Carcinogenic and human health risk assessment of children's and adults' exposure to toxic metal(oid)s from air PM10 in critical sites of the Republic of Serbia.

With global urbanization and industrialization, air pollution has become an inevitable problem. Among air pollutants, toxic metals bound to particulate matter (PM) have a high hazardous potential, contributing to the development of several diseases, including various types of cancer. Due to PM pollution, Serbia is considered to be among the most polluted countries in Europe. Therefore, the objective of the study was to assess and characterize the non-carcinogenic and carcinogenic risks of children's and adults' exposure to metal(oid)s (Pb, Cd, Ni, and As) bound to PM10 in five of the most polluted areas in the Republic of Serbia (Subotica, Smederevo, Bor, Valjevo, and Kraljevo). Non-carcinogenic (HQ and HI) and carcinogenic risk (CR) were calculated using USEPA methodology. Our results show that PM10 concentrations exceeded the annual limit of 40 µg/m3 at four out of five monitoring sites (ranging from 44.33 to 63.25 µg/m3). Results obtained from Bor monitoring station show that safe limits were exceeded for both children and adults, indicating an unacceptable risk (> 1) obtained for inhalation exposure to the As (HQ = 6.14) and Cd (HQ = 1.17), while total HI was 7.43, which characterized the risk as unacceptable. For the same station, the CR value was 1.44E-04 (> 1 × 10-4). In other sites, the risks were acceptable. The characterized risk from exposure to the toxic elements via PM10 in critical locations in Serbia contributes to improving air quality by requiring regulatory organs to take new actions and adopt new measures to reduce air pollution.

Changes in the organizational structure of public health nurse service in the Republic of Croatia 1995 to 2012.

Since 1996, after the privatization of primary health care, public health nurse (PHN) in Croatia remained employed within the health center, mainly responsible for the preventive care of the inhabitants from defined catchment's area. Before that time they were part of general practice teams. The main aim of the study was to investigate what are the trends in the organizational structure of PHN service in Croatia, from 1995-2012. The main source was the Croatian Health Service Yearbooks. The obtained results shows that they are college educated and mostly in full-time jobs. The important findings are the lack of nurses and theirs regional differences. In highly demanding societies, with growing numbers of elderly, mental, social and economic problems, it will be worthy to consider the lower standard then 5 100 inhabitants per one PHN. Also, it should be taken into account to invest into the lowering of regional disparities.

Did the structure of work in the public health nurse service of the Republic of Croatia change in the period 1995-2012?

In Croatia, public health nurses (PHN) have been members of family doctor (FD) teams for decades, conducting a multifunctional and polyvalent scope of activities, including health promotion, prevention, as well as part of the treatment for the inhabitants of a defined catchment area. The main aim of the study was to investigate the trends in the number and structure of PHN visits in the period from 1996 to 2012. The main sources of data were Croatian Health Service Yearbooks. The results strongly indicate that PHN's are overloaded by a high number of visits, especially to chronic patients. While mothers and new-born children are in the PHN care, pregnant women and small children are rather neglected. Considering different working conditions and differences in population needs, a review of the standard is recommendable.
