“…com.). Evidence has been emerging, however, that sea-chests may explain the transport of many organisms that cannot enter the ballast water tanks [57] , [58] . Their size varies with vessels as well as the diameter of the holes in the steel grille that protects them (dimensions of the order of 15–35 mm wide).…”

Marine wood-borers of the Limnoriidae cause great destruction to wooden structures exposed in the marine environment. In this study we collated occurrence data obtained from field surveys, spanning over a period of 10 years, and from an extensive literature review. We aimed to determine which wood-boring limnoriid species are established in European coastal waters; to map their past and recent distribution in Europe in order to infer species range extension or contraction; to determine species environmental requirements using climatic envelopes. Of the six species of wood-boring Limnoria previously reported occurring in Europe, only Limnoria lignorum, L. quadripunctata and L. tripunctata are established in European coastal waters. L. carinata and L. tuberculata have uncertain established status, whereas L. borealis is not established in European waters. The species with the widest distribution in Europe is Limnoria lignorum, which is also the most tolerant species to a range of salinities. L. quadripunctata and L. tripunctata appear to be stenohaline. However, the present study shows that both L. quadripunctata and L. tripunctata are more widespread in Europe than previous reports suggested. Both species have been found occurring in Europe since they were described, and their increased distribution is probably the results of a range expansion. On the other hand L. lignorum appears to be retreating poleward with ocean warming. In certain areas (e.g. southern England, and southern Portugal), limnoriids appear to be very abundant and their activity is rivalling that of teredinids. Therefore, it is important to monitor the distribution and destructive activity of these organisms in Europe.

“…However, sediments also act as a source of nickel through desorption (WHO 1991). The fate of nickel in sea water is controlled by several factors including pH, pE, ionic strength, type and concentration of organic and inorganic ligands, and the presence of solid surfaces for adsorption (Barciela-Alonso et al 2003). …”

Estuaries and coastal zones are dynamic transitional systems which provide many economic and ecological benefits to humans, but also are an ideal habitat for other organisms as well. These areas are becoming contaminated by various anthropogenic activities due to a quick economic growth and urbanization. This chapter explores the sources, chemical speciation, sediment accumulation and removal mechanisms of the harmful elements in estuarine and coastal seawaters. It also describes the effects of toxic elements on aquatic flora and fauna. Finally, the toxic element pollution of the Venice Lagoon, a transitional water body located in the northeastern part of Italy, is discussed as a case study, by presenting the procedures adopted to measure the extent of the pollution, the impacts on organisms and the restoration activities.

A new chromogenic reagent, 2-hydroxyl-5-benzeneazoformoamithiozone (HBASA) was synthesized and it can complex Co(II) and Ni(II) at pH 6.0 with high sensitivity and good selectivity. The complexations were characterized by a spectral correction technique. Complexes Co(HBASA)2 and Ni(HBASA) were formed and their stepwise stability constants (Kn) and stepwise molar absorptivities (en) were worked out. The spectral correction matrix method was applied to the simultaneous determination of Co and Ni. At the range from 0 to 12.0 mg /25-mL Co and Ni, the correction absorbances (Ab) of the mixed complexes' solutions have good linearity. The limit of detection is 0.01 mg/l Co and 0.03 mg/l Ni and the relative standard deviation (RSD) is 2.5% for Co and 5.6% for Ni. This method was applied to the analysis of wastewater. The recovery of Co was between 94.5 and 109% and that of Ni between 99.0 and 111%.
