Abstract Distribution and diversity of macrophytes in relation to some physico-chemical factors in the Ketar River were studied from December, 2017 to November, 2018. Physico-chemical parameters and macrophytes were collected from three stations along the river for eight months. Onsite measurements and laboratory work of physico-chemical was analyzed as recommended by APHA [31]. Macrophytes were collected manually using belt transect method. Except for pH and surface water temperatures, all the physico-chemical parameters measured showed no significant difference spatially. During the study period, sixteen macrophyte species belonged to fourteen families were identified. Among the identified macrophyte, 11 of them were emergent, while 3 were rooted with floating leaves and 2 free-floating. Free-floating macrophytes were shared the highest abundance followed by emergent. This research observed that the site (site 3) that was exposed to minimal human impact was rich in diversity and abundance of macrophytes. All the sites were dominated by emergent macrophytes that attained the highest relative frequency followed by rooted emergent species. Azolla nilotica and Pistia stratiotes were shared the highest abundance and were the dominant macrophyte with the relative frequency of 7.24% and density of 40.91%, and 7.93% and 26.54%, respectively. Under a favorable environment, nutrient loading from nearby creates more favorable conditions for the infestation of the invasive species (A. nilotica and P. stratiotes) to flourish and out-compete the other species of macrophyte. Therefore, anthropogenic activities that enhance nutrient addition to the River should be regulated.

Soil serves as a more reliable index for productivity than water qualities. The productivity of any pond depends largely on the quality of bottom soil that is “store house of nutrients.” The present paper deals with the study of physicochemical parameters like organic carbon, pH, Electrical conductivity, Nitrogen, Phosphorus, Potassium of soil from Muthannan Kulam,Coimbatore (March 2013- May 2013). Analysis for the above parameters indicated contamination of the soil quality due to some anthropogenic activities.

Seven species of parasites viz. Trichodina domerguei, Trichodina reticulata, Chilodonella cyprini, Myxobohts koi, Dactylogiroides tripathi, D. extenswi and D. catlarius were found from 640 fry-fingerlings of silver carp, Hypophthalmicthys mohtrix (Valenciennes), grass carp, Ctenopharyngodon idella (Valenciennes), European carp, Cyprinns carpio (Linnaeus), small carp, Puntius gonionotus (Bleeker), katla, Catla catla (Hamilton), rui, Labeo rohita (Hamilton-Buchanan) and mrigal, Cirrhina mrigala (Hamilton- Buchanan) from different nurseries and rearing ponds of Mymensingh and Bogra districts of Bangladesh during June, 2004 to October, 2005. The overall percentage of infestations in two study areas was the highest (95%) in winter, moderate (48%) in summer and the lowest (34.8%) in the rainy season. The physicochemical parameters of water exerted more or less significant combined effect on the occurrence of parasites. Key words: Ectoparasites infestation, Carps, seasonal prevalence, Physicochemical parameters.   DOI = 10.3329/bjsir.v43i3.1158Bangladesh J. Sci. Ind. Res. 43(3), 411-418, 2008

The pollution status of Lagos Lagoon was investigated to determine some physical and chemical parameters, in order to further understand its water quality. Five locations were selected according to the anthropogenic activities taking place in the areas. The measured parameters are water temperature, salinity, conductivity, pH, dissolved oxygen (DO) and alkalinity. The mean values ranged from 28.50-30.15°C for temperature, 7.86-8.50 for pH, ND-10.60‰ for salinity, 0.18-15.20µS/cm for electrical conductivity, 12.00-14.00 mg/l for alkalinity and 1.60-6.40 mg/l for dissolved oxygen. The statistical analysis of the measured physicochemical parameters revealed non-significant difference (p>0.05) across all stations in the physico-chemical parameters. Generally, the values obtained suggest the influence of anthropogenic activities especially the depletion of DO in most of the stations. Therefore, point source and non-point source pollution into the Lagos Lagoon should be controlled for the health and safety of the aquatic ecosystems. Generally, all the measured parameters were either below or within the permissible limits obtainable in the marine environment.

Seasonal sampling of the seawater column and sediment in Adriatic coastal areas affected by various anthropogenic activities, primarily aquaculture, was conducted during 2017. In total, 32 samples from two sites (central and southern Adriatic) were analysed by 16S rRNA amplicon sequencing. This approach was selected to test the possibilities of using metabarcoding in studying marine cyanobacteria, exploring their ecology and potential as an indicator group in anthropologically stressed coastal environments. Additionally, physicochemical water column parameters, sediment granulometry and composition were assessed. Water column revealed a seasonal variation of amplicon sequencing variants (ASVs) closely related to Cyanobium PCC-6307, Prochlorococcus MIT9313 and Synechococcus CC9902, as well as seasonal grouping of physico-chemical parameters in PCA analysis. Sediment analysis uncovered greater community richness of 13 cyanobacterial genera and two uncultured groups. The most abundant in sandy gravels and gravelly sand type of sediments were ASVs closely related to Pleurocapsa PCC-7319 and Xenococcus PCC-7305. Furthermore, identified cyanobacterial ASVs predominantly displayed similarity to isolates from tropical areas (e.g. Neolyngbya, Chroococcidiopsis, Trichodesmium, etc.), which could indicate the tropicalization process already ongoing in the fish fauna of the Adriatic Sea.

