The negative effects could occur in the developing child prenatal (before birth), perinatal (just before, during, and after birth), and postnatal (after birth) all until puberty. Curious Chloride’s scanner highlights all substances linked to developmental toxicity and is continuously updated to include new findings on the subject.
Prenatal developmental toxicants are the most common ones in this category. They are the results from toxicants experienced by the mother. This can start as soon as just after fertilization, and the toxicants can be passed through from the mother to the developing embryo or fetus. These developmental toxicants, occurring before birth, are caused by substances known as teratogens. During the development of the major organs in week 14-60, the fetus is at extra risk of exposure to teratogens. But contact with toxicants just after birth, early postnatal, could also affect normal development. The possible deficits caused by toxicants become apparent as the child grows.
