Not only are elevated concentrations toxic to wildlife and even to people, but also
even moderate concentrations can, if allowed to persist, fuel the explosive growth of algae.
Human infants as young as 4 months of age prefer
moderate concentrations of salt water to plain water and by 2 years of age, their preferences for salty foods are even greater than they are for adults (18,20).
Medium chain fatty acids are 8 to 12 carbons, moderately rare, but found
in moderate concentrations in some tropical nuts and oils.
«Exposing 2 to 4 dpf fish to
moderate concentrations of water - soluble proconvulsants, such as pentylenetetrazol (PTz), is sufficient to dramatically increase locomotion that can very easily be measured using the DanioVision system», according to Richard Baines (University of Manchester, UK).
Bacteria exposed to
a moderate concentration of salt survive subsequent exposure to a higher concentration better than if there is no warning event.
This is one of the minerals present in
a moderate concentration within the seeds.
