المستخلص: Several air pollutant concentrations such as Suspended Particulate Matter (SPM), carbon oxides (COx), sulfur dioxide (SO2), nitrogen oxides (NOx), methane (CH4), ozone (O3) and some heavy metals such as lead (Pb) , chromium (Cr), cadmium (Cd), and nickel (Ni). Were measured in selected areas of the Rusafa in Baghdad, Anda’lus square (as a commercial site) and Wazeria district (as industrial site).The results showed that the concentration of air pollutants from gases, SPM (NO2, CO, SO2, and SPM) and heavy metals (Pb, Cr, Cd, and Ni) were exceeded globally and locally permissible limits in both study sites, while the concentration of O3, CO2 were within the globally and locally standard limits in both study sites. Commercial site had recorded higher concentrations of (CO2, SPM, Pb) than those of industrial site. While the industrial site had more pollution with (NO, NO2, CO, CH4, Cr). Results showed a relationship between climate factors and air pollutants, where windspeed, temperature, and relative humidity had influenced on the concentration of air pollutants.Median Lethal Concentration (LC50) to nitrogen dioxide gas was identified, by exposing a community of 30 adult male mice. The mice weights were between 23 - 31gm and their age was 8 - 12 weeks. The mice were randomly divided into five groups (6 male of each group). The exposure periods were 20, 40, 60, 80, 100 minutes using different concentrations 50, 100, 150, 200 ppm.The results showed a higher mortality during 150 and 200 ppm concentrations, for exposure periods of 80 and 100 minutes, but other concentrations have not been recorded. LC50 was calculated 161.86 ppm for 80 minutes and 110.53 ppm for 100 minutes.

المستخلص: تضمنت الدراسة الحالية التاثيرات السمية الحادة والمزمنة لمبيد 2, 4 - d في نوعين من اسماك الكارب (الاعتيادي والعشبي)، استعمل في دراسة التاثيرات الحادة عدة لكلا النوعين قيد الدراسة وكانت ((170, 165, 160, 155, 145, 140, 130 و(140, 130, 115, 95, 70)ملغم/لتر ع | This study included acute and chronic effects of 2, 4 - d pesticide in two species of carp fish (Cyprinus carpio and Ctenopharyngodon idella) using several concentrations for the two carp fish species that were (130, 140, 145, 155, 160, 165, 170) and (70, 95, 115, 130, 140) mg/l respectively for 96 hours, to determine the median lethal concentration (LC50) and the behavioral changes was used as a standard of those effects. Whereas three concentrations (20, 40 and 60) and (10, 15, 25) mg/l respectively for the two carp species were used in the chronic exposure for six weeks. The behavioral, histological and hematological changes were used as a standard to observe these effects through the study period. The value of LC50 for common carp fish were 157.77, 157.25, 156.41 and 152.62 mg/l. For grass carp, LC50 were 115.92, 114.92, 112.94 and 96.52 mg/l for 24, 48, 72, 96 hrs of exposure to 2, 4 - d pesticide concentrations respectively.Behavioral changes were recorded more effects in high concentrations than in low concentrations. To discover the toxic effects of this substance on fish, many parameters were used. They included the clinical symptoms by erratic swimming, hyperactivity, loss of equilibrium with respiratory effects such as rapid gill movement and swam near the water surface. While in chronic effects, blood parameters were changed in Red Blood Cell R.B.C., White Blood Cell W.B.C., Packed Cell Volume P.C.V., Haemoglobin Hb and liver enzyme (GPT & GOT).Values elevated significantly according to the pesticide concentration (P?0.001) and exposure periods (P?0.05) in comparison with control. The histological examination of the gills, liver and kidney of the common and grass carp fish after chronic exposure to 2, 4 - d herbicide showed pathological changes and alterations such as fusion of the secondary lamella, epithelial lifting, blood congestion, epithelial hypertrophy of the lamellar epithelium and epithelial necrosis. In the liver, pathological changes were seen, including hepatocytes hypertrophy, cytoplasmic vacuolation, blood congestion and cellular necrosis. Degenerative changes of the renal epithelium, necrosis in renal tubules and occlusion of the tubular lumen where the pathological alterations in the kidney.

Air temperature at sampling time was varied from 16°C to 42°C and from 10°C to 34°C, for water temperature at sampling time also. The results of pH values were within the allowable limits, ranging from 7.1in autumn to 8.1 in summer. For EC, the highest value recorded for raw water was in winter with 1338 µs/cm, while the lowest value was in spring with 920 µs/cm. The highest value recorded for drinking water was again in winter with 1330 µs/cm, and the lowest value was 910µs/cm in spring also. The highest value of turbidity recorded for raw water was in winter with 89 NTU and the lowest value was in spring with 26 NTU, while the highest mean value recorded for drinking water was 20 NTU again in winter and the lowest value was 1 NTU in spring. The study showed that the results of TDS values ware ranged from 622 mg/L in spring to 1024mg/L in winter. The highest value of residual chlorine was recorded in summer with 4.5 mg/L; the lowest value was zero mg/L in some of the farthest points of the plants. For sulfates, values were ranged from 289 mg/L in spring to 498.4 mg/L in winter. All the recorded values of chlorides ions for all water samples were within the allowable limits, its values ranged from 98mg/L in summer to156.3 mg/L in winter. For total hardness, the values were exceeding 500mg/L and allowable limits for Iraqi standard criteria. The highest value recorded for raw water was in winter with 520 mg/L and the lowest value was in summer with 351 mg/L, while the highest value recorded for drinking water was again in winter with 516mg/L and the lowest value was 337 mg/L in summer also. For calcium values ranged from 75 mg/L in summer to 135 mg/L in winter. The results of this study showed high levels of lead, cadmium and aluminum in most water samples which collected during study period compared with those that exceeded the acceptable limits provided from the quality control unit and which are considered to have adverse effects on health. For lead, values were found to vary from 0.0030 mg/l in summer to 0.16 mg/l in winter (higher acceptable limits is 0.01 mg/L). While in case of cadmium the values lied between 0.0014 mg/l in winter and 0.015 mg/l in summer (higher acceptable range is 0.0030). However, for aluminum these data were ranged from 0.0062 mg/l in raw water during spring to 0.29 mg/l in drinking water during spring also (higher acceptable range is 0.2). The current results showed an increased in the number of autotrophic bacteria, total coliform, fecal coliform, fecal streptococci, and E. coli during winter season in most study locations as compared to those of the other seasons for both water plants raw and drinking water while the FS values were less than those of other bacterial types for both water plants. The Total plat count results of drinking water were exceed 100 cell/ml, the allowable limit for drinking water, for some samples of both water plants. on the other hand, the TC, FC and E. coli exceeded zero cell/100ml, the allowable limits for drinking water, in many drinking water samples for both water plants
