What You'll Learn
PM2.5 levels are 1.1 times the WHO guideline
Savannah, Georgia, is currently experiencing PM2.5 levels that are 1.1 times the World Health Organization (WHO) annual PM2.5 guideline value. PM2.5 refers to fine particulate matter, tiny particles in the air that reduce visibility and cause a hazy appearance when levels are elevated. These particles can include black carbon, elemental carbon, ultrafine particles, and particles from sand and dust storms.
The WHO has developed global air quality guidelines that provide thresholds and limits for key air pollutants, including PM2.5, that pose health risks. These guidelines are based on a strong body of evidence demonstrating the impact of air pollution on various aspects of health, even at low concentrations. Exposure to air pollution is estimated to cause millions of premature deaths and the loss of healthy years of life worldwide each year.
In the case of Savannah, the elevated PM2.5 levels indicate that the air quality is acceptable for most individuals, but sensitive groups may experience symptoms with long-term exposure. These symptoms can include difficulty breathing and throat irritation. It is recommended that sensitive groups reduce their time spent outside if they experience such symptoms.
To address air pollution and protect public health, the WHO supports countries through evidence-based policies and actions. The organization works in cross-cutting areas such as knowledge, evidence, and measuring progress; institutional capacity building and technical support; and leadership and coordination. By implementing policies that promote cleaner transport, energy-efficient homes, and better municipal waste management, air pollution levels can be reduced, and the health risks associated with air pollutants like PM2.5 can be mitigated.

Air quality is satisfactory
Air quality in Savannah, Georgia, is considered satisfactory, and air pollution poses little to no risk to most individuals. However, it is important to note that sensitive groups, such as people with respiratory conditions, may still experience minor to moderate symptoms with long-term exposure. The air quality index (AQI) in Savannah is currently within the acceptable range, indicating that the air is generally safe for breathing.
While the air quality is deemed satisfactory, there are still some pollutants present in the air. The main pollutant in Savannah's air is PM10, which refers to particulate matter with a diameter of 10 micrometres or less. These tiny particles can include dust, pollen, and mould spores, among other things. While the concentration of PM10 in Savannah's air is below the hazardous level, it can still pose risks to sensitive groups.
Another pollutant that is sometimes present in Savannah's air is PM2.5, which is particulate matter with a diameter of 2.5 micrometres or less. These particles are even smaller than PM10 and can be inhaled deeper into the respiratory system, potentially causing more severe health effects. The concentration of PM2.5 in Savannah's air is currently 1.1 times the World Health Organization's annual guideline value, which is slightly elevated.
It is worth noting that air quality can vary from day to day and even hour to hour, depending on weather conditions, industrial activity, and other factors. Therefore, it is always a good idea to check the real-time air quality index before planning outdoor activities, especially for sensitive individuals. There are several online tools and mobile applications that provide up-to-date air quality data for Savannah and other cities, which can be helpful in planning activities and protecting your health.
Overall, while the air quality in Savannah, Georgia, is currently satisfactory, it is important to stay informed about any changes in air pollution levels, especially if you are part of a sensitive group. By staying aware and taking appropriate precautions, you can ensure that you breathe safe and healthy air, regardless of the air quality conditions. Checking air quality forecasts and monitoring your own health responses to different pollution levels can help you make informed decisions about your outdoor activities.

Sensitive groups may experience symptoms
Savannah, Georgia, has a reported air quality index (AQI) of 107, which is considered "unhealthy for sensitive groups". The main pollutant is PM10, with a concentration of 168 µg/m³. PM2.5 concentrations are also 1.1 times the World Health Organization's annual guideline value.
Children are at an increased risk from air pollution primarily because they spend prolonged periods outdoors, often playing sports or games. Evidence indicates that long-term exposure can affect lung function growth. Similarly, older adults are considered a sensitive group as they may experience more serious effects from particle pollution. This is especially true for those with pre-existing respiratory or heart conditions, who may not be able to breathe as deeply and may experience coughing, chest discomfort, and wheezing, and unusual fatigue.
People with diabetes are also considered a sensitive group and may be more susceptible to the health effects of air pollution. While the specific mechanisms are still being studied, it is thought that air pollution may impact glucose metabolism and insulin resistance, potentially exacerbating existing diabetes-related issues.
Overall, it is important for individuals in sensitive groups to be aware of air quality alerts and take appropriate precautions to reduce their exposure to air pollution when necessary.

Main pollutant is PM10
The air quality in Savannah, Georgia, is generally acceptable for most individuals. However, the main pollutant, PM10, can cause issues for sensitive groups. PM10 refers to inhalable particles with diameters of 10 micrometres or less. These particles are small enough to be inhaled and can deposit on the surfaces of the larger airways in the upper region of the lung. This can lead to adverse health effects, particularly for those with pre-existing respiratory conditions.
PM10 is composed of a complex mixture of solids and aerosols, including dry solid fragments and solid cores with liquid coatings. These particles can be made up of inorganic ions, metallic compounds, elemental carbon, and organic compounds. Sources of PM10 include emissions from the combustion of gasoline, oil, diesel fuel, and wood. Additionally, construction sites, landfills, agriculture, wildfires, and industrial processes also contribute to PM10 pollution.
The presence of PM10 in the air can have significant health impacts. Short-term exposure has been linked to a worsening of respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD). Individuals with these conditions may experience symptoms such as difficulty breathing or throat irritation. In some cases, they may need to reduce their time spent outdoors or limit physical activities to minimise their exposure to PM10.
While the long-term effects of PM10 exposure are less clear, several studies suggest a potential link between prolonged exposure and respiratory mortality. The small size of PM10 particles allows them to be inhaled and deposited in the upper region of the lungs, which can induce tissue damage and lung inflammation over time. Therefore, it is important for individuals in Savannah, Georgia, particularly those with respiratory conditions, to be aware of the PM10 levels and take necessary precautions to protect their health when pollutant levels are high.
