Abstract

Xinfengjiang Reservoir (XFJR) is the largest drinking water source in the southern China, and plays a vital role in supporting the development of China's Pearl River delta. The levels, source Identification, potential ecological risks and health risk of eight metal elements including Zn, Pb, Ni, Mn, Cu, Cr, Cd and As in the sediments of the XFJR and Heyuan section of East River (HYER) were investigated. Sixteen sediment samples were collected from June to July 2016 in XFJR and HYER, and the concentrations of heavy metals (Zn, Pb, Ni, Mn, Cu, Cr, Cd) and As were analyzed simultaneously. Results showed that the contents of Zn, Pb, Ni, Mn, Cu, Cr, Cd and As in surface sediment of XFJR were 76.27, 36.63, 12.23, 293.61, 14.88, 60.38, 0.76 and 18.68 mg / kg , respectively, and were 76.47, 30.95, 24.47, 361.95, 23.80, 91.81, 0.68 and 7.31 mg / kg, respectively, for HYER. The pollution’s levels of the heavy metal and As was in the order of Cd > Zn > Cr > Mn > As > Cu > Ni > Pb. The spatial distribution pattern of heavy metal and As in the surface sediments of the studied area featured high concentrations in the northeastern region and low concentrations in the XFJR, with a gradual decrease along the river flow from north to south. The results of principal component analysis demonstrated that agricultural activities, industrial pollution and water vehicles were the main sources of heavy metals pollution. The potential ecological risk index of the region was 22.02, and the potential ecological risk of heavy metal and As were in the ordered of Ni > Cu > Pb > Cr > Zn > Mn > Cd >As, indicating slight ecological risk. In addition, the non-carcinogenic risk and carcinogenic risk of heavy metal and As in the surface sediment for adult and children were within acceptable level.

Abstract

Abiotic stress like drought and heavy metal imparts a negative impact on exposed plants’ growth and development, commences over production of reactive oxygen species (ROS) inside plant cells resulting in oxidative stress at the cellular level. Aftermath, plants activate multiple defense mechanisms, within which the superoxide dismutase (SOD) family act at the frontline as first line of defense to neutralize ROS. From the literature, it is evident that fewer studies have been carried out in conjunction with molecular evolution and expression profile of the SOD genome amidst dicot and the monocot at subcellular level against drought stress and cadmium (Cd) metal exposure. In the present study, SOD isogenes are identified in prepensely elected two dicot plants i.e. Arabidopsis thaliana (9 genes), Solanum lycopersicum (8 genes) and two monocot plants namely Triticum aestivum (11 genes), and Oryza sativa (7 genes), respectively. Based on the sequence similarities, the identified proteins are classified into three subfamilies in accordance to their phylogenetic relationships, namely Cu/ZnSOD, FeSOD, and MnSOD. High variability observed between Cu/ZnSOD with other two groups i.e. FeSOD and MnSOD which showed lesser variation within them by using secondary structure predication. Subcellular localization suggested that genes encoding FeSOD, MnSOD and Cu/ZnSOD are predominant in chloroplasts, mitochondria, and cytoplasm, respectively in studied plants. The expression profiling through microarray analysis showed varied strategies of SOD isogenes against drought stress and Cd exposure individually. From the perspective of evolution, this study would expand our knowledge for vivid understanding the role of distinctive SOD isogenes in detoxifying ROS in different plants under various abiotic stresses.

Abstract

Ecosystem is having a new physical dimension as evidenced by the increasing contribution from man-made plastics synthesized and consumed by our society. Anthroposphere, a brand new constituent, shall be added into the existing lithosphere, hydrosphere, atmosphere and biosphere as a whole for the ecosystem. This new class of anthropogenically-produced materials is xenobiotic and has its own physical form persistent and building up in the ecosystem. Its occurrence in different ecosystems will increase continuously over time. Its hazards and potentially effects in different ecosystems shall be evaluated with a new framework to advance a better understanding of its long-term impact and the mechanisms involved in the changing world. The impacts from these plastics shall be much more than its non-degradability and the potential hazards as observed and a better understanding based on pure science is required. A new opportunity is ahead of us for a collective and immediate action to assess the new dimension of the anthroposphere in the ecosystems to advance the new knowledge on this research subject.
