Analysis of Kadmium Heavy Metal Content (CD) in Blood Shells and Water in the Waters of the Asahan River, Tanjung Balai City in 2020

Introduction

The Asahan River, flowing through the city of Tanjung Balai, is a vital water source for the community. However, the river's potential for heavy metal pollution poses a significant threat to human health. The disposal of household waste into the river and the mobility of fishing boats that dispose of waste directly into the river are major factors contributing to pollution. As a result, aquatic biota such as blood shells can absorb heavy metals, making them a potential threat to human health. This study aims to determine the levels of CD in water and blood shells in the waters of the Asahan River, Tanjung Balai City, in 2020.

Background

Heavy metal pollution in water bodies is a growing concern worldwide. The Asahan River, being a vital water source, is susceptible to pollution from various sources, including household waste and fishing activities. The community's reliance on the river for fishing and other economic activities makes it essential to monitor the water quality and the levels of heavy metals present in the water and aquatic biota. Blood shells, being a common food source for the community, are particularly vulnerable to heavy metal pollution.

Methodology

This study employed a descriptive survey method to collect primary data through the examination of blood shells and water samples in the Medan City Health Laboratory. The data were analyzed using bivariate analysis to determine the levels of CD in water and blood shells. The results of the study are presented below.

Results

The results of the study showed that the CD content in sea water in the waters of the Asahan River in Tanjung Balai City was <0.0020 mg/L. This value is below the sea quality standard according to the Decree of the State Minister for Environment Number 51 of 2004 (0.001 mg/L). However, the CD levels in blood shells reached 0.08 mg/kg, which is a significant concern.

Discussion

Although the CD content in sea water is still below the sea quality standard, the CD levels in blood shells need serious attention. The calculation of weekly intake limits for blood shells in one day is 5,6875 kg. Analysis of the Risk of CD Intakes in Blood Shells shows a value of 0.11 mg/kg/day with RQ> 1. This means that the consumption of blood shells from the waters of the Asahan River in Tanjung Balai City has the potential to pose health risks for the community.

Conclusion

The CD levels in blood shells are still below the SNI threshold value No. 7387: 2009 (1.0 mg/kg). However, given the significant potential risk, preventive steps are needed to prevent increased CD levels in the future. The Office of Health and Environmental Environment of Tanjung Balai City must increase the control efforts of waste disposal and activities around the waters. It is essential to remember that consumption of blood shells contains health risks if they come from polluted waters. People are advised to be more careful in choosing a source of blood shells and prioritizing consumption from waters that are guaranteed cleanliness.

Recommendations

Based on the findings of this study, the following recommendations are made:

Increase control efforts: The Office of Health and Environmental Environment of Tanjung Balai City must increase the control efforts of waste disposal and activities around the waters.
Monitor water quality: Regular monitoring of water quality is essential to ensure that the CD levels in water and blood shells do not exceed the safe limits.
Educate the community: The community must be educated on the risks associated with consuming blood shells from polluted waters and the importance of choosing a safe source of blood shells.
Implement preventive measures: Preventive measures such as waste management and proper disposal of waste must be implemented to prevent increased CD levels in the future.

Limitations

This study has several limitations, including:

Limited sample size: The sample size of this study was limited, which may not be representative of the entire population.
Limited data collection: The data collection was limited to a single point in time, which may not reflect the long-term trends in CD levels in water and blood shells.
Limited analysis: The analysis of the data was limited to bivariate analysis, which may not capture the complex relationships between the variables.

Future Research Directions

Future research should focus on:

Long-term monitoring: Long-term monitoring of water quality and CD levels in water and blood shells is essential to understand the trends and patterns of heavy metal pollution.
Multivariate analysis: Multivariate analysis should be employed to capture the complex relationships between the variables and to identify the factors that contribute to heavy metal pollution.
Community engagement: Community engagement and education are essential to raise awareness about the risks associated with consuming blood shells from polluted waters and to promote the importance of choosing a safe source of blood shells.

Conclusion

In conclusion, this study highlights the importance of monitoring water quality and CD levels in water and blood shells in the waters of the Asahan River, Tanjung Balai City. The findings of this study suggest that the CD levels in blood shells are a significant concern and that preventive steps are needed to prevent increased CD levels in the future. The recommendations made in this study are essential to ensure that the community is protected from the risks associated with consuming blood shells from polluted waters.
Frequently Asked Questions (FAQs) about Kadmium Heavy Metal Content (CD) in Blood Shells and Water in the Waters of the Asahan River, Tanjung Balai City in 2020

Q: What is Kadmium Heavy Metal Content (CD)?

A: Kadmium (CD) is a toxic heavy metal that can be found in water and aquatic biota, including blood shells. It is a known carcinogen and can cause a range of health problems, including kidney damage and cancer.

Q: Why is CD a concern in the Asahan River?

A: The Asahan River is a vital water source for the community, and the presence of CD in the water and blood shells poses a significant threat to human health. CD can accumulate in the bodies of aquatic biota, including blood shells, and can be transferred to humans through consumption.

Q: What are the safe limits for CD in water and blood shells?

A: The safe limits for CD in water and blood shells vary depending on the source and the intended use. However, the Decree of the State Minister for Environment Number 51 of 2004 sets a maximum allowable limit of 0.001 mg/L for CD in sea water. For blood shells, the SNI threshold value No. 7387: 2009 sets a maximum allowable limit of 1.0 mg/kg.

Q: What are the health risks associated with consuming blood shells from polluted waters?

A: Consuming blood shells from polluted waters can pose a range of health risks, including kidney damage, cancer, and other health problems. The risk of health problems increases with the level of CD in the blood shells.

Q: How can I protect myself from the health risks associated with consuming blood shells from polluted waters?
