“…lividus could constitute a valuable biomonitor species of metal contamination in its environment (e.g. Sheppard & Bellamy 1974, Papadopoulou et al 1976, Augier et al 1989, Catsiki et al 1994, Warnau et al 1995a. However, present information is limited mainly to contaminant levels, while little is known about the kinetics of metal fluxes through P lividus, as is the case for echinoderms in general (Guary 1980, Miramand et al 1982, Nakamura et al 1986, Warnau et al 1 9 9 5~) .…”

Uptake and loss kinetics of Zn, Ag, Cd, '=CS, and 241Am by the echinoid Paracentrotus lividus contaminated through either water or food were determined in controlled laboratory radiotracer experiments using low contaminant concentrations. The echinoid efficiently accumulated most of the elements from water. The only exception was '"CS (concentration factor at steady state = 2.71. With respect to relative metal bioavailability, concentrations in the different body compartments of P lividus were generally ranked in the order: digestive wall > gonads 2 body wall >Aristotle's lantern > coelomlc fluid. However, for2''~rn, body wall uptake was as efficient as that of the digestive wall. The loss kinetics for Zn, Ag, and 1 3 4~s were described by a 2-component model whereas loss of Cd and '"'Am was linear during the time course of the experiment. Loss of the different elements was relatively slow, except for 134Cs, whose long-lived loss component was characterized by a biological half-life of 6 d. Loss of the different elements ingested wlth food was described by a single-component model for Cd, '34Cs, and &;'.Am and by a 2-component model for Zn and Ag. Parameters of the kinetics ~n d~c a t e that all (for Cd, I3Ts, and 'j1.4m) or most (for Zn and Ag) of the ingested amount of element is readily lost from the organism with the faeces. However, estimation of the assimilated fraction of elements ingested by the echlnoids suggests that food could contr~bute significantly to the total body burden of Ag in f? lividus.

“…These organisms were chosen for this pilot study because they might possibly be effective pollution indicators here since they are very common and live in an environment which is continually exposed to garbage dumping, untreated sewage inflow, land and river runoff, and atmospheric fallout from heavy traffic and various small-scale industries scattered in the city of Beirut . Papadopoulou et al (1976) have suggested that certain echinoderm species might be good indicators of industrial pollution . It has been shown that sea urchins can thrive in and around areas of sewage input and absorb dissolved organic matter, i .e ., amino acids released in sewage discharges (North, In: Marx, 1971, pp .…”

Trace metal concentrations were determined in six species of intertidal organisms common to the coast of Ras Beirut, Lebanon . Lead, cadmium, nickel, iron, and zinc were highest in the polychaete, Hermodice carunculata, but the eggs of the sea urchin, Arbacia lixula, had similar iron levels and the sea anemone, Actinia equina, had zinc concentrations which also approached levels in the polychaete . The highest copper occurred in the shore crab, Pachygrapsus transversus, while chromium was highest in the eggs of Arbacia lixula . Cystoseira spinosa, the only alga studied, had average copper and iron concentrations similar to those found in the same species in another study . Together with the sea urchin eggs, C. spinosa exhibited the most variable zinc levels in the present investigation . The fish, Thalassoma pavo, which is rather common along the rocky coastal areas of Lebanon, appeared to have fairly high concentrations of certain elements in relation to levels reported in species of fish from other locations .Sewage, garbage, industrial and agricultural waste materials all enter the Mediterranean from Lebanon without prior treatment, which along with increased land erosion, probably contribute substantially to the availability of metals to the biota studied . It is suggested that more work on trace elements in coastal organisms from the eastern Mediterranean basin be undertaken before any conclusive statements are made . Such work should also investigate the various physiological and biochemical factors involved in metal uptake and retention by each species .
