A observation neurotoxicity its intelligence quotient children. exhibits toxicity against terrestrial aquatic animals, plants, microorganisms. presence coexisting substances modify toxicity. compounds like arsenic, calcium, magnesium, aluminum, lead, selenium been investigated for their synergetic antagonist effects.
