Background:  Mercury is a well‐known neurotoxin. There are three kinds of mercury exposure: elemental mercury poisoning, inorganic mercury poisoning and organomercury poisoning. Organomercury is the most toxic. Twenty‐four hour urine for mercury and blood mercury are the gold standards for diagnosis of mercury poisoning, including low‐level chronic mercury exposure. Other tests for mercury level are discussed. The purpose of the present paper was to review recent data on the nature… 
Measuring mercury exposure in children
TLDR
The Ng et al. meta-analysis regarding the low-level chronic exposure in children and adolescents calls into question the validity of hair mercury analysis.
Case Series of Mercury Toxicity Among Children in a Hot, Closed Environment
TLDR
N-acetylcysteine and chelation treatments were started in 21 children who had symptoms of mercury intoxication and high mercury levels in their blood or urine and no adverse effects were observed during chelation therapy.
Mercury Intoxication: Lack of Correlation Between Symptoms and Levels
TLDR
The case of an 8-year-old boy with history of mercury exposure, signs and symptoms suggestive of mercury intoxication, and good response to chelation therapy, but with only mild increase in urinary mercury levels is reported.
Hair mercury measurement in Egyptian autistic children
TLDR
To measure the concentration of total mercury trace elements in the hair of some Egyptian autistic children and to correlate these levels with severity of the disease, a highly significant increase in the mean hair mercury level in autistic patients was revealed.
Elevated Hair Mercury Levels Are Associated With Neurodevelopmental Deficits in Children Living Near Artisanal and Small‐Scale Gold Mining in Peru
TLDR
Mercury exposures related to ASGM may be harming child development in the Peruvian Amazon and children in this region may benefit from intervention to reach their full developmental potential.
Seafood Consumption and Blood Mercury Concentrations in Jamaican Children With and Without Autism Spectrum Disorders
TLDR
Jamaican children with parents who both had education up to high school are at a higher risk of exposure to mercury compared to children with at least one parent who had education beyond high school, and its association with seafood consumption and type of seafood.
Lack of Correlation Between Metallic Elements Analyzed in Hair by ICP-MS and Autism
TLDR
A meta-analysis including the present and previous similar studies excluded any association of autism with hair concentrations of mercury, cadmium, selenium, lithium and copper, and a slight association was found for lead only, but it was very weak, as strictly dependent on the worst data from one study.
Mercury fatal intoxication: two case reports.
TLDR
Because methylation of mercury in humans after exposure to metallic or inorganic mercury is almost unknown, both total mercury and methylmercury were quantified in the post-mortem samples.
Blood mercury, lead, cadmium, manganese and selenium levels in pregnant women and their determinants: the Japan Environment and Children’s Study (JECS)
TLDR
The historical trends and current predictors of the blood levels of these elements in pregnant Japanese women were revealed and the main predictors were fish consumption for Hg, maternal age and non-alcoholic beverage consumption for Pb, maternal ages for Cd, gestational age at sampling for Mn and serum protein levels for Se.
Comparison of Mercury Level of Cord Blood in Term and Preterm Neonates
Background: Mercury is a one of the pollutant that can cross the placenta. Contamination by mercury in mothers and their neonates is associated with many problems. Objectives: This study aimed to

TLDR
Observations, coupled with the ease by which samples may be collected, transported and stored, support the use of hair analysis for evaluating mercury intoxication of the human body.
Elemental mercury exposure among children of thermometer plant workers.
TLDR
It is shown that children of mercury workers are at risk for mercury exposure and potential mercury toxicity, and mercury-in-air levels measured in workers' homes were higher than those measured in control homes.
Methylmercury: significance of intrauterine and postnatal exposures.
TLDR
Based on toxicokinetics and considerations of practicability, the optimal biomarker of methylmercury exposure is the hair concentration, but whole-blood measurements of mercury are also useful, and increased use of the exposure biomarkers is encouraged.
Mercury Exposure: Current Concepts, Controversies, and a Clinic’s Experience
TLDR
It is concluded that consumption of commercially available fish can lead to elevated blood mercury concentrations and a recognized exposure source is a better predictor of significant mercury concentrations in biologic media than any particular symptom constellation.
Methyl mercury and inorganic mercury in Swedish pregnant women and in cord blood: influence of fish consumption.
TLDR
Hair analysis revealed that T-Hg closer to the scalp was lower and more closely correlated with MeHg in cord blood than T- Hg levels in segments corresponding to earlier in pregnancy, and a weak association with fish consumption was found.
Occupational and community exposures to toxic metals: lead, cadmium, mercury and arsenic.
TLDR
Children may be exposed to toxic metals from numerous sources, including contaminated air, water, soil and food, and the chronic toxic effects of lead include anemia, neuropathy, chronic renal disease and reproductive impairment.
DMSA Administration to Patients with Alleged Mercury Poisoning from Dental Amalgams: A Placebo-controlled Study
TLDR
No scientific support is provided for diagnostic or therapeutic administration of DMSA for symptoms allegedly associated with chronic mercury exposition from dental amalgam fillings, and there was no demonstrable correlation with increased urinary excretion or decreased blood concentration of mercury.
The Effects of Vitamin C Supplementation on Blood and Hair Levels of Cadmium, Lead, and Mercury
TLDR
Results indicate that vitamin C did not significantly affect levels of cadmium, lead, and mercury in either hair or blood samples.

TLDR
The study indicates that mercury accumulation in pubic hair can be reduced by dietary supplementation with small daily amounts of organic selenium in a short range of time.
High hair and urinary mercury levels of fish eaters in the nonpolluted environment of Papua New Guinea.
TLDR
Hair and urinary mercury concentrations were correlated significantly (r = .59), indicating that urinary mercury excretion was elevated because fish consumption was very high.
