Assessment of Air Pollution,by the Urban Traffic,in University Campus of Bucharest

This study aims to measure traffic-related air pollution of vehicles with internal combustion, the main source of emissions of BTEX, organic compounds and NOx, NO2, NO, O3, CO, SO2, PM10 and PM2.5, inorganic compounds, in three sites of the University campus, surrounded by residential areas. According to the University data, around 8000 students are being exposed daily to the measured level of pollution, in all 3 studied places of campus. A mobile laboratory was used, which continuously measures above mentioned pollutants and mete-orological parameters. The diurnal variation of BTEX, in a sunny and rainy day showed two peaks of BTEX concentration in the morning and evening. In the rainy days, the non-polar (hydrophobic) compounds as BTEX are mechanically trained by rain into the ground, where either they enter into the groundwater, or volatilized and re-enter in the air. Particulate matter such as PM10 and PM2.5 is, in a large part, carried by the rain into the soil. The polar compounds (hydrophilic, NOx, SO2) dissolves in the rainwater and are absorbed in the soil (increasing soil acidity) and evaporated towards the clouds (leading to acid rain). In our study, BTEX compounds removed by the rain varied between 62% - 75%, NOx and SO2, 80% and 77% respectively. Particulate matters were washed out up to 68% for PM10, and 42% for PM2.5. In the sunny days the air pollution with measured concentrations of O3 (121.66 ± 7.02, 123.56 ± 4.89 μg/m3) remained for 7 hours close to the limit value (120 μg/m3). The maximum of solar radiation, with corresponding low concentrations in NOx and xylene, corresponds to photochemical reactions in the atmosphere, generating photochemical smog. In a sunny day and high traffic, we found the maximum value 5.4 μg/m3 for benzene, for 30 min., a known human carcinogen, exceeding the annual limit value de 5 μg/m3. The average background, from benzene, in three University campuses daily visited by around 8000 students was 0.97 μg/m3, exposed to 1.46 μg/m3 and the cancer risk is 1/100,000.

Evidence-based Landscape Design of University Campus:Relationship Between Characteristics of Outdoor Environments and Actual Uses of Students

Several studies have shown a positive relationship between high quality outdoor environments and users’health.Education of agricultural professionals also demands high quality outdoor environments in order to promote students’wellbeing,which in turn supports scientific researches.This study analyzed relationship between students’actual uses and campus outdoor environments,identified what environmental characteristics that students prefered,how they used and why they participated in the outdoor activities.The results could be used as guidance of campus design and management.Investigation of three universities in Harbin provided 686 valid questionnaires.The results suggested that health awareness effectively promoted students’use frequencies of outdoor environments.Environment with"natural"and"cultural"characteristics,especially undulating landform,vibrant plants and landmarks in a serpentins design style attracted more uses.Female students showed more preferences on social interaction activities than males.Students who had good economic consumption levels and participated in outdoor activities frequntly in childhood prefered to join all the kinds of activities after university enrollment.

Peking University Campus:From Ruined Garden to Yan Yuan

The current location of Peking University used to be the campus of Yenching University which was called Yan Yuan. It is situated in the northwestern suburb of Beijing, neighboring the well-known Qing-Dynasty imperial resorts "Summer Palace" and "Fragrant Hill" and the celebrated Tsinghua University.With the naturally endowed landscape, the northwest of Beijing became famous as ideal scenic resorts as early as 800 years ago. During the Ming and Qing dynasties, a cluster of imperial and private gardens were built on the site of

Investigation on occupant presence and appliance operation schedules for university campus in south China sub-tropical area

