“…After that the samples were filtrated into a 25 ml volumetric flask using Whatman No. 44 filter paper and made up to the mark with distilled water (Bhuyan, et al, 2017).Also, the concentrations of nitrate, TOC, OM and COD were measured according to (ASTM, 2002). Microbiological Examination of water: The total viable bacterial counts (TVBCs) as well as indicators of fecal contamination including (total Coliform, fecal Coliform and fecal Streptococci) were investigated.…”

Assessment of the environmental impact of the polluted water was studied along Bahr El-Bakr drain. Different samples of water, soil and the edible parts of vegetables, cereals and clover were collected from the study area. Chemical and/or microbiological analyses of these samples were achieved to examine water, soil and plant contamination. Chemical analysis of the collected water samples, that represented all irrigation water resources, showed that they range from fresh to brackish. For soluble heavy metals, there is no any inorganic pollutant in the collected water samples except one sample with high aluminum and iron concentrations,while using digestion method, high concentrations of most metals for all collected samples were recorded. On the other hand, high concentrations of organic pollutants included both TOC and COD were detected in most water samples. Microbiological investigation of the water samples revealed their highly contamination with fecal coliforms and pathogenic bacteria. All soil samples of the study area showed remarkable pollution with higher microbial contamination compared to that of irrigation water of the same place.The summary statistics results indicated that the most important heavy metals with regards to potential hazards in studied soils are Pb and Cd. Average contamination factor values for heavy metals have the order Cd > Co > Ni > Cr > Cu > Pb > Zn > Fe, suggesting that soil samples were extremely enriched with Cd, while Pb exhibit significant enrichment. Geoaccumulation index showed that the soils of Bahr El-Bakr were uncontaminated with Fe, Zn, Cu, Ni, Co and Cr and moderately contaminated with Pb but Cd followed strongly/ extremely contaminated index. It was also observed an elevation in nitrate contents in the edible parts of the collected leafy vegetables. Heavy metal concentrations in leaves, cereal, fruits tubers of edible parts of plants and shoots of clover plants decreased in the order; Fe > Al > Zn > Cu > Mn >B >Ni >Cr > Pb >Ba >V >Mo >Co >Cd, with increase of toxic metals such as Al, Cr, Pb, Ni and Cd concentrations that were higher than the permissible limits.These results indicated that long term irrigation with waste water from Bahr El-Bakr drain had a negative impact on both chemical and microbiological quality of soil and plants in this region.

“…In nature, it is found in its tetravalent and divalent forms, with Pb 2+ predominant over Pb 4+ . However, the compounds that this metal forms as the salt of Pb2+ in high concentrations in the aquatic environment is toxic to most life forms [34]. Fe is the fourth most abundant heavy metal in the earth's crust and is also present in natural waters.…”

Livelihoods in developing countries depend largely on intact and functioning wetlands. Water permanence and quality have been identified as factors affecting the structure and composition of biological communities, such as macroinvertebrates and benthic algae [1, 2]. The natural variability of these communities in wetlands faces challenges because of the severe anthropogenic impacts that are being generated in both their structure and the services they provide (groundwater recharge, flood water retention, lotic-based flow contributions, biogeochemical processing, water quality improvement, and wildlife habitat) [2, 4], which is leading to its degradation on both local and global scales [5, 6]. Global wetland studies have revealed a significant decline of 6% in just 14 years (1993-2007) due to

The present study was carried out to monitor and assess the surface soil quality parameters of the Sitalakshya River, Bangladesh. The soil samples were collected from Kanchpur Bridge and Atlapur during rainy and winter season. Soil texture is an important tool that aids in organic matter retention, minerals dispersal, microbial biomass, and other soil properties. The soil of the study area was recorded sandy loam and loam. The concentrations of soil parameters ranged for EC: 65.7 μS/cm-99.83 μS/cm; pH: 6.67-6.97; organic matter: 0.43%-0.66%; and organic carbon: 0.23%-0.35% in the soil of the Sitalakshya River. Most of the parameters showed no substantial variations in respect of sites and seasons (p>0.05) except electrical conductivity and pH (p<0.05). Statistical analysis like correlation matrix exposed the close relationship between organic matter and organic carbon. The soil of the Sitalakshya River has low nutrient contents that are not enough for the plants and organisms. Rapid industrialization and the huge establishment of brickfields are the major factors behind this less productive ecosystem. The river must be protected from further deterioration by taking fruitful management plan. This preliminary study will be a useful tool in the conservation plan. This will also help the future researchers who want to work on the river. Contribution/Originality: The paper contributes the first logical analysis of the soil quality parameters of the Sitalakshya River. The study demonstrated the preliminary ecosystem condition of the river. This will provide baseline information for researchers and policymaker in the conservation issue. 1. INTRODUCTION The soil is a natural component of the environment that constitutes of mineral matter, water, air, organic matter and living community that varies according to place and time [1, 2]. Climate affects the type of rock weathering, removal and the redeposition of materials by wind, water, and glaciers that regarded as a crucial factor for soil formation [3]. It forms a natural buffer and filter system in water and offers a wide range of ecosystem services (e.g. food, fiber, water, and timber) [4, 5]. Soil exert great influence on the environmental quality and have an impact on the climatic conditions; water quality; nutrient cycling; and cultural services (e.g. aesthetic, spiritual, and recreational purposes) [6-8].
