Summary:
The object of this PhD thesis is to investigate the effect of bioclimatic
conditions and air pollution on cardiovascular and respiratory diseases of
residents on the island of Crete. Initially, an attempt is made to evaluate and
analyze bio-climatic conditions of the island using thermal indices (PET and
UTCI) based on the humans’ energy balance. As far as particulate matter and
Saharan dust episodes are concerned, they were recorded by passive samplers and
in the process, the concentrations (mg/m3) of total and anthropogenic particles
with geometric diameters between 2.5mm and 80mm, were estimated using an
automated optical microscope methodology, depicting the largest concentrations
in Heraklion city, during episodes of Saharan dust transport. Furthermore, the
mineral composition of Saharan dust was examined, by scanning electron
microscopy (SEM), indicating the harmful minerals to human health. Besides,,
the relationships between bioclimatic conditions and cardiovascular and
respiratory problems in Heraklion city were carried out, showing a significant
correlation between cold and the increased frequency of daily hospital
admissions and particularly the respiratory problems were intensified during
spring period, which is associated with the appearance of Saharan dust episodes
and Fohn winds, acting synergistically exacerbating the bioclimatic conditions
The impact of meteorological-biometeorological parameters and air pollution on
cardiovascular and respiratory problems for residents of Heraklion city were
evaluated qualitatively and quantitatively, using generalized additive models
(GAM), indicating an increase in daily hospital cardiovascular and respiratory
admissions by 1.8% and 4% respectively, with the decrease of temperature,
radiant temperature (Tmrt) and bioclimatic indices and the increase of
cloudiness. The relative humidity does not appear to affect the cardiovascular
and respiratory admissions. Moreover, the increase in particle size from 2.5μm
to 10μm lead to increased admissions of 10%. for cardiovascular and 6.5% for
respiratory admissions, on average. Finally, the generalized linear models
(GLM), which emerged between the medical and climatological data, were applied
in the future bioclimatic conditions (simulations of regional climate model
RAMKO (KNMI) for SRES A1B) in order to assess the admissions in near future
(2021-2050) and far future(2071-2100).
