9/11 residential exposures: the impact of World Trade Center dust on respiratory outcomes of lower Manhattan residents
Antao VC , Pallos LL , Graham SL , Shim YK , Sapp JH , Lewis B , Bullard S , Alper HE , Cone JE , Farfel MR , Brackbill RM . Int J Environ Res Public Health 2019 16 (5) Thousands of lower Manhattan residents sustained damage to their homes following the collapse of the Twin Towers on 11 September 2001. Respiratory outcomes have been reported in this population. We sought to describe patterns of home damage and cleaning practices in lower Manhattan and their impacts on respiratory outcomes among World Trade Center Health Registry (WTCHR) respondents. Data were derived from WTCHR Wave 1 (W1) (9/2003(-)11/2004) and Wave 2 (W2) (11/2006(-)12/2007) surveys. Outcomes of interest were respiratory symptoms (shortness of breath (SoB), wheezing, persistent chronic cough, upper respiratory symptoms (URS)) first occurring or worsening after 9/11 W1 and still present at W2 and respiratory diseases (asthma and chronic obstructive pulmonary disease (COPD)) first diagnosed after 9/11 W1 and present at W2. We performed descriptive statistics, multivariate logistic regression and geospatial analyses, controlling for demographics and other exposure variables. A total of 6447 residents were included. Mean age on 9/11 was 45.1 years (+/-15.1 years), 42% were male, 45% had ever smoked cigarettes, and 44% reported some or intense dust cloud exposure on 9/11. The presence of debris was associated with chronic cough (adjusted OR (aOR) = 1.56, CI: 1.12(-)2.17), and upper respiratory symptoms (aOR = 1.56, CI: 1.24(-)1.95). A heavy coating of dust was associated with increased shortness of breath (aOR = 1.65, CI: 1.24(-)2.18), wheezing (aOR = 1.43, CI: 1.03(-)1.97), and chronic cough (aOR = 1.59, CI: 1.09(-)2.28). Dusting or sweeping without water was the cleaning behavior associated with the largest number of respiratory outcomes, such as shortness of breath, wheezing, and URS. Lower Manhattan residents who suffered home damage following the 9/11 attacks were more likely to report respiratory symptoms and diseases compared to those who did not report home damage. |
Respiratory protective equipment, mask use, and respiratory outcomes among World Trade Center rescue and recovery workers
Antao VC , Pallos LL , Shim YK , Sapp JH 2nd , Brackbill RM , Cone JE , Stellman SD , Farfel MR . Am J Ind Med 2011 54 (12) 897-905 BACKGROUND: Serious respiratory illnesses have been reported among rescue/recovery workers (RRW) following the World Trade Center (WTC) attacks. METHODS: We studied RRW enrolled in the WTC Health Registry to assess the effects of different respiratory protection equipment (RPE) types on respiratory outcomes, such as recurrent respiratory symptoms and diseases possibly associated with 9/11 exposures. We performed descriptive and multivariate analyses adjusting for demographics and exposure variables. RESULTS: A total of 9,296 RRW met inclusion criteria. The strongest predictors of using adequate RPE were being affiliated with construction, utilities or environmental remediation organizations and having received RPE training. Workers who used respirators were less likely to report adverse respiratory outcomes compared to those who reported no/lower levels of respiratory protection. CONCLUSIONS: Level of respiratory protection was associated with the odds of reporting respiratory symptoms and diseases. Training, selection, fit testing, and consistent use of RPE should be emphasized among emergency responders. Am. J. Ind. Med. (c) 2011 Wiley-Liss, Inc. |
The National Exposure Registry: history and lessons learned
Schultz MG , Sapp JH 2nd , Cusack CD , Fink JM . J Environ Health 2010 72 (7) 20-5 The National Exposure Registry (NER) was created as a comprehensive group of data repositories that sought, over time, to relate specific environmental exposures to dioxin, trichloroethylene (TCE), benzene, and trichloroethane (TCA) to registrants' health conditions. Some parts of the NER were well conceived, whereas others were not. The most important design deficiency of the NER was its inability to adequately assess exposure. This was the key missing element and the Achilles heel of the NER program. At least three other important issues were never satisfactorily resolved in the design of the NER. They were unverified self-reporting, appropriate control groups, and the use of biomarkers. The many health effects that were observed to be in excess when compared with national norms might be explained by methodological differences in data analysis and reliance on self-reported nonverified data. Creating and maintaining a population-based chemical exposure registry is a more difficult challenge than creating and maintaining an outcome registry, such as a cancer registry. |
