The genus Aspergillus is one of the most prevalent regarding fungi in several highly contaminated occupational environments. goal current study was to assess prevalence spp. different settings, focusing on those where a higher load fungal contamination expected according European Agency for Safety and Health at Work. A specific protocol ensure more accurate assessment exposure proposed aimed allowing detailed risk characterization management. Two wastewater treatment plants, elevation plant,...
Organic dust and related microbial exposures are the main inducers of several respiratory symptoms. Occupational exposure to organic is very common has been reported in diverse settings. In vitro tests using relevant cell cultures can be useful for characterizing toxicity complex mixtures present air occupational environments such as dust. this study, viability inflammatory response, measured by production pro-inflammatory cytokines tumor necrosis factor-α (TNFα) interleukin-1 β (IL-1β),...
Studies on the microbiology of coffee cherries and beans have shown that predominant toxigenic fungal genera (Aspergillus Penicillium) are natural contaminants. The aim this study was to investigate distribution fungi in Coffea arabica L. (Arabica coffee) canephora var. robusta (Robusta green samples obtained from different sources at pre-roasting stage. Twenty-eight countries origin (Brazil, Timor, Honduras, Angola, Vietnam, Costa Rica, Colombia, Guatemala, Nicaragua, India, Uganda) were...
Atmospheric particles are a major environmental health risk. Assessments of air pollution related burden often based on outdoor concentrations estimated at residential locations, ignoring spatial mobility, time-activity patterns, and indoor exposures. The aim this work is to quantify impacts these factors outdoor-originated fine particle exposures school children. We apply nested WRF-CAMx modelling PM2.5 concentrations, gridded population, location data. Infiltration enrichment were...
Non-exhaust emissions from road transport include particles brake and tyre wear, surface abrasion dust resuspension. Road loads their chemical properties are heterogeneous knowledge is still scarce. This study aimed to characterise, for the first time in Lisbon, thoracic fraction of (PM10) by collecting samples directly pavements an situ resuspension chamber. The highest PM10 load (15.6 ± 8.75 mg m−2) was obtained on a cobblestone pavement, while asphalt roads mean 4.40 0.16 m−2. Emission...
Mycological contamination of occupational environments can be a result fungal spores' dispersion in the air and on surfaces. Therefore, it is very important to assess both types samples. In present study we assessed surface samples show relevance surfaces sampling complementing results obtained samples.In total, 42 settings were by analysis The divided into with high load (7 poultry farms 7 pig farms, 3 cork industries, waste management plants, 2 wastewater treatment plants 1 horse stable)...
Swine production has been associated with health risks and workers' symptoms. In Portugal, as in other countries, large-scale swine involves several activities the environment that require direct intervention, increasing exposure to organic dust. This study describes an updated protocol for assessment of occupational dust, unveil accurate scenario regarding environmental health. The particle size distribution was characterized mass concentration five different ranges (PM0.5, PM1, PM2.5, PM5,...
Organic dust is widespread in the environment including occupational settings, such as bakeries. Recently, a new collection device—the electrostatic cloth (EDC)—has been described for assessment of exposures. The aim this study was to investigate suitability EDC identifying distribution patterns and exposure concentrations particulate matter microbial contaminants fungi bacteria Twelve bakeries were selected, allowed settle 13 16 days on EDCs (a total 33 samples). Particle counts size (0.3...
The present study aims to investigate the sources of particulate pollution in indoor and outdoor environments, with focus on determining their contribution exposure children airborne matter (PM). To this end, parallel measurements were carried out for a selection 40 homes 5 schools between September 2017 October 2018. PM2.5 PM2.5-10 samples collected during five days each microenvironment (ME) analysed by X-Ray Fluorescence (XRF), determination elements, thermal-optical technique,...
This paper sought to address the prevalence of Mucorales in different indoor environments Portugal. Environmental samples (183 total) were collected at dwellings (n = 79) and workplaces (bakeries, swine farms, taxis, waste-sorting plants) 93) by passive sampling using electrostatic dust collector (EDC), air-conditioning filters, litter, and/or raw materials. Samples inoculated onto non-selective MEA DG18 media screened for antifungal drug-resistance azole-supplemented agar Sabouraud media. A...
Precise classification of acute leukemia (AL) is crucial for adequate treatment. EuroFlow has previously designed an AL orientation tube (ALOT) to guide toward the relevant panel and final diagnosis. In this study, we validated algorithm automated (database-supported) gating identification (AGI tool) cell subsets within samples stained with ALOT. A reference database normal peripheral blood (PB, n = 41) bone marrow (BM; 45) analyzed ALOT was constructed, served as a AGI tool automatically...
The presence of filamentous fungi was detected in wastewater and air collected at treatment plants (WWTP) from several European countries. aim the present study to assess fungal contamination two WWTP operating Lisbon. In addition, particulate matter (PM) data analyzed. To apply conventional methods, samples were through impaction using an sampler with a velocity rate 140 L/min. Surfaces by swabbing surfaces same indoor sites. All incubated 27°C for 5 7 d. After lab processing incubation...
Very few studies regarding fungal and particulate matter (PM) exposure in feed industry have been reported, although such contaminants are likely to be a significant contributing factor several symptoms reported among workers. The purpose of this study has characterize dust one Portuguese industry.Air surface samples were collected subject further macro- microscopic observations. In addition we other air order perform real-time quantitative polymerase chain reaction (PCR) amplification genes...
Occupational exposure to bioaerosols resulting from handling of flour dust and raw materials in bakeries is associated with health problems. The emergence azole-resistant fungal species the environment thought be related use azole fungicides cereal crops prevention postharvest spoilage. As used are commonly exposed azoles, we investigated mycobiota fungi prevalence this occupational environment. Ten Portuguese were assessed through electrostatic cloth (EDC, n = 27), settled (n 7), material...
