Blood lead levels in some pre-schoolchildren living near a lead works and particularly in some children with fathers employed at the lead works showed evidence of increased exposure. Forty-seven of them took part three years later in a follow-up study of their developmental and behavioural functions. The children were aged between 4 and 5 1/2 years and were closely matched for age, sex, social ...

Long-term airborne lead exposure, even below official occupational limits, has been found to cause lead poisoning at higher frequencies than expected, which suggests that China's existing occupational exposure limits should be reexamined. A retrospective cohort study was conducted on 1832 smelting workers from 1988 to 2008 in China. These were individuals who entered the plant and came into con...

To assess the risk of lead poisoning among preschool and school-aged children in Bangladesh, 345 children were screened for blood lead levels (BLLs) from one rural and two urban areas in Bangladesh from September 2007 through January 2008. An urban industrial area at Tongi was identified as a disaster area, where 99% (104/105) of those tested had BLLs >or= 10 microg/dL. Industrial emissions and...

Childhood lead poisoning in the United States remains a persistent, prevalent environmental public health problem, especially for children living in central-city neighborhoods. These neighborhoods typically are racially segregated, are in proximity to current and/or legacy lead emission sources, consist of older housing, and contain disproportionately African American or black children of low-i...

Geophagia (the pica of pottery, clay, earth, or dirt) is practiced before and during pregnancy in several countries, including Mexico, Turkey, Australia, and some African countries, and has been linked with cultural fertility beliefs and the satisfaction of cravings. Unfortunately, consumption of contaminated pottery can represent a source of lead exposure. Concerns regarding ingested pottery a...

Rhode Island mandates that all children under the age of six be screened for lead annually, and that all lead test results be reported to the RI Department of Health. Following the recommendations of the Centers for Disease Control and Prevention (CDC) , the Rhode Island Childhood Lead Poisoning Prevention Program (RI CLPPP) considers children under the age of six with a venous blood lead level...

Autism is a developmental disorder that impairs both nonverbal and verbal communication and reciprocal social interactions and is seen in association with an abnormally restricted range of interests. Although symptoms typically develop without clear etiological cause, some cases are associated with disorders or conditions that negatively impact brain development. Lead is a neurotoxin to which t...

OBJECTIVE Blood lead (B-Pb), one of the most used toxicological biomarker all kind, has serious limitations. Thus, the objective is to evaluate whether plasma lead (P-Pb) is more adequate. METHODS A long-term follow-up study of five cases of lead poisoning. P-Pb was analysed by inductively coupled plasma mass spectrometry. Kinetics after end of exposure was modelled. RESULTS P-Pb at severe ...

Lead (Pb) has been known to be a cause of human poisoning since ancient times, but despite this, it was a widely used metal in the European colonial period. In this study, the relationship between Pb exposure and the demographic variables ancestry and age was explored by comparing the bone Pb levels of individuals that were of either African or European ancestry, excavated from a British Royal ...

Poisoning from lead shot in waterbirds has been well documented globally and, in some countries, legislation exists to combat lead toxicosis at wetlands and/or in waterbirds. However, poisoning of terrestrial species such as raptors and upland game birds, while of potential conservation concern, remains largely to be addressed. For several species, shot are not the only ammunition source of lea...
