Suspended solids are materials that resist settling and remain suspended in water and other liquids. The ability to automatically concentrate suspended solids containing very-low concentration of microorganisms has been a troublesome task for scientists and researchers. Today this task is usually performed using Enviro-check cartridges, spending 6 hours for collection and then this process requires very complex process consisting of more than 20 steps prior to the concentrated samples of...

A new report released Monday by Britain's largest organic certification body finds that the world's supply of phosphate rock is running out faster than previously believed, posing a threat to global food security. "Intensive agriculture is totally dependent on phosphate for the fertility needed to grow crops and grass," said the Soil Association. The global supply of phosphorus from mined phosphate rock could peak as early as 2033, after which it will become increasingly costly and scarce,...

Both chemicals are found in an array of personal care products like antimicrobial soaps, and triclosan also is formulated into everyday items ranging from plastics and toys to articles of clothing.

By Jeff Harrison, University of Arizona A 19-year UA study shows that the end product of municipally treated wastewater is generally free of any pathogenic organisms that might harm humans or the environment. A newly published report from a University of Arizona research group says biosolids, properly treated, pose little if any health risk to the public. The study, "Pathogens in Biosolids: Are They Safe?," is online in the Journal of Environmental Quality. Ian L. Pepper, director of the NSF...

The red, metal-laden sludge that escaped a containment pond in Hungary last week could be made less toxic with the help of carbon sequestration, says an Indiana University Bloomington geologist who has a patent pending on the technique.The bauxite residue now covers 40 square kilometers south of the Danube River, and has caused the deaths of eight Hungarians and injured at least 150. The residue also has caused the extinction of life in a local river and as yet unknown environmental damage...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
