Air Pollutants and Kids' Focus: What a Big Study Found

July 4, 2026

Scientists looked at over 130, 000 school kids in southern China to see if tiny bits of certain chemicals in the air could affect how well they pay attention. These chemicals, called organophosphate esters or OPEs, often stick to dust and pollution floating in the air. Most of them come from things

Air Pollution's Impact on Athletes' Health

May 29, 2025

The air we breathe can have a big impact on our health, especially for athletes who train outdoors. One major concern is particulate matter 2. 5, or PM2. 5. These tiny particles can easily enter the lungs and cause problems. Athletes who exercise in polluted areas might be at a higher risk. A recent

Fairbanks' Air Quality: A Winter Challenge

March 6, 2025

Fairbanks, Alaska, faces a significant issue with fine particulate matter, known as PM2. 5. This tiny pollution is a big problem, especially in winter. The air quality standards set by the National Ambient Air Quality Standard (NAAQS) are often exceeded in Fairbanks. The standard for PM2. 5 is 35 mi

Uncovering the Causes of City Smog: A Machine Learning Approach

December 3, 2024

Air pollution, specifically fine particulate matter (PM2. 5), is a big problem in many Chinese cities. To tackle this, researchers used a machine-learning model that combines CatBoost and Tree-Structured Parzen Estimator (TPE) to study PM2. 5 levels in 297 cities from 2000 to 2021. They found that s
