2018 Engineering and Technology Journal
Abstract- The microbial quality of drinking water which distributed form Al-Bashaar water treatment plant and number of residential areas fed by these water treatment plant was studied each month over six months during a period extended from the October 2013 to April 2014, through the purification stages up to residential sites at different areas situated with various distances from the supplying source, two samples were taken monthly. This station derived their water from AL-Gharraf River in the southeastern part of Iraq, where the feed areas of the city with drinking water. This study included detection of bacteria, evidence of contamination of water and some physical and chemical variables. Results of Bacteriological tests showed increasing in TPC, TC, FC, E.coli and FS bacteria in December and January in all study locations as compared to those of the other months for water plant raw and drinking water and the FS values was less than other bacterial types for water plant .Physiochemical tests showed that air temperature at sampling time was varied between17 and 34°C and between11.5 and 29°C, for water temperature at sampling time also. The results of pH means were within the allowable limit. The highest mean value of turbidity recorded for raw water was in December and the lowest value was in April, while the highest mean value recorded for drinking water was again in December and the lowest value was in April. The highest mean value of residual chlorine was recorded in March; the lowest value was 0 mg/L in some of the farthest points of the plant. From this study, it can be concluded that the drinking water produced by Al-Bashaar plant is mostly undesirable for drinking according to the Iraqi and WHO standards for the drinking water.
Evaluation of Human Health Risks Associated with Exposure to Disinfection by Products (Dbps) in Drinking Water of Wassit Province Southeast Iraq
3 Baghdad Science Journal
Abstract:The toxicological risks and lifetime cancer risks associated with exposure to disinfection by-products(DBPs) including Halloacetic acids (HAAs) and trihalomethanes (THMs) compounds by drinking water inseveral districts in Wassit Province were estimated. The seasonal variation of HAAs and THMs compoundsin drinking water have indicated that the mean values for total HAAs (THAAs) and total THMs (TTHMs)ranged from 43.2 to 72.4 mg/l and from 40 to 115.5 mg/l, respectively.The World health organization index for additive toxicity approach was non-compliant with the WHOguideline value in summer and autumn seasons and this means that THMs concentration has adverse toxichealth effects.The multi-pathway of lifetime human health risk of cancer credited to THMs and HAAs in drinkingwater via three exposure routes for THMs and only one exposure route for HAAs was evaluated and found tobe 6.13×10-4 and 1.78×10-4 respectively and these values were higher than the US.EPA range of concernlimit of 1×10-6. The risk ratio of THAAs to TTHMs was 3.44. Also, the highest cancer risk was recorded forBDCM followed by DBCM, CF, TCAA, DCAA, and BF

2018 journal of Pharmaceutical Science research
Abstract: This study was established for monitoring the concentrations and seasonal variation of disinfection by-products (DBPs) including trihalomethanes (THMs) and Halloacetic acids (HAAs) in both raw and treated water. Also, developing a model for predicting the formation THMs and HAAs in drinking water systems within the five main water treatment plants (5 WTPs) in Wassit Province. The results have indicated that the mean values for total THMs (TTHMs) and total HAAs (THAAs) in raw water samples ranged from 12.4 to 32.4 µg/L and from 9.6 to 17.5µg/L in winter and summer respectively. While the mean values for TTHMs and THAAs in treated water samples ranged from 30.1 to 139 μg/L and from 37.8 to 88.5 μg/L in winter and summer respectively. Bromodichloromethane (BDCM), dibromochloromethane (DBCM), monobromoacetic acid (MBAA) and chlorodibromoacetic acid (CDBAA) were the major disinfection by products in the raw water while BDCM, DBCM, trichloroacetic acid (TCAA), and dichloroacetic acid (DCAA) were the major disinfection by-products in the treated water whereas dibromoacetic acid (DBAA) was not detected in all samples. A statistical models for THMs and HAAs concentration in Wassit water supply systems have been derived based on measured water parameters and using multiple regression analysis. The performance of predictive regression models for TTHMs and THAAs was good (R2 =0.77 and 0.71 respectively) and showed that the most significant parameters are temperature, chlorine dose, TOC, and UV-254.

