First International Environmental Health Conference, HEALTH AND THE ENVIRONMENT IN IRAQ: Status, Needs & Challenges Amman, Jordan, September 19-22, 2005 Sponsored by Stony Brook University and the Agency for International Development, Higher Education and Development. Program Director Prof. Dr. Wajdy Hailoo, Stony Brook University, NY. NEURAL TUBE DEFECTS AMONG INFANTS DELIVERED OF MOTHERS WITH TOBACCO SMOKE EXPOSURE A. A. Mahmood Kufa College of Medicine, Kufa, Iraq Goals and Objectives: Verify the incidence of neural tube defects (Anencephaly /meningomyelocele) among infants delivered of the pregnant mother who had prenatal history of tobacco smoke exposure and to test the association between such variables in Najaf governorate, Iraq. Design: A cross sectional Study on Pregnant women who were delivered at maternity hospital. The sample was subdivided into exposed and unexposed women to tobacco smoke. Methods: A systematic random sample of pregnant women who attended the major maternity and children hospital in Najaf city during the period 2002-2004. A sample of 2300 delivered women were selected and interviewed for history of indoor smoking exposure whether they were heavy smokers or passively exposed from their heavily smoking husbands in addition to taking folic acid tablets before and during pregnancy .They were adjusted for dietary folate deficiency and other confounders which may be attributable to congenital anomalies development. The newborns were clinically examined by a pediatrician for presence of any congenital anomalies especially neural tube defects. Results: The over all newly delivered newborns within the period of study with congenital anomalies were 3.4% (including small defects). The most frequent neural tube defects were spina bifida (1.2% ) and anencephaly ( 1.8% ) among those who were heavily exposed to smoking versus 0.6% and 0.8% respectively among non smokers and passively unexposed women (P<0.05) . 98% of mothers did not have previous delivery of such defect. There was no significant difference in the incidence of congenital anomalies between those who took folic acid tablets and those who did not Neither between those women who live in urban or rural areas or between different age groups for neural tube defects. Conclusion: There was an increase in the incidence of neural tube defects without previous affected siblings among mothers with heavy exposure to tobacco smoke. Folic acid prescription may not prevent the occurrence of these defects among exposed mothers. ASSESSMENT OF PULMONARY FUNCTIONS AMONG COTTON TEXTILE WORKERS IN BAGHDAD A. Al-Saidi and W. Al-Tawil National Center of Occupational Health and Safety, Ministry of Labor, Baghdad, Iraq Goals: Evaluation of health status of Iraqi Textile Workers. Objectives: To asses the magnitude of respiratory health problems of inhalation cotton dusts by textile workers. This cross-sectional study covers registered 358 records for the period from Jan.30th 1996 till Jan.30th 2003 for clinical and spirometry assessment done by National Center of Occupational Health and Safety .Spirometry includes FEV1,FVC and FEV1/FVC percent for each worker. Statistical Analysis includes percentages, chi –square and Ztest. Selected Toxicology-Related Abstracts 2 of 5 Results: Out of 358 employees 56 show abnormal lung function tests (15.64%) and all of them are males. The majority of workers with abnormal lung function tests were from the carding room (67.85%) followed by blowing section (25%) then blending room (5.35%). The majority of workers (98.22%) with abnormal lung function tests have duration of employment of (10-24) years.There is statistically significant association between abnormal lung function tests and long duration of work 15 years of exposure or more. Out of 56 employees with abnormal lung functions tests, 25 employees are smokers (44.64%). Also 51.95% of abnormal lung functions test (29 employees) have clinical signs and symptoms as classified by international classification.The majority of workers with abnormal pulmonary function tests (83.95%) have obstructive type of ventilatory defect while 12.50% have combined type and two employees with restrictive type only. Conclusion: Duration of exposure is an important factor in pulmonary function abnormality. Carding and blowing rooms are the mostly affected Sites where exposure occurs. Obstructive lung disorder is the prominent type.The middle age groups are the mostly affected. Smoking is an important factor increasing the severity of pulmonary function impairment. Recommendation: Periodic Medical Examination.The current clinical evaluation reflects the possibility of the high dust exposure although no available data are found. Therefore abiding to the international standards (100μ\m3) is recommended. Workers with atopia should replaced in a relatively dust free areas. Worker's compensation for occupational disability should be available. Technical support to the National Center for