• Translocation and bioaccumulation of metals in Oryza sativa and Zea mays growing in chromite-asbestos contaminated agricultural fields, Jharkhand, India. A. Kumar, S.K. Maiti. 2014;93(4):434-41. PubMed · Publisher

  Abstract

  The present study involves the assessment of metals (Cr, Ni, Pb and Cd) in contaminated agricultural soil (CAS) and abandoned chromite-asbestos waste (CW). High concentrations of Cr and Ni were found in CW (1,121-2,802 mg Cr kg(-1); 985-1,720 mg Ni kg(-1)), which CAS (1,058-1,242 mg Cr kg(-1); 1,002-1,295 mg Ni kg(-1)). Zea mays and Oryza sativa showed significant amounts of metals in root and aerial parts. The primary factors only consider the changes in metal concentrations in soil and plant, while dynamic factor includes both changes in metal concentration and environmental processes. In spite of the high concentration of Cr present in contaminated soils and crops, significant translocation of metals (>1) were found only for Pb and Ni, when primary factor was used. When dynamic factor was used, higher translocation (>1) and bioaccumulation (>1) were found for Cr along with Pb and Ni. The current study concludes that assessment of metal toxicity in CAS and crops could be better evaluated by using both primary and dynamic factors.

• Personal and static sample measurements of asbestos fibres during two abatement projects. A. Dufresne, C. Dion, A. Frielaender, et al. 2009;82(4):440-3. PubMed · Publisher

  Abstract

  Exposure assessment was performed during the abatement of amosite containing material (ACM) and chrysotile containing material (CCM). Mean fibre concentrations (MFC) in breathing zone (BZ) were 20.6+/-7.9 f/cc and 6.3+/-2.2 f/cc during abatements of ACM and CCM, respectively. At the fixed station, MFC were 5.4+/-3.5 f/cc for ACM and 2.9 f/cc+/-1.6 for CCM. For observer's BZ, MFC were 3.1+/-1.3 f/cc (ACM) and 1.8 f/cc (CCM) during the abatement. Though elevated, area and observer-type samples clearly underestimate exposure. Exposure remained unacceptable in the worksite with the class of respiratory protection used.

• Exposure to airborne asbestos during abatement of ceiling material, window caulking, floor tile and roofing material. J.H. Lange, S.L. Sites, G. Mastrangelo, et al. 2008;80(1):10-3. PubMed · Publisher

  Summary

  The authors measured airborne asbestos during abatement of several types of asbestos-containing material because they considered published exposure data for this industry limited. The removal work took place in schools in the eastern United States in 2000. Project A and Project B involved floor tile and mastic. Project C involved roofing, window caulking and ceiling or wall plaster. The materials contained more than 1% asbestos by polarized light microscopy. Personal, 30-minute excursion, perimeter and background air samples were collected on mixed cellulose ester filters and analysed by phase contrast microscopy. Final clearance samples were analysed by transmission electron microscopy. Results were compared with the OSHA permissible exposure limit (0.1 f/cc time-weighted average) and excursion limit (1.0 f/cc over 30 minutes). All exposures, including the highest single measurement, were below both limits, and most samples were below detection limits. Plaster removal gave the highest levels: personal samples had an arithmetic mean of 0.02 f/cc (range <0.01–0.05), and excursion samples had a mean of 0.09 f/cc (range <0.08–0.24). The estimated probability of overexposure was below 5% for all projects, except for personal exposure during plaster work, where it was about 20%. All work areas passed final clearance. The authors concluded that these activities posed no 'significant' risk of asbestos disease. They argued that caulking, roofing and floor tile/mastic should not be regulated as asbestos-containing material, that abatement is over-regulated, and that resources would be better spent on smoking prevention.

  Summary

  This study examined airborne asbestos concentrations during the abatement of floor tile and mastic, and whether area and personal air samples were related. Area and personal samples were collected during a 1997 abatement project in a three-story dormitory-type building in Pennsylvania, USA, covering 25,000 square feet. Both the floor tile and the mastic contained chrysotile asbestos at 3-7%. Floor tile was removed by scrape and lift, and mastic by chemical solvent. Controls included negative air machines, polyethylene barriers and a three-stage decontamination station. Abatement activities, including setup and final air clearance, lasted about 20 days. An independent technician collected samples with low-flow pumps. Samples were analyzed by phase contrast microscopy (NIOSH method 7400) and reported as actual and time-weighted average (TWA) concentrations. Four personal samples and one area sample were below the detection limit. All TWA and non-TWA measurements were below the OSHA Permissible Exposure Limit. Both sample types fitted a logarithmic distribution. The highest values (area 0.067 f/cc, personal 0.094 f/cc) were outliers. Personal samples were statistically higher than area samples, with and without outliers, and the two methods were not correlated. The authors concluded that area samples cannot be used in place of personal measurements. They stated that this type of abatement results in exposures below the OSHA limit of 0.1 f/cc-TWA, that the data do not support respirator use, and that limited control measures would appear appropriate.

• Transplacental transfer of asbestos in pregnant mice. A.K. Haque, D.M. Vrazel. 1998;60(4):620-5. PubMed · Publisher

  Summary

  Earlier human studies had found asbestos fibers in the tissues and placentas of stillborn infants. The authors therefore investigated whether asbestos fibers cross the placenta in pregnant mice. The work was done at the University of Texas Medical Branch, Galveston. Pregnant ICR mice received crocidolite asbestos suspension (approximately 345,000 fibers/ml) by tail vein injection. On gestational day 12, two mice received 0.2 ml and one received 0.45 ml. On gestational day 16, one more mouse received 0.2 ml. One control mouse received 0.2 ml of normal saline on gestational day 15. Mice were sacrificed 1, 48 or 72 hours after treatment, and fetuses and placentas were removed by Caesarean section. In total, 36 fetuses and their placentas from 5 mice were examined. Fibers were counted by light microscopy after tissue digestion. Tissues were also examined by light microscopy for pathologic changes, and by electron microscopy with energy dispersive x-ray analysis. Average fetal counts ranged from 254 fibers/g (48 hours) to 4,288 fibers/g (1 hour). Average placental counts ranged from 5,222 to 23,529 fibers/g. Control tissues contained 0 fibers/g. Focal coagulative necrosis with mild neutrophil infiltration was seen in 29% of placentas from treated mice. Electron microscopy of necrotic placental areas showed very small (100-700 nm) fibers in the cytoplasm of placental sinusoidal cells, and a few within cell nuclei. The authors concluded that asbestos fibers transferred to the fetus and placenta within an hour of intravenous injection and remained present for up to 72 hours. They noted that the observations were based on a small number of animals.
