Transparency and Toxic Waste: State Decisions to Report and Import Toxic Waste

Toxic waste disposal in Escherichia coli.

About 10% of the nalidixic acid-resistant (Nal(r)) mutants in a transposition-induced library exhibited a growth factor requirement as the result of cysH, icdA, metE, or purB mutation. Resistance in all of these mutants required a functional AcrAB-TolC efflux pump, but the EmrAB-TolC pump played no obvious role. Transcription of acrAB was increased in each type of Nal(r) mutant. In the icdA and...

Psychosocial impact of toxic chemical waste dumps.

On the basis of three years' intensive observation of the community and interactions at the Love Canal in Niagara Falls, NY, the present study addresses the psychosocial problem of creating and maintaining trust between the residents of an area contaminated by toxic waste materials and the government-sponsored scientific researchers and other health professionals who worked and studied there (t...
