Abstract: Many minute microscopic plants and animals spend their life in the floating manner in water. These suspended organisms form the plankton. Phytoplankton is the single cell plants are the bases of all other life forms on planet earth and are responsible for making up to 90% of earth oxygen. It is believed that most of the world oxygen comes from tiny oceans plants Phytoplankton are important influence upon the earth climate because they consume CO2. In 2010 group of marine scientists based in Canada reported that phytoplankton has declined globally by 40% since 1950 These scientists suggested that warming of ocean surface due to climate change might have reduced the vertical mixing of the water column reducing the supply of nutrients from deeper water. Nutrients that are essential for phytoplankton growth.......

Abstract: Though sedimentation, disinfection filtration, and coagulation/flocculation are capable approaches of treatment for IWW, certain chemical contaminants can't be removed with such techniques; therefore, they required applying advanced approaches. Presently, AOPs are amongst the best often applied approaches to eliminate contaminants that may have less-biodegradability or great chemical constancy. AOPs approaches needs free hydroxyl radical (HO*) as an oxidant for the degradation of toxic pollutants that can't be removed via traditional methods. In current comprehensive-overview, we have reported several AOPs which revealed evidences in contaminant elimination from IWW

Abstract: Present paper embodies the seasonal macroinvertebrate community dynamics of Halali reservoir which is 40 kms away from the Bhopal. The work was carried out seasonally during winter, summer, monsoon and post-monsoon seasons 2010-2011. A total number of forty two macoinvertebrate species have been recorded from four sampling stations that belong to eight groups namely Diptera, Odonata, Crustaceae, Ephemeroptera, Oligochaeta, Hirudinea, Gastropoda and Bivalvia. The sequence of their abundance were found in the order- Gastropoda 19 species (45.23%), Diptera and Oligochaeta 6 species each (14.28% each), Odonata and Bivalvia 3 species each (7.14% each), Ephemeroptera and Hirudinea 2 species each (4.76% each), Crustacea 1 species (2.38%).

Abstract: In Niger, the use of cowpea and Bambara groundnut storage methods against Callosobruchus maculatus (Fab.) depends on social categories. In total, 404 households were interviewed in 16 villages (Mallé, Matankari, Goubawa, Sabarou, Tchito, Kamreye, Kaiwa Ganwo, Goubaye, Badiffa, Issakitchi, Barbousaye, Wande Beri, Rougaguin Nakikarfi, Doromawa, Gazobi and Ido Bissa) belonging to Tillabéri, Dosso and Maradi. Thus, from this study it emerged that 95% of each social category uses the seed to the detriment of the pod for storage. In fact, for cowpea storage, PICS bags are used more by the better-off (61%) and the middle (61%) than the poor (38%) and very poor (24%). In the same idea, PICS bags are used more by the Better-off (43%) than the middle (39%), poor (24%) and very poor (24%) in the storage of Bambara groundnut seeds. This study also showed that more than 50% of each social category..............

Abstract: Background:Solid wastes disposal sites provide a livelihood to thousands of waste handlers and waste scavengers. Sporadic fires within the dumpsites and wastes decomposition lead to emission of fugitive gases such ascarbon monoxide (CO) and Hydrogen sulphide (H2S); resulting to deleterious health effects to the exposed workers.Increased CO and H2S in ambient air also displace oxygen (O2) gas levels which in extreme cases can lead to asphyxiation. This study assessed the levels ofCO, O2 and H2S in selected dumpsites in Kenya. Materials and Methods: The study sites were inThika, Ngong, and Kawangware in Kenya. Levels of CO, O2 and H2S were determined using a Multi gas monitor (model GX2012) during working hours at the dumpsites and control sites away from active dump.Analysis of variance was used to analyze the different parameters in the dumpsites. Association between different dumpsites and parameters were tested using student t-test at 95% confidence interval......

Abstract: The seasonal nutritional variability of cultured green mussel (Pernaviridis)were analyzed from July 2019 to June 2020 at the Maheshkhali coastal area of Cox's Bazar, Bangladesh. The present study revealed that the nutritional status was varied from season to season due to its dynamic characteristics of hydrological parameters. The highest protein (13.72%), Fat (5.44%), Carbohydrate (4.82%), Ash (2.46%), Calcium (227.36mg/100g), Magnesium (778.52mg/100g) and Iron (12.32mg/100g) were found during post monsoon season whether Moisture (74.89%) and Phosphorous (560.00mg/100g) were during monsoon period. On the other hand most of the nutritional values were found lower at monsoon season except moisture and phosphorous which is related to high or low of food abundance..........

Abstract: Dissolved inorganic nutrients, mainly from nitrogen and phosphorus components are involved in marine ecosystems eutrophication. The study was undertaken in Biétri Bay, one of the most polluted bays of the Ebrié lagoon in Côte d'Ivoire to assess its waters quality after its volume reduction due to some embankments for the extension of Abidjan Port activities. pH, temperature, salinity and Electric Conductivity (EC) were measured in situ at the sampling stations. Ammonium (NH4+), nitrite (NO2-), nitrate (NO3-) and orthophosphate (PO43-) and twelve (12) trace elements concentrations were determined in waters collected four (4) selected. Measured values of pH, temperature, salinity and Electric Conductivity were in the respective ranges of 7.24-7.82; 20.99-28.77 °C; 25.78-36.66; 40.32-55.46 mS/Cm.......
