In recent years, heavy metal concentrations, besides other pollutants, have increased to reach dangerous levels for living environment in many regions. Among the heavy metals lead has the most damaging effects on human health. It can enter a human body through uptake of food (65%), water (20%) and air (15%).&nbsp; With this background certain low cost and easily available biosorbent like <em>Olea Europaea </em>was used and reported in this study. The scope of the present study is to remove Lead from its aqueous solution using <em>Olea Europaea Resin </em>as biosorbent. The Langmuir, Freundlich, Tempkin and Dubinin-Radushkevich (D-R) models were used to describe the biosorption equilibrium of Lead <em>Olea EuropaeaResin</em> biosorbent.The results showed that the biosorption capacity of <em>Olea Europaea Resin</em> biosorbent was more for Lead removal around 34.2 mg/g and the biosorption followed the Langmuir isotherm. The kinetic models showed that the pseudo-second order rate expression was found to represent well with the biosorption data for the biosorbent.</p> 2023-01-02T00:00:00+00:00 ##submission.copyrightStatement## https://journalair.com/index.php/AIR/article/view/929 Biocoagulants as Ecofriendly Alternatives in the Dairy Wastewater Treatment 2023-01-17T12:44:52+00:00 Rakesh Namdeti rakesh.n@sct.edu.om Arlene Joaquin Uma Reddy Meka Muna Amer Ali Azam Al Amri Amal Said Amir Mubarak Kashoub <p>Coagulation is a simple and widely used method for water and wastewater treatment. Chemical coagulants, on the other hand, not only produce vast volumes of toxic sludge, but they also have negative impacts on living organisms. This study demonstrates the use of neem tree leaf and banana leaf powders as natural coagulants for the treatment of dairy effluent. The jar test was used to determine the pH, turbidity, and metal ion content of the treated samples. The biocoagulants were experimented at a rate of 100 mg/L, 200 mg/L, and 300 mg/L at pH of 5, 6, and 7. The levels of turbidity, sodium (Na), potassium (K), calcium (Ca), barium (Ba), lithium (Li), and copper (Cu) were measured after the treatment process. Turbidity was reduced by 52%, and coagulants at 200 mg/L and 300 mg/L were more successful at removing metal ions from dairy effluent except in copper, where 100 mg/L was shown to be more effective. In the scattering between adjacent, similarly charged particles, the zeta potential reveals the strength of repulsive powers. There are more dispersion and suspension rates in the treatment of dairy wastewater using banana and neem leaf biocoagulants. Neem tree leaf and banana leaf powders were efficient and cost-effective eco-friendly biocoagulants for the treatment of dairy effluent.</p> 2023-01-05T00:00:00+00:00 ##submission.copyrightStatement## https://journalair.com/index.php/AIR/article/view/930 Impact of Drought on Sorghum Production and Its Adaptation Strategies in Baki District, Awdal Region, Somaliland 2023-01-17T12:52:33+00:00 Muhiyadin Abdilahi Ali muhiyadinaex.2018@gmail.com Md. Rezaul Karim Mohamed Abdi Osman <p>The main objective of the study was to determine the impact of the drought on sorghum production and its adaptation strategies to overcome the impacts. The sorghum farmers of the Baki and Ruqi villages under the Baki districts were the respondents of the study. the study was conducted from 16 February 2022 – 1 January 2023, from the population, the study selected 109 sample sizes to represent the population by using the Slovin formula with the maximum acceptable error of 5%. The sampling procedure was non-probability particularly purposive sampling. fifteen major drought impacts faced by sorghum farmers were identified in the study. A four-point rating scale was used to measure the extent of drought impact, and based on the scale score, the farmers were categorized. Moreover, Drought Impact Index (DII) was calculated to rank the selected impacts. the highest proportion of sorghum farmers (78 percent) faced high drought impacts on the production of sorghum. Among the 15 selected drought impact the highest drought impact index (DII) was found for ‘Crop failure’ which is (DII 327) and the lowest was “increase the unemployment” with a score of (DII 279). The most prioritized suggestion adaptation strategies regarding the solution of the drought impacts were “Drought-tolerant crop varieties” followed by “Use of short-duration crop varieties” “water harvest for irrigation use”, and “weather forecasts and early warnings system”.&nbsp; The study recommends the adaptation of drought-resistant crop varieties, short-duration crops, the establishment of weather forecasts and early warning systems, and water harvesting for irrigation use to adapt the climatic shocks.</p> 2023-01-17T00:00:00+00:00 ##submission.copyrightStatement##
