Introduction

The waters of Teluk Tapian Nauli, located in Central Tapanuli Regency, are an essential area for the capture of sea products sold at Labuan Angin Fish Auction Place (TPI). Unfortunately, this location is surrounded by various industries that can cause heavy pollution, especially heavy metal pollution such as lead (Pb). This has the potential to contaminate marine biota, especially fish, which is a source of protein for local communities. The presence of lead in fish can have severe consequences on human health and the overall marine ecosystem.

Background

The study aims to analyze lead levels in fish derived from the waters of Tapian Nauli Bay and also in estuary water. This research is descriptive with fish sampling from TPI Labuan Angin and water samples taken from three different points in the estuary: right edge, middle, and left edge. The analysis of lead levels in fish and estuary water is crucial to understand the impact of industrial waste on marine biota.

Methodology

The study used a descriptive research method with fish sampling from TPI Labuan Angin and water samples taken from three different points in the estuary. The sampling method used was random sampling to ensure that the results were representative of the population.

Results

The analysis results show that the concentration of lead in the estuary water is 0.13 mg/l and 0.14 mg/l. This value clearly exceeds the quality standards determined by the Decree of the State Ministry of Environment No. 51 of 2004, which states that the maximum limit of heavy metal pollution in water is 0.008 mg/l.

In the case of lead in fish, the results of the study revealed that the fish happy (Eleutheronema tetradacptylum) contains 0.09 mg/kg, belin (mugil sp) 0.11 mg/kg, fish (paraphotosus albilabris) 0.15 mg/kg, stone head fish (pransus duodecimalis) 0.19 mg/kg, and grouper (epinephelus sp) has the highest lead level of 0.21 mg/kg. Although all of these levels are below the maximum limit set by SNI 7387: 2009, which is 0.3 mg/kg, it still needs to be aware of considering the origin of the waters exposed to industrial waste.

Discussion

The results of the study show that the concentration of lead in the estuary water exceeds the quality standards determined by the Decree of the State Ministry of Environment No. 51 of 2004. This is a worrying sign that the waters of Teluk Tapian Nauli are contaminated with heavy metals. The presence of lead in fish can have severe consequences on human health and the overall marine ecosystem.

Conclusion

In conclusion, the analysis of lead levels in fish in Tapian Nauli's waters shows that although lead levels in fish are still below standard, estuary water pollution that exceeds the threshold is very worrying. Further research is needed to monitor these changing heavy metal levels regularly and involve the community in spreading information about the potential dangers of this pollution.

Recommendations

Based on the results of the study, the following recommendations are made:

The government and authorities should conduct supervision and control of the disposal of industrial waste around Tapian Nauli's waters.
The community is advised not to consume fish from the region, especially until adequate precautions are taken to reduce the risk of exposure to this heavy metal.
Further research is needed to monitor these changing heavy metal levels regularly and involve the community in spreading information about the potential dangers of this pollution.

Limitations

The study has some limitations that need to be addressed in future research. The study only analyzed lead levels in fish and estuary water, and did not consider other heavy metals that may be present in the waters. The study also did not consider the impact of lead on human health and the overall marine ecosystem.

Future Research Directions

Based on the results of the study, the following future research directions are suggested:

Conducting further research to monitor changing heavy metal levels regularly.
Involving the community in spreading information about the potential dangers of this pollution.
Conducting research to understand the impact of lead on human health and the overall marine ecosystem.
