Subject:
agricultural soils; asbestos; chemical analysis; chromium; humans; lung neoplasms; nickel; risk; sepiolite; toxic substances
Abstract:
... The study assessed accessory minerals and metals in Tanzanian vermiculites with respect to their potential suitability for agricultural applications. Mineral and chemical analyses were involved. Pot experiments were also conducted to assess plant uptake of metals from soil with vermiculites. Fibrous sepiolite and amphiboles were minerals of health concern found in some samples. The sepiolite fiber ...

Subject:
asbestos; chemical analysis; environmental impact; heat; human health; lung neoplasms; vermiculite; Argentina
Abstract:
... Vermiculites with impurities of amphibole, a dry fine residue and calcined materials from three deposits in the province of Córdoba, Argentina, were studied. From a commercial perspective, amphiboles are considered as “asbestos”, a group of silicate minerals with strong and flexible fibres that are heat resistant and chemically inert, and thus well suited for heat insulation. These fibrous particl ...

Subject:
asbestos; insulating materials; residential housing; vermiculite
Abstract:
... The efforts of many municipalities to demolish abandoned residential dwellings (ARDs) are hampered by the presence of asbestos-containing materials (ACMs) in these structures. However, the extent of such materials is unknown. Our study sought to characterize ACMs present in ARDs demolished in Detroit.Working with the City of Detroit, we obtained information on all ARDs demolished from 2014 to 2017 ...

Subject:
asbestos; death; females; lung neoplasms; males; mesothelioma; monitoring; morbidity; mortality; public health; risk; vermiculite; Minnesota; Montana
Abstract:
... A vermiculite processing plant in a Minneapolis, Minnesota neighborhood utilized asbestos-containing ore from Libby, Montana from the late 1930's until 1989. Multiple pathways of exposure to Libby asbestos were characterized in a cohort of over 6000 plant workers and residents living near the plant.We conducted a cohort linkage study to assess the impact of cumulative low dose exposure and the rol ...

Abstract:
... Vermiculite ore containing Libby amphibole asbestos (LAA) was mined in Libby, MT, from the 1920s-1990. Recreational and residential areas in Libby were contaminated with LAA. This objective of this study was to characterize childhood exposure to LAA and investigate its association with respiratory health during young adulthood.Young adults who resided in Libby prior to age 18 completed a health an ...

Abstract:
... Libby, MT is the site of a closed vermiculite mine that produced ore contaminated with asbestos-like amphiboles. Worldwide distribution of the material and the long latency period for manifestation of asbestos-related diseases (ARDs) has created a significant health threat for many years to come. The composition of the Libby material [termed the Libby amphibole (LA)] differs from other well-studie ...

Abstract:
... The fluidized bed asbestos segregator (FBAS) is a sample preparation instrument that utilizes air elutriation to separate asbestos structures from heavier matrix particles and deposit these structures onto a filter which can then be analyzed by transmission electron microscopy (TEM) or other appropriate microscopic techniques. The performance of the FBAS preparation method was evaluated using a va ...