Anthropogenic activities have accelerated the process of eutrophication and threatened the health of aquatic ecosystems in Lake Baringo basin. This has necessitated the analysis of its spatial variation in its physico-chemical qualities. Physicochemical parameters from 10 sampling sites distributed throughout Lake Baringo catchment. Mean values of temperature were high at the river inlets and Islands compared to the rivers. While pH and Electrical Conductivity (EC) were relatively constant across the sampling points, Total Dissolved Solids (TDS) were high at the inlets and Islands compared to the rivers, Total Nitrogen mg/ (TN), Nitrates (NO3-) Ammonia ( NH3 ), Total Phosphate (TP) Phosphate and Orthophosphate (OP) were relatively higher in the rivers compared to the inlets and Islands. Temperature ranged between (33.8oC) to (21.4 oC), pH (8.88) to (7.18), EC (543 µS/cm) to (224 µS/cm), TDS (433 mg/L) to (181mg/L), salinity (0.2ppt) to ( 0.01ppt), TN (9.98 mg/L ) to (1.32 mg/L), nitrate (5.11 mg/L) to (0.09 mg/L), NH4 (0.77 mg/L) to (0.09 mg/L), TP(2.91 mg/L) to (0.25 mg/L), OP (1.84 mg/L) to (0.09 mg/L). Nitrite values were below the detectable values <0.05. The result of the study revealed that Lake Basin is highly polluted and undergoing drastic eutrophication due to increased nutrient loading resulting in deterioration of the water quality.

Rivers in the North West Province (NWP) of South Africa are polluted by various anthropogenic activities that are associated with agricultural, domestic, industrial, and mining activities. Pollutants and effluent resulting from these activities impact the physico-chemical and biological characteristics of river water. More particularly, domestic and agricultural pollution has been associated with the occurrence of pathogenic yeast species in water. The aim of this study was to determine physico-chemical parameters, yeast levels, and the antifungal susceptibility of pathogenic yeasts in river water. Physico-chemical parameters and yeast levels were determined using standard procedures. Yeasts were identified by biochemical tests and 26S rRNA gene sequencing. Disc diffusion antifungal susceptibility tests were conducted on identified potential pathogenic yeasts. Physico-chemical parameters were within target water quality ranges (TWQR) for livestock farming but were mostly out of range for irrigation. Yeast levels (incubation at 37°C) ranged from 363 to 1 778 CFU/L. There were significant differences (p < 0.05) in the physico-chemical parameters and yeast levels between some seasons and among the river systems under study. A positive association was observed between temperature, COD and yeast levels in all the river systems. Ascomycetes, which were the most prevalent isolates, were identified as Candida spp. (35%), Pichia spp. (13%), Cyberlinera spp. (12%), Meyerozyma spp. (11%), Clavispora spp. (10%), Saccharomyces spp. (6%), Kluyveromyces spp. (5%), Yamadazyma spp. (4%), Trichosporon spp. (3%), and Wickerhamomyces spp. (1%). Antifungal resistance of the potential pathogenic yeasts was as follows: flucytosine and miconazole (100%) > fluconazole (78.5%) > econazole, and miconazole and ketoconazole (49.6%) > nystatin (15.2%). The river water systems explored in the study are used for agricultural, domestic and recreational purposes. Direct contact with the water, especially by immune-compromised people, may pose a health threat and should be further investigated.

Through anthropogenic activities such as dam building, river management works, indirectly through developments and disturbances in the landscape of the watersheds in particular effluent discharges and deforestation increasingly threatened the environmental integrity of freshwaters systems, world wide. In order to access the monthly and seasonally variations of “Ropar Weland”, study on various physio - chemical parameters was carried out from October 2015 to September 2017 at four representative sites (S1, S2, S3 and S4). The seasons were generally divided into winter (December to February), summer (March to May), monsoon (June to August) and autumn (September to November). Maximum amount of all the parameters except DO and free CO2 were observed in summer and monsoon season and minimum in winter season. Minimum value of DO and free CO2 during summer season is due to the higher temperature because temperature is inversely proportional to DO. Rest of the parameters such as phosphate, sulphate, magnesium, calcium were widely fluctuated according to seasons and are under permissible limits.

However, it can also be added to an aquatic system by anthropogenic activities. The aim of the present study is to determine the total As content in the Palea Kavala river (NE Macedonia, Northern Greece). The correlation between As content and some chemical and physico-chemical parameters of the samples was also examined. Research demonstrated significant As concentrations in the water and the sediments of the river. No correlation was found between As and pH, Fe, Mn in the water samples. Concerning the sediment samples, positive correlation was revealed for As with Fe and Mn content, while negative correlation was revealed between As and pH. This is probably indicative of a higher arsenic mobility in the Palea Kavala river water than in sediments. Since no anthropogenic activities were observed in the river’s catchment area, elevated As concentrations are probably due to the lithology of the broader area and especially the presence of extended ore mineralizations including As-bearing sulphide minerals. However, the research in the study area is in progress since a more detailed evaluation of the local sources of As and mechanisms of As release is required.
