To reduce the incidence of lead poisoning fresh water and marine waterfowl, NAS recommended that nontoxic ahot be uied or that no further lead diot be Introduced into zones of shot deposition if lead shot concentrations exceed one shot per four square feet In the top two inches of sediment.

Verification of its specificity and determination of its sensitivity will then lead to an analysis of its ability to detect injury from exposure to other chemicals as well as vinyl chloride.

After reaching a red maximum, the greater the lead excess the longer it takes to degrade back to yellow.
