Briefly discuss the effect of occupational exposure of pregnant women to chemical solvents on their children.
What will be an ideal response?
Chemical solvents are used in the manufacture of and found in many commercial products, including paint, glues, dyes, cosmetics, and cleaning agents. The neurotoxicity of these to adults is well-established. A large-scale longitudinal study in France recruited women at the beginning of pregnancy and followed them until the child was two years old. One-fifth of the mothers reported occasional exposure on the job to these solvents, and 31 percent reported regular exposure at work. Children who were exposed prenatally were given higher scores at age 2 by their caregivers on attention deficit/hyperactivity and aggression (fighting, hitting, kicking others). Again, greater exposure was associated with more pronounced effects.
