HEALTH SPECIFICS: MERCURY Introduction  Mercury is a heavy liquid metal and the physical properties of mercury are; Silvery- white in liquid metal and, Solid mercury is malleable and ductile (Nduka, 2020).  Chemical symbol: Hg  The topic of mercury contamination in food (US EPA, 2019).  Mercury is a dangerous chemical for human consumption (Nduka, 2020).

SOURCES OF MERCURY • The various sources of mercury, such as coal- fired power plants, mining, and industrial waste • How mercury can enter water bodies through these sources (Naidu et al., 2019).

FISH AS A SOURCE OF MERCURY • Mercury in water bodies can accumulate in fish. • Mercury in bodies of water can accumulate in fish through a process known as bioaccumulation. • Fish higher up the food chain have higher mercury levels since they consume smaller fish that have already accumulated mercury. • Tuna, swordfish, and shark are examples of fish that are commonly contaminated with mercury (Naidu et al., 2019). • It is critical to limit consumption of high-mercury fish, particularly for pregnant women, breastfeeding mothers, and young children, because mercury exposure can end up causing developmental issues in fetuses and young children (Pradhan et al., 2020).

MERCURY IN SEAFOOD • People are exposed to mercury through consumption of contaminated seafood. • The risks associated with consuming mercury- contaminated seafood, such as neurological damage and developmental delays (Pradhan et al., 2020). • The Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA) recommend that these organizations limit their consumption of fish with high mercury levels and opt for fish and seafood with lower mercury levels (Pradhan et al., 2020).

RICE CONTAINING MERCURY  Mercury can be introduced into rice such as through contaminated soil or irrigation water.  Contaminated soil can accumulate mercury from sources such as mining and industrial activities, which makes it a major source of mercury in rice.  Mercury-contaminated irrigation water can also introduce mercury into rice (Bagchi & Bagchi, 2021). This can happen if water sources become contaminated with mercury as a result of mining, industrial activities, or natural deposits.  The risks associated with consuming mercury- contaminated rice, including kidney damage and cognitive impairment (Bagchi & Bagchi, 2021).

MERCURY IN MEAT  Examples of animals that are frequently contaminated with mercury include wild game and carnivorous fish.  Consumption of contaminated meat can expose humans to mercury (Pradhan et al., 2020) .

MERCURY'S HEALTH CONSEQUENCES  Mercury exposure has both short-term and long-term health consequences.  Mercury has the potential to harm the nervous system, immune system, and other organs in the body (Song et al., 2021).

SAFE HANDLING AND DISPOSAL PRACTICES  Explanation of the significance of closely following safe handling and disposal practices for mercury-containing products, such as not breaking them and properly disposing of them.  Recommendations for reducing exposure include selecting fish and seafood with lower mercury levels.  To prevent unnecessary mercury release, it is critical to avoid breaking and handling mercury- containing products with care. If a mercury- containing product breaks, it's important to have it cleaned thoroughly with protective gloves and clothing, and the broken pieces must be disposed of in accordance with local regulations.

HEALTH SPECIFICS: MERCURY VIDEO https://www.youtube.com/watch?v=QVu5js60PWIMercury Exposure and Health Effects (Cochrane, n.d.)

CONCLUSION • Mercury is a highly toxic chemical that could really contaminate foods like fish and rice. Contamination can occur from a variety of sources, including coal-fired power plants, mining, and industrial waste. • Mercury accumulation in fish and rice can have both short- and long-term health consequences, such as neurological problems, organ failure, and cognitive impairment. • It is critical to limit mercury exposure by avoiding contaminated seafood and rice and implementing appropriate measures to start reducing mercury pollution in the environment. • Overall, raising public consciousness regarding the risks of mercury levels and contaminations in food and taking action to protect public health is critical.
