Lignite flyash is one of the major solid waste products coal based thermal power stations of India. In these waste used in cement industries, cement bricks industries, civil construction work and agricultural fields etc. The environmental problems generated by large-scale production of flyash in coal based power stations. This waste alternative using vermicomposting of flyash as good sources of nutrients. The availability of many nutrients is very low in flyash; available ranges of such nutrients must to be increase the effectiveness of cowdund and flyash as a soil amendment. In our experiment, we assessed the possibility of increasing total iron content (mg/Kg), total copper content (mg/Kg), total manganese (mg/Kg), total zinc (mg/Kg) and C/N ratio micronutrients in flyash through vermicomposting. Cowdung and fly ash was mixed with different trios at 1:1, 2:1, and 3:1 ratios (weight by weight). After the findings the 3:1 cow dung fly ash was the suitable combination for earthworm activity, the freshly acclamatized earthworms were inoculated in 15 gms/kg for Lampito mauritii for 10 -50 days. The concentration of above said micronutrient was found to increase in the earthworm-treated samples of cowdung and flyash combinations compared with the control flyash alone. The worm worked composts (vermicomposts) and worm unworked composts (control) considerable amounts of total iron, total copper, total manganese, total zinc and reduction of C/N ratio micronutrients from cowdung flyash into more soluble forms and thus resulted in increased the nutrients in the vermicompost. Among different combinations of cowdung and flyash, nutrient availability was significantly higher in the 3:1 cowdung to flyash treatment compared with the other treatments.

This work focuses on the diversity and spatial distribution of benthic macroinvertebrates in the ichthyological spawning grounds of Lake Buyo. Sampling took place from June 2018 to May 2019 on 11 spawning grounds using a Van Veen grab, a dip net and a dip net. A total of 19,940 individuals grouped into 28 Families, 13 Orders, 6 Classes and 4 Branches were identified. The most abundant Families with a percentage higher than 20 in the study area are Thiaridae (63.33%) and Chironomidae (22.88%). The Insects class is the most diversified with 17 families followed by Gastropods with 8 families. The values of the Shannon-Weaver indices and the Pielou equitability calculated are low, which reflects a low taxonomic diversity and an imbalance in the spatial distribution of benthic macroinvertebrates in the different ichthyological spawning grounds.

The chalk used in educational institutions is of two types, dusting chalk and non-dusting chalk. The regular dusting chalk produces a finer and lighter dust, which is more likely to linger in the air and be breathed in. Non-dusting chalks produce a heavier dust that is less likely to linger in the air. In most of the cases, a lot of the dust is heavier and do not tend fly at all. It is very similar to the regular dusting chalk and still creates dust. The ultimate difference lies in the fact how fine the dust is. Since the dusting chalk paves the way for many allergies this was becoming a problem. But on the other hand, the non-dusting chalks have more chemical composition when compared to dusting chalk. As both the chalks have different compositions, they have their own effect on human health. The present study explores human exposure to the harmful dust when chalk is used for teaching. In this study, a preliminary attempt was made to observe the varied responses of people of various age groups to share their responses on the effects of chalk in their lives through a structured survey. Various health issues caused were reported based upon the dust they were exposed to and concluded accordingly

Forages usually constitute the major portion of the ruminant feeds in our country. Availability of feed containing imbalanced chemical composition and metabolisable energy is major handicap in ruminant production the world over. The present study aimed to evaluate the fibre fractions of Ailanthus excels Roxb. fast growing multipurpose indigenous tree species used as cattle fodder as the leaves are rated as highly palatable and nourishing with high percentage of crude protein. The fiber fractions i.e. Neutral Detergent Fibre (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL) values were measured for Ailanthus excels Roxb. leaves and observed that AD Fvaried from 0.91% to 74 %and the average was recorded as 48.93 ± 8.36 %, NDF ranged from 28.49 % to 94.77 % with an average of 5.6± 0.97 % and recorded the minimum of 0.2% to the maximum of 17.5 % of ADL value. Low or high NDF value indicate the dry matter digestibility and dry matter intake that will result in a decrease or increase in livestock consumption. Hemicellulose and cellulose, the slowly digestible fibre materials present in the cell wall ranged from 1.72 to 82.5 % and 0.45 to 96.72 % respectively. The digestibility of the A.excelsa leaves was tested for 24 hrs and 48 hrs were observed that almost all accessions showed digestibility greater than 50%.Metabolizable energy (ME) and Total Digestible Nutrients (TDN) are the other two energy requirement of cattle other than IVDMD and ME observed to be more than 8.23(MJ/Kg DM) for all the accessions and TDN value more than 40 %. Though fodder is nutrient treasure, the IVDMD decides the nutrient intake by the cattle. With the desirable fibre fraction and promising IVDMD and metabolizable energy values of A. excel accessions can be an alternate tree fodder for cattle during lean period.

The Nanotechnology industry is growing rapidly, leading to concerns about the potential ecological consequences of the release of nonmaterial to the environment. Titanium dioxide nanoparticles (TiO2 NPs) are widely used in commercial products such as sunscreens and toothpastes, industrial products like paints, lacquers and paper, and in photocatalytic processes such as water treatment. Also, TiO2 NPs are indirectly discharged in agricultural soils through irrigation or sewage-sludge application and directly as nanofertilizers or nanopesticides. Soil microorganisms are key contributors to nutrient cycling and are essential for the maintenance of healthy soils and sustainable agriculture. Although the antimicrobial effects of a broad range of nanoparticulate substances have been characterised in vitro, little is known about the impact of these compounds on microbial communities in environments such as soil. This study focused on the acute effects of TiO2 NPs on soil microbial communities such as bacteria, Fungi and Actinomycetes. This research revealed substantial shifts in bacterial, fungal and actinomycetes community composition in soils amended with TiO2. The TiO2 NPs exerted an adverse effect on the microbial population, causing the reduction of bacteria, Fungi and Actinomycetes in the substrate. The viability of the microbial population was reduced at the high concentration (50 mg kg−1) of TiO2. Results demonstrate that microbial communities differed in their sensitivity to TiO2 NPs with its various concentration and the release of TiO2 NPs to the environment has the potential to alter the composition of these microbial communities, which could have implications for the stability and function of soil ecosystems

Gears fishing effort, catch per unit effort and fish productions were investigated in Ebrie lagoon (Aghien sector) from March 2020 to April 2021. Samplings were carried out by mean of artisanal commercial fisheries. Six type of fishing gears namely gillnets, cast nets, bamboo traps, traps, hooks and beach seines were used throughout the lagoon. The highest values of fishing effort were recorded with gillnets and traps whereas the lowest values were recorded with hooks and bamboo traps. About 39% of total catches were recorded with gillnets followed by traps with 18% whereas the lowest CPUE were recorded with hooks, and beach seine with 4% and 12% respectively. The most important value of production was recorded with gillnets (63.678 tons / 52.28%) followed by bamboo traps (19.375 tons / 15.90%) whereas the lowest value of production was recorded with hooks (6.219 tons/5.10%).
