Question 1: The first warning in the scientific literature was that synthetic chemicals could have the inadvertent effect of disrupting hormones.
ReplyDeleteQuestion 2: The paper by the two Syracuse University zoologists, Verlus Frank Lindeman and his graduate described how doses of DDT prevented young roosters from developing into normal males and even suggested that the pesticide was acting as a hormone.
Question 3: As young cockerels mature, tall red combs blossom on their heads and luxurious cherry-colored skin folds called wattles burgeon at their necks-hallmarks of rooster masculinity.
Question 4: Although studies provided alarming evidence of the power of a synthetic to derail sexual development, but the warning went unheeded. Such findings simply did not fit into prevailing views about pesticide hazards, which had been shaped by the previous generation of poisons.
ReplyDeleteQuestion 5: DDT was a safe product under the measure that if it did not cause death or obvious disease to those exposes to high concentrations, such as farmers that are exposed to pesticides containing DDT.
Question 7: Exposure to a hormone-disrupting chemical before birth does not produce just a single clear-cut effect, and in this way, too, the results defy the prevailing notions of chemically induced disease.
8) Exposure to a hormone-disrupting chemical before birth does not produce just a single clear-cut effect .
ReplyDeleteLeading researchers investigating hormone-disrupting chemicals frequently find it impossible to get funding to pursue their work.

Delete8) Despite alarming signs, such as the report of dropping male sperm count, the lion's share share of research money for investigating the effects of environmental contamination of human health still goes into cancer studies.

ReplyDelete11)Defending ourselves from this hazard requires action on several fronts aimed at eliminating new sources of hormone disruption and minimizing exposure to harmonically active contaminants already abroad in the environment.
