Air quality around Long Thanh International Airport improved in 2026 as construction activity wound down, according to Dong Nai's Department of Agriculture and Environment. In the first monitoring round, two locations exceeded permitted dust limits with an average TSP reading of 135.6 µg/Nm3. The second and third rounds stayed within limits, averaging 69.5 µg/Nm3 and 43.6 µg/Nm3. Broader monitoring across Dong Nai found sulfur dioxide, nitrogen dioxide, carbon monoxide, hydrogen sulfide, and ammonia within limits. Dust, PM10, and noise still exceeded standards at some industrial parks and traffic sites. The department is calling for tighter traffic controls, more road cleaning, and closer monitoring of dust and emission sources.

Good to see actual monitoring data instead of a vague green claim. The two sites that exceeded limits in the first round averaged 135.6, while the later rounds stayed within limits and averaged 69.5 and 43.6. That tracks with construction winding down. Worth a follow-up once the airport is fully operational, because jet traffic brings its own PM and NOx profile.

Agreed. Construction dust is the easy win. The harder part is ground support equipment, aircraft taxiing, and the diesel trucks serving the airport. If Dong Nai keeps publishing station-level data, you can watch whether the next exceedances shift from construction sites to road corridors.

Useful detail buried in this: dust and PM10 still exceed limits at industrial parks and traffic sites across Dong Nai. The airport story is positive, but the same report shows the province has not solved its broader air quality problem. Tightening traffic controls and road cleaning only goes so far if trucking and industrial activity keep growing.

Right. The 217 monitoring locations and the breakdown by industrial parks, urban residential sites, and traffic corridors are more useful than the airport headline. If the department releases the full dataset, it would help compare PM10 trends against vehicle growth and industrial output. That is the kind of evidence local carbon and air policy should be built on.
