Analysis of Iron Levels (Fe) and Zinc (Zn) in Industrial Wastewater at the Class 1 Medan Health and Disease Control Center (BTKLPP)

Introduction

Industrial waste management is a crucial aspect in protecting the environment. The Class 1 Medan Health Engineering and Disease Control Center (BTKLPP) has conducted an analysis of iron and zinc (Zn) in industrial wastewater to assess the impact of industrial waste on ecosystems. This analysis aims to determine whether the waste meets the requirements to be discharged into the river. The method used for this analysis is ICP (Inductively Coupled Plasma), which is known to be accurate in measuring heavy metal concentrations.

Industrial waste management is a complex issue that requires careful consideration of various factors, including the type of waste, the concentration of pollutants, and the potential impact on the environment. Heavy metals such as iron and zinc are commonly found in industrial waste and can have a negative impact on the environment and human health if not managed properly. Therefore, it is essential to conduct regular analysis of heavy metal content in industrial waste to ensure that it meets the required standards.

The Importance of Testing Heavy Metal Content

Testing heavy metal content in wastewater is very important because metals such as iron and zinc can have a negative impact on the environment and human health. Excessive amounts of iron can cause changes in water quality and have an impact on aquatic life. In addition, zinc contained in wastewater can also be toxic to water organisms if the concentration is high. The analysis of heavy metal content in industrial waste is crucial in determining whether the waste meets the required standards for discharge into the river.

Heavy metal pollution is a significant environmental concern that can have severe consequences on human health and the ecosystem. Exposure to heavy metals can cause a range of health problems, including cancer, neurological damage, and reproductive issues. Therefore, it is essential to conduct regular analysis of heavy metal content in industrial waste to ensure that it meets the required standards.

Environmental and Health Impact

Although the analysis results show that the iron and zinc content in industrial waste meets the standards, it is essential to continue to conduct routine supervision. Increased heavy metal content can be caused by factors such as changes in industrial processes, the use of different raw materials, or leakage in the disposal system. Therefore, monitoring periodically is very necessary to avoid potential pollution that can harm the ecosystem and public health.

The environmental and health impact of heavy metal pollution can be severe and long-lasting. Exposure to heavy metals can cause changes in water quality, affect aquatic life, and contaminate soil and air. In addition, heavy metal pollution can also have a negative impact on human health, including cancer, neurological damage, and reproductive issues. Therefore, it is essential to conduct regular analysis of heavy metal content in industrial waste to ensure that it meets the required standards.

Methodology

The analysis of iron and zinc content in industrial waste was conducted using the ICP (Inductively Coupled Plasma) method. This method is known to be accurate in measuring heavy metal concentrations and is widely used in environmental monitoring. The ICP method involves the use of a plasma torch to ionize the sample, which is then measured using a mass spectrometer.

The analysis results show iron content (Fe) for three samples, namely: sample 1: 1,32159 mg/l, sample 2: 1,33764 mg/l, and sample 3: 1,31758 mg/l. While zinc content (Zn) for these samples is: sample 1: 0.01541 mg/l, sample 2: 0.01394 mg/l, and sample 3: 0.02478 mg/l. From the data obtained, it can be concluded that the iron and zinc content in this wastewater is far below the maximum limit set by the Decree of the Minister of Environment KEP-51/MenLH/10/1995, which is 5 mg/L.

Results and Discussion

The analysis results show that the iron and zinc content in industrial waste meets the required standards for discharge into the river. However, it is essential to continue to conduct routine supervision to ensure that the waste meets the required standards. Increased heavy metal content can be caused by factors such as changes in industrial processes, the use of different raw materials, or leakage in the disposal system.

The results of this analysis are consistent with previous studies that have shown that the iron and zinc content in industrial waste is generally below the maximum limit set by the Decree of the Minister of Environment KEP-51/MenLH/10/1995. However, it is essential to continue to conduct regular analysis of heavy metal content in industrial waste to ensure that it meets the required standards.

Conclusion

Analysis of iron levels (Fe) and zinc (Zn) at the Class 1 Medan Health and Disease Control Center shows that the industrial waste tested is safe to be discharged into rivers, based on established standards. However, it is essential for the authorities and the industry to continue to monitor the levels of heavy metals so that there is no dangerous pollution in the future. Thus, preventive steps can be taken to maintain the quality of the environment and public health.

In conclusion, the analysis of iron and zinc content in industrial waste is essential in determining whether the waste meets the required standards for discharge into the river. The results of this analysis show that the iron and zinc content in industrial waste meets the required standards. However, it is essential to continue to conduct routine supervision to ensure that the waste meets the required standards.

Recommendations

Based on the results of this analysis, the following recommendations are made:

Continue to conduct regular analysis of heavy metal content in industrial waste to ensure that it meets the required standards.
Implement measures to prevent leakage in the disposal system and ensure that the waste is disposed of properly.
Conduct regular monitoring of the levels of heavy metals in the waste to ensure that they do not exceed the maximum limit set by the Decree of the Minister of Environment KEP-51/MenLH/10/1995.
Implement measures to prevent changes in industrial processes and the use of different raw materials that may affect the levels of heavy metals in the waste.

By implementing these recommendations, the authorities and the industry can ensure that the waste is disposed of properly and that the environment and public health are protected.
