Heavy metals in eggs and chicken and the associated human health risk assessment in the mining areas of Singhbhum copper belt, India.

Metal contamination was studied in locally rearing chicken and eggs in the environs of mining areas of Singhbhum copper belt. Concentrations of metals were below Indian standards except for Cu, Ni and Zn in the case of chicken at some locations. Estimated daily intake (EDI) and target hazard quotient (THQ) suggested that the metals did not pose risk individually. However, considering the geometric mean of the metals, hazard index (HI) was above unity. Cu, Pb and Co were the key components contributing to a ...


Potential for biomonitoring metals and metalloids using fish condition and tissue analysis in an agricultural and coal mining region.

Agricultural and mining activities contribute to metal inputs in freshwater ecosystems around the world, which can in turn bioaccumulate in biota such as fish. Monitoring of metals loads in biota thus provides insight into the concentrations of bioavailable metals within the environment. Little research has been conducted on the potential of Australian freshwater fish for biomonitoring metals. Within the Fitzroy Basin of Central Queensland, a major agricultural and coal mining region, three commonly-encount...

Indian pharmaceutical patent prosecution: The changing role of Section 3(d).

India, like many developing countries, only recently began to grant pharmaceutical product patents. Indian patent law includes a provision, Section 3(d), which tries to limit grant of "secondary" pharmaceutical patents, i.e. patents on new forms of existing molecules and drugs. Previous research suggests the provision was rarely used against secondary applications in the years immediately following its enactment, and where it was, was redundant to other aspects of the patent law, raising concerns that 3(d) ...

Prediction of beauty and liking ratings for abstract and representational paintings using subjective and objective measures.

Recent research on aesthetics has challenged the adage that "beauty is in the eye of the beholder" by identifying several factors that predict ratings of beauty. However, this research has emerged in a piecemeal fashion. Most studies have examined only a few predictors of beauty, and measured either subjective or objective predictors, but not both. Whether the predictors of ratings of beauty versus liking differ has not been tested, nor has whether predictors differ for major distinctions in art, such as ab...

Chemical reactivity of natural peat towards U and Ra.

Peat is a complex material with several organic constituents that contribute to its high capacity to retain metals. In the context of uranium mining, peat can accumulate high concentrations of uranium and its decay products such as radium. Hence, interaction with peat appears to be a key factor in the understanding of the geochemical mechanisms controlling the fate of these products. This study aims to determine the sorption properties of two trace elements, U(VI) andRa, on natural organic matter from peat....
