Comprehensive Environmental Risk Research Program

We are using millions of chemical substances to make our daily lives convenient and comfortable but part of these could be released into the environment to cause adverse effects on human health and/or eco-system.
In contrast, there are still huge unknown issues about the various effects on various organisms and how much of what chemicals remain in the environment, which is like what we have known is only "“tip of the iceberg”".
