Distribution of Heavy Metals in the Coastal Marine Surficial Sediments in the Msasani Bay-Dar es Salaam Harbour Area
In Tanzania, a large amount of domestic and industrial wastes are daily released to the aquatic environment without prior treatment. The demographic pressure resulting from the about 2.5 million people in the Dar es Salaam region (according to the 2002 National Census) is the major driver of amounts of waste released. Heavy metals such as arsenic (As), cadmium (Cd), cobalt (Co), chromium (Cr), ...
متن کاملAssessment of Mercury Contamination in Surficial Sediments of Newark Bay
EXECUTIVE SUMMARY This study of mercury contamination in Newark Bay sediments was initiated from a broader study of mercury sources and material balance in the New York-New Jersey Harbor, conducted for the New York Academy of Sciences' Harbor Consortium by Themelis and Gregory (2001). The author of this report concluded that a more in-depth study should be conducted on a smaller area within the...
متن کاملSiliceous microfossil distribution in the surficial sediments of Lake Baikal
Examination of surficial sediments at 16 stations shows minor, but consistent differences in the numbers and kinds of siliceous microfossils deposited in different regions of Lake Baikal. There is a general north-south decreasing trend in total microfossil abundance on a weight basis. Endemic plankton diatom species are the most abundant component of assemblages at all stations. Chrysophyte cys...
متن کاملPhenyltins in surface sediments of the Visakhapatnam harbour, India.
Twenty-two surface sediment samples were collected from Visakhapatnam harbour, east coast of India, and analysed for monophenyltin (MPT), diphenyltin (DPT), triphenyltin (TPT), total bacteria, and TPT tolerant bacteria. Concentrations of MPT, DPT and TPT varied between 1-26, 3-28, and 0.31-145 ng Sn g(-1) dry wt, respectively. Phenyltin concentrations were influenced by ship related activities,...
متن کاملDiversity and bioactive potentials of culturable heterotrophic bacteria from the surficial sediments of the Arabian Sea
Marine sediments accommodate plethora of diverse microorganisms with varying ecological functions. In the present study, we isolated bacteria from surficial sediments of south east Arabian Sea (AS) and evaluated their bioactive potentials. A total of 131 isolates belonging to the phylum: γ-Proteobacteria (63%), Bacillales (34%) and Micrococcaceae (3%) were isolated. Among these, about 40% of th...
