The combination of Styragel and Florisil columns allows recovery of aflatoxins at low levels. Two switching valves between the columns reduce the analysis time and exposure to solvents. Florisil is modified with oxalic acid, allowing recovery of afla
A method was devised to determine the precision of the all-glass impinger and the Andersen six-stage microbial impactor over a wide range of aerosol concentrations like those found in facilities which process solid waste. Simultaneous samples were co

Airborne total and fecal coliform concentrations averaged 2.1 X 10(3) and 9.9 X 10(2)/m3, respectively, inside an operating solid waste recovery system. Installation of dust control equipment reduced these levels by 50%. Frequency of recovery of coli

Second International Meeting on Photoacoustic Spectroscopy.
A recently acquired IBM 9600 FTIR spectrometer is being equipped for photoacoustic measurements on condensed samples. A photoacoustic cell, designed for use in the instrument, has a number of important features to enhance the signal to noise ratio an
