SUMMARY -Th e aim of the study was to investigate the unknown eff ect of air pollutants on the occurrence or deterioration of respiratory diseases in the area with a humid continental climate. Th is retrospective study included 5868 patients with respiratory symptomatology (upper respiratory tract infection (URTI), pneumonia, acute bronchitis, chronic obstructive pulmonary disease (COPD), and asthma) admitted to emergency department (ED). Th e number of patients, values of meteorological parameters (mean daily values of air temperature pressure and relative humidity) and concentrations of air pollution particles (≤10 μm (PM 10 ), ozone (O 3 ) and nitrogen dioxide (NO 2 )) were collected during a two-year ( July 2008 -June 2010) period. Th ere were 1839 (31.3%), 1712 (29.2%), 1313 (22.4%), 614 (10.5%) and 390 (6.6%) patients with pneumonia, COPD, URTI, acute bronchitis and asthma, respectively. Th e mean daily concentrations of NO 2 (25.9 (1.7-89.7) μg/m 3 ) , O 3 (47.1 (4.7-135.4) μg/ m 3 ) and PM 10 particles (25.7 (4.6-146.6) μg/m 3 ) were below the legally defi ned thresholds. Among other results, the occurrence of respiratory diseases showed positive Spearman's correlation with the values of air humidity (days 0-3, r=0.15 to 0.19), PM 10 (days 0-3, r=0.10 to 0.13) and NO 2 concentrations (day 0, r=0.11), and negative correlation with the values of air temperature (days 0-3, r=-0.36 to -0.34), pressure (day 0, r=-0.10) and O 3 concentrations (days 0-3, r=-0.21 to -0.22) (p<0.05 all). In conclusion, the occurrence of respiratory diseases showed correlation with weather conditions and air pollutants despite the legally permitted values in the region with a humid continental climate.

“…We have found a remarkable link between the anticyclonic component situations and high concentrations of contaminants, in conjunction with a high RAI in winter. In fact, several studies have evaluated associations between air pollution and hospital visits for respiratory diseases (Stieb et al 2009): concentration of CO exhibited a correlation with upper respiratory infection (Peel et al, 2005), concentration of NO 2 with asthma (Erbas et al, 2005), concentration of particulate matter with pneumonia (Peel et al, 2005), concentration of SO 2 with asthma (Wilson et al, 2005) and concentration of O 3 with asthma too (Jaffe et al, 2003).…”

This study considers the relationship between the risk of hospital admission due to respiratory diseases, the daily weather, and the air pollution conditions between 2000 and 2006. A synoptic climatological approach is used to investigate the links between weather types and all hospital admissions due to respiratory diseases in Castilla-La Mancha (CLM), Spain. The main circulation weather types (CWTs) were determined for winter and spring, the seasons with the highest percentage of hospital admissions, and the frequency distribution of these types was also analyzed. The study includes a summary of the main characteristics of the hospital admission series and their distribution over the study period of seven years, as well as the frequency distributions of the admissions classified by gender and age, for each season, month and day of the week. In addition, an admission index was used to compare CWTs and hospital admissions due to respiratory diseases. The results show distinctly different responses of daily respiratory disease admission rates (RD) to the eight CWTs identified in winter and in spring. In winter, three CWTs (southwesterly (SW), anticyclonic (A) and hybrid anticyclonic southwesterly (HASW)) present values 1.5 times above the average admission rates. In contrast, there are no significant differences in spring. Finally, the results of Principal Component Analysis applied to the daily series of meteorological parameters, atmospheric pollutants and morbidity data revealed that in winter the decrease in RD is related to increases in temperature and pressure. These results represent an important step in identifying reliable connections between weather-air pollutants and human health.

“…[31][32][33] Visits to the emergency department for pulmonary complaints have been shown to increase during periods of severe air pollution. 34 One possible explanation is DEPs combining with atmospheric allergenic molecules to create even more inflammatory allergens. 35 Admission rates for pediatric asthma exacerbation have been shown to be higher in areas with greater-than-average diesel emissions.…”

Diesel fuel and the products of its combustion represent one of the toxins most commonly encountered by people living in both urban and rural areas of the world. As nations become more heavily populated, there will be increasing reliance on diesel fuel to power mass transportation and commercial vehicles, as well as heavy machinery involved in construction, farming, and mining. The majority of patients who present to urban primary care clinics and emergency departments will have had significant chronic exposure to diesel exhaust because most use and/or live near busy streets and highways.
