M8.5: Ideal Chemical Policy
An ideal chemical policy would ensure all chemicals meet a safe level exposure test. It would require that all chemicals degrade safely within a certain period of time to reduce prolonged risk of exposure. One thing that sticks with me since I learned about it is the persistence of chemicals in the environment. It shocks me that decades later, some of the harmful chemicals that have been banned are still detected in our bodies and in newborns as well. Just like compost is good for the environment, chemicals in the environment should be able to safely degrade too.

I really like this idea of the safe exposure levels as the chemicals degrade over time. It blows me away how stuff like PCBs were banned in the 70s yet we're still exposed. I have faith that a scientific method will be able to be discovered sooner than later considering how advanced the world is becoming.
ReplyDeleteI think this is a great idea. Even though lead has stopped being used in house paint since the 80s, there are still so many homes built long before that that probably still have traces of lead. I don't think anyone really realizes how persistent chemicals are- I sure didn't until this class. We have to enforce stronger regulation and testing before some chemicals are put back out into the environment and our bodies.
