Children’s personal exposure to PM10 and associated metals in urban, rural and mining activity areas
21
TL;DR: A small study of children's personal exposure to PM10 and associated metals in rural and iron ore mining activity areas where PM10 concentrations can be very high found hair aluminium, cadmium and manganese concentrations were higher in the iron ore activity area, while hair mercury, copper and nickel concentrations wereHigher in the urban area.

Spatial and Temporal Dynamics in Air Pollution Exposure Assessment.
Daniela Dias,Oxana Tchepel +1 more
TL;DR: This review suggests that the spatial and temporal variability of urban air pollution levels in combination with indoor exposures and individual’s time-activity patterns are key elements of personal exposure assessment.
Pollution by metals and toxicity assessment using Caenorhabditis elegans in sediments from the Magdalena River, Colombia.
TL;DR: Cadmium and lead were the metals which were primarily associated with sediment toxicity, and the sampling sites with the highest increased expression of stress response genes were Barrancabermeja and Girardot.

Lung bioaccessibility of contaminants in particulate matter of geological origin.
TL;DR: The contaminants in PM of geological origin and their relevance for human exposure are discussed, lung bioaccessibility assessment methods and their use are evaluated and a crucial need for test method standardization and comparison with relevant animal data is noted.

Source apportionment and source-specific health risk assessment of heavy metals in size-fractionated road dust from a typical mining and smelting area, Gejiu, China
TL;DR: The investigation of road dust samples collected from the industrial and residential areas of Gejiu (China) allowed the evaluation of health risks from potential contamination sources and the results provide valuable information on health risk mitigation strategies for environmental managers.

Characteristics of heavy metals in size-fractionated atmospheric particulate matters and associated health risk assessment based on the respiratory deposition
TL;DR: The results of this study revealed high health risks to the residents living around the mining and smelting areas, especially the children, and it was therefore urgent to control the emission of heavy metals in the atmosphere.

Hazards of heavy metal contamination.
TL;DR: Recent data indicate that adverse health effects of cadmium exposure may occur at lower exposure levels than previously anticipated, primarily in the form of kidney damage but possibly also bone effects and fractures, and measures should be taken to reduce cadmiam exposure in the general population in order to minimize the risk of adverse health results.
Intellectual Impairment in Children with Blood Lead Concentrations below 10 μg per Deciliter
Richard L. Canfield,Charles R. Henderson,Deborah A. Cory-Slechta,Christopher Cox,Christopher Cox,Todd A. Jusko,Bruce P. Lanphear +6 more
TL;DR: Blood lead concentrations, even those below 10 microg per deciliter, are inversely associated with children's IQ scores at three and five years of age, and associated declines in IQ are greater at these concentrations than at higher concentrations.
Environmental copper: Its dynamics and human exposure issues
TL;DR: An overview of the environmental patterns and dynamics of copper from the perspective of issues that affect the ability to examine current human exposures is provided, and the needs for better information are examined.

Hair manganese and hyperactive behaviors: pilot study of school-age children exposed through tap water.
TL;DR: The hypothesis that greater exposure to Mn via drinking water would be reflected in higher Mn content in hair which, in turn, would be associated with increased level of hyperactive behaviors is tested.
Hair Manganese and Hyperactive Behaviors: Pilot Study of School-Age Children Exposed Through Tap Water
TL;DR: The findings of this pilot study are sufficiently compelling to warrant more extensive investigations into the risks of Mn exposure in drinking water.
