Abstract:

Quantum dots that contain cadmium, selenium and zinc are not toxic to monkeys for periods of up to 90 days, but longer-term studies are needed to determine the ultimate fate of the heavy metals that accumulate in the organs.

Toxicity Testing in Animals

Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...
