Application Of Quantum Cascade Lasers To High-Precision Atmospheric Trace Gas Measurements, Ezra Wood, J. Barry Mcmanus, Mark S. Zahniser, David D. Nelson, Joanne H. Shorter, Scott Herndon, Rick Wehr

Ezra Wood

We review our recent results in development of high-precision laser spectroscopic instrumentation using midinfrared quantum cascade lasers (QCLs). Some of these instruments have been directed at measurements of atmospheric trace gases where a fractional precision of 10−3 or better of ambient concentration may be required. Such high precision is needed in measurements of fluxes of stable atmospheric gases and measurements of isotopic ratios. Instruments that are based on thermoelectrically cooled midinfrared QCLs and thermoelectrically cooled detectors have been demonstrated that meet the requirements of high-precision atmospheric measurements, without the need for cryogens. We also describe the design of and results …

Health Impacts Of Pesticide Exposure In A Cohort Of Outdoor Workers, John R. Beard, Tim Sladden, Geoffrey Morgan, Geoffrey Berry, Lyndon O. Brooks, Anthony Mcmichael

Dr Lyndon O Brooks

We compared mortality of 1,999 outdoor staff working as part of an insecticide application program during 1935-1996 with that of 1,984 outdoor workers not occupationally exposed to insecticides, and with the Australian population. Surviving subjects also completed a morbidity questionnaire. Mortality was significantly higher in both exposed and control subjects compared with the Australian population. The major cause was mortality from smoking-related diseases. Mortality was also significantly increased in exposed subjects for a number of conditions that do not appear to be the result of smoking patterns. Compared with the general Australian population, mortality over the total study period was …

Status Of Epa’S Proposed Rule To Strengthen The Ozone Standard, Dale Stephenson

Dale J. Stephenson

On January 6, 2010 the EPA rolled out a proposal to reduce the 8-hour primary standard for tropospheric (ground level) ozone from its current level of 0.075 ppm to somewhere between 0.060 ppm and 0.070 ppm. This reduction has the potential for many US airsheds to be declared as nonattainment with the new standard (including many in the Rocky Mountain West). Such a declaration will require state regulatory agencies to initiate implementation plans to bring affected airsheds back into attainment. This presentation will summarize the current status of and reasoning for EPA’s proposed reduction to the primary ozone standard and …

Update On The Management Of Chronic Obstructive Pulmonary Disease, Andrea K. Maas, David M. Mannino

David M. Mannino

Chronic obstructive pulmonary disease is a highly prevalent, underdiagnosed, and undertreated chronic lung disease. Early and appropriate treatment may help modify the course of the disease with respect to exacerbation timing and frequency, quality of life, and mortality. Steady progress continues to be made in understanding the disease pathogenesis and treatment modalities, and there is some evidence that outcomes are improving.

Investigation Of The Correlation Between Odd Oxygen And Secondary Organic Aerosol In Mexico City And Houston, Ezra Wood, M. Canagaratna, S. Herndon, J. Kroll, T. Onasch, C. Kolb, D. Worsnop, W. Knighton, R. Seila, M. Zavala, L. Molina, P. Decarlo, J. Jimenez, A. Weinheimer, D. Knapp, B. Jobson, J. Stutz, W. Kuster, E. Williams

Ezra Wood

Many recent models underpredict secondary organic aerosol (SOA) particulate matter (PM) concentrations in polluted regions, indicating serious deficiencies in the models' chemical mechanisms and/or missing SOA precursors. Since tropospheric photochemical ozone production is much better understood, we investigate the correlation of odd-oxygen ([Ox]≡[O3]+[NO2]) and the oxygenated component of organic aerosol (OOA), which is interpreted as a surrogate for SOA. OOA and Ox measured in Mexico City in 2006 and Houston in 2000 were well correlated in air masses where both species were formed on similar timescales (less than 8 h) and not well correlated when their formation timescales or location …

Biomonitoring Studies Should Be Used By Regulatory Agencies To Assess Human Exposure Levels And Safety Of Bisphenol A, Laura Vandenberg, Ibrahim Chahoud, Vasantha Padmanabhan, Francisco Paumgartten, Gilbert Schoenfelder

Laura Vandenberg

BACKGROUND: Within the past 3 years, four major evaluations of bisphenol A (BPA) safety have been undertaken. However, these assessments have arrived at quite different conclusions regarding the safety of BPA at current human exposure levels. OBJECTIVES: We compared the reasons provided by the European Food Safety Authority (EFSA) BPA risk assessment panel for their conclusion that human exposures are negligible with the conclusions reached by the other panels, with all panels having the same body of literature at their disposal. DISCUSSION: The EFSA panel dismissed > or = 80 biomonitoring studies that documented significant levels of BPA exposure in humans, …

Everton Fernando Alves

A infecção é a mais frequente e grave complicação que acomete pacientes que procuram serviços estéticos e/ou funcionais em clínicas de cirurgia plástica. Uma infecção hospitalar eleva os custos do processo, tanto para o paciente quanto para a empresa. Diante disso, torna-se importante a instalação de uma comissão de controle de infecção hospitalar, tendo como responsável um enfermeiro. A importância deste profissional se dá por meio da organização da Central de Material Estarilizado (CME), bem como do estabelecimento de outras medidas efetivas para a prevenção e controle de infecções nas clínicas apresentadas ao longo desse artigo.

