Food Exposures to Lead
Exposures to lead have emanated from various sources, including food, throughout human history. Occupational and environmental exposures (especially pica) appear to account for much of the identified human disease, however, food-borne exposures deserve further investigation. Lead residues in food can result from: biological uptake from soils into plants consumed by food animals or man, usage of...
متن کاملFood Exposures to Polychlorinated Biphenyls
The PCB family of industrial chemicals has been used in a number of useful and beneficial ways for more than 40 years. PCBs have been used in capacitors, as transformer fluids, as heat transfer agents, in plasticizers and adhesives, and in sealants and printing inks. Needless to say, they have no place in the nation's food supply. The scientific community has been aware of the potential hazard ...
متن کاملExposures to lead require ongoing vigilance.
Editor — We concur with the concerns over the safety of lead expressed in the article by Helen Gavaghan (1). In many countries, environmental exposure to lead has been a protracted public health concern because of its known neurodevelopmental effects. Common lead sources include paints, industrial emissions, crockery fired with leadcontaining ceramic glaze, lead-soldered food cans and exhaust f...
متن کاملDifferent People, Different Outcomes: Assessing Genetic Susceptibility to Lead Exposures
lead toxicity manifests. A new study in fruit flies scrutinizes susceptibility on the genetic level and highlights genes that might help shape individual responses. “There are several problems in trying to find out variations and susceptibility to lead in human populations,” says study coauthor Robert Anholt, a professor of biological sciences at North Carolina State University. Uncontrolled ge...
متن کاملRacial differences in Urban children's environmental exposures to lead.
OBJECTIVES This study explored whether differences in environmental lead exposures explain the racial disparity in children's blood lead levels. METHODS Environmental sources of lead were identified for a random sample of 172 urban children. RESULTS Blood lead levels were significantly higher among Black children. Lead-contamination of dust was higher in Black children's homes, and the cond...
