Case study: Zinc in the environment — Science Learning Hub

Once released in the environment, zinc behaves in different ways depending on the characteristics of the environment: In water, the pH among other factors will determine if zinc is in a freely dissolved form or is attached to sediment. In acidic waters where the pH is low, zinc tends to dissolve and be in a free form, making it more available ...

swimming speed (U-Cru) was significantly reduced in zinc-exposed fish, an effect that persisted in zinc-free water. Using radioisotopic techniques to distinguish new zinc incorporation, the gills were found to possess two zinc pools: a fast turnover pool (T-1/2 = 3-4 h) and a slow turnover pool (T-1/2 = days to months).
