Detecting Organic Materials in Fly Ash using Chromatographic Method

Fly ash, a byproduct of coal-fired power plants, is entirely inorganic and inert, making it unfit for life. In Korba, fly ash is deposited in dykes, which are open embankments. The quest for organic compounds was critical because the humus formation is a revolution in fly ash, and just it will be capable of supporting life forms. This was conducted in the dykes to verify the organic materials source in fly ash, namely, whether they are originated from coal, furnace start-up oil, or animals and plants that grew in the area. Thin layer chromatography and ascending paper chromatography in a liquid medium were used as the method.

Bacteriological Examination of DrinkingWater in Different Public Places with Reference to Coliforms

This ponder explores the contamination level in drinking water in several open places. The bacteriological investigations performed were in accordancewith standard methods. Out of eight tests from distinctive locales all had checks higher than the guidelines. Cinema theaters were the foremost contaminated.

Employing spider webs for environmental investigation of suspended trace metals in residential and industrial areas

Spider webs were gathered from residential and industrial areas to found the order of heavy suspended metals in the air. The treatment of spider webs were done with nitric acid and digested by atomic absorption spectrophotometer before analysis (AAS). The average value of several heavy metals concentration were observed to be meaningfully great at p < 0.05 in suspended ingredients in industrial zones including, Cadmium (Cd) 0.15 ± 0.05 and Lead (Pb) 0.53 ± 0.09 µgg-1, respectively. The average values of concentration of Copper (Cu), Nickel (Ni) and Zinc (Zn) were not meaningfully changed from residential, industrial and control zones. It was observed that, the heavy metals concentration reduces when the web specimens were collected more away from the road.

Effectiveness of Microwave Drying for Shrimp Aquaculture Sludge

The disposal of the shrimp aquaculture sludge requires large area and high amount of disposal cost. The improper treatment and disposal can cause soil and water pollution. Sludge drying is an effective solution to reduce the weight of sludge and eventually reduces the disposal cost. This study was aimed to assess the effectiveness of thermal treatment on drying shrimp sludge at different power and time of 270W, 450 W 630W and 60s to 390s, respectively. Heavy metals concentrations and chemical compounds were also determined. Results reveal that the best drying rate recorded were at power and time of 630 W and 240s, respectively. Fourier transform infrared spectroscopy spectrum (FTIR) shows that the main groups presence are aliphatic chains with double bonds, as well as carbonyl, hydroxyl and N–H groups in organic compounds. Sludge drying has proven to be effective in reducing moisture content and organic matters for shrimp aquaculture sludge. It could be considered as one of the alternative methods to handle sludge.

Assessing Heavy Metal Bioaccumulation in Freshwater Fish at the Gingee River in Puducherry, India

Heavy metal bioaccumulation was investigated in fish from the Gingee river in Vadamangalam and Ariankuppam in the Puducherry area, including mercury (Hg), zinc (Zn), and copper (Cu) (Cu). According to the study, heavy metal concentrations in sediments were more significant than in water. Depending on the season, the amount of heavy metal played at each location changes. Heavy metal bioaccumulation was seen in river fish. Metal concentrations have been detected in the following order: sediment > fishes > water.

An investigation into value of Eutrophication in Hosur Lakes

Our current concern is that nitrogen and phosphorus amounts are rising rapidly, Otherwise, to limit the growth of algae and biomass, it exists in relatively low concentrations in unmodified natural waters. This investigation aims to attempt to measure the level of eutrophication in the Hosur LakesFor this research, we chose three lakes named Chandrakudi Lake, Doddan Lake and Kelavarapalli dam. For dissolved orthophosphate, chemical oxygen need, organic nitrogen, free ammonia, inorganic nitrogen whole phosphorus and soluble oxygen, etc. some exemplars were gathered and examined. The onsite research as transparence, facts on killing fish and deterioration of the lakes conditions, etc. was also accomplished. The eutrophication rate in the lakes was measured using the Wetzel's plan. The results showed that the rate of eutrophication was very high in all three lakes, i.e. more than enough to very rich in nutrients that cause excessive plant growth, which chokes out the animal life in the water.

