[Ab] Resumo:Children are exposed to toxic metals and metalloids via their diet and environment. Our objective was to assess the aggregate chronic exposure of children aged 3-6years, living in France, to As, Cd, Cr, Cu, Mn, Pb, Sb, Sr, and V present in diet, tap water, air, soil and floor dust in the years 2007-2009. Dietary data came from the French Total Diet Study, while concentrations in residential tap water, soil and indoor floor dust came from the 'Plomb-Habitat' nationwide representative survey on children's lead exposure at home. Indoor air concentrations were assumed to be equal to outdoor air concentrations, which were retrieved from regulatory measurements networks. Human exposure factors were retrieved from literature. Data were combined with Monte Carlo simulations. Median exposures were 1.7, 0.3, 10.2, 34.1, 60.3, 0.7, 0.1, 44.3, 1.5 and 95th percentiles were 4.4, 0.5, 15.8, 61.3, 98.3, 2.5, 0.1, 111.1, 2.9µg/kgbw/d for As, Cd, Cr, Cu, Mn, Pb, Sb, Sr, and V respectively. Dietary exposures dominate aggregate exposures, with the notable exception of Pb - for which soils and indoor floor dust ingestion contribute most at the 95th percentile. The strengths of this study are that it aggregates exposures that are often estimated separately, and uses a large amount of representative data. This assessment is limited to main diet and residential exposure, and does not take into account the relative bioavailability of compounds. These results could be used to help target prevention strategies.

[Ab] Resumo:The paper presents the results of a study of the qualitative composition and quantity of pollutants in atmospheric air in the course of operational wear of the road surface, braking system and tire treads of automobiles. On the basis of field research in samples ofatmospheric air ofthe city of St. Petersburg there were identified compounds of heavy metals andpolycyclic aromatic hydrocarbons (PAHs). There was established the dependence of the level of air pollution on traffic flows in locations of the city. Pollutants were shown to enter the air environment mainly in the form offine dust particles. There was justified the need for the control ofproducts of wear the road traffic complex in the hygienic assessment of the quality of ambient air ofmegalopises.

[Ab] Resumo:There are considered features of disorders of the immune response in chronic exposure to dust aerosols. The detected changes of indices of the immune status of employees of the dust dangerous occupations and patients with chronic dust pathology of the lungs were unidirectional in the character, which is probably caused by manifestations of nonspecific response of the immune system to the dust factor. The deterioration of cellular immunity, humoral immunity and cytokine profile predisposes to the occurrence of immunopathologic states, contributing to the development of caused by both worksite and occupation pathology.

[Ab] Resumo:There was made an evaluation of the functional state of peripheral blood neutrophils in 230 workers with dustbreathing risks (mine, metallurgical and machine-building works). There was noted the change in the responsiveness of neutrophils in dependence on both composition and the intensity of the exposure of industrial aerosols to the human body. There was followed the relation between the pathology of the respiratory system with the biochemical changes of granulocytes. These data can be used for the assessment of the nonspecific body resistance in the development of dust lung diseases.

[Ab] Resumo:Dust is a mixture of natural and anthropogenic particles originated from multiple sources, which can represent an hazard for human health. Playgrounds are a site of particularly concern, due to sand dust ingestion by toddlers and inhalation. In this study, 37 sands used in public playgrounds in the city of Barcelona were physico-chemically characterized also in relation to routine maintenance activities such as disinfection and sand renewal. The analyzed sands show a felsic mineralogy dominated by Na-feldspar, quartz, and, to a lesser extent, K-feldspar, with minor amounts of clay minerals, carbonates and hematite. Particle fractions below 10, 2.5 and 1 µm represent, on average, 0.65%, 0.17% and 0.07% of bulk volume, respectively, although, due to the human grinding, these initial fractions increased every year by a 18%, 5% and 2% respectively. Disinfection of sands effectively reduced only the NH concentration, among inorganic species. The average metal content was anthropogenically enriched, with respect to the upper continental crust, only for Sb and As. Both elements show high spatial variation indicating local sources such as road traffic for Sb (contributing mostly to the total concentration), and industry for As (also contributing with highly bioaccessible Sb, Cu and Zn). A clear inverse relationship between total concentrations of some elements and their leachable (Sb) and bioaccessible (Sb and Cr) fractions is observed. The most bioaccessible elements were Ca > Ni > Cu > Sr > Cd > Pb, all above the 25% of the total concentration. Bioaccessibility was higher for the carbonate-bearing particles and for the anthropic emitted metals (>50% of Ba, Cu, K, Pb and Zn).

