Title: A multihazard, multistrategy approach to home remediation: Results of a pilot study

Abstract

Many residential hazards are disproportionately concentrated in older, urban dwellings and share common underlying causes, such as uncorrected moisture problems and inadequate maintenance and cleaning. Comprehensive and affordable approaches to remediation are needed, but the feasibility and efficacy of such approaches has not been well documented. To address this gap, a multihazard, multimethod intervention, addressing deteriorated lead-based paint and lead dust, vermin, mold, and safety hazards was pilot-tested in a sample of 70 pre-1940 dwellings. Dwellings received paint stabilization, dust lead cleaning, integrated pest management (IPM), mold cleaning, and safety devices, as needed. The median remediation cost for labor and materials was $864.66 (range: $120.00-5235.33) per dwelling. Environmental conditions were evaluated prior to, immediately following, and an average of 5 months after remediation. Between the baseline and 5-month follow-up periods, significant reductions were achieved in the number of dwellings with multiple (i.e., three or four) problems (75% vs. 23%, P<0.0001); high levels of dust lead on floors and window sills (67% and 46% declines, P<0.01); evidence of cockroaches or rodents (43% and 36% declines, P<0.01); and fire, electrical and/or fall hazards (between 67% and 88% declines, P<0.01). Significant reductions were also observed in the geometric mean (GM) dust lead levelsmore » on floors and window sills (13.3 vs. 5.0{mu}g/ft{sup 2} and 210.6 vs. 81.0{mu}g/ft{sup 2}, respectively, P<0.0001) and Blatella germanica (Blag1) levels among dwellings with elevated baseline levels (7.7 vs. 0.09U/g, P<0.0001). Reductions in mold dust levels were of borderline statistical significance (50% decline, P=0.07). The greatest declines in dust lead and Blag1 levels occurred in dwellings having the highest baseline levels and, for Blag1, in dwellings in which occupants attended training sessions. These results indicate that a comprehensive approach to hazard remediation can be highly effective and cost efficient and that overall improvements can be maintained. Further research is needed to clarify the most effective sampling strategies, educational and behavioral interventions, and optimal intervention frequency. y.« less

