Little information is available regarding the suitability of analytical methods to evaluate claims regarding the presence of engineered nanomaterials (NMs) in consumer products, their potential toxic effects to humans, or their life cycle after product use. This study was designed to assess the potential interactions across the life cycle of eight commercially available dietary supplement drinks from a single vendor, all purported to contain metal NMs.

As Lok Sabha elections 2014 in India ends with vote-counting on 16 May 2014, this paper published in Nature warns that with two of the three main parties making scant mention of science in their manifestos, Indian science will not get the boost it needs to become internationally competitive. Says that whichever party wins, the government must do more than pay lip service to science.

Photodegradation is one of the advanced oxidation processes rather than other treatments and it is most effective for the removal of organic pollutants. ZnO is an excellent photocatalytic oxidation material. In the present study nanosized ZnO has prepared by coprecipitation technique under different experimental conditions and employed in the removal of dyes colour.

Based on previously published hydroponic plant, planktonic bacterial, and soil microbial community research, manufactured nanomaterial (MNM) environmental buildup could profoundly alter soil-based food crop quality and yield. However, thus far, no single study has at once examined the full implications, as no studies have involved growing plants to full maturity in MNM-contaminated field soil. We have done so for soybean, a major global commodity crop, using farm soil amended with two high-production metal oxide MNMs (nano-CeO2 and -ZnO).

The increasing industrial application of metal oxide Engineered Nano-Particles (ENPs) is likely to increase their environmental release to soils. While the potential of metal oxide ENPs as environmental toxicants has been shown, lack of suitable control treatments have compromised the power of many previous assessments. We evaluated the ecotoxicity of ENP (nano) forms of Zn and Cu oxides in two different soils by measuring their ability to inhibit bacterial growth.
