If my cow drinks water contaminated by salt, will it go blind?
We did the research and the answer is no. Cows have a limited tolerance for salt water and will stop drinking it, even if it is the only water available to them. It was determined that the cows went blind due to another cause.
If worms eat contaminated soil, can I still use them for fish bait?
Yes, the available research indicates that chemicals do not bio-accumulate in the common earthworm.
Is it safe for my toddler to chew on a picnic table made from recycled plastic?
We responded it is probably not a good idea to have your kid chew on plastic – recycled or otherwise – that has not been approved by the Consumer Products Safety Council.
If a contaminated site has been cleaned up and is acceptable for use by humans is it also safe for burrowing dogs?
Yes, but not for the reason you might think. It is true that dogs have a smaller body mass than humans. However, from a risk assessment standpoint, a dog’s shorter life span (12–15 years on average) is the deciding factor.
Why do children eat lead-based paint?
Lead-based paint has a sweet flavor; in fact, it has been compared in flavor to certain types of candies.
Do wetlands have cattails and standing water?
Not necessarily , while it is common in some landscapes to see wetlands containing water and cattails. It is also common to have wetlands which are only saturated at the surface and contain a variety of other plants, shrubs, and tree species. Just because it does not have standing water does not mean it is not a wetland.
