Air pollution by carbon monoxide can be possibly related to the increase in arterial blood pressure and the risk of arterial hypertension. The study was made in Kaunas. The concentration of daily carbon monoxide was estimated according to the data provided by the Department of Environment of Kaunas and environmental monitoring stations of Kaunas city municipality. The study aims to determine a short-term impact of air pollution by carbon monoxide on the number of calls for ambulance due to the risk of arterial hypertension. The following factors were taken into consideration during the study: the time of calling for ambulance, seasons, weekdays and air temperature. Almost half of calls for ambulance (45.1%) due to the increase in arterial blood pressure were recorded in the afternoon (from 0 to 15 calls a day). The number of calls for ambulance due to the increase in arterial blood pressure was the lowest in the warmest time of the year (summer) regardless of the time of the day, and the highest in winter (in the afternoon and evening). The number of calls for ambulance at night due to the increase in arterial blood pressure was significantly higher on Mondays and Tuesdays. The number of calls for ambulance was 14% lower in the afternoon when the air temperature was 10 oC and 13% lower in the evening and at night. The number of calls for ambulance due to the increase in arterial blood pressure can be related to increased concentration of carbon monoxide one day before the call for ambulance (as a result of increased concentration of carbon monoxide by 1 mg/m3, the risk increases by 1.24 times). Increased concentration of carbon monoxide did not have negative influence on the number of calls for ambulance. Negative effect of carbon monoxide was observed when daily carbon concentration exceeded 80th percentile (0.583 mg/m3). Oro tarša anglies monoksidu, tikėtina, susijusi su arterinio kraujo spaudimo padidėjimu bei arterinės hipertenzijos išsivystymo rizika. Tyrimas atliktas Kaune, paros anglies monoksido koncentracija vertinta pagal Kauno regiono aplinkos apsaugos departamento ir miesto savivaldybės ekologinio monitoringo stotyse išmatuotus duomenis. Tyrimo tikslas – nustatyti trumpalaikį oro taršos anglies monoksidu poveikį greitosios medicinos pagalbos iškvietimų dėl arterinės hipertenzijos rizikai, atsižvelgiant į iškvietimo laiką ir kontroliuojant sezoniškumo, savaitės dienos bei oro temperatūros įtaką. Beveik pusė iškvietimų (45,1 %) dėl arterinio kraujo spaudimo padidėjimo buvo registruojami popietinėmis valandomis (nuo 0 iki 15 iškvietimų per parą). Šilčiausiu metų laiku (vasarą) iškvietimų skaičius dėl arterinio kraujospūdžio padidėjimo nepriklausomai nuo paros meto buvo mažiausias, o didžiausias – žiemą (po pietų ir vakare). Nakties metu iškvietimų rizika dėl padidėjusio arterinio kraujo spaudimo buvo žymiai didesnė pirmadieniais ir antradieniais. Iškvietimo parą oro temperatūrai pakilus 10 ºC greitosios medicinos pagalbos iškvietimų rizika buvo 14 % mažesnė popietinėmis valandomis bei 13 % mažesnė vakare ir naktį. Iškvietimų dėl padidėjusio arterinio kraujospūdžio ryte rizika sietina su padidėjusia anglies monoksido koncentracija parą prieš iškvietimą (padidėjus anglies monoksido koncentracijai 1 mg/m3, rizika padidėja 1,24 karto). Padidėjusi anglies monoksido koncentracija neigiamos įtakos iškvietimams neturėjo. Neigiamas anglies monoksido poveikis stebėtas paros koncentracijai viršijus 80 procentilių (0,583 mg/m3).

Abstract BackgroundShort-term variations in particulate matter (PM) and traffic-related air pollutants (e.g., nitrogen dioxide, NO2) have been associated with daily mortality and cardiovascular health outcomes in previous studies. We aimed to evaluate whether short-term changes in PM in three size fractions (PM2.5 , PM2.5-10 , and PM10) and NO2 were associated with systolic and diastolic arterial blood pressure (SBP and DBP, respectively) in the Women’s Health Initiative Observational Study (OS) and Clinical Trials (CT). MethodsWe used linear mixed-effect models to estimate the association between short-term air pollution concentrations and repeated measures of arterial blood pressure. ResultsWe found statistically significant positive associations between short-term measures (lag days 3-5) of PM2.5 as well as NO2 for both SBP and DBP in fully adjusted models when not controlling for calendar time. Also, in only the CT, PM10 and PM2.5-10 were associated with DBP but not SBP. In fully adjusted models controlling for calendar time, associations with PM2.5-10 and NO2 remained statistically significant for DBP (except for PM2.5-10 in the OS). Specifically, in the CT group, each IQR increase in lag 3-5 NO2 exposure (9.88 ppb) was associated with a 0.13 mm Hg increase in DBP. Also, each IQR increase in lag 3-5 PM2.5-10 exposure (8.46 µg m -3) was associated with a 0.05 mm Hg increase in DBP. Effect modification was found for body mass index (BMI), socioeconomic position (SEP), diabetes, dietary sodium intake, combined fruit and vegetable consumption, and long-term PM2.5 for PM2.5 , PM10 , and NO2 . Shorter lag periods (lag 0 through lag 2) typically exhibited lesser and, especially for SBP, sometimes negative associations. In two-pollutant models of exposures lagged over 3-5 days, NO2 associations with DBP were stronger (0.20 mm Hg per IQR), but those for PM2.5-10 were attenuated to null, as compared to single-pollutant models. ConclusionsOur findings are consistent with short-term (lag days 3-5) PM2.5-10 and NO2 levels as risk factors for acute cardiovascular outcomes and cardiovascular disease, though two-pollutant model results suggest NO2 is more likely responsible for the observed effects.