Building occupant presence during varying periods is crucial to the performance studies of buildings and city regions.However,the understanding of the building occupancies on the university campus remains limited.To address this gap,our study employs field measurements,payment records,course arrangements,and building access systems to depict the occupancy patterns of the canteen,dormitory,library,and teaching and lab buildings during weekdays and weekends.We found that the occupancy rates across different buildings are somehow interrelated,given that the total number of occupants on campus is generally constant.Notably,dormitory occupancy rates tend to be low during the morning and afternoon course hours,which inversely correlates with the high occupancy rates in the teaching and lab buildings during these periods.Similarly,canteens experience surges in occupancy during meal times,which coincide with a decrease in library usage.Moreover,we established appliance operation schedules for dormitories through surveys and on-site investigations.Water dispensers and electronic devices were identified as the primary energy consumers for both male and female occupants,with desk-top fans and hairdryers being significant energy users for male and female occupants,respectively.These findings are essential for energy studies within a campus setting,underlining the importance of considering occupant behaviors on a regional scale.

Mathematical modelling of the spread of COVID-19 on a university campus

In this paper we present a deterministic transmission dynamic compartmental model for the spread of the novel coronavirus on a college campus for the purpose of analyzing strategies to mitigate an outbreak.The goal of this project is to determine and compare the utility of certain containment strategies including gateway testing,surveillance testing,and contact tracing as well as individual level control measures such as mask wearing and social distancing.We modify a standard SEIR-type model to reflect what is currently known about COVID-19.We also modify the model to reflect the population present on a college campus,separating it into students and faculty.This is done in order to capture the expected different contact rates between groups as well as the expected difference in outcomes based on age known for COVID-19.We aim to provide insight into which strategies are most effective,rather than predict exact numbers of infections.We analyze effectiveness by looking at relative changes in the total number of cases as well as the effect a measure has on the estimated basic reproductive number.We find that the total number of infections is most sensitive to parameters relating to student behaviors.We also find that contact tracing can be an effective control strategy when surveillance testing is unavailable.Lastly,we validate the model using data from Villanova University's online COVID-19 Dashboard from Fall 2020 and find good agreement between model and data when superspreader events are incorporated in the model as shocks to the number of infected individuals approximately two weeks after each superspreader event.

Detection of Mercury in Soil and Some Leaf Plants in Campus AL-Mustansaryah University, Baghdad, Iraq

The study was undertaken to assess the extent of mercury contamination in the soil and three types of leaf plants in Campus AL-Mustansaryah University sites within Baghdad, Iraq, as well as to determine the relationship between environmental parameters and the distribution of the mercury contamination with carbon in soil samples were collected and analyzed for inorganic mercury. The highest mercury concentrations were recorded at the sites located lowest cover the plant and close to the diesel-electric generators. Mercury concentrations in leaf plant Ziziphusspina-christi higher concentration than the rest type and soil were mostly higher mercury concentration. Also ratio of carbon to coincide with the increase in the concentration of mercury in the soil of the study areas. Mercury is more biologically because of his preference to bind with carbon. This research confirms that Campus University is key areas for formation of bioavailable mercury distribution is tied to organic carbon.

Individual environmental behavior： A key role in building lowcarbon communities in China

People＇s social behavior, especially environ- mental behavior, has a great impact on energy consump- tion and carbon emission. This paper explores both categories of individual factors （e.g., values, habits, education, motivation, etc.） and social factors （e.g., institution, infrastructure, encouragement, etc.）, to clarify the correlation between them and their sub-factors. Low- carbon campus is a representative type of low-carbon community which is less difficult to build than other communities because university students are well-edu- cated and, to some extent, are more environmental aware and more willing to change their behaviors. The energy- saving and environment-friendly policies implemented on campus are collected and overviewed in this paper. Additionally, the leaders and employees from the related administration departments are interviewed, and the data of electricity amount and water usage are analyzed and a well-designed questionnaire is handed out in a survey. The survey investigates the environmental knowledge, energy use habits, attitude toward low-carbon transformation, comments on the current institution and so on. The results show that different groups of students have varied levels of environmental knowledge, energy use habits, and attitude toward low-carbon campus management. To improve energy conservation and cut carbon emission radically, advices on building low-carbon community are also proposed including professional curriculums of environ- mental protection, economic initiatives, effect manage- ment, good communications, and sound infrastructures and facilities.
