Griffin collected dust samples in St . John, U . S . Virgin Islands, and sent them to Virginia Harrison at the agency's laboratory in St . Petersburg, Fla ., for testing.

Khalid Mustapha, deputy director of the company, said the inspectors had walked through each of the 70 rooms in their main building, taking dust samples and asking questions about the work done there.

Using dust samples, scientists analysed mean heavy metal concentrations in a Guiyu workshop and found that lead and copper were 371 and 115 times higher, respectively, compared to areas located 30 kilometres away.

The two astronauts were conducting experiments on materials for building future spacecraft . They removed samples of material mounted on the outside of the Mir by American astronauts and gathered cosmic dust samples.

Aside from the evidence of poor working practices, it was discovered that Bonsall had after the accident instructed an assistant surveyor, William Cuffin, to falsify records of dust samples when none had actually been taken.

The new push to understand comets includes NASA's Stardust, a spacecraft launched in 1999 that will fly past comet Wild 2 in 2004 to collect dust samples that will be returned to Earth in 2006.

The two astronauts were conducting experiments on materials for building future spacecraft . They were to remove some samples of material mounted on the outside of the Mir by American astronauts and gather cosmic dust samples.

The stories reported that analyses of dust samples from 31 brake repair garages in Baltimore, Boston, Chicago, Denver, Richmond, Va ., Seattle and Washington, D . C ., showed very high levels of asbestos in 21 of the sites.

The checks, performed hourly using a process called polymerase chain reaction, would bathe dust samples in enzymes that cause DNA to explosively replicate, allowing quick comparisons to a library of known DNA sequences from anthrax, bubonic plague or other pathogens.

Various dust sampling methods exist that are internationally recognised . "'Inhalable "'dust is determined using the modern equivalent of the Institute of Occupational Medicine ( IOM ) MRE 113A monitor ( see section on workplace exposure, measurement & modelling ).
