| Currently, federal or state guideline in United States does not specify any obligation on the producers of nanoparticles to carry out toxicological studies before it is introduced into the environment. These nanoparticles find there way in the environment through products for human consumption or accidental release. Thus, while nanoparticles have found its way into the environment, little knowledge exists on the influence of nanoparticles on environment. In the current study we have investigated the influence of free nanoparticles on soil health and microbial community in the soil. Copper, Gold, Paladium and Silica based nanoparticles were mixed with the soil and incubated in microcosms for 30 days. Evaluation of ecotoxicity of the nanoparticles were carried out through microbial viability count, Fatty Acid Methyl Ester analysis, Biolog Eco plates, phyto-toxicity and physico-chemical analysis of soil. Results show that the studied nanoparticles does influence the soil health and the type of influence varries with the nanoparticle under study. |
