The present study was aimed to analyze the influence of industrial and agricultural wastes on quality ofKosi river water, Rampur, UP, India. The results of the present study revealed pH values of between 7.2 and 6.3 (neutral to slightly acidic), the electrical conductivity between 129.4 μs/cmto399.3 μs/cm. The maximum EC value was observed at S5 in spring season. The turbidity of each was 0.4 to 7.067 NTU. The highest turbidity observed at S5 in winters. Total hardness of 73 (mg/L) and 506.33 (mg/L) were evident at S4 and S7 sites respectively. The BOD values ranged from 10.5 (mg/L) at S4 to 137.4 (mg/L) at S5. Higher BOD values at each site are reflecting the great extent of pollution. The minimum COD recorded at S3 (32.60 mg/L) however maximum recorded at S5 (168.65 mg/L). The results of the heavy metals showed a significant increase in the concentration of Pb, Zn, Cu, Hg and As at S5 as compared to the other sites. The As concentration was 0.04, 0.08, 0.85, 0.72 and 0.71 at S2, S3, S5, S6, and S7 respectively. These values were higher than the value of Arsenic as per WHO guidelines.The average concentration of Zn obtained was 0.05, 0.786, 0.413, 0.06, 3.26,0.97 and 0.53 mg/L at S1, S2, S3, S4, S5, S6, and S7 respectively. The highest value of Zn was recorded at S5 (SDP) as compared to other sites. Only at S5 the zinc content is exceeding the normal value. The copper content found to be lower (1.0 mg/Ll) than permissible value according to WHO. The Cu concentration was 0.01, 0.06 0.01 at S4, S5 and S6 respectively, at S1,S2, S3 and S7 zero. The changed physicochemical parameters and occurrence of heavy metal ions indicated a significant level of pollution in Kosi River.

Groundwater samples were collected in Erode city, Tamilnadu, from an area having large number of textile dyeing units. Though people residing in this area use river water supplied by local bodies as their major source for drinking, groundwater is also used as complementary source. The samples collected were subjected to systematic analysis using the standard methods and procedures. The values obtained for different physicochemical parameters were compared with the standard values given by ISI/ WHO. Variations in many physicochemical parameters were observed for most of the samples when compared to the standard values. More than half of the samples collected had their EC, TDS, total hardness, calcium, magnesium, sulphate and chloride exceeding their acceptable limits. This attempt has been made to determine the quality of groundwater in the study area confirms the deterioration of groundwater quality in the area and calls for some effective measures to be taken urgently to minimize the adverse impacts that may occur due to the contamination of groundwater.

The study was conducted to explore the physicochemical parameters of water, fish diversity andfisheries resources of Korotoa River at Bogura city of Bangladesh during July 2015 to February 2016. Thewater samples were collected from five sampling stations in the Korotoa River during wet and dry seasons.The results of the study showed that temperature, EC, TDS, DO, BOD, alkalinity, acidity and total hardnessof the Karotoa River water were 25.86ºC, 297.41 ?S/cm, 98.86 mg/L, 2.17 mg/L, 2.64 mg/L, 122.05mg/L, 3.28 mg/L and 75.59 mg/L, respectively. The DO and BOD contents of the river water were foundunsuitable for fisheries when compared with the standard of DoE. A total of ten fish species under six ordersand seven families were identified during the study period. The study also revealed that the most remarkablecause of water quality degradation of the river was waste dumping (58%) followed by urbanization and riverbank erosion. The water quality degradation (46%) negatively influenced the abundance of fish species. Theresults concluded that the water quality of the river is not favorable for production of fishes and other aquaticorganisms. The study suggested that the source of water quality degradation should be closely monitoredtogether with the industrial effluent and/or domestic sewage discharge should be reduced or stopped throughthe initiatives of the local government concerned to maintain sound and healthy ecosystem of the river.

Abstract The quality of river water is essential for the survival of living beings, whether for agricultural, livestock or human consumption. This study was carried out in the province of Junín, in different districts of Huancayo, the analysis of the samples was carried out in the continental university, from which the data were obtained for comparisons. This investigation revealed that the Chanchas river water has a higher concentration of pollutants during the afternoons since the pH is 8.69 (alkaline), being within the environmental quality standards, however these waters are not recommended for irrigation because it would cause plants do not absorb nutrients properly. Likewise, it was shown that the pH values of the drinking water of the four districts are similar, being 7.36, verifying that it is within the maximum permissible limit and suitable for consumption.

