Study in state capital proves that professionals who work daily in traffic, exposed to pollution from the streets, are more subject to disease than those who work in less polluted areas

The professionals who work every day in traffic, exposed to pollution from the streets, are more subject to disease than those who work in less polluted areas. The conclusion is a study in São Paulo, by researchers from the University Federal de São Paulo (Unifesp), USP and Harvard (USA).

The researchers followed groups highly vulnerable to pollutant gases expelled by vehicles: 71 taxi drivers and 30 staff CET (Traffic Engineering Company), which are responsible for monitoring the traffic. For comparison, a group was considered less vulnerable, 20 employees of the Garden Forest, located in the Sierra Cantareira capital region with the lowest level of pollution.

After four years of research, scientists have concluded that the group exposed to traffic pollution suffered various types of damage in the body. The research involved 90 scientists from specialties such as ophthalmology, medical clinic, cardiology, pulmonology, pathology and even mathematics.

Scientists have concluded that the group exposed to traffic pollution of various kinds suffered damage in the body.

Lead researcher, Professor Paul Saldiva, Department of Pathology, School of Medicine, USP, said in an interview with Brazil Agency, the polluted air caused inflammation in the eyes and lungs, changes in blood pressure and heart rhythm disorder procoagulant, more prone to obesity, conjunctivitis, rhinitis and more chromosomal breaks, which means more risk of cancer, both in the mucosa exposed, as in circulating cells, said.

Besides USP professor, Saldiva a member of the Scientific Committee of Harvard University and was a member of the Committee of the World Health Organization (WHO) has defined standards for air quality. He noted that in addition to increased risk of diseases, taxi drivers and traffic controllers had adaptive actions, ie, when the body needs to adapt and work within the limits due to noise and stress situations, common to large urban centers. For example, the blood pressure control, the system inhibits us to increase the maximum pressure is connected explained.

The study also assessed changes in health status within the group most exposed to pollution. It was proven that the extent to which pollutants increases, also worsening the body.

The findings were presented today (23), in São Paulo, during the Scientific Seminar of Environmental Pollution. According Saldiva, studies are not yet completed and the presentation today brought an overview of the results. Scientists still formulate a report that will be forwarded to the National Council for Scientific and Technological Development (CNPq), which funded the research.
