Abstract

Aims Lead is emerged as one of the most hazardous elements, existing in the air and soil,
which can create irreparable outcomes in the human body due to its highly severe damages.
the aim of this study was to determine the relationship between Lead level and the respiratory
diseases in Tiran & Karvan Region, Iran.
Instrument & Methods The research methodology was analytical based on the documents
and evidence, and library studies and was performed during 2011 to 2015 in Tiran & Karvan
Region, Isfahan Province, Iran. The respiratory diseases statistics regarding the studied area
was gathered from the information and statistics of Isfahan University of Medical Sciences
and Iran Management Center for Diseases during 2007 to 2009 documents (3215 cases).
110 soil samples and 55 water samples were collected from different positions at Summer
2011, randomly. The variation map of the respiratory diseases and lead spatial distribution
for research area were drawn by Arc GIS 10.2 software.
Findings The concentration of lead was 59.4±7.9ppm in soil and 48.2±4.1ppm in water of
the region. The lead variation map showed that the soil in the eastern, northern and western
areas consists of a relatively high portion of lead. Also special distribution of the respiratory
diseases in Tiran & Karvan showed that the disease variation is in a cluster manner and that
the disease follows a special centralization.
Conclusion There is a direct relation between respiratory diseases distribution and the
existence of lead in Tiran & Karvan Region, Isfahan Province, Iran.
