Radioanalytical Method for the Measurement of Activity of 210Po and 210Pb in Soil and Sediment| Chapter 4 | Recent Trends in Chemical and Material Sciences Vol.6

The seasonal change of 210Po and 210Pb in the soil and sediment of the Hemavathi River Environment is discussed in this paper. The concentration of 210Po and 210Pb in the samples was evaluated using a conventional radiochemical analytical method during the pre-monsoon and monsoon seasons. In the monsoon and pre-monsoon seasons, the mean activity concentration…

Study on Source and Distribution of Polycyclic Aromatic Hydrocarbons (PAHs) in Water and Coastal Sediment from the Ngoua River in Douala, Cameroon

The goal of this monitoring project is to identify the source and distribution of Polycyclic Aromatic Hydrocarbons in Ngoua River water and coastal sediments. The identification and quantification of 15EPA-PAHs in water and sediment samples collected from the Ngoua River in Douala, Cameroon are reported in this research. The PAH pollution in the Ngoua River…

An Assessmental Study on the Determination of Heavy Metals in Sediment of Fish Farms in Bangladesh

Despite scarce scientific work on revier sediemtn and fish in Bangladesh, heavy metal pollution of aquatic ecosystems is often most evident in sediments, but unfortunately no work has yet been published particularly on heavy metal contamination of fresh water fish farm sediments. In order to assess the environmental contamination of the selected fish farms in…

Toxicology of Nickel

The study was carried out in Eagle Island River, located in Mgbuosimini community, Port Harcourt, Nigeria. In this study, the concentration of Nickel (Ni) in sediments and periwinkles (Tympanotonus fuscatus) were determined from 25 sample stations in Eagle Island River. The portion of the periwinkle that was assayed was the edible part. The assay was…

Three Dimensional Velocity Distribution Modelling of Nun River in Nigeria

In this study, hydrodynamics and sediment concentration equations of partial differential in 3-dimensions were solved using finite difference methods, the Crank Nicolson procedure to predict both sediment concentration and velocity profile of Nun River. The computer software (EKU2.8) which is a modification of the Navier Stoke’s equations was employed for discretization of Nun River stretch…

Speciation of Some Heavy Metals in Sediments of the Pennington River, Bayelsa State, Nigeria

Speciation helps in the identifications and quantification of the defined geochemical fractions, forms or phases  in  which  an  element  exists  in  the  environment.  Speciation  in  sediment  compartment  is  a significant step to understand the potential environmental risk, distribution, mobility and bioavailability of pollutants. The total heavy metal concentrations of some environmentally toxic metals in sediments…
