Question

question 1
the effect of toxicants on fetuses and young children
o has not raised concern among environmental health professionals
o has been thoroughly evaluated for every chemical released into both indoor and outdoor environments
o is generally the same for adults
o is greater because of their developmental immaturity, rapid growth, and smaller biomass
o is less than for adults because their metabolism is higher

Explanation:

Fetuses and young children have developmental immaturity, rapid growth, and smaller biomass. These factors make them more vulnerable to toxicants. Environmental health professionals do have concerns about this (so the first option is wrong). Not every chemical's effect on them has been thoroughly evaluated (second option wrong). Their response is not the same as adults (third option wrong). Higher metabolism doesn't make the effect less; rather, their vulnerability factors make the effect greater.

Answer:

is greater because of their developmental immaturity, rapid growth, and smaller biomass
