The unique, physicochemical properties of nano materials may play a vital role in any possible toxic effects as compared to bulk materials. The size, surface area, composition, and shape are thought to be a few responsible for nanomaterial toxicity. Is this statement

The All Ages Lead Model (AALM) guidance will predict lead concentration in body tissues and organs for a hypothetical individual, based on a simulated lifetime of lead exposure. Statistical methods will be used to extrapolate to a population of similarly exposed individuals. The purpose of the model is to provide risk assessors and risk managers with a tool for rapidly evaluating the impact of possible sources of lead in a specific human setting where there is a concern for potential or real human exposure to lead.  Is this statement
