The experiment was carried out during 2005 at the Weed Research Department of the Iranian Crop Protection Research Institute, in a factorial form on a completely randomized design with three replications. Wheat cultivars in four levels (Shiraz and Niknejad, as more competitive cultivars; Tabasi and Roshan, as less competitive cultivars) and the density of wheat seedlings on four levels − 0 (control), 8, 16 and 24 − were considered as factors. Mean comparison showed that higher seedling density (at 24) had the greatest effect on decreasing rye growth (seedling, radicle, and hypocotyl) and all of the wheat cultivars showed a decrease in seedling, radicle and hypocotyl length in comparison with the control. All the wheat cultivars, especially at the highest density, decreased seedling and radicle length, but increased the hypocotyl length of field bindweed.

There was no pesticide contamination in fish samples of Astara. Heptachlor in muscle tissue of Cyprinus carpio from Anzali had the highest concentration (11.964 mg/kg - lipid weight basis) among all fish samples. Mean level of each pesticide was calculated in all fish samples. The results showed that among other pesticides, heptachlor is the main contaminant in southwest of Caspian Sea (2.6479 mg/kg - lipid weight basis). Generally, in comparison with Acceptable Daily Intake (ADI) established by FAO/WHO, the levels of heptachlor in muscle tissue of Cyprinus carpio from Anzali and Ramsar, Rutilus frisii from Hashtpar and level of dieldrin in muscle tissue of Rutilus frisii from Kiashahr can have health risk to consumers. The concentration of above mentioned pesticides in the same fish samples are higher than Maximum Residue Limit (MRL).

In order to evaluatethe effects of agricultural practices on these organisms, a study was conducted in winter wheat fields of Shirvan, Mashhad and Gonabad, three regions of Khorasan Province. In each region, high and low input fields of winter wheat were selected, along with a natural system for comparison. Use of agricultural inputs was the criterion for the selection of low and high input fields in each region. Soil sampling was undertaken on fields and natural systems. Organic matter and the number of nematodes and culturable bacteria in soil samples were measured. The percentage of soil organic matter in all systems was low but, in agro-ecosystems, it was greater than in natural systems. Results showed that organic matter, soil moisture and mean annual temperature has an affect on soil nematodes. The number of nematodes in agro-ecosystems was reater than in natural systems in all three regions. The mean number of soil nematodes in 100g dry weight of soil in the natural systems of Shirvan, Mashhad and Gonabad was 166, 184 and 132, respectively; in the low input systems of Shirvan, Mashhad and Gonabad it was 550, 459 and 1067, respectively and in the high input systems of Shirvan, Mashhad and Gonabad it was 348, 1084 and 485, respectively. Agricultural practices had no negative effects on soil bacterial numbers and the number of soil bacteria increased in some agro-ecosystems.

In sampled stellate sturgeon, Heptachlor with an average concentration of 3.933 mg/kg on lipid weigth basis and Aldrin with an average concentration of <0.288 mg/kg on lipid weigth basis had the highest and lowest concentrations, respectively. The order of these pesticides according to average of concentration are as follow: Heptachlor > DDT > Lindane > Dilderin > Aldrin.

The fish species found were: Alburnoides bipunctatus, Barbus capito, B.lacerta, B.mursa, Capoeta capoeta, Leuciscus cephalus, Salmo trutta, Onchorhynchus mykiss, Nemachilus bergianus.B.capito and B.mursa are both highly prized taxa in terms of their population status and for sport fishing; the latter needs full habitat protection to survive.Salmo trutta will face little impact from the Alamut Dam construction since its habitat is mainly confined to a stretch of river well upstream of the construction site. It should be kept in mind, however, that the Manjil (Sefid Rud) Dam has some affect on the operation of the Alamut Dam, both being constructed on the same water body. Therefore, any interpretation of the possible impact of the Alamut Dam on hydrobiology of the area must be focused on the entire water basin ecology.

This study was conducted at Arghavan reservoir in the North of Ilam Province in Iran. For this study, plots with a systematic distribution across the northern (n =24), southern (n =20) and western (n =13) aspects were selected and vegetation, soil and physiographic data were measured. Results showed that, in the southern aspect, ground vegetation diversity had a negative relationship with clay and sand while it had positive correlation with silt. In the northern aspect, ground vegetation diversity had a negative correlation with elevation above sea level. In the western aspect, ground vegetation diversity had a positive correlation with CaCo3 while it had negative correlation with salinity and elevation above sea level. Results also showed that, in all the aspects, woody species only had a relationship with physical factors. These results suggest that in ecological studies for assessing the relationship between vegetation and environment, soil factors should be measured for the assessment of ground vegetation and, for woody species, physical and physiographic factors.

Therefore, improper collection methods and uses can cause environmental problems. This study was conducted in order to investigate the effect of municipal soild waste compost leachate (MSWC leachate) on yield and yield components of wheat (Triticum aestivum) with four irrigation treatments of different leachate-to-water ratios (T0=water, T20=20%,T40=40%, T60=60% V/V basis) in a completely randomized design with three replications under greenhouse conditions. Results obtained indicate the significant effect of different leachate to water ratios on ECe, pH, TN, available P and OC of soil, yield and yield components of wheat. ECe, TN, available P and OC of soil increased, but the soil pH decreased with MSWC leachate concentrations and the maximum was recorded for the T60 treatment. The number of grains per spike (more than 1.4 times), plant height(13.8%), grain weight per spike (more than 1.6 times), grain and straw yields (more than 1.5 and 1.6 times, respectively), and the ratio of grain weight to straw weight in a leachate-to-water ratio of 20/80 (T20) treatment increased when compared to their respective controls and the other treatments (p≤0.05). Spike length and 1000 grain weight in a leachate-to-water ratio of 20/80 (T20) treatment were not significantly different from their respective controls. Increasing the leachate concentrations to more than 20%, reduced yield and yield components of wheat compared to control, probably due to a soil salinity increase and its negative impacts on the parameters studied (p≤0.05).

Using enrichment in medium containing coal as sole carbon source, seven bacterial strains able to grow on coal hydrocarbons were isolated. The bacterial consortium was then cultured in mineral salt liquid media containing 1% (w/v) hard coal or coal tailings and incubated for 15 days at 25 degree centigrade on an orbital shaker (150 rpm). Spectrophotometric analysis of supernatants resulted from centrifugation of cultures showed 1.475 increases in absorbance at 450 nm for coal tailing and 0.832 for hard coal, compared to blank lacking bacteria.
