This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Florida's estuaries support a wide range of species yet little is known about tracemetal cycling among members of this important ecosystem. To examine the flow of trace metals through the Tampa Bay estuary, four fish species representing different trophic levels were analyzed for copper (Cu), zinc (Zn) and stable isotopes of carbon (C) and nitrogen (N). Species selected were the striped mullet (Mugil cephalus), tidewater mojarra (Eucinostomus harengulus), bay anchovy (Anchoa mitchilli), and sand seatrout (Cynoscion arenarius). Juvenile fish were collected from the Alafia, Hillsborough, Palm, and Little Manatee Rivers. Adults were collected from Tampa Bay. Combinations of trace metal and stable isotope analyses were used to evaluate geographic variability in trace metal concentrations among locations in Tampa Bay and to shed light on trophic pathways that lead to trace metal accumulation. In juvenile mullet, significant trends were found between Zn concentrations, stable isotope ratios, and standard length. Animals of the smallest size classes carry greater concentrations of zinc in their tissues and have distinct stable isotope ratios that reflect their recent life history as offshore planktivorous larvae. Interestingly, the ratio of Zn:Cu concentrations was highly conserved. While species-specific differences were observed, relatively small Zn:Cu variations suggest a possible bioregulatory mechanism that maintains an optimal Zn:Cu ratio even in the presence of elevated absolute metal concentrations. Stable isotope ratios proved to be an effective tracer of ontogenetic changes in fish diet and habitat. Carbon and nitrogen stable isotope analyses revealed that trophic relations between species are established very early in an organism's life history. The bay anchovy, a major prey item of the sand seatrout, has delta15N values very similar to this predator. Although trophic linkages between trace metals and stable isotopes proved difficult to interpret, the relation between zinc concentrations and delta13C values suggested that trace metal concentrations are highest in animals that utilize food webs based on terrestrial carbon.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, rapid scientific advances have been shattering classical concepts of oceanic trace metals concentrations. Most of the data gathered before the mid-1970s have had to be discarded. Possible associations of organic and inorganic ligands with the metals were throwing views of metal speciation into great uncertainty. Biological effects of metals need to be re-examined after recent revelations of unsuspected metal contaminations in methodology. The investigations appear chaotic, yet exciting. It implies that a new order is going to replace the past. Now, an opportunity opens its door to a brave new world for the young generation of scientists to put metal chemistries in the oceans into perspectiveo This N. AoToO. International Conference on "Trace Metals in Sea Water" hoped to catalyze this exciting process of unifying various aspects of trace metals in sea water in future years o The Conference, in the form of an Advanced Research Institute supported by the Scientific Affairs Division of NoAoT. O. supple mented by further assistance of the UoS. Office of Naval "Research, was held at the "Ettore Majorana" Center for Scientific Culture in the medieval town of Erice on the island of Sicily, Italy from March 30 to April 3, 1981. It was the first organized gathering of international scientists in this specialized field. Seventy scientists with various expertise in different aspects of the subject were present: including those from NoAoT. Oo countries (Canada, France, F. R. Germany, Greece, Iceland, Italy, U. K.

Book excerpt: The present study was conducted during the period from January 2010 to December 2010 in south sector of Main out full drain, Nassiriya. Three stations were fixed to achieve the study. The concentration of eight trace metals (cadmium, cobalt, copper, iron, manganese, nickel, lead and zinc) were measured in dissolved and particulate phases of water, exchangeable and residual phases of the sediment and tissues (gills, liver, gut, muscle, ovary and kidney) of two important commercial species of fish Cyprinus carpio L. and Barbus luteus L. In addition, the concentrations of these metals in blood samples of some citizens of study area were measured.The TMs concentration in the particles phase are much more than the dissolved phase.The TMs concentration in the residual phase are much more than the exchangeable phase expect Cd, Pb metals can be attributed to anthropogenic sources.Although fish are particularly good indicators of TMs pollution, it is clear that the different species have different affinities for certain metals, also fish tissues have different affinities for certain trace metals even in the same species.
