environmental teratogens

Environmental teratogens are substances or factors in the environment that can cause harm to a developing fetus, potentially leading to birth defects or developmental issues. These include certain medications, chemicals, radiation, infections, and pollutants like lead or alcohol. When a pregnant person is exposed to these teratogens during critical times of pregnancy, they can interfere with normal development, affecting organs, limbs, or brain formation. The impact depends on the type of teratogen, timing, and exposure level. Awareness and avoiding harmful substances during pregnancy can help reduce the risk of birth defects caused by environmental teratogens.
