Resumen:
Total mercury and /ead levels have been determined :for eighteenmarine organism.> of the Coastal Lagoon at Mar Chiquita.A marked correlation was found behveen total mercury conlents inthese organisms and their corresponding trophic leve{. This confir1nedthat. there is a bio-accum·uJation of mercury throrighout rhetrophic web. Mercury contents were found to be below the internatiotuJIstandards accepted by most countries.Aniongst the ret1iewed tissues, those that are highly caicified havethe highest lead concentrations. No proof was found .of any leadbio-accumulation throughour the food chain. Ali of 1/tte analysedorganisms had levels of lead content in excess of the internationalstandards required for human co1isumption.
