...This is not the first safety scandal related to Chinese milk. In 2004, at least 13 babies died of malnutrition in Anhui province after unscrupulous producers sold milk with no nutritional value. Melamine, a nitrogen-rich compound used in plastics and fertilizers, has been used to make milk that has been watered down appear to have more protein than it actually does. The chemical was also found in Chinese pet food exported to the U.S. that was blamed for the deaths from kidney failure of thousands of cats and dogs last year. In July 2007, China executed the former head...
...Composed of nitrogen, carbon and hydrogen, the compound was invented in the 1830s by a German scientist and came into fashion as a material used to make plastics and laminates in the late 1930s. When combined with formaldehyde and exposed to extreme heat, melamine creates a moldable material that, when cooled, is virtually unbreakable and dishwasher-safe. This made it the durable dishware of choice on some U.S. Navy ships during World War II. After the war, designer Russel Wright and the St. Louis-based company Branchell, among others, developed molded dinnerware out of melamine, known as Melmac, designing sets...
...course, nothing's ever that simple in the energy business. Sasol's end product is cleaner than the average diesel fuel or gasoline, emitting less sulfur and less nitrogen when it burns, says Barrows. Coal-to-liquid plants can also be used to clean up the mountains of coal left over at old mines. But in terms of carbon emissions, Fischer-Tropsch is dirty. A sliding scale of emissions from fossil fuels, goes: coal, petroleum, methane. Coal emits the most carbon dioxide per unit of energy obtained. The resultant fuel also emits more carbon dioxide when burned...
...Living with Dead Zones According to a report published in the journal Science, the number of dead zones--areas of the ocean with oxygen levels so low that marine life can barely survive--has doubled every 10 years since the 1960s as a result of a runoff polluted with nitrogen-rich crop fertilizer. There are now more than 400 such zones--from the Gulf of Mexico to the Black Sea (see map above)--which, the report's authors say, pose as great a threat to coastal ecosystems as overfishing and habitat loss...
...best way to prevent this from happening would be to reduce the amount of nitrogen introduced into the ocean. The technology already exists to do that. If, for example, farmers in the upper part of the U.S. were given a financial incentive to plant crops like winter wheat, rather than leaving their fields fallow after the fall harvest, says marine ecologist Robert Howarth of Cornell University, much of the nitrogenous fertilizer that would normally get washed into waterways by spring thaws could instead be absorbed into winter grain crops. Measures of this sort, if uniformly implemented, could all but eliminate...
