“…For instance; a research performed by Uyar and Ören (2012) in Zonguldak city has revealed that the amount of arsenic was higher than European countries excluding Italy due to Catalağzı Thermal Power Plant (CATES), Ereğli Iron and Steel Station (ERDEMIR), the use of coal for heating purposes and trafficderived emissions (Uyar and Ören, 2012). In another study by Uyar et al (2009), amounts of heavy metals in Zonguldak and Kdz. Ereğli were detected to be higher than Europe (Uyar, 2009).…”

ABSTRACT:This research is focused on the examination of child cancer cases in Zonguldak (Turkey) descriptively in epidemiological aspect thanks to GIS. Universe of the study is composed of 60 children between 0-19 years old, treated in Children Oncology Clinic of Health Application and Research Center in BEU. Whole universe was reached without selecting a sample in the study. Data were collected by using a form prepared by obtaining expert advice and they were applied to children and their parents at study dates. Results were expressed as percentages. Chi-Square test was used in intergroup comparisons, results were assessed within 95% confidence interval and p<0.05 was considered as statistically significant. Variables that were used in the study were assessed, recorded in prepared data collection form and distribution maps were produced. When disease diagnosis of the children participated in the study were evaluated, it was observed that 33.3% (n=20) were being treated for ALL, 13.3% (n=8) for Medullablastoma and 11.7% (n=7) for Hodgkin-nonHodgkin Lymphoma. It was detected that 31.7% (n=19) were in Ereğli, 31.7% (n=19) were in Central district and 18.3% (n=11) were in Çaycuma, when the places where children were living were evaluated. Statistically significant difference was found (p=0.016) comparing disease diagnosis with living place, and overall distribution map of the number of cancer cases was produced in this context. This is the first research subjecting the distribution of cancer cases for Zonguldak province.

“…They are also passive accumulators of heavy metals and some radioactive isotopes. Morphological and genomic variations caused by high accumulation of heavy metals make them useful for modeling (Bassi et al, 1995) and biosensor studies (Uyar et al, 2009). Contrary to higher plants, bryophytes have a relatively high surface/volume ratio and a differentiated epidermal layer without cuticle; thus, they absorb heavy metals with their whole surface in higher amounts (Sun et al, 2009).…”
