The explosion and collapse of the World Trade Center (WTC) was a catastrophic event that produced an aerosol plume impacting many workers, residents, commuters during first few days after 11 September 2001. Three bulk samples total settled dust smoke were collected at weather-protected locations east WTC on 16 17 2001; these are representative generated material immediately fire concurrent two structures. We analyzed each sample, not differentiated by particle size, for inorganic organic...
Although the presence of polybrominated diphenyl ethers (PBDEs) in house dust has been linked to consumer products, mechanism transfer remains poorly understood. We conjecture that volatilized PBDEs will be associated with particles containing organic matter and homogeneously distributed dust. In contrast, arising from weathering or abrasion polymers should remain bound original polymer matrix heterogeneously within used scanning electron microscopy other tools environmental forensic...
Cosmetic talcum powder products have been used for decades. The inhalation of talc may cause lung fibrosis in the form granulomatose nodules called talcosis. Exposure to has also suggested as a causative factor development ovarian carcinomas, gynecological tumors, and mesothelioma.To investigate one historic brand cosmetic associated with mesothelioma women.Transmission electron microscope (TEM) formvar-coated grids were prepared concentrations directly, on filters, from air collections...
Abstract The collapse of the World Trade Center (WTC) on September 11, 2001, generated large amounts dust and smoke that settled in surrounding indoor outdoor environments southern Manhattan. Sixteen samples were collected from undisturbed locations inside two uncleaned buildings adjacent to Ground Zero. These analyzed for morphology, metals, organic compounds, results compared with previously reported WTC dust/smoke results. We also seven additional provided by residents local...
A review of the results over 1500 asbestos analyses from U.S. water supplies suggests that majority consumers are not exposed to concentrations in their drinking 1 x 10(6) fibers per liter. There are, however, some populations waterborne 10 liter caused by natural erosion, mine processing wastes, waste pile corrosion cement pipe, or disintegration tile roofs running into cisterns. The distribution fiber sizes is dependent on source fibers. average length chrysotile found an system was 4...
The review of available data on the concentrations asbestos in U.S. water supplies suggests that majority consumers are not exposed to over 1 million fibers/Liter. A few populations, however, may be billion fibers/L. Of 538 for which waterborne available, 8% have fibers 10 vast found under 5 micron length.
That corrosion caused by aggressive water not only carries the threat of distribution system deterioration but also poses a potential health hazard is generally recognized. But just how widespread problem? And serious? A national survey covering suppliers serving approximately one fifth US population shows almost 70 percent representative utilities to have moderately highly waters.
Cancer mortality for the population census tracts of Escambia County, FL, which use asbestos-cement (AC) pipe public potable water distribution, was compared with cancer data collected from in same county where other types piping materials are used. An analysis covariance run to test differences standard ratios seven sites among three potential asbestos exposure groups based on AC usage. Twelve variables representing nonexposure-related influences disease rates were combined four independent...
Laser-ablation sector field inductively coupled plasma mass spectrometry (ICP-MS) has been used for the in situ determination of concentrations and isotope compositions Pb an environmental sample a form layered paint chip. This study examines feasibility using powerful method ratio analysis laser ablation ICP-MS as routine rapid, but very reliable, analytical instrument fingerprinting sources lead forensic investigations. Significant were found four six layers chip sample. The analyzed...
Several studies were designed and conducted to evaluate amphibole asbestos exposures in homes containing Zonolite (expanded vermiculite) attic insulation (ZAI). A range of tasks selected for evaluation included cleaning, working around, moving, removal ZAI attics living spaces. The fieldwork these was at two Spokane, WA one home Silver Spring, MD. Personal area air samples collected analyzed as part the exposure studies. Surface dust bulk also analyzed. results demonstrated that airborne...
Asbestos‐cement pipe has had a reputation for resisting attack by aggressive waters that cause corrosion of metal materials. The results this study suggest asbestos–cement behaves much like other piping materials, except PVC, are commonly used potable water distribution.
Installing cable above a suspended ceiling in the presence of asbestos-containing fireproofing is an example activity that may disturb in-place asbestos and associated dust debris. Two simulations installation were conducted room unoccupied school to test extent such disturbance resulting elevations airborne asbestos. Average concentrations increased over 500-fold during simulations, with several samples exceeding 50 structures per cubic centimeter (s/cm3), as measured by transmission...
An earlier epidemiologic and electron microscopy study of drinking water in the Everett area Washington State indicated large numbers naturally occurring chrysotile asbestos fibers water. The purpose present was to determine whether significant fiber could be demonstrated urine donors residing that for less than 3 yr over 20 where tapwater contained about 200 X 10(6) fibers/L. A control group obtained from Seattle content 100 times less. Urine samples, filtered water, additional controls...

With the use of transmission electron microscope, asbestos fibers have been assessed in kidney cortex four groups rats previously exposed to intermediate-range feeding grade chrysotile asbestos. Newborn rats, from mothers gavaged with during pregnancy, were twice a week at dose level 50 mg/kg beginning age day 7 until their natural death or sacrifice. The divided into by age: 0-200, 200-400, 400-600 and 600-800 days. Of 20 comprising test groups, 17 positive, average fiber recovery being...
