This meta-analysis examined the association between conduct problems and lead exposure. Nineteen studies on 8,561 children and adolescents were included. The average r across all 19 studies was .19 (p < .001), which is considered a medium effect size. Studies that assessed lead exposure using hair element analysis yielded considerably larger effect sizes than those that assessed lead exposure using blood, tooth, or bone lead levels. Excluding the 3 hair analysis studies, the average r was .15… Expand
Lead and Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms: a meta-analysis.
TLDR
The relation between lead exposure and ADHD symptoms was similar in magnitude to the relation betweenLead exposure and decreased IQ and between lead Exposure and conduct problems and between hyperactivity/impulsivity symptoms and lead exposure. Expand
Blood lead concentrations and children's behavioral and emotional problems: a cohort study.
TLDR
Blood lead concentrations, even at a mean concentration of 6.4 µg/dL, were associated with increased risk of behavioral problems in Chinese preschool children, including internalizing and pervasive developmental problems, which showed different patterns depending on age and sex. Expand
Childhood Lead Exposure and Attention-Deficit/Hyperactivity Disorder Symptoms: A Meta-Analysis
TLDR
Improved prevention programs for lead exposure and early identification and treatment of related concerns may decrease negative outcomes, as well as the occurrence of ADHD symptoms on a population level, thus improving public health. Expand
Prospective associations between childhood low-level lead exposure and adult mental health problems: the Port Pirie cohort study.
TLDR
The associations between early lead exposure and emotional/behavioural functioning in children might persist into adulthood, at least for females, and interventions that focus on improving the childhood home environment may have a long-term positive impact on adult mental health outcomes. Expand
Exposure to Lead and Other Heavy Metals: Child Development Outcomes
TLDR
The effects of exposure to lead and other metals in childhood in a variety of domains are reviewed, and implications for mental health diagnosis and special education eligibility are discussed, and intervention strategies are presented. Expand
Developmental lead exposure and adult criminal behavior: A 30-year prospective birth cohort study.
Using a variety of research designs and measures of lead absorption, numerous studies link childhood lead exposure to a range of cognitive and behavioral deficits, including low IQ, impulsivity,Expand
Tracing the long-term legacy of childhood lead exposure: a review of three decades of the port Pirie cohort study.
TLDR
The findings of the Port Pirie Cohort study suggest that the associations between early childhood lead exposure and subsequent developmental outcomes may persist, and minimising lead exposure in combination with improving other important early childhood factors such as parent-child interactions may be the best way to improve developmental outcomes.

Assessing conduct disturbance and fly ash exposure in children
Minimal research has been conducted on fly ash (a byproduct of coal combustion) and health outcomes among exposed communities, and even less has looked at its effect on children’s behavior. ThisExpand
Association of Childhood Lead Exposure With Adult Personality Traits and Lifelong Mental Health
TLDR
Higher childhood blood lead level was associated with greater psychopathology across the life course and difficult adult personality traits in this multidecade, longitudinal study of lead-exposed children. Expand
Reduced regional volumes associated with total psychopathy scores in an adult population with childhood lead exposure
TLDR
It is suggested that increased psychopathy scores in this cohort may be attributable to the neuroanatomical abnormalities observed and that childhood lead exposure may be influential to these outcomes. Expand

Low-level lead exposure and the IQ of children. A meta-analysis of modern studies.
TLDR
The hypothesis that lead impairs children's IQ at low dose is strongly supported by this quantitative review, and the effect is robust to the impact of any single study. Expand
Low-level lead exposure and children's IQ: a meta-analysis and search for a threshold.
TLDR
A highly significant association was found between lead exposure and children's IQ and the effect was robust to inclusion or exclusion of the strongest individual studies and to relaxing the age requirements of the meta-analysis. Expand
Lead exposure and child behavior.
TLDR
This study provides further evidence of lead's detrimental effect on child behavior at levels typical of present-day exposure and consideration of maternal morale in multiple linear and logistic regression procedures. Expand
The effect of lead exposure on behavior problems in preschool children.
TLDR
Ass associations between blood lead and preschool behavior are significant but small compared with the effects of social factors. Expand
Environmental lead and children's intelligence: a systematic review of the epidemiological evidence
TLDR
The degree of public health priority that should be devoted to detecting and reducing moderate increases in children's blood lead, compared with other important social detriments that impede children's development, needs careful consideration. Expand
Bone lead levels in adjudicated delinquents. A case control study.
TLDR
Elevated body lead burdens, measured by bone lead concentrations, are associated with elevated risk for adjudicated delinquency. Expand
Pre- and postnatal lead exposure and behavior problems in school-aged children.
TLDR
The association between early lead exposure and later problem behaviors was evaluated prospectively in a cohort of 8-year-old children born during a 12-month period at one hospital and suggested that social and emotional dysfunctions are correlates and may be expressions of increased lead exposure.

Blood-lead levels and children's behaviour--results from the Edinburgh Lead Study.
TLDR
There was a dose-response relationship between blood-lead and behaviour ratings, with no evidence of a threshold, and multiple regression analyses showed a significant relationship between log blood- lead and teachers' ratings on the total Rutter score and the aggressive/anti-social and hyperactive sub-scores.

Blood lead levels and specific attention effects in young children.
TLDR
A significant negative impact of blood lead levels on attention, but not impulsivity, in early elementary age children is documents, further delineating the specific aspects of attention related to blood lead concentrations. Expand
The long-term effects of exposure to low doses of lead in childhood. An 11-year follow-up report.
TLDR
Exposure to lead in childhood is associated with deficits in central nervous system functioning that persist into young adulthood, and lead levels were inversely related to self-reports of minor delinquent activity. Expand
