Trace element trophic transfer in aquatic food webs. In this review I discuss the importance of the processes of trophic transfer of trace elements TTET in aquatic food chains and webs, and suggest some tools and strategies for their study.
The ET essential and nonessential are trophi-cally transferred and can accumulate up to toxic levels in organisms, populations and communities. The processes of TTET are very complex due to the many factors that affect them.
The characteristic high productivity, diversity and environmental seasonality associated with subtropical coastal ecosystems, pose additional complexity to the already difficult study of such processes. Today’s modern techniques and methods of study facilitate the understanding and evaluation of such processes. There are math-ematical models e.
These mechanisms can be measured experimentally trfoicas the laboratory ttroficas using radiotracers and heavy metal’s isotopes artificially enriched. The increasing pollution by, to-gether with the simultaneous eutrophication occurring in the Mexican coasts, emphasizes the urgency to study and assess TTET processes, as well as the derived environmental and public health risks.
Metal pollution, food chain and web, bioaccumulation, biomagnification, eutrophication. TTet en ecosistemas costeros subtropicales. A estas herramientas se suma una estrategia combinada de estudios de campo y de laboratorio. Hasta hace poco tiempo, no se consideraba que la tasa de ingesta fuera relevante en el estudio de la TTET.
Por otro lado, los valores de k e para elementos esenciales e. En este punto se tienen dos escenarios. Aunque es complicado y costoso mantener durante todo el ciclo de vida a especies longevas.