[Ab] Resumo:Most studies on the adverse effects of air pollution have focused on respiratory and cardiovascular diseases, and there are relatively few studies on eye diseases following exposure of ambient particulate matter (PM). Epidemiological and clinical researches correlating the eye and PMs have recently received attention. PMs are complex mixture of particles that vary in chemical composition and size. This study investigated the influence of collected road dust on cell viability, inflammatory responses, and oxidative stress in human corneal epithelial cells. The collected road dust was classified with respect to aerodynamic diameter and solubility. Exposure concentration was calculated based on the particle deposition rate. We observed a dose-dependent decrease in cell viability at total PM and PM . The pellet fractions of total PM and PM mainly contributed to the mitochondrial activity. Although both total PM and PM did not change the membrane integrity, the supernatant fractions significantly affected cell membrane integrity. Both total and fractions induced nitric oxide production and interleukin 8 expression. In addition, total PM and PM increased the oxidative stress; the pellet fractions of total PM and PM also induced higher oxidative stress. However, there was no significant difference between the cellular responses of total PM and PM . We observed that the effects of collected road dust on cellular responses were strongly dependent on their concentration and solubility.

[Ab] Resumo:The present study effects of pollutant particles from Bartin Cement Factory on development of seeds and leaves of Taurus Cedar (Cedrus libani Rich.) which in plantation area around the factory were examined. For this purpose, seeds were collected from sampling trees located 200m, 400m, 600m, 800m and 1000m (control) and germination percentage of seeds, and total chlorophyll content of seedlings were determined. Moreover, in the present study, the air movement around Bartin Cement Factory and level of pollutants in sampling areas were also determined. The directions of the prevailing winds around the cement factory were North, and Northwest. From the aspect of pollutant material level, the array of sampling areas was SP1>SP2>SP3>SP4>C. On the other hand, evaluating the results of mean seed germination percentages, a significant difference (P<0.01) was noted between control and seeds of Taurus Cedar at various distances from are pollutant source. From the aspect of the power of seeds collected with 3 repetitions from Taurus Cedars located at various distances, it a significant difference (P<0.01) was found between the control and experimental groups. Accordingly, from both the aspects of mean germination percentage and seed power, an apparent increase was observed from 400 m distance. On the other hand, as the distance from cement factory increased, total chlorophyll content in Taurus Cedar seedlings increases significantly. Results of bilateral regression analysis evaluated exponential relationship at level 97% between these 2 variables.

[Ab] Resumo:Atmospheric pollutants including SO , NO , CO, O and inhalable particulate matter (PM and PM ) were monitored continuously from March 2014 to February 2015 to investigate characteristics of air pollution at Lhasa, Tibetan Plateau. Species exhibited similar seasonal variations except O , with the peaks in winter but low valleys in summer. The maximum O concentration was observed in spring, followed by summer, autumn, and winter. The positive correlation between O and PM in spring indicated similar sources of them, and was assumed to be turbulent transport. Temperature was the dominant meteorological factor for most species in spring. High temperature accelerates O photochemistry, and favors air disturbance which is conductive to dust resuspension in spring. Relative humidity (RH) and atmospheric pressure were the main meteorological factors in summer. RH showed negative correlations with species, while atmospheric pressure posed opposite situation. Wind speed (WS) was the dominant meteorological factor in autumn, the negative correlations between WS and species indicated diffusion by wind. Most species showed non-significant correlations with meteorological factors in winter, indicating the dependence of pollution on source emission rather than restriction by meteorology. Pollution weather character indicated that emissions were from biomass burning and dust suspension, and meteorological factors also played an important role. Air stream injection from the stratosphere was observed during O pollution period. Air parcels from Southwest Asia were observed during air pollution period in winter. An enhancement in air pollutants such as O would be expected in the future, more attention should be given to countermeasures for prevention of air pollution in the future.

[Ab] Resumo:Monazite is a naturally occurring radioactive material that is processed for use in a variety of domestic applications. At present, there is little information available on potential radiation doses experienced by people working with monazite. The ambient dose rate and activity concentration of natural radionuclides in raw materials, products, and dust in work sites as well as the Rn and Rn concentrations in work sites were measured in a monazite processing plant in Japan. Dose estimations for plant workers were also conducted. The activity concentration of the U series in raw materials and products for the monazite processing plant was found to be higher than the relevant values described in the International Atomic Energy Agency Safety Standards. The ambient dose rates in the raw material yard were higher than those in other work sites. Moreover, the activity concentrations of dust in the milling site were higher than those in other work sites. The Rn concentrations in all work sites were almost the same as those in regular indoor environments in Japan. The Rn concentrations in all work sites were much higher than those in regular indoor environments in Japan. The maximum value of the effective dose for workers was 0.62 mSv y, which is lower than the reference level range (1-20 mSv y) for abnormally high levels of natural background radiation published in the International Commission of Radiological Protection Publication 103.
