Local Environmental Conditions
Coronel Fabriciano anchors the Minas Gerais Doce River valley steel district, where native Atlantic Forest remnants, eucalyptus, and the Doce River corridor vegetation are the main pollen sources in this Usiminas industrial zone. The tropical climate supports year-round pollen production, while the river valley concentrates pollen under calm conditions and the wet summer months bring the most frequent rainfall interruptions throughout this Minas Gerais steel valley industrial city.
Coronel Fabriciano's pollen season concentrates during the dry season, when eucalyptus and the Doce River corridor vegetation pollen disperses most readily across the area; the wet season brings frequent rainfall that interrupts counts for the rest of the year.

Does pollen in Coronel Fabriciano come from nearby or far away?
Studies show that most pollen exposure (often 70–90%) comes from nearby sources, such as local trees and vegetation. A good pollen forecast therefore depends on accurately representing local vegetation. Pollen can travel long distances, but this usually matters only early in the season or during specific wind events.
Are pollen levels in Coronel Fabriciano based on measurements or forecasts?
Pollen data is often misunderstood. Most "pollen levels" are not real-time measurements, but forecasts.
Direct pollen measurements are typically delayed by 1-2 days because they require manual analysis. To show current conditions in Coronel Fabriciano, modern forecasts combine recent measurements, weather data, and information about local vegetation.
This allows us to estimate pollen levels for today and the coming days, not just report the past.

Understanding the Scale
The 0–100 scores represent risk levels, not direct measurements of pollen or air pollutant concentrations. Higher scores indicate higher risk. Pollen and air quality use different thresholds.
Pollen
| None | 0 | No or negligible risk of exposure. Pollen/mold exposure is expected to be minimal. |
| Low | 0-25 | Low risk of exposure. Small amounts of pollen or mold spores may be present. |
| Moderate | 25-50 | Moderate risk of exposure. Pollen/mold exposure is expected to be noticeable. |
| High | 50-75 | High risk of exposure. Elevated pollen/mold exposure is expected. |
| Very High | 75-100 | Very high risk of exposure. Pollen/mold exposure is expected to be at or near its highest levels. |
