Science of problems, science of solutions or both? A case example of bisphenol A  -  polycarbonate
Brief introduction on October 2009, the National Institute of Environmental Health Sciences announced $30 million in funding for the Study of bisphenol (BPA).
BPA is a building material made of polycarbonate plastic and is also a widely used raw material for resins and coatings.
The focus of the study is low contribution
Dose exposure to BPA by obesity, diabetes, reproductive disorders, asthma, cardiovascular disease, and various cancers.
This study has made an important contribution to our scientific understanding of endocrine disrupting chemicals;
However, there is no dollar dedicated to the study of safer BPA alternatives.
Double phenol a reflects the limitations of our current reaction, chemistry-by-
Chemical methods for chemical evaluation and management.
Under this framework, chemicals are often considered safe, and action is unnecessary until "sound science" can adequately describe the causes and mechanisms that affect ecosystems or human health.
Therefore, the debate on the mechanism and relevance of animal research has put decision-making in trouble.
There is an implicit incentive.
For companies and scientists
Given the burden on the government to take action, the "create" uncertainty extends the regulatory debate.
This framework is inefficient and inadequate in protecting public health.
A more effective approach will focus on finding safer alternatives to chemicals to address those that may cause health problems. oas_tag. loadAd("Middle1"); BPA—
It is scientifically debatable that bpa was considered to have estrogen properties at the end of 1930, but was approved for food contact use more than 40 years ago.
Only in research shows low
The dose effects of BPA in experimental animals published at the end of 1990 do worry about a significant increase in chemicals.
Special attention has been paid to the application of potentially exposed children and developing fetus.
Research and controversy on BPA toxicity has increased significantly.
Searching for "double phenol" in the article title in the Medline database found that 1089 articles have been published since January. . .
