RESUMO

We investigated metal accumulation in bamboo leaves during three seasons at three urban locations differing in pollution levels. The higher content of Cu, Pb, and Zn in the leaves was in correlation with the highest bioavailable content of these elements in the soil at the most polluted location. The content of leaf trace elements was higher in summer and autumn compared to spring. Scanning electron microscopy with energy dispersive X-ray spectroscopy showed that Si accumulation in bamboo leaves was the highest in epidermis and vascular tissue, and was co-localized with trace metals. Analysis of phytoliths showed co-deposition of Al, C, and Si, implying the involvement of Si in metal detoxification. Compared to a common urban tree, linden, bamboo showed better capacity to maintain cellular redox homeostasis under deteriorated environmental conditions. The results suggest that bamboo can be efficiently used for biomonitoring of air and soil metal pollution and remediation in urban areas.

RESUMO

BACKGROUND: Food safety issues are not a new issue in science, but due to the dynamic changes in the modern world it is as equally important as decades ago. The aim of the study was to address the efforts in the development of a comprehensive food safety system in Serbia, and make specific recommendations regarding the improvement of epidemiological investigation capacity as a useful tool which contributes to improving the public health by joint efforts of epidemiologists and law enforcement. METHODS: We used the methodology appropriate for social sciences. RESULTS: The findings show the current state-of-affairs in the area of food safety and health care system and present some most important weaknesses which have to be overcome. Policy makers need timely and reliable information so that they can make informed decisions to improve the population health in an ongoing process of seeking full membership in the European Union. CONCLUSION: Serbia has to apply significant changes in practice because the current state-of-affairs in the area of food safety and health care system is not so favourable due to numerous both objective and subjective factors. Hence, the policy-makers must work on the development of epidemiological investigation capacities as a firm basis for greater efficiency and effectiveness. Epidemiologists would not stay alone in their work. Law enforcement as well as many other stakeholders should recognize their new role in the process of the development of epidemiological investigation capacity as a tool for the development of a comprehensive food safety system in Serbia.

RESUMO

The United Nations named 2010 as a year of natural disasters, and launched a worldwide campaign to improve the safety of schools and hospitals from natural disasters. In the region of South East Europe, Croatia and Serbia have suffered the greatest impacts of natural disasters on their communities and health facilities. In this paper the disaster management approaches of the two countries are compared, with a special emphasis on the existing technological and legislative systems for safety and protection of health facilities and people. Strategic measures that should be taken in future to provide better safety for health facilities and populations, based on the best practices and positive experiences in other countries are recommended. Due to the expected consequences of global climate change in the region and the increased different environmental risks both countries need to refine their disaster preparedness strategies. Also, in the South East Europe, the effects of a natural disaster are amplified in the health sector due to its critical medical infrastructure. Therefore, the principles of environmental security should be implemented in public health policies in the described region, along with principles of disaster management through regional collaborations.
