We investigated the association between daily emergency ambulance calls (EAC) for elevated blood pressure that occurred during the time intervals of 8:00-13:59, 14:00-21:59, and 22:00-7:59, and exposure to CO, PM10, and ozone. We used Poisson regression to explore the association between the risk of EAC and short-term variation of pollutants, adjusting for seasonality and weather variables. Before noon, the risk was associated with an interquartile range (IQR) (7.9 μg/m(3)) increase in PM10 at lag 2-4 days below the median (RR = 1...

Ensuring hygiene and health protection is one of the basic construction requirements. Such requirements are examined when commissioning new constructions and examining defects in constructions already in use. One substantial defect is biocorrosion which represents a synergistic process with a complex variety of factors. It is caused by biochemical manifestations of various micro-organisms (micromycetes). Micromycetes producing mycotoxins therefore play an important role regarding the so-called 'Sick Building Syndrome' that has become a global problem nowadays...

To assess the importance of malaria risk factors for children in sub-Saharan African countries. 61,292 children of 16 countries from DHS and MIS surveys were included in analysis. A regression model with analyse of variance and plots of mean decrease accuracy and mean decrease Gini indices were performed. The most important risk factor was the country and it contributed 52.33 % to the variance of the model. Wealth status of the child's family was the first socio-economic factor which contributed more to the difference of malaria risk among African children...

Previously, we reported the development of a Hazard Prediction and Assessment Capability plume dispersion model of the 2005 Graniteville, South Carolina, USA accidental release of chlorine. Here, we assess this model by spatial and statistical comparison with post-incident observed environmental indicators of exposure and other types of observations. Spatial agreement was found when the model was compared to phytotoxic bleaching and corrosion events observed in 2 km radius around the release site. When spatially compared to locations of injured or killed animals, model predictions of the plume footprint were in relatively good agreement...

We aimed to develop a relevant multi-endpoint biomonitoring system by studying different genotoxicity biomarkers in complex carcinogenic exposures under occupational situations. Altogether 109 workers were followed in five different workplaces. The combined carcinogenic exposures were monitored in the urine and peripheral blood samples using Ames mutagenicity test and cytogenetic analyzes. The different genotoxicity endpoints studied showed different results in the same carcinogenic exposure situations. The urinary mutagenicity tests provided more information and proved to be more sensitive compared to the cytogenetic tests in the majority of cases...
