Analysis of Lead Heavy Metal Content (Pb) and Copper (Cu) in the Tahaii River Water Flow, Tanjung Morawa District

Introduction

The quality of water in rivers and streams is a crucial aspect of maintaining a healthy ecosystem and ensuring the well-being of the surrounding communities. The presence of heavy metals such as lead (Pb) and copper (Cu) in water can have devastating effects on both the environment and human health. This study aims to analyze the content of lead metals (Pb) and copper (Cu) in the Tahaii River water flow, Tanjung Morawa District, and determine the quality of raw water based on the results of the analysis.

Background

The Tahaii River is a vital water source for the surrounding communities, providing drinking water, irrigation for agricultural activities, and supporting aquatic life. However, the increasing presence of heavy metals in the river water poses a significant threat to the ecosystem and public health. Lead (Pb) and copper (Cu) are two of the most common heavy metals found in water, and their presence can have severe consequences.

The Importance of Heavy Metal Analysis

Heavy metal analysis is crucial in determining the quality of water and identifying potential sources of pollution. Lead (Pb) and copper (Cu) are known to have toxic properties that can cause various health problems, such as nerve damage, impaired kidney function, and growth problems in children. The presence of these metals in water can also affect the aquatic life, leading to the decline of fish populations and other aquatic species.

Methodology

This study was conducted in February to March 2014 in the Tahaii River, Tanjung Morawa District. Three stations were observed, with repetition three times every ten days. The observed parameters included physical-chemical-chemical parameters, and heavy metals were analyzed using atomic absorption spectrophotometry (AAS).

Results

The results of the analysis show that the lead metal content of lead (Pb) in water ranges from 0.074 to 0.176 mg/L, while the content of copper heavy metals (Cu) ranges from 0.186 to 0.423 mg/L. These findings indicate that the heavy metal content of Pb and Cu in the Tahaii River flow has exceeded the quality standards set by Government Regulation No. 82 of 2001.

Discussion

The presence of lead (Pb) and copper (Cu) in the Tahaii River water flow is a cause for concern. These metals can have devastating effects on both the environment and human health. The sources of these metals in the river water are likely to be industrial activity, waste disposal, and the use of paint containing lead. Copper (Cu) usually comes from agricultural activities and domestic waste.

The Impact of Heavy Metals on the Environment and Human Health

The presence of heavy metals in water can have severe consequences on both the environment and human health. Lead (Pb) and copper (Cu) are known to have toxic properties that can cause various health problems, such as nerve damage, impaired kidney function, and growth problems in children. The presence of these metals in water can also affect the aquatic life, leading to the decline of fish populations and other aquatic species.

Recommendations for Environmental Management

From the results of this study, there are several recommendations that need to be considered. First, the importance of routine monitoring of river water quality in order to detect and overcome early pollution problems. Second, the need for education to the public about the negative impact of using hazardous chemicals and the importance of maintaining the cleanliness of the environment around the river.

Increasing Supervision of Industry and Agricultural Activities

The regional government should increase supervision of the industry and agricultural activities around the Tahaii River, so that there is no waste disposal that can damage water quality. The implementation of environmentally friendly policies and good waste treatment will be very helpful in maintaining the balance of ecosystems and the health of the community around the region.

Conclusion

The presence of lead (Pb) and copper (Cu) in the Tahaii River water flow is a cause for concern. These metals can have devastating effects on both the environment and human health. This study highlights the importance of routine monitoring of river water quality and the need for education to the public about the negative impact of using hazardous chemicals. The regional government should also increase supervision of the industry and agricultural activities around the Tahaii River to prevent waste disposal that can damage water quality.

Future Research Directions

Future research should focus on identifying the sources of lead (Pb) and copper (Cu) in the Tahaii River water flow and developing strategies to mitigate their effects. Additionally, research should be conducted on the impact of heavy metals on the aquatic life and human health in the surrounding communities.
