Agree with Tarlach, seems a good idea but if everybody did it,it would no doubt cause wide spread polution.There are enough chemicals in the sea already,especially in areas such as Poole Harbour where it becomes concentrated.
If it was okay , the manufacturers would use it.This is a none starter.Years ago AF manufacturers had to change their
formulas because some chemicals in AF were changing the sex of whelks.I am quite happy as a man!!!!!!
