Investigation of the possible link between exposure to air pollution and changes in blood coagulation parameters

This study investigated the hypothesised relationship between variations in exposure to airborne pollution and changes in blood coagulation factors, as a causal factor in cardiovascular disease. The study was performed using two standard coagulation test results, compared to air pollution data, in the time period July 1996 to July 1997. Five air pollutants, PM₁₀, NO(x), SO₂, CO, and O₃ were correlated and compared with blood coagulation test results, to look for associations between exposure to air pollution and changes in blood coagulation factors. The study established that exposure to varying concentrations of air pollutants did not affect the blood coagulation times in the study group.
