Lead Poisoning in Philadelphia, 1955–1960

Quantities of lead producing health effects in humans: sources and bioavailability.

“…Blood lead values for the control children were not reported in this publication. Eight children who had been hospitalized with the suspicion of elevated body burdens of lead excreted averages of 4,7,18,19,20,40,49, and 1640 ,ug/g dry weight/day. For these children an average excretion is not very meaningful as two of them excreted lead in the control range, while one child excreted in excess of 1640 ,ug/g dry weight/day.…”

Factors Influencing Metabolism and Toxicity of Metals: A Consensus Report

“…The role of the seasonal factors, such as time spent outdoors, sun irradiation, variation in nutritional status including vitamin D levels, has been discussed (276). Characteristic seasonal distribution of fatal and nonfatal childhood lead poisoning is well documented in the American literature, with up to 90%o of all cases occurring during the months of May through October (277)(278)(279)(280). Similar seasonal patterns in the occurrence of lead poisoning were reported also in domestic animals (281).…”

Quantities of Lead Producing Health Effects in Humans: Sources and Bioavailability

“…The amount of water consumed varies according to age, season of the year, and amount of beverages consumed other than water. Leadcontaining paint has been the cause of numerous cases of lead poisoning; this relationship is well documented (18)(19)(20)(21)(22)(23). Unless the lead concentration of the water is above the PHS Drinking Water Standard, even persons consuming large amounts of water are exposed to relatively little lead from this souree.…”
