Table 7 Relationships between elevated exposure to particulate matter (PM) and asthma and Early Airways Obstruction in the stable and granary in the farmers

From: Indoor exposure to particulate matter and volatile organic compounds in dwellings and workplaces and respiratory health in French farmers