  • A full-scale, one-year pilot study of a new design of air sparging system is being conducted at a site in the Midwest where plumes of TCE-contaminated ground water have been identified in an unconfined sand and gravel aquifer in which ground water flows at approximately 0.5 feet/day. TCE concentrations in the ground water range up to several thousand {micro}g/L. A horizontal sparging well and associated soil vapor extraction (SVE) system have been constructed perpendicular to a contaminant plume immediately downgradient from its source. In addition, a vertical sparging well and SVE system have been constructed at the source to acceleratemore » volatilization of TCE from the soil and ground water in the area of greatest contamination. All 24 SVE wells installed for the study are vertical. Although sparging from horizontal wells has been shown to be effective at other sites, this pilot study represents the first time to the authors knowledge that a horizontal sparging well has been oriented perpendicular to the ground water flow direction in order to intercept a contaminant plume. In this design, the horizontal air sparging well takes advantage of the natural ground water flow to maximize its zone of influence. Preliminary data from a network of 24 ground water monitoring wells and 15 vadose zone monitoring wells show that for a given air sparing flow rate, the radius of influence (lateral distance air travels through the aquifer) of the horizontal well is significantly greater than the radius of influence of the vertical well, although both wells are screened in similar sediments at the same depth below the water table.« less
  • Air sparging (AS) and soil vapor extraction (SVE) are two methods used to recover hydrocarbons from vadose zone and ground water. Air sparging and soil vapor extraction also introduce oxygen to the ground water and the vadose zone which may enhance the biodegradation of hydrocarbons in the subsurface. The basic AS/SVE trench system design at the subject site consists of a horizontal section of air sparging pipe within the remediation trench. Compressed air is forced into the remediation trench through a 1-inch slotted PVC pipe. The air passes through the ground water, effectively stripping volatile organic hydrocarbons from the water.more » The volatile organics are removed and discharged to the atmosphere utilizing vapor extraction wells placed adjacent to or within the remediation trench. Because the behavior of the contaminants and the soil characteristics can change from site to site, it is common to perform a pilot test using equipment to simulate the actual conditions which will be encountered. The pilot test results are used to predict the equipment requirements and performance specifications.« less
  • Purpose: The aim of this pilot study was to assess the clinical benefit of proton beam therapy for mucosal melanoma of the head and neck. Methods and Materials: Patients with mucosal melanoma of the head and neck with histologically confirmed malignant melanoma and N0 and M0 disease were enrolled. Proton therapy was delivered three times per week with a planned total dose of 60 Gy equivalents (GyE) in 15 fractions. Results: Fourteen consecutive patients were enrolled from January 2004 through February 2008. Patient characteristics were as follows: median age 73 years old (range, 56 to 79 years); male/female ratio, 7/7;more » and T stage 1/2/3/4, 3/2/0/9. All patients were able to receive the full dose of proton therapy. The most common acute toxicities were mucositis (grade 3, 21%) and mild dermatitis (grade 3, 0%). As for late toxicity, 2 patients had a unilateral decrease in visual acuity, although blindness did not occur. No treatment-related deaths occurred throughout the study. Initial local control rate was 85.7%, and, with a median follow-up period of 36.7 months, median progression-free survival was 25.1 months, and 3-year overall survival rates were 58.0%. The most frequent site of first failure was cervical lymph nodes (6 patients), followed by local failure in 1 patient and lung metastases in 1 patient. On follow-up, 5 patients died of disease, 4 died due to cachexia caused by distant metastases, and 1 patient by carotid artery perforation cause by lymph nodes metastases. Conclusions: Proton beam radiotherapy showed promising local control benefits and would benefit from ongoing clinical study.« less
  • In 2004 the European Commission and Member States initiated activities towards a harmonized approach for Human Biomonitoring surveys throughout Europe. The main objective was to sustain environmental health policy by building a coherent and sustainable framework and by increasing the comparability of data across countries. A pilot study to test common guidelines for setting up surveys was considered a key step in this process. Through a bottom-up approach that included all stakeholders, a joint study protocol was elaborated. From September 2011 till February 2012, 17 European countries collected data from 1844 mother–child pairs in the frame of DEMOnstration of amore » study to COordinate and Perform Human Biomonitoring on a European Scale (DEMOCOPHES). Mercury in hair and urinary cadmium and cotinine were selected as biomarkers of exposure covered by sufficient analytical experience. Phthalate metabolites and Bisphenol A in urine were added to take into account increasing public and political awareness for emerging types of contaminants and to test less advanced markers/markers covered by less analytical experience. Extensive efforts towards chemo-analytical comparability were included. The pilot study showed that common approaches can be found in a context of considerable differences with respect to experience and expertize, socio-cultural background, economic situation and national priorities. It also evidenced that comparable Human Biomonitoring results can be obtained in such context. A European network was built, exchanging information, expertize and experiences, and providing training on all aspects of a survey. A key challenge was finding the right balance between a rigid structure allowing maximal comparability and a flexible approach increasing feasibility and capacity building. Next steps in European harmonization in Human Biomonitoring surveys include the establishment of a joint process for prioritization of substances to cover and biomarkers to develop, linking biomonitoring surveys with health examination surveys and with research, and coping with the diverse implementations of EU regulations and international guidelines with respect to ethics and privacy. - Highlights: • A common European Human Biomonitoring (HBM) survey protocol was developed through a bottom-up approach. • A joint process for prioritization was established to select a limited set of biomarkers, some covered by experience and others for emerging substances. • The protocol was tested in a pilot study, resulting in HBM results comparable on a European scale which sustained environmental health policy. • Ethics and privacy regulations were not an obstacle for transnational harmonization.« less
