“…Penicillus capitatus and Amphiroa sp. show high cadmium contents, possibly accompanied with the physiological variations of each species [31] . However, in both calcareous algal species Cd 2+ may substitute Ca 2+ in the crystal lattice of CaCO 3 , according to their similarity in ionic radius [32] .…”

“…So, each algal species seems to have certain chemical composition. Some algae appear to uptake certain elements rather than others, according to many factors such as: ambient environment, the availability of metals to be accumulated, physiological variations among species [33] , growth stages, time of collection, temperature, ..etc [16] . Cadmium content in the muscle is ranged from 0.005 to 0.016 µg g¯1, Fig.…”

Desalination processes have environmental impacts. The brine water discharge has an impact on marine ecosystem. This is mostly due to the highly saline brine that is discharged into the sea, which may be increased by temperature, contain residual chemicals from the pretreatment process, heavy metals from corrosion or intermittently used cleaning agents. The effluent from desalination plants is a multi-component waste, with multiple effects on water, sediment and marine organisms. Therefore, it affects the quality of the resource which it depends on. In this study, selected water quality parameters in the seawater and the presence of heavy metals of concern in the sediments and algae were monitored to investigate the impacts of the discharges by seawater desalination plants using reverse osmosis on the receiving marine environment. In light of the results obtained, the analyzed water has a physicochemical quality more or less adequate, moreover, chemical analyzes in seaweed and sediments show relatively low levels of heavy metals.

“…The concentrations of both essential and toxic metals are related to the age and the size of the organism. Concentration increases according to the age of the tissues (Bohn, 1979;Warnau et al, 1995c;Lozano et al, 2003).…”

This document shows the results obtained from a study on the concentration of toxic heavy metals in the internal tissue and exoskeleton of sea urchins, collected from their natural habitat. The levels of lead and cadmium were measured by Graphite Furnace Atomic Absorption Spectrometry. The mean concentrations of lead and cadmium in the internal tissue were 304.04 and 260.54 lg/kg respectively, whereas in the shell they were 185.02 and 142.48 lg/kg. We also performed a statistical analysis of the differences in the distribution of metals between their exoskeleton and their internal content, a correlation study of the metal content in internal tissue and shell and sampling areas, and a correlation study between the metal content and sample size. Since the sea urchin Diadema antillarum presents a wide range of variation in metal content, this study suggests that this species is an excellent bioindicator of heavy metal contamination. # 2009 Wiley Periodicals, Inc.
