Key findings
Each 10 μg/m³ same-day PM10 was linked to a 0.85% rise in all-cause admissions; lag-1 ozone raised cardiovascular admissions 2.91% per 10 ppb. On 63 dust-storm days, all-cause admissions were 4.8% higher. Respiratory admissions showed no overall PM10 association.
Methodology
Authors ran a 10-year (1995–2004) time-series of daily hospital admissions in Nicosia against urban PM10 and ozone, separating non-storm days from meteorologically confirmed dust-storm days and checking rural-monitor and co-pollutant models.
Limitations
Dust-storm inference is limited by only 63 event days; the study cannot separate particle composition from mass, and it does not measure individual-level exposure or mortality.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
This library holds 9 empirical papers on air pollution with measured outcomes rather than reviews.
Evidence for the claim as stated.
Same-day PM10 and lagged ozone increase hospital admissions in Nicosia, and dust-storm days add extra cardiovascular risk.
Evidence for the claim as stated.
Associations from one city or one pollutant are not a universal dose–response, and traffic proximity is not the same as a measured concentration.

A 10-year (1995–2004) Nicosia series linked daily hospital admissions to urban PM₁₀ and ozone, separating meteorologically confirmed dust-storm days. Each 10 μg/m³ same-day PM₁₀ was linked to a 0.85% rise in all-cause admissions; lag-1 ozone raised cardiovascular admissions 2.91% per 10 ppb. On 63 dust-storm days, all-cause admissions were 4.8% higher. Respiratory admissions showed no overall PM₁₀ association.
Evidence for the claim as stated.
City hospital series do not agree on which pollutant or lag carries the acute signal. Nicosia finds same-day PM₁₀ for all-cause admissions (0.85% per 10 μg/m³) and lag-1 ozone for cardiovascular admissions (2.91% per 10 ppb) but no overall PM₁₀–respiratory link. Canadian EDs find CO/NO₂ most consistent for cardiac diagnoses and ozone for asthma/COPD, with 3-hour averages null and Edmonton dominating the sample. Medicare finds PM₂.₅ mass plus composition for CVD, MI and respiratory admissions among those 65+. Treating 'time series show pollution raises admissions' as one coefficient hides those splits.
Evidence for the claim as stated.
The 2018 forest-wilting paper is an NDVI/climate time series, not a health Poisson model. Early wilting of 10.8% of forest and a spring-2019 NDVI gap of +0.015 answer a drought-impact question. That is a real disagreement of scientific target under the same method heading, not a second admissions estimate.
