Toshishige M. Suzuki and his colleagues at the Tohoku Center of National Institute of Advanced Industrial Science & Technology (AIST; Sendai, Japan; edlinks.chemengonline.com/5827-538) has developed a new analytical test strip that can quickly detect parts-per-billion (ppb) concentrations of heavy metal…
Fuel costs rose sharply in 2005 because of hurricane damage to U.S. interests in the Gulf of Mexico, and international developments in the oil supply market. Competing fuels — coal and natural gas — rose in price in…
The presence of arsenic minerals, such as enargite and tennantite, in some copper-bearing ore bodies, can be a problem for those wishing to recover the copper. When delivering copper concentrates to smelters in Australia, for example, miners are subjected to…
Last August, the comments on this page saluted recent achievements of BASF Corp., Merck, Archer Daniels Midland and other winners of the U.S.’s 2005 Presidential Green Chemistry Challenge Program, administered by the Environmental Protection Agency (Green-chemistry feats bring in the…
Phosgene is widely used for making fine chemicals, pharmaceutical intermediates, and polymers such as isocyanates, polyurethanes and polycarbonates. But phosgene is highly toxic, and although gas detectors are required to monitor for dangerous leaks, they cannot determine if workers have…
A direct link between the size of particles and their potential for causing health problems is what has the U.S. Environmental Protection Agency (EPA; Washington, D.C.; epa.gov) concerned about particulate matter (PM) that is 10µm in diameter or…