Occupational Health and Safety is highly recommended. A STUDY OF MORBIDITY PATTERN WITH SPECIAL REFERENCE TO OCCUPATIONAL ALLERGIC DISEASES AMONG WORKERS OF THE STATE COMPANY OF FERTILIZERS, BASRAH A. Al-Yassen and N. Ajeel Department of Community Medicine, College of Medicine, University of Basrah, Basrah, Iraq Goals/Objectives:Examine the general morbidity pattern of workers over a specified period of time. Determine the impact of the exposures to hazardous agents in the workplace with special reference to the development or exacerbation of allergic diseases. A cross sectional comparative study was carried out in the state company of fertilizers/southern which is one of the important companies in Iraq. This research was designed to study the relationship between exposure to gases and dust in the workplace and allergic diseases. Three exposed groups (workers in ammonia & urea, water refinery, and packing departments) were compared to nonexposed control group (workers in administrative departments).The results showed that the prevalence of work-related allergic conditions as reported by workers and diagnosed by the investigator were significantly higher among the exposed groups than the control group. Similarly, the total serum immunoglobulin E (IgE) levels were significantly higher in the exposed groups than in the control group. A clear significant effect of the degree of exposure to hazardous gases and dust on total serum IgE level were observed. These findings suggested that the risk of workrelated allergic diseases were higher among workers exposed to irritant gases and dust than among their controls. The overall results of the present study indicate the need for enhancing occupational health measures with a special attention to preventive and promotional aspects. LEVELS OF POLLUTION BY LEAD IN BASRAH, IRAQ A. Al-Saboonchi, A. Al-Marashi and A. Ali Department of Fishery, Basrah University, Basrah, Iraq Goals: Monitor the levels of lead in environment of the south part of Iraq. Objectives: Assess the lead level in roadside dust and plant leaves in Basrah and detect the lead level in the blood of traffic police. Levels of lead in dust of road sides, plant leaves and blood from traffic police-men were measured, during summer season, 2004. Dust of road sides were collected from different stations. Extracted with EDTA and levels of it were measured after dilution by atomic absorption spectrophotometer. Dithizon spectrophotometer techniques were used for extraction of lead in leaves of plants and blood. Study concluded that the levels of lead in dust range between (99-416) mg\kg while in plant leaves the highest value of (5.15) ppm\cm2 near Ashar river and the lowest value (1.09) ppm\cm2 at Abu Al-Kassib. In case of blood the highest value of lead (92) mg\100 ml found in traffic policeSelected Toxicology-Related Abstracts 3 of 5 men with 15 years serves, while the lowest value (15.1) mg\100 ml is recorded in traffic police-men who serve only 7 months. HEALTH EFFECTS CAUSED BY LEAD ABSORPTION AMONG BATTERY MANUFACTURING WORKERS IN THE PRIVATE SECTOR IN BAGHDAD IN CONTRIBUTION WITH W.H.O. E. A-K. Saber National Center of Occupational Health and Safety, M.L.S.A, Baghdad, Iraq Goals: Locate and study the impact of such hazardous industries which were created due to the influence of the new situation our country is living under now a day on the environment and human health. Objectives: 1) Assess the health effects resulting from lead absorption among workers employed in repairing old damaged liquid batteries in Baghdad city. 2) Determine the impact of this phenomenon on the environment and people residing in the vicinity of such work places. This survey was carried out on the private reinstalling and repairing workers in small industries and work shops, in comparison to a group of workers in big factories not dealing with lead during their usual daily work, in Baghdad city. A group of researchers at the N.C.O.H.S. conducted this survey The survey was carried out aiming to assess the health effect resulting from lead absorption among the battery repairing workers and to determine the impact of this phenomenon on the surrounding environment and people residing in the vicinity of such work places. A modified standardized questionnaire was distributed to all the participants. Blood and urine samples were taken from each participant in addition to air samples collected from work places and inspired by the workers. All these samples were analyzed for lead content and ALA / Cr in the laboratories of the national center of occupational health and safety (N. C. O. H. S.) in Baghdad. Also the survey studied the environmental conditions of the work places as well as the methods of disposing their liquid waste products.The survey revealed a wide, irregular and unorganized spread of these work places in almost all Baghdad industrial, commercial and even the residential areas. This might to a great deal be the cause of pollution o
