Toxic chemicals can affect children either (1) directly, by damaging brain cells, or (2) indirectly, either (a) through epigenetic changes (many of which occur during pregnancy) or (b) by mimicking naturally occurring hormones, and thus tipping a delicate balance.
Children are particularly vulnerable to toxic exposure for two reasons: (1) their brains are growing and changing rapidly, particularly the younger they are, and so there are many more “processes” going on daily that can be potentially altered and (2) because their bodies are small, thus the same amount of toxic chemicals equates to higher percentage of body weight, the smaller the child.
The younger the child, the greater the risk of toxic exposure, with pregnancy being a particularly critical time.
