Effects of diesel exhaust and it′s particles on respiratory and reproductive Systems in mice

In recent year, there has been a progressive increase in urban air pollution that is Characterized by high concentrations of atmospheric particulate matter (PM10), resulting primarily from increase of automobils, especially diesel engine powered cars. Although the mechanisms of underling respiratory morbidity due to PM10 are not nuclear, it is thought that the fine particles (PM2.5) are of gratest concern to health since they can be breathed most deeply into the lung, where they are likely to be more toxic than the larger particles.(omitted)
