Re: How do Bisphenols affect marine life?

Dear Josephine
Here is a brief Information about Bisphenol or Bisphenol A that is present in plastics;

Bisphenol A, commonly abbreviated as BPA, is an organic compound with two phenol functional 
groups. It is a difunctional building block of several important plastics and plastic additives. With 
an annual production of 2–3 million metric tonnes, it is an important monomer in the production 
of polycarbonate.
Suspected of being hazardous to humans since the 1930s, concerns about the use of bisphenol A 
in consumer products was regularly reported in the news media in 2008 when several 
governments issued reports questioning its safety, and some retailers removed products made 
from it off their shelves.

Its Uses;
It is generally used to as a additive to make Polycarbonate plastic, which is clear and nearly 
shatter-proof, is used to make a variety of common products including baby and water bottles, 
sports equipment, medical and dental devices, dental fillings and sealants, lenses, CDs and 
DVDs, and household electronics. Epoxy resins containing bisphenol A are used as coatings on 
the inside of almost all food and beverage cans. Bisphenol A is also a precursor to the flame 
retardant, tetrabromobisphenol A, and was formerly used as a fungicide.

Did you look at this Wikipedia Reference? http://en.wikipedia.org/wiki/Bisphenol_A

Please go through it...you will find lot of information about the toxicity of bisphenol and its 
effect on various animals

Yes, you can conduct your experiments by putting plastic of specific sizes and origin in tank to 
see their effect on aquatic animals...

But the effect of Bishpenol on aquatic animals will depend on the concentration in which it is 
present in the plastic that you will choose.  If it is too low concentration, then you may not find 
any change or subtle changes in your test animals.

I hope this has answered your question
