The results of a study investigating factors of air pollution in residential areas was published in the journal PLOS ONE.
Researchers from the University of San Diego for three months followed by air quality in the homes for almost 300 families. All these families had at least one child under the age of 14 and at least one family member smoked in the house. In each case, the researchers found the monitors that keep track of the contents of microparticles in the atmosphere in two places at home where often smoke, and in the nursery.
The device continuously scans the air for levels of particle size from 0.5 to 2.5 micrometers in diameter. These dimensions correspond roughly to the dust particles, fungal spores, car exhaust, and by-products of combustion. Particles of this size are particularly dangerous to health, primarily for children, as they are able to penetrate deep into the lungs, causing various respiratory and cardiovascular diseases.
In addition to gathering information about the level of air pollution in homes, the researchers regularly surveyed their residents about what they are doing at different points — cooking, cleaning, Smoking and so on. Three months later, the scientists compared all of the collected data and got the full picture.
As expected, in the first place on volume of harmful particulates entering the atmosphere of the home, was Smoking. In houses where their occupants smoked indoors, the levels of such substances in the air is twice higher than where the house is not smoked. Surprisingly, Smoking marijuana pollutes the atmosphere in the room is slightly less than tobacco Smoking. Rich sources of dangerous particles in your home air are also non-Smoking scented candles and incense, cooking oil and spraying chemical products.
The researchers plan to continue studying this topic, in particular they are going to find out how air pollution indoors while Smoking marijuana affects those who do not smoke.
