"A new study finds lead from Asia in California air samples, providing evidence that wind can transport airborne pollutants across continents and oceans. This new research is further proof that air pollution is a global issue and needs international cooperation to reduce environmental and health impacts. Approximately one-third of the lead found in the air samples taken from sites in the San Francisco Bay area originated in Asia, but the fraction varied by season and weather patterns. It is likely that other contaminants originating in Asia may reach the U.S. in the same way."