Occurring the paraquat residues in various Nigerian

Because pesticides are ubiquitous and focused on the food chain, they are a substantial source of possible environmental danger to humans and animals. The highest extremely hazardous herbicides to be launched in 60 years ago is paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride). Although most nations have prohibited or severely limited the use of paraquat (PQ), it is still used in others, particularly in Nigeria. As a result, the present study used a spectrophotometric method to look for PQ in some vegetables, crops, and fruits in Abeokuta that are commonly consumed. The presence and amounts of PQ residues were assessed in 150 samples of various vegetables, crops, and fruits (harvested at Fadama field of the University of Agriculture, Abeokuta). PQ residues were detected in Talinum triangulare, Corchorus olitorius, Amaranthus caudatus, Cratylia argentea, Capsicum frutescens, Lycopersicum esculentum, Raphanus sativus, Zea may, and Dioscorea alata at 0.130.02, 0.27+0.02, 0.06+0.01, 0.10+0.03, 0.15+0.03, 0. Using this technique, no paraquat residues were found in M. paradisicica or C. papaya. At 0.05-1.0 ppm fortification level, the technique yields a mean recovery of over 80% and is reproducible with a total coefficient of variation of 8.0 percent (n=10). All residual levels found were under the PQ tolerance or pesticide maximum limits.

Assessment of the amount of inputted energy and discharged greenhouse gasses from wheat cultivation in Ardabil province of Iran

preventing greenhouse gasses discharge and proper environment maintenance is crucial for human race. For a sustained agricultural development, managing energy consumption and greenhouse gasses discharge (GHG) is important in all agricultural agroecosystem. This study aims to compare wheat cultivation in irrigated and dryland wheat production using energy usage-based greenhouse gas discharge in diverse climatic areas. Throughout 2019, a face-to-face questionary was used to obtain data from wheat cultivators. The total energy usage according to gathered data are 14975 and 54963.9 MJ ha−1 for dryland and irrigated wheat production. In dryland wheat production, energy consumption efficiency was 16% higher compared to energy consumption efficiency of irrigated wheat production. The total amount of GHG for dryland wheat production was 370.5 kg CO2-eq t−1 and 520.62 kg CO2-eq ha−1 and for irrigated wheat production, total GHG was 620.8 kg CO2-eq t−1 and 2986.71 kg CO2-eq ha−1. The order of GHG from low to high in dryland wheat production was chemical fertilizers, machinery, and diesel fuels. In order to reduce the GHG and its environmental effect, efficient energy consumption is vital in wheat production.

Flood Impact Assessment Using HEC-RAS and GIS Techniques Dinder River, Southeast Sudan

Dinder River is largest tributary of the Blue Nile. It is seasonal river that flows from June to November and reaches its high peak in September. Frequently, the water level exceeds the normal height causing over bank flow and consequently floods. The floods generally ring about losses properties and crops close to river banks. This study is attempts to figure out the river flow behavior and find out the aerial extent of inundated lands in four flooding seasons. The investigated area is located in Sennar State, SE Sudan. Discharge data collected over the period from 2015 to 2018 and Digital Elevation Model (DEM) have been used to model the River flow regime, while land cover data was used to determine the affected LU/LC types in the area. HEC-RAS software was used to create 2D unsteady flow model in order to simulate Dinder River flooded area in four seasons. The largest flooded area extent in each season was used as input in GIS environment for further spatial analysis. Statistical computation for the affected area and consequent analysis revealed that: the affected urban area in 2018 was around 28.152km2, in 2017 was 29.205 km2, in 2016 was 16.531km2, and in 2015 was 10.422km2. Similar calculations were carried out for the other LU/LC types. According to the present study, the year 2017 witnessed the largest extent of flooding in the area.
