High-iron biosolids compost-induced changes in lead and arsenic speciation and bioaccessibility in co-contaminated soilsSally L Brown
University of Washington, Seattle, WA, USA
J Environ Qual 41:1612-22. 2012..The results of this study indicate that addition of high-Fe biosolids compost is an effective means to reduce Pb accessibility only for certain types of Fe-rich materials...
Restoration of high zinc and lead tailings with municipal biosolids and lime: a field studySally Brown
University of Washington, Seattle WA 98195, USA
J Environ Qual 38:2189-97. 2009..Limited precipitation and high electrical conductivity may be responsible for poor plant growth. Higher rainfall for the last sampling period resulted in significant growth in the LKD+BS, SBL+BS, and LKD alone treatments...
Fate of 4-nonylphenol in a biosolids amended soilSally Brown
College of Forest Resources, University of Washington, Box 352100, Seattle, WA 98195, USA
Chemosphere 75:549-54. 2009..Movement of NP below the zone of incorporation was slight (<2% of total NP present at any sampling interval) and no NP was detected in column leachates or in wheat leaves...
Greenhouse gas balance for composting operationsSally Brown
College of Forest Resources, Box 352100, Univ of Washington, Seattle, WA 98195, USA
J Environ Qual 37:1396-410. 2008..Compost end use has the potential to generate carbon credits through avoidance and sequestration of carbon; however, these are highly project specific and need to be quantified on an individual project basis...
Field test of in situ soil amendments at the Tar Creek National Priorities List Superfund siteS L Brown
Forest Resources, University of Washington, Seattle, WA 98195, USA
J Environ Qual 36:1627-34. 2007..For the tailings, BS+DAP 1% was the most effective treatment tested. These results indicate that in situ amendments offer a remedial alternative for the Tar Creek site...
Effect of amendment C:N ratio on plant richness, cover and metal content for acidic Pb and Zn mine tailings in Leadville, ColoradoSally Brown
University of Washington, Box 352100, Seattle, WA 98195, USA
Environ Pollut 149:165-72. 2007..Volunteer species and evidence of animal grazing were observed in all amended plots. Results indicate that a C:N ratio>/=20:1 increased species diversity...
An inter-laboratory study to test the ability of amendments to reduce the availability of Cd, Pb, and Zn in situSally Brown
Box 352100 University of Washington, Seattle, WA 98195, USA
Environ Pollut 138:34-45. 2005..2 and 406 mg kg(-1) Cd, Pb, and Zn). Response of soil micro-organisms was similar to plant responses. Phosphorus addition reduced the physiologically based extraction test Pb from 84% of total Pb extracted in the untreated soil to 34.1%...
Ecosystem function in alluvial tailings after biosolids and lime additionSally Brown
College of Forest Resources, University of Washington, Seattle, WA 98195, USA
J Environ Qual 34:139-48. 2005..Data suggest that ecosystem function has been restored to the amended tailings, but that these systems are not yet in equilibrium...
In situ soil treatments to reduce the phyto- and bioavailability of lead, zinc, and cadmiumSally Brown
College of Forest Resources, University of Washington, Seattle, WA 98195, USA
J Environ Qual 33:522-31. 2004..5% Fe + 1% P-TSP treatment a 50% reduction. The in vitro extraction (pH 1.5) run on field samples showed no reduction in the compost or Fe treatments. The 1% P-H3PO4 treatment was the most effective at reducing plant Pb, Zn, and Cd...
Effect of biosolids processing on lead bioavailability in an urban soilSally Brown
College of Forest Resources, Box 352100, Univ of Washington, Seattle, WA 98195, USA
J Environ Qual 32:100-8. 2003..Conventional extracts showed no changes in metal availability. These results indicate that addition of 100 g kg(-1) of high Fe and Mn biosolids composts effectively reduced Pb availability in a high Pb urban soil...
Comments on "Implications of Hormesis for Industrial Hygiene"S L Brown
R2C2, Oakland, California 94605, USA
Hum Exp Toxicol 21:397-8. 2002..Nevertheless, the proposals of Jayjock and Lewis have considerable merit, and exploratory testing could be useful...
Combined effect of arsenic trioxide and sulindac sulfide in A549 human lung cancer cells in vitroT T Jiang
Dept of Radiation Oncology, Henry Ford Health Sciences Center, Detroit, Michigan 48098, USA
J Exp Clin Cancer Res 23:259-62. 2004..Our results show that sulindac sulfide enhances cytotoxicity when combined with arsenic trioxide, and that further studies on the exact mechanisms of their interaction are needed...
