The Toxicological Effect of Mercury and It’s Implicit Impact on Humans
The toxicological effect of Mercury is known as crucial. Mercury is very harmful to our body, and the nervous system is very sensitive to all forms of it. Methylmercury and metallic mercury vapors are more harmful than other forms, because more mercury in these forms reaches the brain.
Methylmercury Poisoning Impact on Humans
Central nervous system effects such as:
Mercuric chloride effect:
The Toxicological Effect Engendered on Absorbing Mercury Impact on Humans
To Young Children
Mercury’s harmful effects that may be passed from the mother to the fetus include brain damage, mental retardation, in coordination, blindness, seizures, and inability to speak
Mercury in the mother's body passes to the fetus and may accumulate there.
Mercury can pass to a nursing infant through breast milk.
Many mothers refuse to provide their infants the flu vaccine( which is recommended from 6-23 months), which is called Fluzone.
Fluzone is a trivalent vaccine grown in chicken eggs. Harvested with formaldehyde and containing the recommended ratio of 15 ug of each of the three prototype viral strains, each dose of Fluzone also contains 25 ug of mercury
Fish Consumption Limits Nursing Mothers
EPA indicated that the typical U.S. consumer was not in danger of consuming harmful levels of methyl mercury from fish.
This advice is appropriate for typical consumers who eat less than 10 grams of fish and shellfish per day with mercury concentrations averaging between 0.1 and 0.15 ppm.
Eating more fish than is typical or eating fish that are more contaminated, can increase the risk to a developing infant.
Consumption Limits Calculation Nursing Mothers
The number of allowable fish meals per month based on the ranges of methylmercury in the consumed fish tissue. The following assumptions were used to calculate the consumption limits:
Consumer adult body weight of 70 kg
Average fish meal size of 8 oz (0.227 kg)
Time-averaging period of 1 mo (30.44 d)
Is a proven indirect method for assessing mercury toxicity.
measure mercury in the blood, urine or feces, or in tissues (e.g., hair and nail).
Demonstrate the role of mercury in populations of autistic children
Mercury can have a harmful effect on mothers, infants, and adults in general
Consuming a reasonable amount of it can have minimum effect on our body
Excessive intake of mercury might lead to serious health problems.
Methylmercury and metallic mercury vapors are more harmful than other forms
Mercury’s harmful effects that may pass from mother to fetus and can cause to many consequences like brain damage, mental retardation, in coordination, blindness, seizures, and death in sever cases
Urinary Porphyrin Profil Analysis is a proven indirect technique for measuring Mercury toxicity.
