“…This result conforms to the findings of Lottıg et al (2011), who noted the significant chemical differences between streams and lakes because of the inputs (flow regimes) to them. In addition, the negative relationships of these variables with elevation were also reported by Wılcox et al (1957) and Yavuzatmaca (2020b). Electrical conductivity and elevation were also showed to cause the heterogeneities among three water basins in Turkey (Yavuzatmaca 2019).…”

“…These streams start from high altitude and flow towards lower altitude by collecting water that allows one to think that their hydro morphological structures and environmental conditions are very similar to each other when compared to lakes. The reason is that snow and rainwater with low percolates into the soil directly flow to the stream bed at high elevations since the soil here is saturated with water and there is less transpiration (Wılcox et al 1957). They also reported an increasing trend in the pH and salt contents of the soil profiles of the Mission Creek watershed from 6180 (1883.7 m asl.)…”

Ostracods are one of the most suitable organisms because of their ecological and morphological preferences for habitat types to study the diversity between streams and lakes. Here, 24 streams and 16 lakes were sampled in 2019 to evaluate the species compositions between streams and lakes. Environmental heterogeneity in the sense of the physico-chemical variables was found among the habitats. 24 of the 29 species with 923 individuals were found in the lakes when 13 species with 898 individuals were found in the streams. Eight species were common in both habitat types. Species contributing about 70.81% to the significant differences in the species composition between the habitats showed cosmopolitan characteristics. Species variation among the replicates of lakes were higher than streams. Results indicated that the species composition was probably associated to dissolved oxygen in lakes, while electrical conductivity in streams. Relationship amid elevational range and ostracod species richness was negative in lakes when there was no clear relationship in the streams. Overall, results suggested that determination of influential regional factors in different aquatic bodies can provide important contributions to the estimation of which habitat types can be chosen by species, and the using of species as bioindicators.

“…It was explained by lower decomposition rate of organic matter compared to the higher elevation. Therefore, it seems that TOC accumulates in the soil of higher elevations (18,19). In a similar research, it was reported that increasing altitude has a positive significant effect on organic matter in soil.…”

of roads runoff pollutants (4). Pollutants transferred with road runoff are divided into suspended solids, heavy metals, biodegradable organic matters, organic micro-pollutants, pathogenic organisms, nutrients and petroleum products (5). Without treatment, these components may find their way directly into surface water or penetrate into the soil of the roadside (1). Since organic pollutants are associated with particles and sediments, they are possibly more serious during Journal of Human, Environment and Health Promotion Journal homepage: www.zums.ac.ir/jhehp Background: Contamination of water and soil through non-point sources such as road runoff causes environmental concern. The aim of this study is to determine the effect of Zanjan-Chavarzagh road on the total organic carbon (TOC) content of sediments in tributaries and the river that lead to Taham Lake. Methods: In tributaries and the river 69 soil and sediment samples were taken and the Total organic carbon (TOC) was measured according to Walkely-Black method. Also, Taham Dam Basin area and its hydrologic properties were calculated by Global Information System (GIS) software. Results: Results showed that, TOC concentration has a significant negative relationship with the distance from the lake. TOC in soil samples taken from hillside of the road had significantly lower mean and median concentration (median= 3262 , mean = 4083 ± 3461 mg/kg) than the valley side (median = 5324 , mean = 6178 ± 3980 mg/kg). The check dams across the tributaries and the river have not been effective in the reduction of TOC in sediments. Conclusion: Roads in the Taham Dam Basin, increases TOC content of soil and sediments in Taham dam basin. TOC moves toward Taham dam lake.

“…The other environmental factors retained by the forward selection procedure are closely related to altitude. For instance a negative correlation between conductivity and elevation is generally observed (Wilcox et al, 1957;Rundle et al, 1993) and the positive correlation between altitude and the percentage of boulders reflects the sediment transport implying the presence of larger rocks mainly in the upstream part and finer sediments in the downstream part. This altitudinal distribution of habitats is underlined by a clear differentiation of the taxa distribution.…”

-In order to assess the impact of water release in the downstream area of the Nam Theun 2 Reservoir (Lao PDR), the spatial and temporal variation of benthic macroinvertebrates was explored. Between 2010 and 2012, five sites were monitored in the Nam Gnom Basin, a tributary of the Xe Bangfai River, receiving the turbinated waters. Repeatedtime collections revealed the presence of 109 taxa mainly identified to the family level, attesting to a rich biota. Preliminary results did not show shifts in diversity, population composition, and feeding metrics. Redundancy Analysis indicated that the altitudinal gradient (i.e. altitude and altitude-related variables) remained the major environmental factor influencing the macroinvertebrates distribution before water discharge. The presence of a tributary downstream of the release point, and the respect of the natural river inflow can explain the preservation of natural conditions. More samples and a strengthened ecological knowledge of Southeast Asian macroinvertebrates are still required to confirm these preliminary results.Key words -freshwater invertebrates, Southeast Asia, biomonitoring, hydropower, downstream section Résumé -Afin d'évaluer l'impact du relâcher des eaux dans la zone aval du Réservoir Nam Theun 2 (RDP du Laos), la variabilité spatio-temporelle des invertébrés aquatiques a été étudiée.
