　　Researchers collected 10 shark fin and meat tissue samples from the Atlantic and Pacific regions and found that they contained two toxins, mercury and β-N-methylamino-L-alanine (BMAA). "Recent research shows that BMAA is associated with neurodegenerative diseases, such as Alzheimer's disease and atrophic lateral sclerosis (ALS).

　　The University of Miami (UM) Rosenstiel School of Oceanography and the School of Atmospheric Sciences and the Mirror School of L-alanine (BMAA) concentrations of various shark, mercury, β-N-methylaminofin and meat researchers According to the test, mercury and β-N-methylamino-L-alanine (BMAA) may pose a health threat to independent colleagues, and their coexistence will produce synergistic toxicity.

　　"Sharks are carnivorous animals. Shark tissues are at the top of the food chain and tend to accumulate toxins. This not only poses a threat to shark health, but also poses a health risk to complementary shark weaknesses. The main author of this study is UM Abers Ecological Sciences and Neil Hammerschlag, research assistant professor at the Decision Center and UMosensteel College.

　　Fluffy fins, cartilage, meat and other fluffy dishes are widely eaten in Asian and global Chinese societies, and are also one of the sources of traditional Chinese herbal medicine. In addition, dietary supplements containing shark cartilage are widely used worldwide.

　　Recently, scientists discovered that BMAA is contained in fluffy fin and shark cartilage supplements. The neurotoxic methylmercury is known to accumulate in the shark's body during long distances. Marsh said: "Our findings indicate that some people who eat sharks may be at risk for neurological diseases."

　　"People should be aware of this and consider restricting shark predation. Restricting shark predation not only brings health benefits to humans, but also benefits the protection of sharks. Hammerschlag said that consumer demand has fallen, and there is demand for shark meat and cartilage products.
