Leaching of perfluoroalkyl acids (PFAAs) from a local point source, a fire-fighting training area, has led to extensive contamination of a groundwater aquifer which has spread underneath part of a nearby town, Oakey, situated in the State of Queensland, Australia. Groundwater is extracted by residents from privately owned wells for daily activities such as watering livestock and garden beds. The concentration of 10 PFAAs in environmental and biological samples (water, soil, grass, chicken egg yolk, serum of horses, cattle and sheep), as well as human serum was investigated to determine the extent of contamination in the town and discuss fate and redistribution of PFAAs...

Carbon capture and storage (CCS) is a technology that counteracts climate change by capturing atmospheric emissions of CO2 from human activities, storing them in geological formations underground. However, CCS also involves major risks and side effects, and faces strong public opposition. The whereabouts of 408 potential CCS sites in Germany were released in 2011. Using detailed survey data on the public perception of CCS, this study quantifies how living close to a potential storage site affects the acceptance of CCS...

(1) Background: Vector-borne diseases are a significant public health problem in Western Australia. Mosquitoes are responsible for the transmission of a number of pathogens and may pose a serious nuisance problem. Prevention efforts in the State are multi-faceted and include physical, chemical, and cultural control methods for restricting mosquito breeding. This is less complex where breeding areas are located within public open spaces. In Australia's developed urban areas, breeding sites are, however, frequently located within private residential landholdings, where the scope of public health officials to act is constrained by law and practicality...

First introduced to Egypt in 2006, H5N1 highly pathogenic avian influenza has resulted in the death of millions of birds and caused over 350 infections and at least 117 deaths in humans. After a decade of viral circulation, outbreaks continue to occur and diffusion mechanisms between poultry farms remain unclear. Using landscape genetics techniques, we identify the distance models most strongly correlated with the genetic relatedness of the viruses, suggesting the most likely methods of viral diffusion within Egyptian poultry...

REVIEW
Daniel Calvo Carrasco, Mikel Sabater González
Backyard poultry and other commonly kept fowl species are often kept for their ability to lay eggs. Reproductive disease is common in fowl species. Despite being classified as food-producing species, they can be considered valuable pets, and the demand for adequate veterinary care is constantly increasing. The clinician should be familiar with the different abnormalities and the potential treatment options. Fowl species have been traditionally an anatomic, physiologic, and experimental model for avian medicine; however, information about treatment options is often limited and extrapolated from other species...
