Work exposures to animal neurocarcinogens.
The initiation of brain tumors has been demonstrated in animals exposed to industrial chemicals, results which have not been demonstrated in humans. This report describes the National Occupation Exposure Survey conducted by the National Institute of Occupational Safety and Health during the years 1981-1983, which included information about 16 known and suspected animal neurocarcinogens. Acrylonitrile, ethylene oxide, and 1-H-benzotriazole had national exposure estimates of more than 50,000 workers. The health services industry had the largest number of workers potentially exposed to a single agent and the most diverse exposures in the workplace. These data provide some evidence for the pattern and presence of animal neurocarcinogens in the occupational environment and provide a basis on which to begin to develop occupational exposure tools and tojack, and then connect the other end of the cable to a MIDI-to-USB adaptor through the MIDI In jack. Plug the adaptor into your Mac using the USB port, indicated by the three-pointed trident symbol.

Create a "track," or recording space, for your Ultrabeat plug-in. First open your Logic software, and then open the Arrange window by clicking "Window" in the menu bar and selecting "Arrange" from the drop-down list. In the Arrange window, create a new Software Instrument track by clicking the "Track" menu near the top of the window and selecting "New" from the drop-down menu. When the New Tracks menu appears, select "Software Instrument" from the list of options and click "Create."
