Objective: Exploring the relationship between PM10 intra- and extra-domiciliary levels and the lung function of people living in La Sierra, Antioquia, Colombia.
Materials And Methods: A survey and field observations were used for determining the environmental conditions and the immediate household environment of 124 people who had taken a spirometric test. Meteorological conditions were monitored: temperature, relative humidity, rainfall, wind speed and PM10 (24 hours) within and outside the houses.
Results: Indoor PM10 (0.05 mg/m3) in 50 % of the houses was
Discussion: The results suggested that indoor pollution came from automobile emission, industrial combustionand unpaved roads (i.e. producing a lot of dust). PM10 decreased with increasing rain fall, higher relative humidity and increased wind speed.

Precise estimates of vehicular emissions at fine spatial scales are essential for effective emission reduction strategies. Achieving high-resolution vehicular emission inventories necessitates detailed data on traffic flow, driving patterns, and vehicle speeds for each road network segment. However, in developing countries, the lack of comprehensive traffic data, limited infrastructure, and insufficient monitoring systems constrains the development of high-resolution inventories.

Background: Accurate estimates of personal exposure to ambient air pollution are difficult to obtain and epidemiological studies generally rely on residence-based estimates, averaged spatially and temporally, derived from monitoring networks or models. Few epidemiological studies have compared the associated health effects of personal exposure and residence-based estimates.
Objective: To evaluate the association between exposure to air pollution and cognitive function using exposure estimates taking mobility and location into account.
Using low-cost sensors to assess common air pollution sources across multiple residences.

The rapid development of low-cost sensors provides the opportunity to greatly advance the scope and extent of monitoring of indoor air pollution. In this study, calibrated particle matter (PM) sensors and a non-negative matrix factorisation (NMF) source apportionment technique are used to investigate PM concentrations and source contributions across three households in an urban residential area. The NMF is applied to combined data from all houses to generate source profiles that can be used to understand how PM source characteristics are similar or differ between different households in the same urban area.
