Umann, Juliane;Guido, Laura de Azevedo;Grazziano, Eliane da Silva;
Revista Latino-Americana de Enfermagem , 2012, DOI: 10.1590/S0104-11692012000100021
Abstract: this quantitative, descriptive, cross-sectional research aimed to determine the estimated productivity of health-related limitations at work in 129 nurses working in direct care delivery to critical and potentially critical patients. instruments were applied for socio-demographic and functional characterization and for the evaluation of presenteeism (work limitations questionnaire). statistical package for the social sciences software was used for data analysis. in this study, 75% of nurses obtained a lost productivity index of up to 4.84%. the physical demand domain represented the major limitation for these professionals (25%). presenteeism was directly correlated to health care, occurrence and number of absences, and indirectly related to work time at the unit. it was concluded that organizational or individual factors influence individuals' productivity, in view of the circumstances involving care delivery to critical and potentially critical patients.

Abstract: Measurements of atmospheric volatile organic compounds were performed in the Finnish Boreal forest atmosphere during spring 2003, as part of the project QUEST (Quantification of Aerosol Nucleation in the European Boundary Layer), using a ground-based Chemical Ionization Mass Spectrometer (CIMS) instrument. Based on the study of their hydrate distribution, methanol, acetonitrile, acetaldehyde, dimethyl amine (DMA), ethanol/formic acid, acetone, trimethyl amine (TMA), propanol/acetic acid, isoprene, methyl vinyl ketone (MVK) and metacrolein (MaCR), monoterpenes and monoterpene oxidation product (MTOP) are proposed as candidates for masses 32, 41, 44, 45, 46, 58, 59, 60, 68, 70, 136, and 168amu, respectively. It would be, to our knowledge, the first time DMA, TMA and MTOP are measured with this method. Most compounds show a clear diurnal variation with a maximum in the early night, corresponding to the onset of the noctural inversion and in agreement with independant measurements of CO. Biogenic compounds are highly correlated with each other and the ratio monoterpene/oxidation product shows a typical daily pattern of nightime maxima. However, because isoprene mixing ratios are also maximum during the early night, it is likely that it suffers of the interference from another unidentified biogenic compound. Hence mass 68amu is identified as isoprene+compound X.

Abstract: Biogenic VOCs are important in the growth and possibly also in the early stages of formation of atmospheric aerosol particles. In this work, we present 10 min-time resolution measurements of organic trace gases at Hyyti l , Finland during March 2002. The measurements were part of the project QUEST (Quantification of Aerosol Nucleation in the European Boundary Layer) and took place during a two-week period when nucleation events occurred with various intensities nearly every day. Using a ground-based Chemical Ionization Mass Spectrometer (CIMS) instrument, the following trace gases were detected: acetone, TMA, DMA, mass 68amu (candidate=isoprene), monoterpenes, methyl vinyl ketone (MVK) and methacrolein (MaCR) and monoterpene oxidation products (MTOP). For all of them except for the amines, we present daily variations during different classes of nucleation events, and non-event days. BVOC oxidation products (MVK, MaCR and MTOP) show a higher ratio to the CS on event days compared to non-event days, indicating that their abundance relative to the surface of aerosol available is higher on nucleation days. Moreover, BVOC oxidation products are found to show significant correlations with the condensational sink (CS) on nucleation event days, which indicates that they are representative of less volatile organic compounds that contribute to the growth of the nucleated particles and generally secondary organic aerosol formation. Behaviors of BVOC on event and non event days are compared to the behavior of CO.

The measurements were part of the project QUEST (Quantification of Aerosol Nucleation in the European Boundary Layer) and took place during a two-week period when nucleation events occurred with various intensities nearly every day.

For all of them except for the amines, we present daily variations during different classes of event days, and non-event days. Isoprene, monoterpenes, MVK+MaCR, cis-3-hexenyl acetate and MTOP are found to show significant correlations with the condensational sink (CS), which indicates that a fraction of these compounds are participating to the growth of the nucleated particles and generally secondary organic aerosol formation. Moreover, the terpene oxidation products (TOP) (MVK, MaCR and MTOP) show a higher ratio to the CS on event days compared to non-event days, indicating that their abundance relative to the surface of aerosol available is higher on nucleation days.

Based on the study of their hydrate distribution, Methanol, Acetonitrile, Acetaldehyde, Dimethyl Amine (DMA), Ethanol/Formic Acid, Acetone, Trimethyl Amine TMA, Propanol/Acetic Acid, Methyl Vinyl Ketone (MVK) and Metacrolein (MaCR), Monoterpenes, Cis-3-hexenyl Acetate and Monoterpene Oxidation Products (MTOP) are proposed as candidates for masses 33, 41, 44, 45, 46, 58, 59, 60, 70, 136, 142 and 168 amu, respectively. It would be, to our knowledge, the first time DMA, TMA, MTOP and Cis-3-hexenyl Acetate are measured with this method. A compound with mass 68 amu, which could be Isoprene has also been identified. Most compounds show a clear diurnal variation with higher concentrations at night, starting at the onset of the nocturnal inversion and in agreement with independent measurements of CO. Biogenic compounds are highly correlated with each other and the ratio monoterpene/oxidation product shows a typical daily pattern of nighttime maxima. Cis-3-hexenyl Acetate has a diurnal variation similar to the ones of Isoprene and Monoterpenes, and especially close to the diurnal variation of their oxidation products.

Abstract: The EU-project MINATROC (MINeral dust And TROpospheric Chemistry) aims at enabling an estimation of the influence of mineral dust, a major, but to date largely ignored component of tropospheric aerosol, on tropospheric oxidant cycles. Within the scope of this project continuous atmospheric measurements of gas-phase HNO3 and SO2 were conducted in June and July 2000 at the CNR WMO station, situated on Monte Cimone (MTC) (44°11' N --10°42' E, 2165 m asl), Italy. African air transporting dust is occasionally advected over the Mediterranean Sea to the site, thus mineral aerosol emitted from Africa will encounter polluted air masses and provide ideal conditions to study their interactions. HNO3 and SO2 were measured with an improved CIMS (chemical ionization mass spectrometry) system for ground-based measurements that was developed and built at MPI-K Heidelberg. Since HNO3 is a very sticky compound special care was paid for the air-sampling and background-measurement system. Complete data sets could be obtained before, during and after major dust intrusions. For the first time these measurements might provide a strong observational indication of efficient uptake of gas-phase HNO3 by atmospheric mineral-dust aerosol particles.
