The Importance of Air Quality Measurement

Air is the most essential component after water in supporting life on earth. In addition to providing oxygen, air also functions as a conductor of sound, cooling hot objects, and acts as a medium for the spread of disease among living things. Unfortunately, air quality is never really clean from pollutants, which can cause various health problems, such as damage to the respiratory tract of humans, animals, and plants. Therefore, the measurement of ambient air quality standards is very important to ensure that the levels of substances, energy, and other components in the air remain within safe limits. Nitrogen dioxide (NO2) is one of the pollutants that need to be monitored closely, as it can have a negative impact on health.

Nitrogen dioxide is a colorless and odorless gas that is usually produced from human activity, such as motor vehicles and industry. It can cause irritation to the respiratory tract, worsen asthma conditions, and increase the risk of respiratory tract infections. In addition, NO2 can also contribute to the formation of ozone on land surface and other dangerous pollutants. The measurement of NO2 levels in ambient air is crucial to ensure that the air quality remains within safe limits and to prevent the negative impacts of NO2 on human health and the environment.

The Griess Saltzman Method: A Reliable Technique for NO2 Analysis

The Griess Saltzman method is one of the common techniques used to analyze NO2 levels in the air. This method involves the NO2 reaction with Griess's reagent, which produces a certain color. The resulting color intensity is measured using a spectrophotometer, which is able to provide accurate data about the NO2 concentration in air samples. With the selected wavelength (550 nm), this method has a high sensitivity for NO2 detection. The Griess Saltzman method is a reliable technique for NO2 analysis, as it provides accurate and reliable results.

The Importance of NO2 Analysis in Ambient Air

The analysis of NO2 levels in ambient air is essential to ensure that the air quality remains within safe limits. NO2 is a pollutant that can have a negative impact on human health and the environment. The measurement of NO2 levels in ambient air can help to identify areas where air pollution is a problem and to develop strategies to reduce NO2 emissions. The results of NO2 analysis can be used to develop policies and regulations to control air pollution and to protect human health and the environment.

The Results of NO2 Analysis Using the Griess Saltzman Method

The results of the analysis showed that the NO2 concentration reached 1.81 μg/nm³. This figure refers to the regulations determined by the Government Regulation of the Republic of Indonesia Number 41 of 1999 concerning Control of Air Pollution, where the level is declared safe and meets health standards for humans and the environment. The results of the analysis showed that the NO2 level was within safe limits, which emphasized that although air pollution was a serious problem, ambient air quality in the area under study was still within safe limits.

Conclusion

The measurement of NO2 levels in ambient air is crucial to ensure that the air quality remains within safe limits and to prevent the negative impacts of NO2 on human health and the environment. The Griess Saltzman method is a reliable technique for NO2 analysis, as it provides accurate and reliable results. The results of NO2 analysis can be used to develop policies and regulations to control air pollution and to protect human health and the environment. Through a better understanding of pollutants such as NO2, as well as using the right analysis method, it is expected that air pollution can be controlled effectively in order to create a healthier environment.

Recommendations

Based on the results of the analysis, the following recommendations can be made:

The government and the community must continue to strive to maintain and improve air quality so that human health and the environment are maintained.
