LOW-COST SUSPENDED PARTICULATE MATTER SENSORS: INTEGRATION INTO AIR QUALITY MONITORING
Advances in knowledge about the health effects of atmospheric particles, as well as their influence on climate and climate change, have led to the demand for monitoring their levels in ambient air and the reliable determination of ambient concentrations at surface level, carried out in most countries with reference instruments. However, the cost and resources required for the acquisition and operation of these reference instruments hinder the installation of air quality monitoring networks. In recent decades, there has been a great deal of international development of air pollutant sensors that, although not regulatory, are portable, lower cost and relatively easier to operate than reference instruments. Advances in microprocessors and miniaturization have allowed the introduction of these sensors, facilitating an unprecedented increase in their use for non-regulatory air quality assessment purposes. Although the use of low-cost sensors in personal and public health care is accepted, the concern arises when the data obtained are used as substitutes or complements to reference networks for air quality monitoring. The purpose of this article is to contribute to the regional discussion of guiding criteria for the use of low-cost atmospheric particulate sensors. The work is based on the review of about fifty scientific articles published in the last decade.
