The plastic products that conveniently discards, film, already became system of air of contaminative whole world, water, soil " the environment is hormonal " . City of our country Wuhan east lake part fish appears " male fish is female change " , make a when person Jing heart meets the eye namely. And in the west, the sexual function of men appears low, become the fact that does not contend for already. This is communal and wholesome domain appears new task: Environmental estrogen is polluted!
Litter pollutes water of all corners of the country, well to wait. After environmental estrogen material enters human body, with human body normal excretive hormone competes, the hormone in combining a cell suffers body, cause human body hormone superfluous, internal system is disorder, affect the regular job of human body sex hormone, appear all sorts of dysfunction. The female appears more different of the film inside the uterus, uterine flesh tumour, the disease such as ovarian cancer, breast cancer. The amount of cancer of much occurrence spermary, prostate cancer, spermatozoon and quality issue the male demote symptom. Epidemiology investigation shows afore-mentioned diseases come nearly 10 years incidence of a disease rises apparently, among them the most apparent is overall spermatozoon amount reduces the male. According to 1992 the report of Danish researcher, be in mere inside 50 years, the average spermatozoon number of human male decreased 45% . They centered the discovery after was being analysed about the findings statistic of spermatozoon amount later 1938, the average spermatozoon number of the male on the world is 1 milliliter before in 50 time 100 million above are contained in seminal fluid, and reduce 6 ten million the following later to 90 time. That is to say, decreased almost half! The amount that is spermatozoon not only decreases quickly, and the quality of spermatozoon also is reduced apparently, expression produces abnormal change in the configuration of spermatozoon, vigor is apparently abate also. Additional, as a result of fetal suffer hormone of the mother's body the impact is bigger, reason appears more easily all sorts of deformation, have next urethral cracking commonly, spermary not development and androgynous proof (epicene) etc.
Environmental estrogen material is consist in environment in, have the chemical matter of property of the hormone inside similar organism, the internal system of main and disturbed human body. Have have the organic chloric pesticide such as DDT, PCB representatively (benzene of much more chloric couplet) apperception learns combustion of material, rubbish to arise 2 evil flower wait for the noxiousness gas, DES that synthesizes hormone to use as the female (already Xi female phenol) medicines and chemical reagents waiting for cure. Additional, the Freon that old-style freezer produces; All sorts of plastic products, especially plastic food appliance can release benzene of many couplet phenol A, adjacent ester of 2 formic acid, polyethylene, PCB gets together chloric couplet benzene; The benzene ketone in still having cosmetic, acid resistant benzene of agent BHA, hydroxide; And all sorts of pigment, antiseptic. These environmental estrogen material in us the nowhere in daily life is absent, healthy to us influence nots allow to ignore.
