Access to safe drinking water for the population is of the most vital and important issues in Azerbaijan. Simultaneously, providing the population with clean drinking water is of great important direction for the social and economic development of the Republic. The present study represents the results of similar previous studies on the quality of drinking water in the Binagadi district. According to previous literature, the principal elements of pollution in drinking water are Arsenic, zinc, and copper compounds. The concentration of As, Zn, and Cu has been estimated in the Abseron Peninsula with drinking water. Water supplies were collected in 1 liter of polyethylene bottles, which were washed with deionized water before use. The concentrations of As, Zn, and Cu in the water samples showed that As 3.5-3.7 μg/ l; Cu: 3.6-6.7 μg/l; and Zn 2-9 μg/l, respectively. Also, the concentration showed below but Zn and Cu were higher than the WHO standards permitted limits.

Forty-four specimens of the common torpedo (Torpedo torpedo) were collected from the discarded catch of long-line boat’s haul from Sidi Sha’ab harbor of Tripoli (May 2016) and used for establishing biodiversity and morphometric traits of the fish. The specimens ranged in size from 13.3 to 68.2 cm and in total weight from 92.61 to 989.25 g. The results revealed that the value of the constant b of the length-weight relationship was 1.9064 that indicated negative allometric growth (b< 3). The condition factors of Kf and Kc decreased progressively from 2.54 and 1.82 in the smallest fish size group (17.2 cm) to the largest one (67.5 cm) which recorded a rare value of (Kf = 0.32 and Kc = 0.25), respectively. The length-frequency distribution indicated that the youngest size-group (17.2 cm) peaked at a quarter of the studied samples. Biodiversity and Morphometric traits of the torpedo were related to total length as percentage ratios. Disk length and diameter were larger in females (48.6 and 43.0%) than in males (47.4 and 41.2%).

Climate change especially water stress affects crop productivity in many regions of the world. The current paper assesses the impact of water stress on growth and fruit yield of tomato. Winter cultivar (BARI Tomato-14) was grown under different levels of moisture stress (control, 75, and 50% evapotranspiration moisture) in pot experiment using a randomized complete block design with three replications. The experiment results showed that increased moisture stress progressively reduced plant height (92.73, 90.06, and 75.58 cm), leaf area (198.69, 187.56, and 176.66 cm2), chlorophyll content (47.41, 40.87 and 38.10 mg/g), leaf dry matter (18.07, 16.27, and 12.24%), number of branches (13.55, 12.06 and 10.00) and leaf number (22.93, 22.44, and 20.34) under control 100, 75, and 50% of evapotranspiration conditions, respectively. The result also showed a significant and positive correlation between fruit yield and growth and physiological parameters. The highest correlation was observed between fruit yield and leaf number (r2 = 0.97) followed by chlorophyll content (r2 = 0.95). Consequently, leaf number and chlorophyll content is a suitable index for assessment of water stress and tomato genotypes tolerant.

The provision of environmental sanitation is of great importance to the health status of the people. However, the success may severely depend on the effective access to information and education which are communicated to the public. The purpose of this study is to examine the degree of correlation of demographic factors and environmental sanitation education on an individual’s health status of residents in Maiduguri Metropolis, Borno state of Nigeria. To this aim, the survey design used for this study. The population was selected of all the residents in Maiduguri Metropolis, and 384 respondents were sampled in this study. Descriptive statistics of mean, standard deviation, standard error, frequency count, and percentages were used to organize and describe demographic information while inferential statistics of multiple regressions were used to test the hypothesis at a significance level of 0.05. the results showed that demographic factors and environmental sanitation education correlate with the health status of the residents, in Maiduguri Metropolis in Nigeria.

A method for simulating future rainfall events using improved k-nearest neighbors algorithm (k-NN) used in this study. A simulation day was selected in the month of August. The algorithm steps and resampling with historical data was applied to simulate rainfall events in Kaduna River catchment as a basis for future understanding about the characteristics of the basin. Simulated datasets for the months of April, May, June, July, August, September, and October yielded nearly exact reproduction of the historical data. In the simulation performance, the statistical characteristics such as mean, standard deviation, variance, cumulative probability, covariance, skewness, cross correlation are all preserved by the K-NN model. The results clearly showed that the above Technique can be used for generating future rainfall events that means, it can be used for hydrological investigation about characteristics of a basin for future developments.

This study analyzed the impact of household fuel expenditure as a means of identifying sustainable energy. Secondary data were used obtained from the National Bureau of Statistics (NBS) on a general household survey carried out in 2016. The study employed descriptive statistics, Ordinary Least Squares (OLS), and Consumer Lifestyle Approach (CLA) models. The results revealed that electricity and Liquefied Petroleum Gas )LPG( are the two clean energy sources. However, it was discovered that households dedicate a greater share of their income on dirty fuels. A total of 135,631kg of CO2 is emitted monthly with an average of38kgper household. The urban households were found to emit more CO2than rural households. Furthermore, family size, income, and educational level have a positive effect on CO2emission, while, younger household heads emit less CO2. The Kuznets hypothesis is also found to be applicable to Nigerian households. The present research recommended that the policy of cut one tree and plant five to be reinforced, electricity supply through solar and hydro sources should be improved, the income of the consumer should be augmented and LPG production and supply should also be increased and made affordable to households.

The paper focused on the economic effects of hazardous waste due to oil and gas companies in Rivers State. It include direct, indirect, and induced impacts on jobs, labour income and value addition. Hazardous waste, could be a source of job creation and revenue generation, if properly managed. However, poor management of hazardous waste can cause great danger to environment, plants animals and human life. There are five major waste disposal dumpsites in Port Harcourt metropolis. The present study was restricted to three functioning dump sites at Rumuorlumeni, Igwuruta, and Eliozu. Data were collected from a wide range of subjects to elicit acceptable generalization, and then analyzed and tested in the laboratory. The results showed the p values of the dumpsite dot and parameters measured are significant at 5%, while the p-value of the locations considered is significant at 10%. Hence, there is a significant difference among dumpsite dot parameters measured and the three locations considered. The least squared difference comparison tests were done to identify the significant factors. It showed that the regions where hazardous wastes are dumped are barren due to the presence of heavy metal as they render the soil unfertile to permit crops and plants to germinate and affect on agriculture.