2022 Cite as: AIP Conference Proceedings 2398, 040053 (2022)
Abstract: To ensure that people have access to safe drinking water, it is necessary to evaluate quality of the waterproduced in water treatment plants (WTPs) and to maintain high performance efficiency. This work aims at using acombined Comprehensive Pollution Index (CPI) and water quality index (WQI) to evaluate and characterize thewater quality produced by eleven WTPs in Baghdad City and their efficiency during autumn 2019 to summer 2020.Nine water quality parameters (WQPs) including pH, turbidity (TUR.), total dissolved solids (TDS), total hardness(TH), chloride (Cl-), nitrate (NO3-), iron (Fe), Aluminum (Al) and total coliform (TC) were measured. Acomparison of the WQPs levels of the treated water with the World Health Organization (WHO) and Iraqi Criteriaand Standards of water’s chemical limits (ICS) showed that all WQPs exceeded these guidelines except pH andNO3-. Due to the comparison, the water produced by the eleven WTPs was unsuitable for drinking. Based on resultof the CPI classification, the Al-Sader, Al-Baldiat, and Al-Kadhimiya WTPs were slightly polluted, CPI(0.41-1.00)while the other WTPs were medium polluted, CPI (1.01-2.00). The water produced by the eleven WTPs wasclassified in terms of WQI values as poor (51-75) to very poor (76-100) for all WTPs during the study period exceptAl-Wathba, Al-Qadisya, Al-Dora and Al-Rasheed which are classified as Unsuitable for Drinking(WQI>100). In thecurrent study, a new tool was introduced to evaluate the performance efficiency in terms of CPI and/or WQI values. Based on this tool, the efficiency of the eleven WTPs during the study period ranged from low to very low for the older WTPs to medium for the newer WTPs. This assures the necessity to undertake serious actions in monitoring the water treatment plants and in managing it properly

Calculation the Excess Lifetime Lung Cancer Risk and Human Health Risk Assessment by Inhalation of Radon Gas in the Health Centers of Al–Hay City in Wasit, Iraq Using LR-115 Detector
2024 Cross Current International Journal of Medical and Biosciences
Abstract: In this paper, the technology used to measure radon concentrations in 8 health centers of Al- Hay city in Wasit, Iraq (December 2019) is one of the types of solid state nuclear track detectors, LR-115. After that, the annual effective dose rate and the excess lifetime cancer risk were calculated for the selected positions in the study area. The detectors were exposed to radon for 45 days, the etched detectors, using an optical microscope, to calculate the track densities, essentially depend on the alpha ray emitted from radon which later on easy converted to radon concentration values. Radon concentration ranges are from (183.47±22.93 to 17.15±2.14) Bq/m3 with a mean of (100.483Bq/m3), which lower than the appropriate radon levels recommended by ICRP "International Commission on Radiological Protection". The readings of "Excess Lifetime Cancer Risk" (ELCR), which ranges from 3.9 ×10-3 to 8.05 ×10-3 with an average value of 0.53% showing that human health is not under risk even it does not develop any lung cancer while human inhale the radon.

2024 Obat: Jurnal Riset Ilmu Farmasi dan Kesehatan
Abstract. Infertility is one of the most common diseases in the world in last period of all types, whether it is due to (asthenospermia,oligoasthenospermia,teratospermia,hormonal imbalance). Study aims to reveal negative effect of sperm DNA fragmentation on fertilization, this study was conducted in the Al-Jazeera Specialized Laboratory in the city of Kut for the period between (January to November from 2024), two hundred A person suffering from infertility. The semen was examined for all of them, they were divided into eighty of them being normal (the control group) and one hundred and twenty suffering from infertility (asthenospermia) hormonal test and sperm DNA fragmentation test (by Kit methods) was performed for everyone , this study showed Following, we obtained higher proportions of sperm DNA fragmented infertile Which had an abnormal shape and low motility. The results are similar to those of other studies, which found that the DFI in infertile group was significantly higher than that in fertile group (34.53 ± 4.6 % compared to11.91 ± 4.0 %) and mean sperm concentration in fertile group was significantly higher compared to infertile group (83.22 ± 14.9 /ml compared to11.67 ± 10.7 /ml) from this study. Through this study, the DFI test they can be used for discrimination and between the infertile male and normal male . Male men with sperm (DFI ≥ 25.1% ) had a (2.52 ) times higher risk of infertility compared to males with sperm (DFI < 25.1%). This study shows that there is a negative relationship between (spem DNA fragmentation , sperm motility and formation) in infertile males. In addition, it can be concluded that sperm DNA fragmentation is very useful in selecting and choosing suitable sperm to be used in many techniques, including assisted reproductive techniques. It can also be concluded that the results of sperm DNA fragmentation analysis are encouraging and useful and can be used for diagnostic purposes in determining male infertility