Urinary, Circulating, And Tissue Biomonitoring Studies Indicate Widespread Exposure To Bisphenol A, Laura Vandenberg, Ibrahim Chahoud, Jerrold J. Heindel, Vasantha Padmanabhan, Francisco J.R. Paumgartten, Gilbert Schoenfelder

Laura Vandenberg

BACKGROUND: Bisphenol A (BPA) is one of the highest-volume chemicals produced worldwide, and human exposure to BPA is thought to be ubiquitous. Thus, there are concerns that the amount of BPA to which humans are exposed may cause adverse health effects. Importantly, results from a large number of biomonitoring studies are at odds with the results from two toxicokinetic studies. OBJECTIVE: We examined several possibilities for why biomonitoring and toxicokinetic studies could come to seemingly conflicting conclusions. DATA SOURCES: We examined > 80 published human biomonitoring studies that measured BPA concentrations in human tissues, urine, blood, and other fluids, along with …

Recent Trends In Exposure To Secondhand Smoke In The United States Population, Chieh-I Chen, Tanya Burton, Christine L. Baker, Vera Mastey, David M. Mannino

David M. Mannino

Background Previous research using the National Health and Nutrition Examination Surveys (NHANES) data documented a significant downward trend in secondhand smoke (SHS) exposure between 1988 and 2002. The objective of this study was to assess whether the downward trend in exposure continued from 2001 through 2006.

Methods We analyzed data from the 2001-2006 NHANES to estimate exposure of nonsmokers to SHS. Geometric means of serum cotinine levels for all nonsmokers were computed.

Results Overall serum cotinine levels (95% Confidence Intervals) in 2001-2002, 2003-2004, and 2005-2006 were 0.06 ng/mL (0.05-0.07), 0.07 ng/mL (0.06-0.09), and 0.05 ng/mL (0.05-0.06), respectively. Subgroup analysis by …

David M. Mannino

Objective:

To describe the item-selection and item-reduction for the Lung Function Questionnaire (LFQ), being developed to help clinicians identify patients appropriate for diagnostic evaluation for chronic obstructive pulmonary disease (COPD) using spirometry.

Methods:

Item selection and reduction were based on information from 387 ≥40-year-old respondents to the third National Health and Nutrition Examination Survey who had self-reported chronic bronchitis. Item reduction involved stepwise logistic regression. The accuracy of the final subset of items for identifying individuals with airflow obstruction (forced expiratory volume in one second/forced vital capacity <0.70) versus those without it was assessed with receiver operating characteristic analysis. Content and face validity were assessed using focus groups of primary care physicians (n = 16) and interviews with COPD patients (n = 16).

Results:

The model with all five items (age; smoking history; the presence of …

Addressing Cancer Health Disparities Using A Global Biopsychosocial Approach, Denae W. King

Denae W King

The Center for Research on Minority Health has translated the biopsychosocial framework to address global cancer health disparities through the integration of biological (eg, endogenous steroids, genetic susceptibility, and pesticide levels) and behavioral (eg, dietary interventions) determinants, along with community-based research (eg, comprehensive involvement of community advisory boards) and educational approaches (eg, kindergarten through postgraduate training). Evidence of successful implementation of this framework includes health disparities training for >2000 individuals ranging from elementary to the postgraduate level, and conducting transdisciplinary projects that incorporate traditional and nontraditional health professionals to examine associations between biological and nonbiological determinants of health. Examples and …

A Bland–Altman Comparison Of The Lead Care® System And Inductively Coupled Plasma Mass Spectrometry For Detecting Low-Level Lead In Child Whole Blood Samples, Christina Sobin, Tanner Schaub, Natali Parisi, Eva De La Riva

Christina Sobin, Ph.D.

Chronic childhood lead exposure, yielding blood lead levels consistently below 10 μg/dL, remains a major public health concern. Low neurotoxic effect thresholds have not yet been established. Progress requires accurate, efficient, and cost-effective methods for testing large numbers of children. The LeadCare® System (LCS) may provide one ready option. The comparability of this system to the “gold standard” method of inductively coupled plasma mass spectrometry (ICP-MS) for the purpose of detecting blood lead levels below 10 μg/dL has not yet been examined. Paired blood samples from 177 children ages 5.2–12.8 years were tested with LCS and ICP-MS. Triplicate repeat tests …
