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

Physiologic assessment of fetal compromise: biomarkers of toxic exposure.

Understanding the physiologic and endocrinologic basis of fetal development is a major goal of perinatal biology. During the past decade a number of technological developments have allowed more precise evaluation of the fetus in utero and diagnosis of abnormalities. Despite these methodological achievements, however, there are no specific biological markers currently available to indicate that ...

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...

Cultivating Bacteria's Taste for Toxic Waste

August 2006 | Volume 4 | Issue 8 | e264 Among the wealth of microbial organisms inhabiting marine environments, cyanobacteria (blue-green algae) are the most abundant photosynthetic cells. Prochlorococcus and Synechococcus, the two most common cyanobacteria, account for 30% of global carbon fi xation (through the photosynthetic process in which sugars are manufactured from carbon dioxide and wa...

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...
