Indoor Air Quality
Protecting children from the environment: More than 1 in 4 deaths of children under 5 years of age are attributable to unhealthy environments. Every year, environmental risks – such as indoor and outdoor air pollution, second-hand smoke, unsafe water, lack of sanitation, and inadequate hygiene – take the lives of 1.7 million children under 5 years, say two new WHO reports.
Indoor Air Quality - Sources of air pollutants. Indoor air pollutants can be categorised into two main groups: biological and chemical. Symptoms of health problems caused by biological pollutants include: sneezing; itchy watery eyes, coughing, shortness of breath, dizziness, redness, fever and digestive problems. Chemical pollutants, depending on the type of the pollutant, have the potential to cause respiratory infections and damage and irritation to the lungs.
