Air pollution exposure associated with increased risk of irregular heartbeat: Large study

A large Chinese study found that acute air pollution exposure is associated with an increased risk of arrhythmia, with the strongest link seen in atrial flutter and supraventricular tachycardia. Exposure to pollutants like nitrogen dioxide was found to persist for up to 24 hours after initial exposure.

New insights on why improvements to Chesapeake Bay remain a challenge

A new study on Chesapeake Bay water quality found that pollution thresholds affect reduction efforts, and larger reductions may be needed to induce complete reversal of eutrophication-induced hypoxia. The research revealed that the system responds only until a certain threshold is crossed, then it takes twice the effort to make a change.
