Charcoal production communities were selected randomly and visited. Multi-stage sampling method was employed to select targeted respondents and interviewed with Google Form semi-structured questionnaire. Three Council Wards and six communities were chosen for the study. A total of 60 respondents were interviewed. Respondents were mostly married (61.7%) males (98.3%) and Christians (81.7%). Majority of respondents (36.7%) were in 21 – 30 years age class, had tertiary education (40%) and were farmers (46.6%). Every respondent (100%) agreed that charcoal was produced in Adoka District while 51.7% indicated 21 to 30 individuals were involved in the charcoal production. Prosopis africana (71.7%), Khaya senegalensis (21.7%), Magnifera indica (5.0%) and Lophira lanceolate (1.7%) were utilized and P. africana (88.3%) was the most preferred. Prosopis africana also used for: firewood (100%), condiment (66.7%), timber (33.3%), medicine (20%) and, food and tools making (16.7%). Most respondents (95%) felled 1 - 5 trees per charcoal production while they daily (98.3%) engaged in the business. Respondents (73.3%) earned N5,000 daily and 66.7% earned above N30,000 monthly; and invested earnings on trading (60%), farming (13.3%), unnamed businesses (18.3%), purchase of motorcycle/vehicle (45%), building of houses (30%), payment of school fees (21.7%) and marrying wife(es) 1.7%). Perceived environmental impact of charcoal production were air pollution (58.3%), soil infertility/degradation (36.7), deforestation (20%) and poor yield of agricultural crops (16.7%). Respondents were exposed to fire burn (70%), leg injury 46.7%), hand injury (30%), eye related problems (11.7%) and wait pain (3.3%) while they used protective materials like boot (88.3%), eye googles (43.3%) and hand gloves (38.3%)during charcoal production exercise. In conclusion, despite the benefits of charcoal production in Adoka District, the exercise has had adverse impacts on the environment.<#LINE#>Bull, G.

The physico-chemical and bacteriological parameters were determined using standard methods. Twenty Groundwater samples were selectively collected over a period of 6 weeks from two groundwater stations which were Anchor University and Ayobo community. Groundwater temperature values from both well and borehole ranged from 23.9-27.5°C, with an average value of 24.9°C. Conductivity and TDS had their highest values (99.1μS and 49.3ppm) recorded in well 1 of station 1 while in station 2, the result of the selected physico-chemical water quality parameter revealed that the temperature of groundwater samples ranged from 25.1oC to 26.5oC. pH range from 5.0-7.0 with the highest value (7.0) recorded in sample BOK 1 and BOK 2. Conductivity recorded the highest value of 60.9μS while TDS had the highest value of 63.8ppm. Total mean counts for total viable count, faecal coliforms and total coliforms for Station 1 were as follow: 225.00±7.07CFU/ml, 167.00±4.25CFU/ml and 131per 100ml respectively; and for Station 2: 137.00±1.41CFU/ml, 102.00±1.41CFU/ml and 250 per 100ml respectively, which are all higher than the WHO standard limits. The result of the antibiotics susceptibility profiling revealed that the isolates were resistant to more than three antibiotics. In conclusion, this study showed that borehole water and well water around Ayobo are not safe for direct consumption due to high level of the quality indicator bacteria in them.<#LINE#>Rabiu, H.

In this, two passenger vehicles with a universal supply system were studied, and the traction-speed characteristic of the vehicles was determined by the acceleration indicator during the pilot test. Fuel economy characteristics were determined by calculating the distance traveled by the amount of gas fuel in the gas cylinder tank. Also, by adjusting the gas-gasoline modes in the engine to the conditions of operation, the methods of reducing gasoline consumption and thus increasing the environmental safety of the vehicle are mentioned.<#LINE#>Mukhitdinov A.A. and others (2019).@The theory of operational characteristics of the car.@- Jizzakh, 148.@No$Williams, Ian D. and Michael Blyth (2023).@Autogeddon or autoheaven: Environmental and social effects of the automotive industry from launch to present.@Science of The Total Environment, 858, 159987.@Yes$Lv, Z., Wu, L., Ma, C., Sun, L., Peng, J., Yang, L., ... & Mao, H.

The other two river estuaries Damodar and Haldi lie to the north and south respectively of the Rupnarayan which outfall into the Hooghly River. The water of these river estuaries enters and mixes with the water of Rupnarayan River at high tide. Effluents released from Kolaghat thermal power plant and wastewater released from Haldia industrial area mixes with the tidal water of Rupnarayan River which pollutes the river water. Sewage discharges from Haldia, Tamluk and Kolaghat municipalities mixed with the waters of Rupnarayan and became unusable most part of the year. Apart from such pollution, the water of Rupnarayan is now slightly saline for increasing water salinity in the lower reaches of Hooghly River due to sea level rise. Consequent uponthe existence of low salinity in estuarine water, abundant occurrence of giant prawn broods in the confluence has changed the socioeconomic pattern in the localities of three districts surrounding the Rupnarayan River.<#LINE#>Das, G.
