Cadmium Heavy Metal Bioaccumulation (CD) on the Root of the Bark and Leaf of Rhizopora Apiculata in the Lubuk Kertang Mangrove Ecotourism Area

Introduction

The Lubuk Kertang Mangrove Ecotourism area in Langkat Regency, North Sumatra, is a vital ecosystem that provides numerous benefits to the environment and the local community. However, the presence of cadmium heavy metal (CD) in this ecosystem poses a significant threat to the health of mangrove plants and surrounding marine biota. This study aims to investigate the bioaccumulation of CD in the roots, bark, and leaves of Rhizopora apiculata in the Lubuk Kertang Mangrove Ecotourism area.

Background

Cadmium (CD) is a toxic heavy metal that can accumulate in the tissue of living organisms, including plants and animals. It has been reported that CD pollution can cause various health problems, such as organ damage, reproductive disorders, and even death. The World Health Organization (WHO) has established a quality standard threshold for CD in aquatic plants and water, which is 0.12-2.527 mg/kg.

Methodology

This study was conducted in July-August 2020 by taking root samples, bark, leaves, sediments, and water at three stations in the Lubuk Kertang Mangrove Ecotourism area. Each station had three repetitions, and the samples were analyzed for CD content using a spectrophotometer.

Results

The results of this study showed that the CD content in the roots, bark, and leaves of Rhizopora apiculata at three stations had an average below 0.12-2.527 mg/kg. Station III had the highest CD content, which was 2,527 mg/kg on roots, 1,043 mg/kg on the bark, and 0.150 mg/kg on the leaves. The CD content in these three parts of the plants exceeded the WHO quality standard threshold.

Analysis of the CD content on sediment at three stations showed results between 0.12-4,137 mg/L, with the highest content at station III, which was 4,137 mg/kg. However, the CD content in sediment was still below the quality standard of IADC/Ceda (1997).

The CD content in water at stations I and II was detected below 0.002 mg/L, while station III showed results of 1,049 mg/L. This indicates that the CD content in water at Station III exceeded the LH Kepmen No. quality standard threshold No. 51 of 2004.

Discussion

The results of this study indicate that the bioaccumulation of CDs in the Lubuk Kertang mangrove ecosystem has reached an alarming level. This has the potential to endanger the health of mangrove ecosystems and surrounding marine biota. The CD content in the roots, bark, and leaves of Rhizopora apiculata exceeded the WHO quality standard threshold, indicating that the ecosystem is heavily polluted.

The CD content in sediment was still below the quality standard of IADC/Ceda (1997), but the CD content in water at Station III exceeded the LH Kepmen No. quality standard threshold No. 51 of 2004. This suggests that the CD pollution in the Lubuk Kertang waters may originate from various sources, such as industrial activities, agriculture, and domestic waste disposal.

Impact of Bioaccumulation

CD is a very toxic heavy metal and has high bioaccumulation properties. This means that the heavy metal can accumulate in the tissue of living organisms, including mangrove plants, and not easily released. Over time, the concentration of CDs in the body of living organisms will increase, so that it has the potential to cause various health problems, such as organ damage, reproductive disorders, and even death.

Sources of Pollution

CD pollution in Lubuk Kertang waters may originate from various sources, such as industrial activities, agriculture, and domestic waste disposal. It is essential to conduct further research to identify the main source of CD pollution in the area.

The Importance of Mangrove Conservation

Mangrove ecosystems have an important role in maintaining environmental balance, such as absorbing carbon, protecting the coastline from abrasion, and becoming a habitat for various marine life. CD pollution can threaten the preservation of mangrove ecosystems.

Mitigation Efforts

Mitigation efforts are needed to reduce CD pollution in Lubuk Kertang waters. Several steps that can be taken include:

Development of Environmental Rama Technology: Industry around the waters of Lubuk Kertang needs to apply environmentally friendly technology to reduce CD emissions.
Monitoring and Control: Periodic monitoring of CD levels in waters and mangrove ecosystems is needed to monitor the level of pollution and take appropriate action.
Increasing Public Awareness: Increasing public awareness about the importance of maintaining the preservation of mangrove ecosystems and the dangers of CD pollution can help reduce activities that have the potential to pollute the environment.

Conclusion

The results of this study showed the need for serious attention to CD pollution in the waters of the Lubuk Kertang mangrove ecotourism. Comprehensive mitigation and conservation efforts are needed to protect this vital mangrove ecosystem from the threat of pollution.
