...found a wide range of phthalate content, from zero parts per million (ppm) to 7,300 ppm. Many air fresheners contained a phthalate known as DEP and some also contained DBP, which are listed by the California EPA's Office of Environmental Health Hazard Assessment as a developmental toxin and female and male reproductive toxin, respectively...
...early June with Chinese-made toothpaste. Following 100 deaths in Panama linked to cough syrup containing diethylene glycol (the ingredient had been mislabeled as glycerin, which is harmless), the FDA issued an import alert on all toothpaste made in China, tested the tubes it could find for the toxin and recalled the questionable batches. "Obviously it's not possible for us to test every product that is coming in to make sure it's meeting every standard we have," Acheson says. "It's got to be based on risk...
Aggressive exporters aren't easily daunted, though. The FDA, for example, strictly limits imports of puffer fish, which can contain a deadly toxin if processed improperly. After two Chicagoans got sick last month from eating what they thought was monkfish, the FDA began investigating whether a Chinese exporter had tried to sneak in puffer fish by labeling it monkfish...
...this is to confuse the bacteria, hitting them with not just one natural toxin but two. At Vertex Pharmaceuticals in Cambridge, Mass., scientists are developing a new class of antibiotics that targets a pair of enzymes the microbes depend on to copy their genes and reproduce. Adapting in two directions at once slows down the bacteria enough to give the drug time to work. "Mathematically, it becomes much harder for the bacteria to develop resistance to different targets at the same time," says Dr. John Alam, the company's chief medical officer...
...watchers: an abrupt no. There were some obvious reasons for Russian intransigence. The case is a skein of disputed plots and subplots. Lugovoi and one companion - or two, according to some versions - met Litvinenko at a London hotel on Nov. 1. Litvinenko died 22 days later from the invisible toxin apparently swallowed at that meeting. British investigators have tried to unpick the events, linking Lugovoi to a trail of particles shed by the polonium. Lugovoi denies blame, while Russia says its constitution prevents it from handing over a citizen to a foreign power...
