Inhalation of atmospheric polycyclic aromatic hydrocarbons (PAHs) bound to particulate matter can have adverse effects on human health. Particle size plays an important role in assessing health ...risks. The aim of this study was to compare concentrations of PAHs in different particle fractions. Measurements of PAHs were carried out in Zagreb, the capital of Croatia (~ 790,000 inhabitants). The measuring station was located in the northern, residential part of Zagreb, close to a street with modest traffic density. Twenty-four-hour samples of PM

, PM
2.5
and PM

and PM
2.5
particle fractions revealed that more than 80% of PAHs measured in winter were bound to the smaller particle fraction (PM
2.5
), except for Chry, IP and DahA. In summer, more than 60% of measured PAHs were bound to PM
2.5
particles, except for DahA, while in spring, more than 50% of measured PAHs were bound to PM
2.5
particles, except for Flu, BaP and BbF. Furthermore, comparing PAH content in PM
1
and PM
2.5
fractions, we found that most PAHs were bound to particle fraction PM
1
, and the percentage of PAHs in PM
1
was the highest in winter (more than 90%). Factor analysis showed that most of the PAHs bound to PM
10
, PM
2.5
and PM
1
probably had identical sources in winter, spring and summer (house heating and traffic), and the only significant difference in origin was found in autumn for PAHs bound to PM
2.5
and PM
1
fractions.
The present study was undertaken in order to determine the quality of indoor pool waters in hotels along the Croatian coast. We wanted to assess the risks of exposure to microbial and chemical ...contaminants and find out if training pool operators to use a quality assurance system, that we developed, influenced hygienic conditions and water quality in swimming pools or not. The samples were analysed for free chlorine, pH and several microbiological indicators according to standard laboratory methodologies. Of 1,329 samples tested, 276 were found to be unacceptable either by chemical (148) or microbiological parameters (128). After training, the proportion of unacceptable samples dropped by 23.5%, mostly according to the free chlorine values. According to our results, most of the microbiologically unacceptable samples had chlorine levels within the recommended range but their pH values were too high. A free chlorine level below 0.2 mg/L was found in 106 (82.8%) microbiologically unacceptable samples suggesting the need for maintaining the lower limit at least above 0.2 mg/L in order to reduce microbial risks to a more acceptable level. This measure combined with training of pool operators might result in reduced health risks in pool waters.
Aware that exposure to stuffy indoor air with high levels of carbon dioxide (CO
) is associated with higher absenteeism and reduced academic performance in school pupils, the World Health ...Organization (WHO) Regional Office for Europe initiated indoor air quality surveys in schools, including CO
monitoring, to assess ventilation and exposure to stuffy air. Here we report the findings of the first such survey in Croatia. It was conducted in 60 classrooms of 20 urban and rural elementary schools throughout the country during the heating season. Measurements of CO
levels showed that all 60 classrooms exceeded the international guidelines of 1938 mg/m
. Mean CO
concentrations ranged from 2771 to 7763 mg/m
. The highest concentration measured in urban schools was 7763 mg/m
and in rural schools 4771 mg/m
. Average CO
levels were higher in continental schools (3683 mg/m
) than the coastal ones (3134 mg/m
), but all demonstrate poor ventilation during the heating season all over Croatia.
Eating and lifestyle habits of first (n=169) and sixth (n=272) year students, aged 18 to 26 years, attending a Medical School in Zagreb, were compared related to the years of study. A ...self-administered questionnaire created for this study incorporated a food frequency questionnaire. Both year students reported similar number of meals per day, irregular consumption of meals, skipping breakfast, frequency of vegetables, fruits, cereals, sweets, milk and dairy products consumption, body mass index (BMI) calculated from self-reported weight and height and alcohol consumption. Significant differences between groups were observed in consuming supper (p = 0.001), being on diet (p = 0.032), intake of supplements (p = 0.041), meat (p < 0.001), dried meat (p = 0.027), coffee and tea consumption (p = 0.016), physical activity (p = 0.041; p = 0.016), and smoking (p = 0.029). This study showed non-healthy eating arid lifestyle behavior among Medical School students. We observed association between the year of study, and some of the eating habits and lifestyle factors.
Potresi su prirodne katastrofe koje možemo očekivati u bilo kojem dijelu Zemlje u bilo kojem trenutku. Učestalost im je veća u cirkumpacifičkom i mediteransko-transazijskom seizmičkom pojasu.

Hrvatska se nalazi u seizmički aktivnom području, što dokazuje niz katastrofalnih potresa, od kojih velik broj i na zagrebačkom području. Posljedice potresa najviše će ovisiti o gustoći naseljenosti i seizmičkoj otpornosti zgrada. Okolišne posljedice najčešće uključuju zagađenje zraka, vode i tla. Učinci takvog zagađenja mogu imati dugoročne posljedice na zdravlje populacije. Najdramatičniji, akutni, zdravstveni učinci potresa posljedica su rušenja zgrada. Pri tome brzo i djelotvorno medicinsko djelovanje ovisi ne samo o dobroj organizaciji i pripremljenosti zdravstvenih djelatnika nego i o spremnosti i opremljenosti civilne zaštite, vatrogasne službe i pripadnika Gorske službe spašavanja (HGSS).

