The samples were subjected to dispersive sol - id-phase extraction (dSPE) using QuEChERS before analysis. Fifteen active substances were detected, including organochlorines, organophosphates, carbamates, ureas, pyrethroids, and others. Three active substances, known for their high toxicity in aquatic environments (carbendazim, malathion, and chlorpyrifos), were identified. The heptachlor molecule (organochlorine family), although banned in Morocco, was still detected in the sediments of the lagoons of Oualidia and Khenifiss. Given the potential harm that these pesticides can cause to living organisms, it is crucial to introduce new crop protection techniques to address this issue.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"3 24","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138625463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To assess VI risks for such a contamination scenario, a comprehensive study was conducted on a factory building located at a trichloroethylene (TCE)-contaminated site. This study involved the integration of various types of field data, including groundwater, bulk soil, soil gas and indoor air data, along with the utilization of the Vapor Intrusion Screening Level (VISL) calculator. Previously observed high TCE concentrations in soil gas are attributed to accumulation of TCE vapor within the unsaturated soil beneath the building floor, since ground surface is extensively paved at this site. These soil gas data do not directly cor - relate with the magnitudes of bulk soil and/or groundwater TCE concentration with the linear adsorption model. Soil gas TCE concentration exceeding 10 7 μg/m 3 (or bulk soil concentration exceeding 18.9 mg/kg) observed in shallow soils (at a depth of less than 1 m ) may pose health risk to the workers inside the building due to VI, as we have detected TCE vapor concentrations exceeding indoor air screening level several times in the past. This bulk soil TCE concentration, however, falls below soil pollution control standards for TCE, i.e., 60 mg/kg, in Taiwan. As a result, soil remediation is not considered at this site. Soil gas TCE concentrations have reduced to less than 10 6 μg/m 3 after two years of groundwater remediation work at this site. However, we have observed significantly higher soil gas TCE levels at a depth of 0.5 m compared to other depths. This discrepancy raises suspicions that an amount of TCE may still be trapped within the shallow soils that are not reached by groundwater table.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"352 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138625920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study is to examine the distribution of microplastics in domestic wastewater, as well as the possibility for microplastic removal in wastewater treatment plants (WWTP). The sampling method used is SNI 6989.59:2008 concerning Wastewater Sampling Methods that Apply in Indonesia. To remove organic compounds in the sample, 0.05 M Fe (II) and 30% H 2 O 2 solution were added by the digestion process at 75 °C for 30 minutes and cooled. Samples were filtered using Whattman GF/C filter paper with the help of a vacuum pump and dried. To identify the concentration, shape, size, color of microplastics, visual analysis was used with the help of a microscope using the zig-zag technique. The concentration of microplastics in domestic wastewater in Gampong Garot is 30.17 ± 0.75 particles/100 mL sample. The most commonly found microplastic size is 1,001–5,000 µm, while the dominant color is transparent. The forms of microplastic found in the samples were fiber, fragments and microbeads with a percentage of 65.20%, 23.16% and 11.64%, respectively. These micro - plastics come from local community activities such as washing clothes, bathing, washing dishes, and other activities. So, it is necessary to treat domestic wastewater using WWTP. Not only does it remove organic matter and nutrients, WWTP also has the potential of microplastics removal around 7–99% depending on the processing unit.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":"106 5","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138607752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The authors suggested the remote-sensing method as a tool for the measurement of the vehicle exhaust emissions and an on-going control thereof. This is an economical solution that allows measuring a large number of vehicles in a short time. The presented work aims at an experimental validation of the measurement method of exhaust emissions on the example of a two-wheeler. To that end, two parallel laboratory tests were carried out: measurement of the exhaust emissions obtained directly from the tailpipe using the PEMS (Portable Emission Measurement System) equipment and from the exhaust cloud, utilizing a module emission gate. A significant mutual correla - tion of the results confirms the efficiency of the method. The highest value of the coefficient of determination was obtained for the CO 2 , PM and NO analyzers. Different orders of values were primarily caused by the dissipation of the exhaust gas and the influence of the ambient conditions on the measurement process. Further works are therefore necessary to allow an assessment of the actual measurement uncertainty of the equipment irrespective of the fueling system and type of vehicles.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":" 1192","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138610213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The role of biochar dose, biochar particle size, reaction time, solution pH, and initial concentration of FC on adsorption efficiency were assessed. The optimum contact time for higher FC uptake was reached after 20 min using NM-B and 8 min using M-B, with a biochar dose of 10 g/L. The optimum pH values and biochar size for higher FC adsorption were 4 and 0.6 mm, respectively. Higher removal was reached at 88% using NM-B and 96% using M-B. The pseudo-second-order model matched well with the kinetic outcomes. Langmuir isotherm was fitted well with the equilibrium results of FC uptake on NM-B and M-B, with regression coefficient (R 2 ) values of 0.98 and 0.998, in that order. The separation parameter was within the limits of favorable adsorption of FC by both biochars. The higher uptake capacity (0.215 mg/g) was linked with the M-B, indicating that chemical modification of biochar was successful in increasing FC uptake from aqueous solutions. This study confirmed that utilizing biochar derived from date palms for FC removal is a very beneficial and cost-effective solution, especially in the countries that are considered the largest date producer in the world.","PeriodicalId":15652,"journal":{"name":"Journal of Ecological Engineering","volume":" 20","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138616497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification of the microorganisms present in indoor air was carried out. The air in the room was sampled before the start of class to determine the “background,” i.e. the concentration level of microbial contaminants in the classroom without the presence of students. Subsequent measurements were taken during teaching activities in the presence of students and the teacher. The study shows that the air condition in the classroom during its opera - tion met the requirements in terms of PM2.5, PM10 and microorganisms. The highest risk was recorded for carbon dioxide. Moreover, the highest recorded readings of this pollutant coincided with the maximum concentrations of the other monitored quantities. Therefore, it can be unequivocally stated that in the case of the analyzed room, monitoring carbon dioxide and adjusting the size of the ventilation airflow to maintain its concentration within the limit of 1000 ppm would guarantee the maintenance of adequate indoor air quality.
