Welcome to the LeadNL research project. The formal title of this study is "Biomonitoring for environmental lead exposure in children from pre-1970s housing in St. John's, NL."

The sampling phase of this project closed in October 2010 so the team is no longer recruiting participants. Thank you to all the St. John's residents who have volunteered to participate in the study and to everyone who has taken an interest in this project. Please continue to follow the project as it progresses towards City-wide results reporting this spring.
