TL;DR: In this paper, the distribution, composition and exposure risk of the size-segregated fungal and bacterial bioaerosols in an open landfill site in Dehradun, India were determined.

TL;DR: In this paper, Aspergillus fumigatus and mesophilic bacteria were used as the principal monitoring parameters at seven different composting facilities with different operating systems and treating a range of organic wastes.

TL;DR: In terms of workers' respiratory health, barns equipped with a solid/liquid separation system may offer better air quality than conventional buildings or barns with sawdust beds, while real-time PCR revealed nonstatistically different concentrations of total bacteria in all the studied swine confinement buildings.
Abstract: Hog production has been substantially intensified in Eastern Canada. Hogs are now fattened in swine confinement buildings with controlled ventilation systems and high animal densities. Newly designed buildings are equipped with conventional manure handling and management systems, shallow or deep litter systems, or source separation systems to manage the large volumes of waste. However, the impacts of those alternative production systems on bioaerosol concentrations within the barns have never been evaluated. Bioaerosols were characterized in 18 modern swine confinement buildings, and the differences in bioaerosol composition in the three different production systems were evaluated. Total dust, endotoxins, culturable actinomycetes, fungi, and bacteria were collected with various apparatuses. The total DNA of the air samples was extracted, and quantitative polymerase chain reaction (PCR) was used to assess the total number of bacterial genomes, as a total (culturable and nonculturable) bacterial assessment....

TL;DR: Results suggest that natural particulate matter can protect indigenous organisms from UV radiation in waters with elevated particle content, while source water with low particle counts may not be subject to this interference.

TL;DR: The early stage of textile processing seems to generate high endotoxin and bacteria contamination, and priorities should be given to occupational hygiene programs for workers at various sites in textile plants.
