Research paper thumbnail of PM 2.5 characterization for time series studies: Organic molecular marker speciation methods and observations from daily measurements in Denver

Atmospheric Environment, 2009

Many studies have identified associations between adverse health effects and short-term exposure ... more Many studies have identified associations between adverse health effects and short-term exposure to particulate matter less than 2.5 mm in diameter (PM 2.5 ). These effects, however, are not consistent across geographical regions. This may be due in part to variations in the chemical make-up of PM 2.5 resulting from unique combinations of sources, both primary and secondary, in different regions. The Denver Aerosol Sources and Health (DASH) study is a multi-year time series study designed to characterize the daily chemical composition of PM 2.5 in Denver, identify the major contributing sources, and investigate associations between sources and a broad array of adverse health outcomes. Measurement methodology, field blank correction, pointwise uncertainty estimation and detection limit consideration are discussed in the context of bulk speciation for the DASH study. Results are presented for the first 4.5 years of mass, inorganic ion and bulk carbon speciation. The derived measurement uncertainties were propagated using the root sum of squares method and show good agreement with precision estimates derived from bi-weekly duplicate samples collected on collocated samplers. Gravimetric mass has the most uncertainty of any measurement and reconstructed mass generated from the sum of the individual species shows less uncertainty than measured mass on average. The methods discussed provide a good framework for PM 2.5 speciation measurements and are generalizable to analysis of other environmental measures.

Assessments included intelligence, achievement, memory, and executive functioning measures. Group differences were found on all tests (p < .001). Planned comparisons revealed differences between BA and A on seven variables, and between A and AA on five variables with small-to-medium effect sizes. Correlations were found between IQ and neuropsychological functioning and varied by group membership. In children, IQ predicts neuropsychological performance differentially based upon ability level, with stronger relationships shown in lower IQ ranges.

This study examined mild-moderate TBI patients, Alzheimer's Dementia patients, and Psychiatric controls on MMPI-2 scales. Participants included 160 outpatients (TBI n = 26, AD n = 74, Psychiatric n = 60). Controlling for family-wise-error, five ANCOVAs were conducted on five MMPI-2 scales, correcting for age and education. TBI and Psychiatric group means were significantly higher than AD group means for scales Hypochondriasis, Depression, and Hysteria at an alpha of .01. Results support previous research with mild TBI patients, and further document a unique pattern of elevations in this population.
