This study evaluated the persistence of heavy metals, cadmium (Cd), lead (Pb) and mercury (Hg) in surficial marine sediments and their relationship with textural characteristics. Furthermore, heavy metal distribution was studied against organic carbon concentration within the sediments. Our results suggest that Cochin estuary is highly polluted in the case of all heavy metals (Pb of 29.48± 4.37µg/g, Cd of 0.21± 0.17µg/g and Hg of 0.17± 0.15µg/g). All the studied trace elements showed negative correlation with sand particles.

Global economics, not declining sea ice, is driving ships to the Arctic Ocean. Only international regulation will protect the region, says Lawson Brigham.

The ecosystem-level impacts of the Deepwater Horizon disaster have been largely unpredictable due to the unique setting and magnitude of this spill. We used a five-year (2006–2010) data set within the oil-affected region to explore acute consequences for early-stage survival of fish species  inhabiting seagrass nursery habitat. Although many of these species
