytical studies on pleural and extra pleural mesothelioma. References 1.

A recent rise in litigation linking cosmetic talc with mesothelioma and lung cancer will continue throughout 2020, despite companies abandoning the product in the hope of avoiding costly verdicts. The number of legal cases is expected to increase by 10% this year, building on an 11% rise in 2019, according to KCIC, a well-regarded consulting firm based in Washington, D.C., that manages asbestos product liabilities. “A new trend we have started to see is talc allegations showing up in traditional asbestos complaints,” said KCIC Vice President Michelle Potter during a recent webinar that looked at past litigation...

Rare thoracic malignancies, those with an incidence lower than 6 per 100,000 as a threshold of rarity, include epithelial tumors of the trachea, thymus and malignant pleural mesothelioma (MPM). Foremost among these rare tumors is mesothelioma, accounting for 2.1 cases per 100,000 people per year [1]. While we are witnessing years of exciting progress for lung cancer patients, very few advances have been made in MPM since the approval of pemetrexed in 2004 [2]. Not surprisingly, life expectancy of MPM remains suboptimal with a median overall survival (OS) of less than 1  year and 5-year OS of approximately 5% [1].

Malignant pleural mesothelioma (MPM) is a rare but aggressive cancer. The long latency from asbestos exposure to MPM development, as well as the absence of early symptoms, lead to late diagnosis and very poor prognosis, with a life expectancy of 9-18 months from diagnosis [1]. Only a small number of patients is suitable for multimodal therapy, including surgery, and the majority of patients receive palliative chemotherapy.

Patients with pleural mesothelioma cancer may have another treatment option after the U.S. Food and Drug Administration approved the use of pembrolizumab for certain metastatic tumors this week. Pembrolizumab, often known by the brand name Keytruda, is a well-known immunotherapy drug already being used with mixed success for several cancers. This latest FDA approval is for the treatment of adult and pediatric cancers with unresectable disease and high mutational burden that have progressed following prior treatment and have no alternative treatment options. A number of mesothelioma patients already are being treated with p...

A multicenter research team of specialists has uncovered a surprising underutilization of treatments for pleural mesothelioma cancer in women. Clinical Lung Cancer recently published the findings, which showed a significant sex-based disparity in the receipt of care for women when compared with that of men. Women were 15% less likely to receive aggressive mesothelioma surgery that has proven its worth in extending lives for this cancer, which has no definitive cure. They also were 20% less likely to receive chemotherapy than were men. “This is concerning, absolutely,” Dr. Charles Simone, chief medical officer a...

Exposure to asbestos causes non-malignant and malignant diseases including asbestosis, lung cancer, and mesothelioma. The modern history of such diseases goes back more than a century.

Consumer concerns and the threat of potentially costly lawsuits are driving cosmetic companies away from the long-standing manufacture of talc-based products. Reuters News Service is reporting that Revlon, Chanel and L’Oreal — three of the biggest names in U.S. cosmetics — have been turning quietly to talc alternatives in the last few years. Talc is the softest mineral on Earth and is used ubiquitously in thousands of personal care and cosmetic products to absorb moisture, provide lubrication and improve feel. Unfortunately, talc also is mined near the Earth’s surface in proximity to asbestos, which...

The COVID-19 pandemic closed educational institutions everywhere, but it also opened a door to the acceleration of vitally important asbestos abatement in schools where children would have been in attendance. Business has been booming. “It does look like a lot of schools took advantage of it [the closing of facilities],” Brent Kynoch, managing director of the Environmental Information Association, told The Mesothelioma Center at Asbestos.com. “They may have had work contracted for later in the summer, but just said, ‘Let’s get started with it now, and get it done.’ They understood the im...

This study aims to evaluate micronuclei (MN) frequency as a biomarker of genome instability in peripheral blood lymphocytes of PM and lung cancer (LC) patients when compared with healthy controls (HCs) and patients with nonneoplastic respiratory diseases (RDs). Lymphocyte cytokinesis-block MN assay was carried out on 317 subjects. Mutagen sensitivity, measured by quantifying MN frequency after an in vitro challenge with ionizing radiation, was evaluated in 252 subjects. A significant increase in MN frequency was observed in cancer patients compared to HCs, with a mean ratio (MR) of 1.35 and 1.36 at baseline and 1.43 and 1....
