Deciphering the Combined Effects of Environmental Stressors on Gene Transcription: A Conceptual Approach

10.1021/acs.est.8b00749

2018-04-19

The use of classical mixture toxicity models to predict the combined effects of environmental stressors based on toxicogenomics (OMICS) data is still in its infancy. Although several studies have made attempts to implement mixture modeling in OMICS analysis t...

Engineered and Environmental Controls of Microbial Denitrification in Established Bioretention Cells

10.1021/acs.est.7b06704

2018-04-19

Bioretention cells (BRCs) are effective tools for treating urban stormwater, but nitrogen removal by these systems is highly variable. Improvements in nitrogen removal are hampered by a lack of data directly quantifying the abundance or activity of denitrifyi...

Enantioselective Toxicity in Adult Zebrafish (Danio rerio) Induced by Chiral PCB91 through Multiple Pathways

10.1021/acs.est.8b00023

2018-04-18

This study aimed to further investigate the toxic mechanism of chiral polychlorinated biphenyl (PCB) 91 in adult zebrafish (Danio rerio) exposed to racemic (rac-), (+)-, or (−)-PCB91 for 63 days. The enantioselective mortalities of adult zebrafish exposed to ...

Access to Household Water Quality Information Leads to Safer Water: A Cluster Randomized Controlled Trial in india

10.1021/acs.est.8b00035
