6. Are there certain concentrations that cause harm? What are they?
Concentrations for adult rats.
LD50 of BPA was 35.26 mg/kg according to NCBI.
“Injection of lethal dose of BPA (40 mg/kg body weight) produced acute toxicity manifesting as immediate respiratory arrest and hypotension after the injection of BPA followed by bradycardia. The animals died within 7.3 +/- 0.7 min.”, https://www.ncbi.nlm.nih.gov/pubmed/22734254.
Honestly was too much work to find any good result from exposure to humans, as I could only the amount of exposure to affect sexual health in chinese workers. Here is a link to take a look, honestly not worth it to put it all down here. So I just copied the table and put it after the citations, this is the original …show more content…
in question three I address the half lifes in nature.
8. What are some alternatives to Bpa?
Bpa-free products:
Bpa free products are a great alternative, except that Bpa-free products are not as strong as their Bpa coated counterparts. There are also new studies saying that some Bpa-free plastics use chemicals as dangerous as Bpa coated products, but everyone can reassure you that glass and stainless steel are not on the danger charts.
Bisguaiacol-F (BGF):
BGF is developed using lignin, a waste product from paper making that could be a safer alternative to Bpa, currently being developed by Reno, and Richard Wool, Ph.D., at the university of Delaware. The duo have developed process that converts lignin into a compound called Bisaguaiacol-F, which happens to have the same molecular shape as Bpa. The duo are confident that BGF is incapable of interfering with hormones, but retains the desirable properties from Bpa, like the strength, and efficiency to make, as there has been reported 70 million tons of lignin from papermaking, and other wood-pulping processes.
