A cross-sectional study of determinants of indoor environmental exposures in households with and without chronic exposure to biomass fuel smoke
(BMC, 2014)
Background: Burning biomass fuels indoors for cooking is associated with high concentrations of particulate matter (PM) and carbon monoxide (CO). More efficient biomass-burning stoves and chimneys for ventilation have been ...
Maternal exposure to biomass smoke and carbon monoxide in relation to adverse pregnancy outcome in two high altitude cities of Peru
(Elsevier, 2014)
Exposure to pollution from biomass fuel has been associated with low birthweight in some studies. Few studies have included exposure-response analyses. We conducted a case-control study of biomass fuel use and reproductive ...
Metal leaching, acidity, and altitude confine benthic macroinvertebrate community composition in Andean streams
(Wiley, 2014)
Andean streams drain metal-rich bedrock and are subjected to an extreme altitude gradient, which may create highly selective conditions for life. The aim of the present study was to evaluate the combined effects of metals ...

Balamuthia mandrillaris is a free living amoeba that can be isolated from soil. It is an emerging pathogen causing skin lesions as well as CNS involvement with a fatal outcome if untreated. Further, infections can sometimes ...
A cross-sectional study of differences in 6-min walk distance in healthy adults residing at high altitude versus sea level
(BMC, 2014)
Background: We sought to determine if adult residents living at high altitude have developed sufficient adaptation to a hypoxic environment to match the functional capacity of a similar population at sea level. To test ...
Natural and anthropogenic variations in atmospheric mercury deposition during the Holocene near Quelccaya Ice Cap, Peru
(American Geophysical Union, 2014)
Mercury (Hg) is a toxic metal that is transported globally through the atmosphere. Emissions of Hg from mineral reservoirs and recycling between soil/biomass, oceans, and the atmosphere are fundamental to the global Hg ...
