Fish then eat the algae, absorbing and retaining its mercury. Fish that contain high levels of mercury include shark, orange roughy, swordfish and ling. This process is called biomagnification (11). Environmental issues cover a broad range of areas, but medical cases that are associated with pollutants released into the environment by factories or construction areas cause public health issues that affect not only the environment but also human well-being. Eat up to 2 meals per week of fish from the LOW in mercury list. Recent studies also link exposure to heavy metals such as mercury to conditions like Alzheimers, Parkinsons, autism, depression, and anxiety (18). Here are the average levels in different types of fish and seafood, from highest to lowest (5): Different types of fish and other seafood contain varying amounts of mercury. A fully grown fish can reach about 40 cm length and weigh about one and half kilogram. When it comes to fish, there is much debate on whether the benefits outweigh potential safety concerns. Thus, bighead carp gather more mercury by eating large amounts of small plankton, as well as sucking up sediments that collect a sizable amount of methyl mercury. According to a CNN report, this type of fish has extremely high levels of metal mercury that can eventually cause coordination loss, blindness and even death, depending on the amount or portion ingested. It was found that the Chisso Corporation, a petrochemical company and maker of plastics such as vinyl chloride, had been discharging heavy metal waste into the sea for decades. However, the health benefits of eating fish may outweigh these risks as long as you limit your intake of high-mercury fish. In Tamil Nadu, it is known locally as the pappan or pappa[5] In Goa, the fish is known as kalundar. [38], Fish that consume their prey in a certain manner may contain much higher concentrations of mercury than other species. [8] The older that such fish become, the more mercury they may have absorbed. Anthropogenic sources and places where mercury is released or used as a solid or vapor puts these has caused fatigue, dizziness, hyperhidrosis, chest congestion, and loss of motor skills. One animal study revealed that exposure to even low doses of methylmercury during the first 10 days of conception impaired brain function in adult mice (26). [9], There are three types of mercury emission: anthropogenic, re-emission, and natural, including volcanoes and geothermal vents.

[citation needed]. [6] Methyl mercury is not soluble and therefore not excreted. Medical research reported that the children who received doses of these medicines experienced physical symptoms such as "drooling, irregular arm movements, and impaired gait". Another commonly eaten fish, albacore ("white") tuna, has more mercury than canned light tuna. [31], Certain countries have cultural differences that lead to more fish consumption and therefore more possible exposure to seafood methylmercury. [30] Multiple studies have been done, such as those in New Jersey and Sweden, that take into account selenium as well as mercury levels. Such mercury from gold mines is specifically known to contribute to biomagnification in aquatic food chains.[14]. It eats mainly aquatic plants, including filamentous algae and diatoms, but it consumes the occasional mollusk and other animal matter.

A study in 129 Brazilian adults found that higher levels of mercury in hair were associated with a decrease in fine motor skills, dexterity, memory, and attention (17). They found that mercury levels averaged 45 ppb (parts per billion) in canned salmon and 55 ppb in mackerel, compared with as much as 340 ppb in tuna in oil. Additionally, the study noted that higher fish intake was linked to higher mercury levels. However, some fish may contain mercury or other harmful chemicals at sufficiently high levels to be a concern. Analysis also shows increase of mercury content in the hair of humans who eat fish on a daily basis in the Amazon. Coal contains mercury as a natural contaminant. Karimeen pollichathu, a fried dish, is a delicacy served in restaurants. In addition to enacting legislation controlling the mercury levels in potential pollutants, Japan has directly influenced the environment by issuing regulations setting acceptable levels of environmental mercury pollution. [10] Much of the mercury deposited in the oceans is re-emitted, however; as much as 300 metric tons is converted into methyl mercury. The unborn baby is most sensitive to the effects of mercury, particularly during the third and fourth months of gestation.

A study that was led by scientists from Harvard University and U.S. Geological Survey has determined that in the next several decades there will be a 50 percent increase in mercury levels. [19], While various studies have shown high concentrations of mercury accumulated in fish, medical cases often go unreported and pose a difficulty in correlating mercury in fish with human poisoning. Most of this mercury pollution can be eliminated if pollution-control devices are installed. [29] Additionally, children undergo fast growth that causes them to be more susceptible to damaging exposure to methylmercury, as well as the long term consequences of such exposure during childhood development. [24], Most cases that arise are due to work exposure or medicinal poisoning.
