Indoor Air Quality, Health Effects Resulting from Coffee Shops Smoke – Review Ghayda Al Kindi, Husam Al‑Haidri Ecological Engineering and Environmental Technology, 2023 All over the world, people are drawn to stay most of their time in indoor environments and largely in restaurants and cafes. For this reason, the aim of this study is to provide information to decision-makers and researchers about indoor air pollution in cafes and its significant impact on people’s health. Cigarettes, hookahs, and electronic cigarettes abound in cafes frequented by young people (Most of them are school students) and some women, In addition, to minors. The main sources of pollutants in coffee shops are heating, cooling, cooking, and emissions from shisha, cigarettes, and e-cigarettes. The most common pollutants are CO, PMs, NOx, SOx, and VOCs, in addition to nicotine. Health effects appear in adults, children, and women, they affect otitis media, and heart disease for children, while it is on heart attack, nasal irritation, lung cancer, and coronary heart disease. As for its effects on the pregnant woman and the fetus, it affects reproduction and low birth weight. This review could be for environmental legislators for Iraqis, in international organizations to formulate legislation for indoor air for cafes that takes into account all sources of air pollution to create a healthy and comfortable environment. The review is also useful for cafe managers and customers to understand the potential health risks of indoor air pollution.
Adsorption, Isotherms, and Kinetics for Phenol Removal on Biochar Prepared from Wheat Husk Marwa F Al Rawi, Ghayda Yaseen Al Kindi, Jwad Kadham Al Refaae, Tariq Abed Hussain, Husam A. Al-Haidri Iop Conference Series Earth and Environmental Science, 2023 In this study, wheat husks were transformed into biochar (BCs). It has been used to remove phenol from the wastewater. BCs it was prepared by hydrothermal carbonization and after activation with H3PO4 Therapy. the Tube furnace were used for carbonization. many examinations were used to study the BC properties such as Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET). in batch reactor, the operation condition were studied by many parameter in different dose, such as (pH, doses of BC and phenol ). also, to determine maximum removal efficiency of phenol on biochar. From results the best operating condition were pH and contact time 4, 1 hr, the BC dose 0.5 g / L, and 50mg/L for phenol dose. with constant for others parameters such as (agitation velocity of 150 rpm, ambient temperature, and initial phenol concentration 50 mg /L). the maximum removal efficiency for phenol reach to (84%). the second order was the best adsorption kinetic. Freundlich isotherm model has introduced a fair description for sorption, so, the BC could be utilized effectively as an adsorbent.
The nanoparticles zero-valent synthesis by black tea extract to remove rb 238 using synthetic and natural wastewater by packed bed reactor Ghayda Y. Al Kindi, Ahmed K. Hassan, Dalal GH Yahya, Husam A. Alhaidri Iop Conference Series Earth and Environmental Science, 2021 This study aims to synthesize nanoparticles of iron zero valences from black tea (BT-NZVI) and bentonite supported with black tea zero-valent iron (B-BT-NZVI) using black tea extract in an environmentally friendly and sustainable way to remove the reactive blue pigment 238 (RB). 238) from water. The characterization tests for BT-NZVI and B-BT-NZVI were performed by atomic force microscopy (AFM) and scanning electron microscopy (SEM). The zeta potential in the stability of iron nanoparticles was also measured. For measuring the porous material’s surface area, the Brunaune Emmett-Teller (BET) method was used the average diameter of iron nanoparticles was less than 50 nm. BT-NZVI and B-BT-NZVI were used as absorbents in the batch system study. Two adsorption balance models, Langmuir and Freundlich, are used to describe the adsorption process. The Freundlich model matches well with Reactive Blue 238 dye data and has proven successful in the adsorption process. Kinetic data acquired using the pseudo-first and pseudo-second model examined under optimal reaction conditions and a variety of NZVI concentrations. both batch and up-flow packed flow bed reactor with peroxide H2O2 can degrade dyes and utilized in industrial wastewater treatment.
Diclofenac removal from wastewater by activated carbon Ghayda Y. AL-Kindi, Faris H. AL Ani, Noor Kh Al-Bidri, Husam A. Alhaidri Iop Conference Series Earth and Environmental Science, 2021 Pharmaceuticals have been widely found in wastewater. Among them, diclofenac was detected at the highest frequency; in this study, the commercial activated carbon was used to remove diclofenac from synthetic wastewater. Various testing methods were applied to evaluate the efficiency of the activated carbon for removing diclofenac from residues wastewater such as scanning electron microscopy (SEM), Brunauer, Emmett and Teller (BET), and Energy Dispersive Spectroscopy (EDS). the operating conditions were determined by using a batch reactor with various parameters such as different pH, diclofenac concentration, and different mass of activated carbon. the result of operations conditions was: pH 5, diclofenac concentration is 1000 mg/l mass of activated carbon is 500gm/L, While, the difference of initial Ibuprofen concentration, flow rate, and bed depth was determined by packed bed reactor, it was found 2cm for bed height, and flow rate 25 l/hr, Diclofenac concentration, 625mg/l. from adsorption equilibrium and with Langmuir and Freundlich models, the kinetic constants were determined, also shown the pseudo-first-order gave the best result, and more suitable for the removal of Diclofenac by adsorbed activation carbon.
The Removal of Ibuprofen Drugs Residues from Municipal Wastewater by Moringa Oleifera Seeds Ghayda Al-Kindi, Husam Al Haidari Journal of Ecological Engineering, 2020 Municipal wastewater may contain residues of different drugs causing severe chemical contamination of water bodies. However, the microbial degradation of Wastewater Treatment Plants (WWTP) may not eliminate such drug residues completely. The current work was designed to remove the Ibuprofen drug residues by using the Moringa Oleifera seeds. Various testing methods such as Brunauer, Emmett and Teller (BET), Transmission Electron Microscopy (TEM), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR) were applied to assess the efficiency of such plant seeds in bioremoval of ibuprofen residues from municipal wastewater The batch reactor was used to find the optimum operating conditions using various parameters with different pH values, duration time, Ibuprofen concentration and various quantities of plant seeds. In the batch reactor, the operation conditions were: pH 7, duration time 150 min, Ibuprofen dose of 1000 mg/l, activated adsorbents and Moringa Oleifera seeds in the amount of 1000 mg/l. Moreover, the packed bed reactor was used to examine different parameters such as initial Ibuprofen concentration, flow rate and bed depth for 6 hours. It was found that the best conditions were 2 cm depth, and 25 l/hr flow rate. Meanwhile, the kinetic constants were studied by adsorption equilibrium with the isothermal Langmuir and Freundlich models. The best results were shown with the Freundlich isotherm, and the first pseudo order was more suitable for the removal of Ibuprofen by adsorbed activation of Moringa Oleifera seeds.
