Analysis of Kadmium Heavy Metal Content (CD) in Fish Meat Happy (Eleutheronema Tetradactylum) in Belawan Waters of North Sumatra Province

Introduction

Fish happy (Eleutheronema tetradactylum) is a highly sought-after demersal fish in the market, particularly in the city of Medan. According to data from PPS Belawan, fish production of happy in 2015 reached 1,564 tons, up from 1,116 tons in the previous year (2014). The location of this fish habitat, which is close to the beach, makes it vulnerable to pollution, especially from waste that is discharged into the waters. Therefore, it is essential to analyze heavy metal content, especially cadmium (CD), in fish happy to ensure its safety for human consumption.

The Importance of Heavy Metal Analysis in Fish

Heavy metal analysis is crucial in determining the safety of fish for human consumption. Cadmium, in particular, is a toxic heavy metal that can cause various health problems, including kidney damage and an increased risk of cancer, if accumulated in the human body. Long-term exposure to cadmium can have severe consequences, making it essential to monitor and regulate its levels in fish. Sources of cadmium pollution in waters generally come from industrial activities, agriculture, and domestic waste.

Research Significance

The analysis of cadmium content in fish happy is significant for several reasons. Firstly, it helps to ensure the safety of fish for human consumption. Secondly, it provides valuable information on the quality of fish and the impact of heavy metal pollution on the environment. Finally, it contributes to public health protection and the sustainability of fisheries resources.

Methods Used in the Study

The method used in this study is sampling, where three different locations were selected to obtain varied data. The analysis showed that the cadmium content in fish happy at station I was 0.066 mg/kg, at station II was 0.10 mg/kg, and at station III reached 0.103 mg/kg. These figures need to be considered, especially because the quality standards set are 0.1 mg/kg.

Results and Discussion

The results of the study showed that the cadmium content in fish happy varies between sampling locations. Although some numbers are below the quality standard, it is essential to monitor regularly to the quality of water and fish in this region to prevent higher accumulation of heavy metals in the future. The variation in cadmium content between locations may be due to several factors, including the location of the fish habitat, water circulation, and the presence of pollutants.

Conclusion and Suggestions

From this study, it can be concluded that the cadmium content in fish happy in Belawan waters varies between sampling locations. Although some numbers are below the quality standard, it is essential to monitor regularly to the quality of water and fish in this region to prevent higher accumulation of heavy metals in the future. In addition, counseling to fishermen and the community about the importance of heavy metals and their impact on health becomes a wise step to increase health awareness.

Recommendations for Future Research

With increasing attention to this kind of research, it is hoped that there will be further action to maintain the cleanliness of the water and the quality of fishery products that are safe and high quality. Future research should focus on monitoring the quality of water and fish in this region regularly to prevent higher accumulation of heavy metals. Additionally, studies should be conducted to identify the sources of cadmium pollution and to develop strategies to mitigate its impact on the environment.

Implications for Public Health and Fisheries Resources

The analysis of cadmium content in fish happy has significant implications for public health and fisheries resources. Firstly, it highlights the importance of monitoring the quality of fish and water to prevent the accumulation of heavy metals. Secondly, it emphasizes the need for counseling to fishermen and the community about the importance of heavy metals and their impact on health. Finally, it contributes to the sustainability of fisheries resources by ensuring the safety of fish for human consumption.

Conclusion

In conclusion, the analysis of cadmium content in fish happy in Belawan waters is essential to ensure the safety of fish for human consumption. The study highlights the importance of monitoring the quality of water and fish in this region to prevent higher accumulation of heavy metals. Additionally, it emphasizes the need for counseling to fishermen and the community about the importance of heavy metals and their impact on health. With increasing attention to this kind of research, it is hoped that there will be further action to maintain the cleanliness of the water and the quality of fishery products that are safe and high quality.

Frequently Asked Questions (FAQs) about Cadmium Content in Fish Happy (Eleutheronema Tetradactylum)

Q: What is cadmium and why is it a concern in fish?

A: Cadmium is a toxic heavy metal that can cause various health problems, including kidney damage and an increased risk of cancer, if accumulated in the human body. It is a concern in fish because it can be present in high levels in fish that are caught in polluted waters.

Q: What are the sources of cadmium pollution in waters?

A: Sources of cadmium pollution in waters generally come from industrial activities, agriculture, and domestic waste. These activities can release cadmium into the water, where it can accumulate in fish and other aquatic organisms.

Q: How can I tell if the fish I am eating is safe from cadmium contamination?

A: The best way to ensure that the fish you are eating is safe from cadmium contamination is to choose fish that are caught in waters that are known to be free from pollution. You can also check with local authorities or fishing organizations to see if there have been any reports of cadmium contamination in the waters where the fish were caught.

Q: What are the health effects of cadmium exposure?

A: Long-term exposure to cadmium can cause various health problems, including kidney damage and an increased risk of cancer. It can also cause other health problems, such as anemia and bone disease.

Q: How can I reduce my exposure to cadmium?

A: There are several ways to reduce your exposure to cadmium. One way is to choose fish that are caught in waters that are known to be free from pollution. You can also limit your consumption of fish that are high in cadmium, such as those that are caught in polluted waters. Additionally, you can take steps to reduce your exposure to cadmium in your daily life, such as avoiding exposure to cadmium-containing products and following proper handling and cooking procedures for fish.

Q: What can be done to reduce cadmium pollution in waters?
