The environmental fate and bioavailability of progesterone, a steroid hormone known to cause endocrine-disrupting effects in aquatic organisms, is growing concern due its occurrence the environment water sediment influenced by wastewater treatment plant paper mill effluents, as well livestock production. objective this study was evaluate progesterone two natural sediments corresponding alteration gene expression three steroid-responsive genes; vitellogenin, androgen receptor estrogen alpha....
Thirty–six papers were published in 2009 describing new methods for analysis of veterinary pharmaceuticals, natural and synthetic steroid hormones, their occurrence agricultural settings. New continue to be developed applied toward understanding the sources environmental significance these chemicals. Advances sample preparation instrumentation provide detection limits into parts per trillion ranges. Analysis water samples indicates that many compounds do occur environment.
Abstract – Lead is a persistent and ubiquitous pollutant in urban environments of significant importance to public health. Elevated lead concentrations soil may be due the use lead-based paints, emissions from combustion leaded gasoline, industrial emissions, waste incineration, pesticide application. One potential pathway for exposure can consumption produce grown lead-contaminated soil. This increasing concern as community gardens experience resurgence popularity demand locally increases....
Household biosand filters are one point-of-use water treatment technology that can be used to provide clean drinking people living in communities without access improved supplies. There have been several studies investigating the importance of design variables on filter performance, and demonstrated improve health outcomes were they deployed. In constructing filter, it is recommended sand from a rock quarry or gravel pit as filtration sand, likely uncontaminated by waterborne pathogens....
One Health field-based approaches are needed to connect the occurrence of antibiotics present in environment with presence antibiotic resistance genes (ARGs) Gram-negative bacteria that confer important for both veterinary and human health. Water samples from two Nebraska watersheds influenced by wastewater effluent agricultural runoff were tested used medicine. The water also cultured identify present. Of those isolated, rods capable causing infections had antimicrobial susceptibility...
A pilot photovoltaic system was constructed in Kianjavato, Madagascar by a team from the University of Nebraska Engineers Without Borders-USA Student Chapter. This project represents an integrated approach to energy supply, education and natural resource conservation. The supplies power ten 13 W fluorescent tubes primary school classroom for purpose extending public hours into evening adult education. implemented partnership with Malagasy non-governmental organization, Biodiversity...
Lead is a persistent soil pollutant present in many urban environments. In 2003, 27 square mile region Omaha NE became the newest addition to National Priorities List for lead contamination. This large area encompasses 15,000 residential properties as well an community garden. Previous work performed at garden detected presence of produce. Research has shown that vegetation grown these contaminated soils can bioaccumulate and become pathway exposure humans. Although relationship between...
Abstract Background Antibiotic resistance is a significant public health threat and widespread use of antibiotics in agriculture increasing the concern about agricultural contributions to dissemination antibiotic resistant bacteria. Of level exposure antibiotic-resistant bacteria watershed. Consequently, adopting One Health approach measure levels identify gene (ARG) transfer at human, animal environmental interfaces essential better understand how spread. Methods In this project, were...
