Bioaccumulation of heavy metals has been studied in aquatic flora and fauna to a greater extent than in terrestrial animals. Hence, this study was performed to find out whether lead was excreted in the milk of buffaloes reared near the Cooum belt which was fed by contaminated feed and polluted water from the nearby wells. The concentrations of lead in milk of buffaloes fed under farm conditions...

Please cite this article in press as: Ayotte, J.D., trace elements at water-supply wells. Appl. Geo The effects of human-induced alteration of groundwater flow patterns on concentrations of naturallyoccurring trace elements were examined in five hydrologically distinct aquifer systems in the USA. Although naturally occurring, these trace elements can exceed concentrations that are considered ha...

Recent studies on the contamination of groundwater with human enteric viruses have focused on public water systems, whereas little is known about the occurrence of viruses in private household wells. The objective of the present study was to estimate the incidence of viruses in Wisconsin household wells located near septage land application sites or in rural subdivisions served by septic system...

A 19-year-old white man was referred to the pulmonary clinic with a 2-month history of refractory cough, low-grade fevers, night sweats, and 30-lb weight loss. He had right-sided pleuritic pain and episodic scant hemoptysis. He denied smoking and using illicit drugs. He was single and had protected sex with two female partners over the past several years. He worked as a pipe fitter and denied a...

Wells turbine is a self-rectifying air turbine which is widely used in oscillating water column energy converter. The Wells turbine will always rotate in the same direction irrespective of the direction of the oscillating airflow. Furthermore the Wells turbine has a simple configuration and structure. This is why the Wells turbine is very commonly used for conversion of wave energy. At present ...

Abandoned oil and gas wells provide a potential pathway for subsurface migration and emissions of methane and other fluids to the atmosphere. Little is known about methane fluxes from the millions of abandoned wells that exist in the United States. Here, we report direct measurements of methane fluxes from abandoned oil and gas wells in Pennsylvania, using static flux chambers. A total of 42 an...

Recent studies in northeastern Pennsylvania report higher concentrations of dissolved methane in domestic water wells associated with proximity to nearby gas-producing wells [ Osborn et al. Proc. Natl. Acad. Sci. U. S. A. 2011 , 108 , 8172 ] and [ Jackson et al. Proc. Natl. Acad. Sci. U. S. A. , 2013 , 110 , 11250 ]. We test this possible association by using Chesapeake Energy's baseline data s...

sufficiently large that submarkets are apparent. Eagles (1995a) suggests, using a motive-based methodology for segmentation, that the nature-tourism market contains at least four recognizable niche markets: ecotourism, wilderness use, adventure travel, and car camping. Ecotourism involves travel for the discovery of and learning about wild, natural environments. Wilderness travel involves perso...
