ISSN: 1573-2932Keywords: nitrogen removal ; waste stabilization pond ; phytoplankton ; nitrification and denitrificationSource: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringNotes: Abstract A study on the factors influencing nitrogen removal in waste water stabilization ponds was undertaken in an eight-pond series in Werribee, Australia. Nitrogen species including Kjeldahl nitrogen, total ammonia nitrogen, nitrite and nitrate were monitored monthly from March 1993 to January 1994. At the same time, pH, temperature, chlorophyll a content and dissolved oxygen were also recorded. Highest nitrogen removal occurred during the period with highest levels of chlorophyll a content and dissolved oxygen, but the rate of nitrogen removal was not related to temperature and pH. Enhanced photosynthetic activities resulting from an increased phytoplankton abundance due to prolonged detention time caused an increase in dissolved oxygen, and created an optimum condition for nitrification to occur. In this process, ammonia was oxidized to nitrite and nitrate which were subsequently reduced to elemental nitrogen. Apart from nitrification-denitrification which was the major nitrogen removal pathway in the study system, algal uptake of ammonium, nitrate and nitrite as nutrient sources also contributed to the nitrogen removal. The role of phytoplankton and zooplankton in the treatment process in waste stabilization ponds was discussed.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-3017Keywords: Polycyclic aromatic hydrocarbons (PAHs) ; DNA adducts ; mussels (Perna viridis) ; field transplantSource: Springer Online Journal Archives 1860-2000Topics: Energy, Environment Protection, Nuclear Power EngineeringNotes: Abstract Green-lipped mussels (Perna viridis) were collected from a site in Hong Kong which is relatively free from polycyclic aromatic hydrocarbon (PAH) contamination, and maintained in situ at this and three other sites with different degrees of PAH contamination. The transplanted mussels were retrieved after a 30-day field exposure. DNA adducts in the gill tissues were quantified, and tissue concentrations of benzo[a]pyrene as well as total PAHs (with potential carcinogenicity) determined for individual mussels. Results indicate that (1) tissue concentration of PAHs and adduct levels in mussels collected from a single site can be highly variable; and (2) adduct levels were related to tissue concentrations of benzo[a]pyrene as well as total PAHs of individual animals.Type of Medium: Electronic ResourceURL: -

ISSN: 1572-9575Source: Springer Online Journal Archives 1860-2000Topics: PhysicsNotes: Abstract A dynamical strongly interacting particle theory is presented. The theory explicitly exhibits the structures of particle states and provides intriguing insights into their working mechanisms. Agreement of the results with the experimental observations is excellent.Type of Medium: Electronic ResourceURL: -
