Air quality in Mostaganem right now
Right now the modelled US Air Quality Index for Mostaganem, Algeria is 38, which falls in the "Good" band (up to 50). Air quality is satisfactory and poses little or no risk; a good time for outdoor activity.
The index is driven mainly by PM2.5, whose own sub-index is 38. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 8.5 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 14 µg/m³ against a guideline of 45; ozone is 66 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 13 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 166 µg/m³.
NASA FIRMS shows 43 fire hotspots within 300 km in the last day (nearest about 29 km), but particle levels are not elevated enough to point to smoke right now.
