Impact of particulate pollution on aquatic invertebrates
Particulate matter reaches the aquatic environment through various pathways and affects the aquatic biota from both natural and man-made sources, which leads to the destruction of the aquatic ecosystem (Fig. 2). In addition to the disposal of toxic contaminants, global change, the development of cities and tourists, and the unethical use of ...

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).
