New study suggests link between environmental toxins and early onset puberty in girls

Although scientists have speculated over the negative effects of environmental toxins for years, new data suggest that certain environmental toxins may disrupt the normal growth and hormonal development of girls. Some of these toxins, such as the mycoestrogen zearalenone (ZEA) produced by the Fusarium fungus species, can be found naturally in the environment, have properties similar to the female reproductive hormone estrogen, and are also structurally similar to anabolic growth agents used in animal breeding.
