Stabilization of biosolids with nanoscale zero-valent iron (nZVI)

Journal of Nanoparticle Research, 2007
Biosolids are the treated organic residuals, also known as sludge, that are generated from domestic wastewater treatment plants. According to the USEPA, over 7 millions tons (dry weight) of biosolids are generated every year in the US by more than the 16,000 wastewater treatment plants and a large portion of these biosolids is disposed on land ...

Study on Cytotoxicity of Nanoscale Zero Valent Iron Particles

Materials Science Forum, 2011
Although small nZNI nanoparticles are useful in various applications, the biosafety of this material needs to be evaluated. In this study, Escherichia coli cells were exposed to 0, 112, 560, 1120 mg/L of nano-Fe0particles, respectively. Experiments were carried out to examine the activities of lactate dehydrogenase (LDH), cellular superoxide dismutase (
