Bisphenol A exposure is harmful to fertility and development of the embryo. How severe the repercussions of Bisphenol A exposure depend on the amount of exposure. Effects of long term exposure to Bisphenol A are difficult to recognize. Meanwhile, the effects of short term exposure to Bisphenol A are more prevalent. Due to the fact that Bisphenol A is found in many of the products that we as humans use daily, it is important to come to terms of the effects. The experiments above show the effect Bisphenol A has on marine life due to its vulnerability caused by human waste polluting its entirety. Every product that we use ends up in their environment and they are effected. The other experiments with mice and C.elegans are modified because they are not as susceptible. Susceptible or not the effects of bisphenol A were conclusive, long term exposure showed that the results were hard to find, meaning they were on the cellular level. Short term exposure had effects that were visible to the eye, meaning the sexual organs were distorted or behavior differences were noticed. This is alarming because this means that we might not even be able to detect the effect BPA exposure is having on ourselves until it is too late. Conclusion Although there have been several experiments discussed they have all resulted in one concluding factor. Bisphenol A is effecting the reproductive system in some way; infertility, developmental, viability of offspring, and abnormal offspring. This is eye opening not only because this is not just effecting the human race but it is also effecting marine life which is an imperative source of food. BPA is effecting our water, food, and some medicinal supply by affecting marine life. If our food is being affected and we, ourselves are being effected, we are getting a double dose of exposure through our man-made products and through food. The longer the exposure is the more serious the results become. BPA exposure and the increased chances a women has to pregnancy troubles or infertility issues has been linked, giving substantial evidence as to why BPA awareness must be publicized. Not only does it affect you or your food but it can affect your future. The experiments with rainbow trout had shown that exposure to high dose of BPA will show physically an abnormality but when exposed to low dose far worse effects occur. The embryo is not viable, generations of embryos have abnormalities and infertility issues, the parent itself has an increase in infertility. These conclusions were also confirmed by the experiments done on the zebrafish. These experiments were done with BPA exposure that is found in our environment, this means that this is happening to everyone. There has been a striking increase in infertility over the past years along with the increase of these products that contain BPA. Molecularly, Genetically, and physically marine life, humans, mice, and nematodes are being effected. The results of the experiments were detected and made known because of research imagine how the exposure to BPA is effecting your body. Imagine how many unknown flags have gone unseen >GET ANSWER
