Study of The Effect of Environmental Pollution of Cadmium on The Respiratory Efficiency and Physiological Blood Parameters of a Sample of Wood Carpentry Workshop Workers

Abstract: This study aimed to evaluate the impact of environmental Cd pollution on respiratory efficiency and blood physiological parameters in a sample of wood carpentry workshop workers, given their ongoing exposure to dust and fumes from chemicals such as paints and adhesives that may contain lead compounds. In this study, 50 carpenters and 20 non-carpenters were selected, with ages ranging from (20-50) years, and they were divided into two groups: 1- The first group: the control group 2- The second group: was exposed to the carpentry workshop environment for a period of (5-10) years, with working hours of (6-12) hours per day. Physiological analyses were conducted for the two groups, with heart rate and oxygen saturation being measured. After that, a health questionnaire consisting of 20 questions was presented to determine the health and psychological status of the two groups and to compare the symptoms statistically. The results showed a significant decrease in respiratory efficiency in the exposed workers, compared to the control group. Blood Cd levels were significantly higher than the normal range. Physiological changes in the blood, such as decreased hemoglobin concentration and abnormal blood cell counts, are observed. There is a direct relationship between the duration of exposure and deterioration in health indicators. The study recommends educating workers about the risks and implementing strict control policies to reduce occupational exposure to cadmium.
