Persistent organic pollutants are chemicals of substantial international concern. MIT researchers have built a model to simulate long-range atmospheric transport of polycyclic aromatic hydrocarbons (PAHs).
The hybrids were part of UPS’ first cohort of 50 (prototype) hybrid electric vans. Using a t-test, researchers found neither difference to be statistically significant.
