There is plenty of evidence showing that air pollution has negative impacts on our health. While lung dysfunction and asthma are probably among the first symptoms people associate with poor air quality, cardiovascular disease, neurodegenerative diseases, and cancer have also been correlated with air pollution.1,2 A new study, published just in time for Clean Air Month, aimed to discover more details on why these correlations exist and what specific particles in the air cause them.
Samples of air obtained from Riverside, California, were analyzed for airborne particulate matter. Metals like nickel, cobalt, and zinc were all detected in the air. The results of the study showed that it takes about three months for the metals initially detected in the air to accumulate within the brain.3 The study also discovered that toxins classified as course airborne particulate matter, specifically nickel, triggered the expression of multiple genes that play a role in inflammation and cancer.3
More research is needed to understand the mechanisms of disease in humans with regard to air pollution. It is also important for future research to study the differences in the components of polluted air in various regions across the country because specific toxins in the air of one city could have distinct impacts on the citizens there compared to a different city. But overall, this study adds to the growing body of research that points to a need for efforts to reduce the amount of toxins in the air, especially in our most polluted cities. Celebrate Clean Air Month by driving less, reducing the energy consumption in your home, or switching to electric gardening tools for the summer. Now would also be a good time to change the air filters in your car, office, and home to keep indoor air clean as well.
