The new policy is to aim to reduce average blood lead levels in US children to as low a level as possible. The CDC now publishes a "reference" blood lead level which they hope can decrease in coming years. The reference value is "based on the 97.5th percentile of the BLL distribution among children 1–5 years old in the United States". [9]
Elevated blood lead levels (BLLs) in adults can damage the nervous, hematologic, reproductive, renal, cardiovascular, and gastrointestinal systems.. Current research continues to find harmful effects in adults at BLLs previously considered harmless, such as decreased renal function associated with BLLs at 5 micrograms per deciliter (μg/dL) and lower, and increased risk of hypertension and ...
Acid–base and blood gases are among the few blood constituents that exhibit substantial difference between arterial and venous values. [6] Still, pH, bicarbonate and base excess show a high level of inter-method reliability between arterial and venous tests, so arterial and venous values are roughly equivalent for these. [44]
The World Health Organization (WHO) specifically notes that there is "no known safe blood lead concentration," and that even blood lead concentrations as low as 3.5 µg/dL (micrograms per ...

In men, when blood lead levels exceed 40 μg/dL, sperm count is reduced and changes occur in volume of sperm, their motility, and their morphology. [74] A pregnant woman's elevated blood lead level can lead to miscarriage, prematurity, low birth weight, and problems with development during childhood. [75]
The Food and Drug Administration followed up with a warning against 17 ground cinnamon products found to contain high levels of lead. Short-term exposure to very low levels of lead may not result ...
Soda and juices wreak havoc on blood-sugar levels. Add some interest to seltzer by squeezing in fresh citrus, opting for flavored (but not sweetened) versions, or infusing with a sprig of fresh herbs.
