Atrazine found to cause chromosonal breaks

Article Abstract:

Results of a study led by A. Lane Rayburn of the University of Illinois presented scientific evidence presenting the linkage between the use of the pesticide atrazine with birth defects and the development of cancer. In their study, hamsters exposed for 48 hours to herbicides containing a minimum of 3ppb atrazine showed chromosomal breaks, a type of aberration that leads to cancer in humans. Although the results are not conclusive for humans, they serve as a warning on the possible side-effects of atrazine.

Recycling not profitable

Article Abstract:

The recycling operations of materials recovry facilities (MRFs) were surveyed. A comparison of the average cost of processing recyclables to their average market value indicate that drop-off fees are still being charged by MRFs to meet costs. However, the recycling industry could still become more efficient as evidenced by the wide discrepancies in procssing costs. Improvements in product marketing and technology are needed for this end.

New method measures exposure to volatile organics

Article Abstract:

A new analytical method has been developed to measure human exposure to airborne volatile organic compounds using exhaled breath. The single-breath canister (SBC) method is a noninvasive exposure measure that integrates the use of a new breath collection device and mass spectrometric detection. SBC was developed by Joachim Pleil of the EPA's National Exposure Research Laboratory.
