Fish found in the sea not only have plastic content inside, as some studies have reported, recently the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) They warned that almost all seafood contains traces of mercury.
Fish and shellfish with high levels of mercury
Shark meat, swordfish, mackerel or lofolátilo contain high levels of mercury and therefore should not be included in the diet.
Mercury damages the nervous system, brain functions, DNA and chromosomes, reactions, skin irritation, fatigue, headache; negative effects on reproduction, sperm damage, birth defects and abortions.
The risks of mercury in fish depend on Chile Mobile Number List the amount consumed and the levels they contain. Fish and shellfish with high levels of mercury harm the fetus in the first period of gestation or the developing nervous system of a young child, the two agencies warned.
Therefore, it is important that women of childbearing age, pregnant women, mothers of infants and young children do not consume some types of fish.
Shellfish and fish that are frequently eaten low in mercury are: shrimp, canned tuna, salmon, pollock, and catfish.
According to experts, it is important to check local advisories about the safety of fish living in rivers and coastal areas.
Mercury in humans
Shellfish consumption is the main source of mercury in humans. Various studies affirm that almost all people have at least minimal amounts of mercury in their bodies, which reflects the widespread presence of this compound in the environment and human exposure through the consumption of fish and shellfish.
People can be exposed to mercury in any of its forms under different cirxstances.
In the fetus, infant and child, the main effect of mercury is the alteration of neurological development.
Climate change also affects
Rising ocean temperatures are causing an increase in mercury in fish such as cod, bluefin tuna and swordfish.
According to a study published in the scientific journal Nature , the first of its kind, it simulates how environmental factors, including rising sea temperatures and overfishing, affect methylmercury levels in fish.
Led by the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the Harvard TH Chan School of Public Health (HSPH), the study found that after achieving some success in regulating methylmercury levels in fish, high temperatures are causing them to increase again.
" This research is an important advance in understanding how and why ocean predators, such as tuna and swordfish, are acxulating mercury," said Professor of Environmental Chemistry Gordon McKay at SEAS and HSPH, and lead author of the paper. , Elsie Sunderland.
Methylmercury acxulates in food webs, meaning that organisms at the top of the food chain have higher levels of this material than those at the bottom.
The study collected and analyzed 30 years of data from the Gulf of Maine ecosystem, including an exhaustive analysis of the stomach contents of two marine predators, the Atlantic cod and the stickleback, from the 1970s to the 2000s.
According to Sunderland, climate change will increase human exposure to methylmercury through seafood, which is why it is important to protect ecosystems and human health.