Najvažnije je istaknuti da smanjenje potresom izazvanih razaranja, budući da je rušenje zgrada najveći rizični čimbenik potresa, uključuje postavljanje prioriteta u izgradnji seizmički sigurnih zgrada.
Earthquakes are natural disasters that can occur at any time, regardless of the location. Their frequency is higher in the Circum-Pacific and Mediterranean/Trans-Asian seismic belt. A number of sophisticated methods define their magnitude using the Richter scale and intensity using the Mercani-Cancani-Sieberg scale. Recorded data show a number of devastating earthquakes that have killed many people and changed the environment dramatically. Croatia is located in a seismically active area, which has endured a series of historical earthquakes, among which several occurred in the Zagreb area. The consequences of an earthquake depend mostly on the population density and seismic resistance of buildings in the affected area. Environmental consequences often include air, water, and soil pollution. The effects of this kind of pollution can have long-term health effects. The most dramatic health consequences result from the demolition of buildings. Therefore, quick and efficient aid depends on well-organized health professionals as well as on the readiness of the civil defence, fire department, and Mountain Rescue Service members. Good coordination among these services can save many lives Public health interventions must include effective control measures in the environment as secondary prevention methods for health problems caused by unfavourable environmental factors. The identification and control of long-term hazards can reduce chronic health effects. The reduction of earthquake-induced damages includes setting priorities in building seismically safe buildings.
To investigate the relationships between body mass index (BMI), dietary habits, and cardiovascular risk factors in isolated Adriatic island populations of Croatia.
Random sample of subjects (n=1001) ...was interviewed, using a validated questionnaire developed for this research program. Dietary habits were assessed on the basis of applied Food Frequency Questionnaire (FFQ). Biochemical analyses of total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides, and blood glucose were performed. Blood pressure (mm Hg), height (m), and weight (kg) were measured following standard procedures.
Out of 1001 study participants, 507 (50.7%) were overweight (247 48.7% men and 260 51.3% women), whereas 268 (26.8%) were obese (122 45.5% men and 146 54.5% women). In both genders, there was a positive correlation between body mass index (BMI) and levels of triglycerides (P<0.001), glucose (P<0.001), diastolic blood pressure (P<0.001), and systolic blood pressure (male: P=0.002, female: P<0.001). Logistic regression showed that female gender (OR, 2.31; 95% CI, 1.61-3.31), overweight (OR, 1.97; 95% CI, 1.34-2.88), obesity (OR, 1.90; 95% CI, 1.22-2.96), more frequent consumption of meat (OR 1.17; 95% CI, 1.06-1.30) and beer (OR 1.14; 95% CI, 1.03-1.27), and less frequent consumption of potatoes (OR 0.91; 95% CI, 0.83-0.99) were predictive for the presence of cardiovascular risk factors.
Prevalence of obesity and related health outcomes was surprisingly high for the studied population. We found a correlation between BMI, dietary habits, and cardiovascular risk factors.

The aim of this study was to investigate the dietary habits of the adult Croatian population according to geographical regions and gender. Date was obtained from the Croatian Adult Health Survey ...questionnaire, carried out in six regions of Republic of Croatia (Eastern, Northern, Central, City of Zagreb, Mountainous and Coastal), with a total of 9,070 responses. Results have shown that the highest prevalence of unhealthy dietary habits was recorded in Eastern and Central regions, while Coastal region and city of Zagreb had significantly lower prevalence of unhealthy dietary habits (P < 0.05). Prevalence of unhealthy dietary habits was higher in men in all regions. Women had healthier dietary habits, what was strongly expressed in Coastal and Mountainous region. This study has shown that the unhealthy dietary habits were practiced by approximately one quarter of the adult population, regardless on the region in which they resided. Regional differences in dietary habits should be taken into account in any new public health studies and interventions.
The aim of this paper was to analyze the regional pattern of physical inactivity in Croatia based on the Croatian Adult Health Survey 2003 data. A total of 9,070 adult respondents were included in ...this study. In men, the highest prevalence of physical inactivity was recorded in the City of Zagreb (39.6%), and it was significantly higher than in Central (25.6%), Coastal (25.6%) and Mountainous region (14.1%). Mountainous region had significantly lower prevalence of physical inactivity compared to any other region, except the Central region. The highest prevalence of physical inactivity in women was also recorded in the City of Zagreb (43.6%), and it was also significantly higher than in all other regions. The lowest prevalence of physical inactivity was recorded in Eastern Region (24.7%). The highest levels of physical inactivity in both in both genders were recorded in urban regions, suggesting that intervention measures in terms of health promotion should be undertaken, with strong emphasis on the people living in urban settings.
