ability of each metal in the environmental medium and the route of uptake, storage and excretion mechanisms. Metal speciation influences metal bioavailability and toxicity to biota, its transportation and mobilization, and its interaction with the environment. The actual metal speciation is influencCarbon-Monoxide 发表于 2025-3-28 19:05:07

Laurent Audigéincreases 1.5-fold by decreasing soil pH with one unit. Crops differ in Cd uptake and hard wheat and potatoes have a considerable impact on the dietary Cd intake. Contrasting views exist on the food chain risk of Cd as both soil Cd and food Cd bioavailability may have been larger in the Japanese casChampion 发表于 2025-3-29 03:05:18
Heinz Bereiterplications are shown. Results are discussed in view of the uncertainty and applicability of the critical load concept for heavy metals in future agreements on the reduction of metal emissions. It is concluded that for policy applications, dynamic models are also needed to estimate the times involvedattenuate 发表于 2025-3-29 09:09:42

Peter Engelhardthis physical dimension, material flow models may be combined with economic models. This allows the study of policy packages in which physical and economic aspects are considered simultaneously. This results in analyses that are economically consistent and physically feasible.极大痛苦 发表于 2025-3-29 17:04:36

Karl Grobtotoxic, so the concern about these metals is mainly directed at effects on crop yields and soil productivity. Together with cadmium, zinc may be considered as a mobile and bioavailable metal which may accumulate in crops and human diets (Kiekens, 1995). Food plants which tolerate relatively high coHorizon 发表于 2025-3-30 07:52:07
