Pollution from the Tijuana river affects air quality in San Diego, finds study

Summary

91% Informative

A new study from the University of California San Diego examines how pollutants in wastewater travel and are transmitted in the atmosphere through coastal aerosols.

Researchers found a mixture of illicit drugs, drug metabolites, and chemicals from tires and personal care products aerosolize from wastewater.

The study looked at two aspects of wastewater pollution: the source and the concentration of pollutants along the San Diego County coastline.

An estimated 80% of all global wastewater is untreated.

Of the portion that is treated, many plants remove bacteria, but not chemical pollutants.

These chemicals remain in the water, which is released into rivers, lakes and oceans.

Aerosolization of this polluted water exposes billions of people through airborne transmission.
