Timing of Exposure
For many years it was believed that the risks of harmful chemicals were directly proportional to the amount of exposure. But scientists now know that the timing, duration and pattern of exposure are at least as important as the dose. The timing of exposure may be especially critical.
So while it's good to limit exposure to toxic chemicals and radiation at every stage of life, it is even more important during critical windows, including gestation, childhood and pregnancy.
