Risk Analysis of SO2 and NO2 Gas Exposure to Transportation Resources to Respiratory Disorders in Street Vendors at the Amplas Integrated Terminal Medan Amplas District, Medan City

The Devastating Impact of Air Pollution on Human Health

Air pollution is a pressing global issue that poses a significant threat to human health. The World Health Organization (WHO) has identified SO2 and NO2 gas as hazardous pollutants that can trigger respiratory disorders. This study aims to analyze the risk of exposure to SO2 and NO2 gas from transportation sources to respiratory disorders in street vendors at the Amplas Integrated Terminal in Medan City.

Methodology and Research Design

This study employed an analytic observational method with a cross-sectional design. The research sample consisted of 70 street vendors at the terminal. Data were analyzed using the Chi-Square test and multiple logistic regression tests with a 95% confidence level. The study aimed to identify the factors that contribute to the risk of respiratory disorders in street vendors due to exposure to SO2 and NO2 gas.

Results and Findings

The results of the study revealed that the concentration of SO2 gas (p = 0.001), exposure time (p = 0.014), and body weight (p = 0.011) had a significant effect on respiratory disorders. In contrast, the concentration of NO2 gas (p = 0.418) and the duration of exposure (p = 1,000) did not show a significant effect. Multiple logistic regression analysis showed that SO2 gas concentration was a dominant factor that affects respiratory disorders, with the highest Exp (B) coefficient value of 297,341.

The Alarming Risk of Respiratory Disorders in Street Vendors

The findings of this study indicate that street vendors at the Amplas Integrated Terminal have a high risk of experiencing respiratory problems due to exposure to SO2 and NO2 gas from vehicles. The length of exposure and weight are factors that worsen this risk. The study highlights the need for immediate action to mitigate the risk of respiratory disorders in street vendors.

Recommendations for Reducing the Risk of Respiratory Disorders

Based on the results of the study, the following recommendations can be made to reduce the risk of respiratory disorders in street vendors:

Medan City Transportation Agency

Making regulations that require vehicle owners to conduct regular emission tests: This measure can help reduce the concentration of SO2 and NO2 gas emitted by vehicles, thereby minimizing the risk of respiratory disorders in street vendors.
Conducting regular inspections of vehicles: This can help identify vehicles that are emitting high levels of SO2 and NO2 gas, allowing for prompt action to be taken to reduce emissions.

Medan City Health Office

Conducting counseling to the community around the terminal, especially street vendors, about the dangers of inhaling SO2 and NO2 gas and ways to reduce their exposure: This can help raise awareness among street vendors about the risks associated with exposure to SO2 and NO2 gas and provide them with information on how to reduce their exposure.
Providing education and training on respiratory health: This can help street vendors understand the importance of respiratory health and how to maintain good respiratory health.

Street Vendors

Equipped with a mask to reduce dangerous gas exposure: This can help street vendors reduce their exposure to SO2 and NO2 gas, thereby minimizing the risk of respiratory disorders.

Conclusion

Increased awareness and comprehensive preventive action are crucial to protect the health of street vendors and the community around the terminal from the risk of respiratory disorders due to air pollution. The recommendations outlined in this study can help reduce the risk of respiratory disorders in street vendors and promote a healthier environment for all.
Frequently Asked Questions (FAQs) about the Risk Analysis of SO2 and NO2 Gas Exposure to Transportation Resources to Respiratory Disorders in Street Vendors at the Amplas Integrated Terminal Medan Amplas District, Medan City

Q: What is the main objective of this study?

A: The main objective of this study is to analyze the risk of exposure to SO2 and NO2 gas from transportation sources to respiratory disorders in street vendors at the Amplas Integrated Terminal in Medan City.

Q: What are SO2 and NO2 gases, and why are they hazardous?

A: SO2 (sulfur dioxide) and NO2 (nitrogen dioxide) are gases that are emitted by vehicles and other sources. They are hazardous because they can trigger respiratory disorders, such as asthma and chronic obstructive pulmonary disease (COPD).

Q: What is the significance of this study?

A: This study is significant because it highlights the risk of respiratory disorders in street vendors due to exposure to SO2 and NO2 gas from transportation sources. It also provides recommendations for reducing this risk.

Q: What are the key findings of this study?

A: The key findings of this study are that the concentration of SO2 gas, exposure time, and body weight have a significant effect on respiratory disorders in street vendors. Additionally, multiple logistic regression analysis showed that SO2 gas concentration is a dominant factor that affects respiratory disorders.

Q: What are the recommendations for reducing the risk of respiratory disorders in street vendors?

A: The recommendations for reducing the risk of respiratory disorders in street vendors include:

Making regulations that require vehicle owners to conduct regular emission tests
Conducting regular inspections of vehicles
Conducting counseling to the community around the terminal, especially street vendors, about the dangers of inhaling SO2 and NO2 gas and ways to reduce their exposure
Providing education and training on respiratory health
Equipping street vendors with masks to reduce dangerous gas exposure

Q: What are the implications of this study for public health?

A: The implications of this study for public health are significant. It highlights the need for increased awareness and comprehensive preventive action to protect the health of street vendors and the community around the terminal from the risk of respiratory disorders due to air pollution.

Q: What are the limitations of this study?

A: The limitations of this study include the small sample size and the cross-sectional design. Future studies should aim to recruit a larger sample size and use a longitudinal design to better understand the relationship between SO2 and NO2 gas exposure and respiratory disorders.

Q: What are the future directions for research on this topic?

A: Future directions for research on this topic include:

Conducting a larger-scale study to confirm the findings of this study
Using a longitudinal design to better understand the relationship between SO2 and NO2 gas exposure and respiratory disorders
Investigating the effects of SO2 and NO2 gas exposure on other health outcomes, such as cardiovascular disease and cancer
Developing and evaluating interventions to reduce the risk of respiratory disorders in street vendors.

Q: What are the policy implications of this study?

A: The policy implications of this study are significant. It highlights the need for policymakers to take action to reduce the risk of respiratory disorders in street vendors due to exposure to SO2 and NO2 gas from transportation sources. This can include implementing regulations that require vehicle owners to conduct regular emission tests, conducting regular inspections of vehicles, and providing education and training on respiratory health.
