Environmental lead exposure in St. John's, Newfoundland
Residential soil and house dust samples were collected in St. John's to quantify the extent of lead contamination. Fifty-one percent of soil samples collected exceeded the CCME guideline of 140 ppm for lead (n=T231). Only 12% of house dust samples were above the US EPA standards (n=95). Histori...
