Only minimal evidence was found of the hypothesized summer rise in blood lead level, while the predominant trend seemed to be for blood lead levels to display statistical regression to the mean. In children found to have low to intermediate blood lead levels (less than 55 microgram\/100ml) at screening, variables which were found to predict a rise in blood lead level of 10 microgram\/100ml or greater from winter to summer were under age three and\/or exposure to paint or plaster. <\/jats:p>","DOI":"10.2105\/ajph.69.4.348","type":"journal-article","created":{"date-parts":[[2008,11,27]],"date-time":"2008-11-27T05:10:13Z","timestamp":1227762613000},"page":"348-352","source":"Crossref","is-referenced-by-count":7,"title":["Longitudinal changes in blood lead level in children and their relationship to season, age, and exposure to paint or plaster."],"prefix":"10.2105","volume":"69","author":[{"given":"J","family":"McCusker","sequence":"first","affiliation":[]}],"member":"844","reference":[{"key":"p_1","doi-asserted-by":"crossref","first-page":"252","DOI":"10.1093\/clinchem\/23.2.252","volume":"23","author":"Chisolm JJ","year":"1977","journal-title":"Clin Chem"},{"key":"p_2","unstructured":"Increased Lead Absorption and Lead Poisoning in Young Children.
