These insecticides affect the nerve synapses of insects, and neonicotinoids are popular for their solubility in water. Plants absorb the chemical, which is often applied to the soil to reduce its chances of drifting through the air. However, the solubility that makes neonicotinoids prized for controlling… Nature and Wildlife, Environment 2013-05-17T15:38:01-06:00 http://freshare.net/article/groundwater_unaffected_by_shale_gas_production_in_arkansas/ http://freshare.net/article/groundwater_unaffected_by_shale_gas_production_in_arkansas/#When:20:06:00Z A new study by scientists at Duke University and the U.S. Geological Survey (USGS) finds no evidence of groundwater contamination from shale gas production in Arkansas. “Our results show no discernible impairment of groundwater quality in areas associated with natural gas drilling and hydraulic fracturing in this region,” said Avner Vengosh, professor of geochemistry and water quality at… Nature and Wildlife, Environment 2013-05-16T20:06:00-06:00 http://freshare.net/article/decades_old_nitrate_found_to_affect_stream_water_quality/ http://freshare.net/article/decades_old_nitrate_found_to_affect_stream_water_quality/#When:18:38:00Z USGS hydrologic researchers have found that the movement of nitrate through groundwater to streams can take decades to occur. This long lag time means that changes in the use of nitrogen-based fertilizer (the typical source of nitrate) — whether the change is initiation, adjustment, or cessation — may take decades to be fully observed in streams.

Pitt researchers demonstrated that tadpoles from populations close to farm fields are more resistant to chlorpyrifos—one of the most commonly applied insecticides in the… Nature and Wildlife, Environment 2013-05-03T16:20:00-06:00 http://freshare.net/article/exposure_to_fine_traffic_pollution_particles_increases_heart_disease_risk/ http://freshare.net/article/exposure_to_fine_traffic_pollution_particles_increases_heart_disease_risk/#When:20:49:00Z Over the years, a number of studies described various associations between road traffic and heart disease. Last year, one such study even demonstrated a link between traffic noise and the probability of suffering a heart attack.

Much of this calculated excess risk results from exposures in children, age six or younger, to polycyclic aromatic hydrocarbons (PAHs) from the sealant. “The increased cancer risk associated with coal-tar-sealed asphalt (CSA)… Nature and Wildlife, Environment 2013-03-29T18:00:00-06:00 http://freshare.net/article/excess_fuel_rising_spring_temps_raise_wildfire_danger_throughout_arkansas/ http://freshare.net/article/excess_fuel_rising_spring_temps_raise_wildfire_danger_throughout_arkansas/#When:18:33:00Z Rain and snow statewide have helped drop the wildfire danger from moderate to low for most of Arkansas on Friday, but continued drought, plus deadfall from December’s ice and snow storms mean wildfire risks haven’t dropped from the radar. Howard, Little River, Montgomery, Pike, Polk, Scott, Sevier and Yell counties were all under moderate wildfire danger.

But research in atmospheric modeling by UNC Charlotte’s Amanda S. Adams and Harvard University’s David W. Keith suggests that the power capacity of large-scale wind farms may have been significantly overestimated. … Nature and Wildlife, Environment 2013-02-28T17:51:00-06:00 http://freshare.net/article/sewage_lagoons_remove_most_but_not_all_pharmaceuticals/ http://freshare.net/article/sewage_lagoons_remove_most_but_not_all_pharmaceuticals/#When:19:08:00Z 2012 marked the 40th anniversary of the Clean Water Act, which established regulations for the discharge of pollutants to waterways and supported the building of sewage treatment plants. Despite these advances, sewage remains a major source of pharmaceuticals and personal care products (PPCPs) and naturally occurring hormones found in the environment.

It is more pure and tastes better. These are a few of the common perceptions about bottled water. The fact that it is more expensive is the major divider between municipal water and most bottled water. “There is not much assurance the bottled water is better,” said Hailin Zhang, Regent’s professor of plant and soil… Nature and Wildlife, Environment 2013-02-07T17:53:00-06:00 http://freshare.net/article/the_storm_that_never_was_why_weather_predictions_go_wrong/ http://freshare.net/article/the_storm_that_never_was_why_weather_predictions_go_wrong/#When:17:49:01Z Have you ever awoken to a sunny forecast only to get soaked on your way to the office?
