In the present study, the samples of leachate of compost plant in Isfahan city were sampled in the winter of 2010. Physicochemical parameters including: pH, EC, phosphate, sulfate, biological oxygen demand (BOD), chemical oxygen demand (COD), total solid (TS), total dissolved solid (TDS), and total suspended solid (TSS) were measured using standard methods and HACK DR 2800. High level of phosphate (624.88), sulfate (1955.55), BOD (32300), COD (68000), TS (86500) TDS (55900), TSS (31600), pH (5.3) and EC (12.9) on the basis of mg/l for all of the parameters except pH and EC was observed. Potential of pollution leachate of compost plant in Isfahan considered to leachate pollution index (LPI (. Leachate Pollution Index (LPI) for Isfahan of leachate was 54.65. This result showed that leachate produced of solid waste of compost plant in Isfahan high potential have for pollution of the surrounding land and water by the leachate Manuscript profile -

To this end, the vegetables grown around town and industrial center of Zanjan were sampled randomly. Plant samples were digested using hydrochloric acid (HCL) 2 M and concentration of elements (Pb, Zn, Cu, Ni and Cr) were recorded by atomic absorption. Obtained means of heavy metals in all vegetables (N= 32) for Zn, Pb, Cu, Ni and Cr is 98.8, 31.9, 19.3, 4.4 and 2.3 mg/kg, respectively. The highest amount of metal pollution index (MPI) in the basil and the lowest was observed in the garden cress (respectively 16.46 and 4.88). Daily intake (EDI) for zinc, copper and chromium in all age groups was lower than the provisional tolerable daily intake (PTDI). This amount for nickel was 2, 1.6 and 1.3 %, and for Pb 28.1, 22 and 19 % higher than PTDI in children, adults and seniors, respectively. The potential risk (THQ) was calculated in all age groups as Pb>>Cu>Zn>Ni>Cr. The potential risks (THQ) of chromium, nickel and zinc were calculated lower than 1, for copper a bit more of 1 and for lead much higher than 1. Health index (HI) for children, adults and the elderly was estimated 31.331, 24.58 and 21.14, respectively, with the largest contribution of the lead (89.7%). Manuscript profile -

4 - An analysis of the air pollution caused by the industrial town of Rajah using from the matrixmethod (case study of Reja Babol region)
mohammad Motamedi ahmad araeeyanToday, the issue of pollution caused by industrial settlements is a very important issue in environmental studies, which have a significant impact on the ecosystem of the region where industrial settlements are built. In this research, the effect of pollution caused by MoreToday, the issue of pollution caused by industrial settlements is a very important issue in environmental studies, which have a significant impact on the ecosystem of the region where industrial settlements are built. In this research, the effect of pollution caused by the factories of Rajah Babol industrial town on the air of the town is investigated and we try to find solutions to deal with it by presenting suitable scenarios. First, similar domestic and foreign studies were reviewed. SPI and AQI indices were introduced and their limits and corresponding classification were determined. Finally, by using the concept of Leopold's matrix, possible scenarios were introduced to minimize the pollutants in Reja industrial town. The results show that the harmful effects of suspended corn and pollutants can be significantly reduced by controlling the quality of smoke emitted from industrial-production factories and expanding green space. Index of pollution standards, information related to the concentration of ozone pollutants on the surface of the earth, suspended particles. It provides carbon monoxide, sulfur dioxide and nitrogen dioxide. The results of the questionnaire show that the worst possible scenario is the relocation of the industrial-production unit, and the best scenario is the use of vegetation and green space in the areas of the industrial town. Another suitable scenario is to control the smoke coming out of factories by optimizing fuel consumption and using suitable filters. Manuscript profile -

5 - Investigating the concentration of heavy metals and soil pollution indicators in west of Tehran

Tehran metropolis is one of the cities with high air pollution, which can be deposited in the soil and observed in the long term. In this research, in order to evaluate the concentration of heavy elements from the soil of the three areas of the 21st district of Tehran municipality, 10 samples were prepared with three repetitions and a total of 90 samples. Sampling was performed from a depth of 0-20 cm with three replications. Degree of pollution, pollution load index, and ecological risk index were used to assess pollution. Comparison of the concentrations of heavy elements and the trend of their changes showed that the accumulation of these elements has been created in the soil surface. The mean concentrations of the studied elements in zones 2 and 3 were higher than zone 1 (P-value < 0.05). Based on the results, the concentration of the studied elements in regions of two and three were higher than area one (P-value <0.05). Also, the pollution index being higher than one, indicates a high concentration of heavy elements compared to the background concentration in the studied area. The results of this research showed that due to the increasing development of urban and industrial areas in west Tehran, the soil of this area is highly exposed to heavy elements. Therefore, it seems necessary to regularly monitoring the soil of the region in terms of heavy elements and to carefully check the origin of these elements. Manuscript profile -
