What are endocrine disruptors? How do they work on pests? Why are they a problem for humans? Have they been banned? Why or why not?
What will be an ideal response?
Endocrine disruptors are toxicants that interfere with the body's hormones. They work on pests because they mimic hormones that direct a pest organism's reproduction, growth, and development. If organisms do not grow, develop, or reproduce properly, this decreases their biotic potential and thus their potential to destroy agricultural fields or act as pests in other ways. Endocrine disruptors are problems for humans because human reproduction, growth, and development can be affected by hormone mimics. They have not been banned because scientific evidence for the problems they cause has been slow in coming. Research documenting endocrine disruptor effects is controversial because it is relatively new. Research poses economic threats to chemical manufacturers as well. For instance, Tyrone Hayes' work has met with fierce criticism from scientists associated with atrazine's manufacturer which will lose money if its use is banned or restricted.
