ABSTRACT: Iraq is one of the regions most affected by climate change around world. These multidimensional effects and pollution must be taken into consideration when estimating both air pollution-related impacts, in order to develop appropriate health policies measures address current future challenges. The study was conducted Iraqi governorate Salah al-Din, during fall, winter spring seasons y...

Rfn (formaldehyde/nitrogen dioxide) is a common indicator based on satellite observations used to classify ozone formation sensitivity. However, it may underestimate anthropogenic volatile organic compounds (VOCs) in heavily polluted cities when only formaldehyde (HCHO) measure VOCs, since mainly derived from natural sources worldwide. In this study, we multiaxis differential optical absorption...

Abstract. The increasing ozone (O3) pollution and high fraction of secondary organic aerosols (SOA) in fine particle mass has highlighted the importance volatile compounds (VOCs) air control. In this work, four intensive field measurements VOCs during winter 2018 (from 1 December to 17 January 2019), spring (15 April 27 May), summer (17 June 13 July), autumn (22 September November) 2019 were co...

This case study investigates the effects of ventilation intervention on measured and perceived indoor air quality (IAQ) in a repaired school where occupants reported IAQ problems. Occupants' symptoms were suspected to be related to the impurities leaked indoors through the building envelope. The study's aim was to determine whether a positive pressure of 5-7 Pa prevents the infiltration of harm...

Due to the expansion of education industry in Dubai, universities have built many dormitories. Even though Dubai has a robust indoor air quality (IAQ) stipulation for public and educational buildings, dormitories must be included. IAQ newly constructed university can significantly influenced by emissions from furniture made materials such as plywood, medium-density fiberboard (MDF), or particle...

Abstract. Volatile organic compounds (VOCs) are key components of tropospheric chemistry. We investigated ambient VOCs in an industrial area Nanjing, China, between July 2018 and May 2020. The sum the suite measured total VOC (TVOC) concentrations was 59.8 ± 28.6 ppbv (part per billion by volume) during investigation period. About twice TVOC were observed autumn (83 20 ppbv) winter (77.5 16.8 s...
