Mystery over persistent mercury levels in tuna

Scientists and researchers around the world have been puzzled by the persistent presence of high mercury levels in tuna.

Despite efforts to regulate and monitor mercury emissions, tuna continue to show elevated levels of the toxic heavy metal.

Some theories suggest that mercury pollution in the oceans is to blame, while others point to mercury being naturally present in the food chain.

Further research is needed to fully understand the sources and implications of mercury in tuna and its potential impact on human health.

Consumers are advised to limit their intake of tuna and choose sustainable seafood options to reduce their exposure to mercury.
