Guidance values of target lives for various facilities based on a survey of opinions are shown.
One aim of the study was to establish biological monitoring guidance values (BMGVs) for different branches.
Guidance values for the equilibrium moisture content of reinforced timber members in different types of use are given.
If you have tested your soil for lead or other metals, comparing results to both soil background concentrations and health-based guidance values can be helpful.
If you have tested your soil, comparing results to both soil background concentrations and health-based guidance values can be helpful.
A Cornell pilot study of 44 gardens in New York City shows that less than 10percentt of soil samples tested had more lead than state guidance values.
Comparison of the calculated dietary exposures with the generally accepted health-based guidance values revealed that most compounds do not pose any risk.
"The risk areas reflect the higher ground moisture content and reduced flash flood guidance values in the central to southern Appalachians and adjacent valley areas of eastern Kentucky and Tennessee," it wrote.
In many cases where results exceeded the guidance values, only one or two of 11 samples taken from each garden were excessive, and they were often in samples collected from the ground rather than from beds used to grow food.
In 12 of the 44 gardens, levels of contaminants were below guidance values in all soil samples tested, reports Murray McBride, director of the Cornell Waste Management Institute, professor of crop and soil sciences, and principal investigator.
If you have tested your soil, Understanding Results can help you figure out how your levels of lead or other chemicals compare to background levels and health-based guidance values.
