Effects of low levels of cadmium and lead on cognitive functioning in children.
TLDR
Hair cadmium and lead content were related to intelligence tests, motor impairment assessments, and school achievement scores from 149 children aged 5 to 16 yr enrolled in rural Maryland public school systems and Hierarchical regression analyses suggest that Cadmium has a significantly stronger effect on verbal I.Q. than does lead.Abstract:
Hair cadmium and lead content were related to intelligence tests, motor impairment assessments, and school achievement scores from 149 children aged 5 to 16 yr enrolled in rural Maryland public school systems. Hair cadmium and lead were significantly correlated with both intelligence scores and school achievement scores, but not motor impairment scores. Significant relations with I.Q. were obtained after regressing out demographic factors and were observed, even in children within a normal I.Q. range. Evidence of different effects of cadmium and lead on cognitive development was obtained. Hierarchical regression analyses suggest that cadmium has a significantly stronger effect on verbal I.Q. than does lead and that lead has a stronger effect on performance I.Q. than does cadmium.read more

TL;DR: The development of the cerebral hemispheres was assessed by using measures of electroencephalographic coherence and phase in 577 children ranging in age from 2 months to early adulthood to note continuous growth processes that were described best by an exponential growth function and discrete growth spurts that appeared in specific anatomical locations at specific postnatal periods.

TL;DR: This review summarizes the level of epidemiologic evidence for relationships between prenatal and/or early life exposure to environmental chemical contaminants and fetal, child, and adult health and points to three main needs.

Cadmium and Its Neurotoxic Effects
TL;DR: The available finding indicates the neurotoxic effects of Cd that was associated with both biochemical changes of the cell and functional changes of central nervous system, suggesting that neurot toxic effects may play a role in the systemic toxic effects of the exposure to Cd, particularly the long-term exposure.

An Evaluation of Ten Pairwise Multiple Comparison Procedures by Monte Carlo Methods
S. G. Carmer,M. R. Swanson +1 more
TL;DR: In this article, computer simulation techniques were used to study the Type I and Type III error rates and the correct decision rates for ten pairwise multiple comparison procedures, and the results indicated that Scheffe's test, Tukey's test and the Student-Newman-Keuls test are less appropriate than either the least significant difference with the restriction that the analysis of variance F value be significant at α =.05, two Bayesian modifications of the smallest significant difference, or Duncan's multiple range test.

Lead in Albacore: guide to lead pollution in Americans.
TL;DR: The magnitude of the pollution effect of lead contamination in canned tuna helps explain how skeletal concentrations of lead in typical Americans became elevated 500-fold above the natural concentrations measured in bones of Peruvians who lived in an unpolluted environment 1800 years ago.

TL;DR: The present study was undertaken to see whether any children being referred to The Hospital for Sick Children, Great Ormond Street, for the investigation of mental retardation had lead poisoning, and to draw attention to the fact that the actual level at which poisoning occurs is variable.

House and Hand Dust As a Potential Source of Childhood Lead Exposure
TL;DR: Dust containing lead was found on the hands of inner-city children and interior household surfaces in substantially larger amounts than in similar suburban settings, suggesting that children may ingest this lead through typically frequent mouthing activity.
