In recent years, the impact of unseen airborne particles on human health has become increasingly apparent. This is especially true for those with seasonal allergies, who are particularly vulnerable to tree pollen and other allergens in the air. While there is plenty of information available on pollen counts and allergy indices, there is limited information on cancer-causing trace elements like lead and arsenic in urban areas of developing countries.
A team of researchers led by Randall Martin at Washington University in St. Louis set out to analyze global ambient particulate matter (PM) and understand its components, including mineral dust and trace element oxides. These trace elements are known for their negative health effects and are mainly emitted through human activities such as fossil fuel combustion and industrial processes.
To conduct their research, they used data from the Surface Particulate Matter Network (SPARTAN), which measures PM elemental composition worldwide. Their study found that American, Indian, and Vietnamese regions had elevated levels of these harmful trace elements. This prompted the researchers to recommend interventions to reduce emissions from human activities in these areas.
Their findings were recently published in ES&T Air on March 10th and could pave the way for future efforts to improve air quality in developing countries. For more information about this study and how it could benefit your health, visit the McKelvey Engineering website today.
