Available studies support the known association between fish consumption and exposure to methylmercury.
For most countries, the main source of human exposure to methylmercury is through the consumption of fish.
Exposure to methylmercury occurs from eating fresh or marine water fish and animals that feed on fish.
The results confirmed the high fish consumption in Spain and, correspondingly,a high exposure to methylmercury.
He stressed that exposure to methylmercury was particularly dangerous for young children and pregnant women.
Option selection In general, there are two strategies to reduce the public's exposure to methylmercury in fish.
Another risk management strategy is to reduce potential exposure to methylmercury through fish consists of setting maximum acceptable concentration limits.
Differences of exposure were noted in various European countries- for example,exposure to methylmercury.
Bacteria in aquatic systems convert a small proportion of the deposited Hg to methylmercury(MeHg), which bioaccumulates in fish inorganic Hg does not bioaccumulate.
Once incorporated in the hair, mercury does not return to the blood,thus it provides a good long-term marker of exposure to methylmercury.
As described in Chapter 2, the general population is primarily exposed to methylmercury through the diet, especially from fish.
Once incorporated in the hair, mercury does not return to the blood, thus it provides a good long-term marker of exposure to methylmercury. .
For example, prenatal exposure to methylmercury from contaminated seafood can result in delayed cognitive development with effects that can persist into adulthood 2.
Reduction of mercury in the environment by controlling emissions can also decrease exposure to methylmercury on a long-term basis.
People are exposed to methylmercury mainly through their diet, especially through the consumption of freshwater and marine fish and consumption of other animals that consume fish such as marine mammals.
It aims to provide guidance on estimating exposures to mercury through biomonitoring and exposures to methylmercury using data on dietary fish intake.
People are exposed to methylmercury primarily through their diet, especially through the consumption of fish and other marine species, as well as through the consumption of rice when it is grown in a methylmercury-rich environment.
Nonetheless, people who consume high amounts of contaminated fish ormarine mammals may be highly exposed to methylmercury, and therefore may be at risk.
Some populations have greater exposure to methylmercury because of the quantity and type of fish, shellfish, and marine mammal consumed, and the location where the fish, shellfish and marine mammals are harvested.
It aims to provide guidance on estimating exposures to mercury through biomonitoring and to methylmercury using data on dietary fish intake.
This biomonitoring survey will assess prenatal exposure to methylmercury by measuring total mercury in maternal hair and, when there are known local sources of exposure to inorganic or elemental mercury, mercury in maternal urine and in cord blood.
The utility HAP report indicated that there was a plausible link between Hg emissions from coal-fired boilers andhealth risks posed by indirect exposure to methylmercury.
Because fish consumption dominates the pathway for exposure to methylmercury for most human populations, many governments provide recommendations or legal limits for the maximum allowable amount of mercury and/or methylmercury in fish to be sold on the market.
It should also be notedthat inorganic mercury is a contaminant of food, but exposure is considered less important because of the lower toxicity of inorganic mercury compared to methylmercury.
Atmospheric Hg that is transferred to aquatic systems through dry andwet deposition mechanisms is converted from an inorganic form to methylmercury(MeHg) by microbes in the water and sediments of wetlands, lakes, reservoirs, rivers, estuaries and oceans.
The Working Group suggested to look at methylmercury concentrations in different age groups of toothfish to see whether there was evidence of age-related susceptibility to methylmercury accumulation.
In the case of human exposure to methylmercury, human biomonitoring through hair analysis is recommended, and is preferred to monitoring of mercury levels in fish because the latter provides an indirect indicator of human exposure with greater inherent uncertainty than hair analysis.
Emissions of mercury to the air from both anthropogenic andnatural sources are in the inorganic form, which can be biologically converted to methylmercury in soil and water.
Estimating exposure to methylmercury in fish can be used as a cost-effective tool by risk managers to assess the risk of methylmercury to susceptible populations, but broader health benefits, as well as the social, cultural and economic considerations of fish consumption, need to be kept in mind when considering risk management options.
The ultimate goal of these strategies is to change patterns of consumption so that people at risk can continue to eat fish and enjoy its health benefits,while also reducing their exposure to methylmercury.
