Burning eyes, burning lungs, skin rashes and other symptoms of illness have been found in a study of residents living near land fertilized with Class B biosolids, a byproduct of the human waste treatment process.
This study is the first linking adverse health effects in humans to the land application of Class B biosolids to be published in a medical journal. It was co-authored by David Lewis, a UGA research microbiologist also affiliated with the U.S. Environmental Protection Agency (EPA)s National Exposure Research Laboratory; David Gattie, assistant professor of agricultural engineering at the University of Georgias College of Agricultural and Environmental Sciences; Marc Novak, a research technician at UGAs School of Marine Sciences; Susan Sanchez, assistant professor of veterinary medicine at UGA; and Charles Pumphrey, a physician from Prime Care of Sun City in Menifee, Calif. The article appeared this month in the British medical journal, BMC Public Health.
Researchers found that affected residents lived within approximately one kilometer (0.6 miles) of land application sites and generally complained of irritation after exposure to winds blowing from treated fields. A prevalence of Staphylococcus aureus infections, a condition commonly accompanying diaper rash, was found in the skin and respiratory tracts of some individuals. Approximately 25 percent of the individuals surveyed were infected, and two died. The 54 individuals surveyed lived near 10 land application sites in Alabama, California, Florida, New Hampshire, Ohio, Ontario, Pennsylvania and Texas. S. aureus is commonly found in the lower human colon and tends to invade irritated or inflamed tissue.

The well-known representation of chemical elements is just one example of how objects can be arranged and classified
The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...
Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...
Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.
The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
Researchers at Chalmers University of Technology, Sweden, have discovered a completely new way of capturing, amplifying and linking light to matter at the nanolevel. Using a tiny box, built from stacked atomically thin material, they have succeeded in creating a type of feedback loop in which light and matter become one. The discovery, which was recently published in Nature Nanotechnology, opens up new possibilities in the world of nanophotonics.
Photonics is concerned with various means of using light. Fibre-optic communication is an example of photonics, as is the technology behind photodetectors and...
