Dinoflagellate cyst assemblages in recent sediments of Visakhapatnam harbour, east coast of India: influence of environmental characteristics.
The distribution and abundance of dinoflagellate cysts in recent sediments from Visakhapatnam harbour, east coast of India was investigated and compared with sediment characteristics and physico-chemical variables of the overlying water column. The cyst abundance varied from 11 to 1218 cysts g⁻¹ dry sediment. Changes in the cyst assemblages from phototrophic to heterotrophic forms were observed...
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 کاملDistribution and abundance of benthic macroorganisms in and around Visakhapatnam Harbour on the east coast of India
Benthic communities form an important component of the marine food chain. Their occurrence also provides information on the health of the ecosystem. A study was carried out to understand the distribution and abundance of macrobenthos along with sediment characteristics and physicochemical parameters in Visakhapatnam harbour, a major port along the east coast of India. In all 84 macrobenthic tax...
متن کاملMicrobiological Examination of Three Types of Common Edible Marine Fishes from Visakhapatnam Fishing Harbour, East Coast of India
The present study was carried out for microbiological analysis to assess the quality of raw fish sold in the Fishing harbour of Visakhapatnam, East Coast of India. The study was performed during the period of April 2012 to March 2013. Three commonly edible fishes were selected for the microbial analysis to evaluate the quality of fish samples in terms of microbial content, the samples were inoc...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
