13 Questions
What is biosorption?
The binding and concentration of heavy metals from aqueous solutions by microbial biomass.
Which countries consume about 75% of the world's most widely used metals?
United States, Germany, Russia
What specific gravity must a chemical element have to be classified as a heavy metal?
$\geq 7$ times the specific gravity of water
When do heavy metals become toxic?
When they accumulate in soft tissues
Which of the following symptoms is NOT associated with heavy metal toxicity?
Enhanced memory recall
Once dispersed in the biosphere, why are toxic metals said to be permanent in terms of environmental effects?
Because they cannot be recovered or degraded
What is the main function of biosorption in the context of heavy metals?
Binding heavy metals to microbial biomass
Why do heavy metals become toxic when they accumulate in the soft tissues?
Due to their inability to be metabolized by the body