Physico-chemical properties and heavy metals content of soils were determined from seven farms in Minna, central Nigeria. Conventional analytical methods were employed to determine the physico-chemical properties and the heavy metals were analysed by atomic absorption spectrometry. The result showed that pH values ranged from 6.64 - 7.70 indicating slight acidity to slight alkalinity of the soils. The total organic carbon values ranged from 0.95-2.25 % resulting in the presence of organic matter (1.63-3.87). The electrical conductivity values ranged from 17-37 μS/cm. The cation exchange capacity of the soil samples ranged from 3.68-5.15 cmol/kg. The heavy metals levels were in the following range: Cd (0.00018-0.00134 mg/g), Cu (0.0069-0.0476 mg/g), Fe (1.942-2.2059 mg/g), Mn (0.1825-0.3696 mg/g), Ni (0.0065-0.0069 mg/g) and Zn (0.0157-0.2252 mg/g). The concentration of the metals in the soil samples varied according to the following trend: Fe>Mn>Zn> Cu>Ni>Cd. The average concentration of all the metals in each farm also gave the trend Farm B>Farm G>Farm E>Farm C>Farm F>Farm D>Farm A. The findings indicate the presence of heavy metals in all the farms but only Fe was above the FAO/WHO standards.

The paper describes specific changes in the quality of the Danube river water under the conditions of backwater effects in the Hydropower Plant Djerdap I storage. The results of longterm tests in five profiles of the investigated section, at various discharges give a global view of the intensity of changes in the composition of water mass. The analysis included changes in the contents of: organic matter, oxygen regime, reduction of turbidity and changes in the composition and abundance of plankton. The specific changes in the domain of physico-chemical and biochemical processes and changes in the biological status of the watercourse (composition and structure of plankton) at varying retention times complete the picture of short-term changes in the investigated system. Presentation of some settling effects and processes in the sediment of the storage provides an idea of some long-term changes in the conditions of backwater effects of the Danube in the investigated section.

ABSTRACT The purpose was to evaluate the effects of gender and of different genotypes of chickens on the physicochemical parameters and centesimal composition, related to the quality of meat. The design was completely randomized arranged in 5x2 factorial scheme, five genotypes (Índio Gigante - IG; New Hampshire - NHS; Gigante Negra de Jersey - GNJ; poultry from the crossing between the IG and NHS breeds - IG x NHS; and between the IG and GNJ breeds - IG x GNJ) and two genders, with five repetitions and each one represented by three poultry, totaling 150 animals, slaughtered at 105 days. The parameters evaluated on the breast and thigh were: centesimal composition (moisture, ether extract - EE, protein and ash), ultimate pH, color (L*- luminosity, a*- redness, b* -yellowness, C* - chroma index and h* - hue angle), weight loss by cooking (WLC) and shear force (SF). The IG genotype had the highest average of ultimate pH of the breast (6.03). The NHS and IG x NHS genotypes showed, respectively, higher average of L * (58.93) and a* (1.92) of the breast. The IG, IG x NHS and IG x GNJ showed the highest values of b* of the breast (12.53, 13.37 and 12.69, respectively). The IG poultry showed high average of SF of the breast and thigh (4.79 and 5.01kgf, respectively). The IG x NHS and IG x GNJ genotypes showed the lowest ultimate pH values of the thigh (6.13 and 6.02, respectively). The IG x GNJ genotype showed a high average of b* of the thigh (14.94) and the NHS had a high average of WCL (24.65%). The females showed higher averages of EE on the breast and ash on the thigh (1.03 and 1.11%, respectively). The IG x NHS and IG x GNJ poultry showed higher averages of EE of the breast (1.21 and 1.38 %, respectively). The poultry of IG breed and those from the crossing with NHS and GNJ presented meat quality characteristics more desirable by the consumer in relation to physicochemical parameters and centesimal composition, while genders showed no influence on these aspects.

Freshwaters are among the most threatened ecosystems, particularly in North Africa where urbanization and climate change are exerting an important pressure on aquatic fauna. Long-term investigation of macroinvertebrates is one of the best ways of tracking and understanding the influence of environmental and anthropogenic pressures on community dynamics. In this study, we focus on determining the community structure and diversity of benthic macroinvertebrates as well as the state of aquatic physicochemical parameters in the Bouhamdane Stream, near the outlet of Bouhamdane dam, Seybouse watershed, north-eastern Algeria. We carried out a bi-monthly sampling of macroinvertebrates and nine water physicochemical parameters from September 2017 to July 2018 at three sites. Results show that the collected macroinvertebrates (6756 individuals) belong to 15 families and 12 orders. The abundance of the macrofauna consisted of 88.19% crustaceans, 7.74% insects, 3.7% molluscs and 0.16% annelids. Physicochemical analyzes (depth, turbidity, pH, dissolved O2, temperature, salinity, and conductivity) showed variability among sites. The families of Gammaridae and Baetidae were the most frequent and the most abundant on all the stations. The results indicate that aquatic macroinvertebrates constitute good indicators of the biological quality of water. This study shows that even with the occurrence of regular dam water discharge, the macroinvertebrate community is still able to persist either through adaptation to high water velocity or high colonization rate.
