This investigation analyzed the Zn-bioaccumulation kinetics in the abalone Haliotis diÕersicolor supertexta and in the red alga Gracilaria tenuistipitata var. liui for assessing bioconcentration and biomagnification in an aquacultural system. Laboratory exposure experiments estimated Ž . uptake and depuration rate constants i.e., k and k , respectively of H. diÕersicolor supertexta 1 2 Ž . via ...

There are several aspects of inorganic mercury (iHg) toxicokinetics in fish that remain undeveloped despite its environmental ubiquity, bioaccumulation capacity and toxicity. Thus, this study presents new information on the uptake, distribution and accumulation of iHg following water contamination by adopting a novel set of body compartments (gills, eye wall, lens, blood, liver, brain and bile)...

Of three proposed acute toxicity models, the uptake-depuration (UD) model, the time-integrated concentration (TIC) model, and the concentration-time (CT) model are derived and verified with acute toxicity data to estimate the internal residues of waterborne metals in fish as a function of a few constants and variables. The main factors are the exposure time, the external exposure concentration,...

Successful animal rearing under laboratory conditions for commercial processes or laboratory experiments is a complex chain that includes several stressors (e.g., sampling and transport) and incurs, as a consequence, the reduction of natural animal conditions, economic losses and inconsistent and unreliable biological results. Since the invasion of the bivalve Limnoperna fortunei (Dunker, 1857)...

The relationship between agricultural heritage and climate change is embedded in urban landscape since centuries. In many European cities, ingenious water management systems have been created to cultivate land live the cities: provided food for people, animals (cows horses citizen’s transfers) depurated dirty waters. Agricultural consists of tangible intangible components historical contemporar...
