“…the effect of tyre particles, eroded asphalt, lubricating oil leakage and fossil fuels, the concentration of compounds in DD is lower than that of street dust in these cities. However, according to Table S6, the mean concentration of Σ16PAHs was slightly higher or in the same range as some of those obtained from street dusts in tropical and dry areas (Abbasnejad et al 2019, Hassanien &Abdel-Latif 2008, Rastegari Mehr et al 2016.…”

Deposited dust (DD) in urban environments contains carcinogenic organic compounds. The Indoor air quality is greatly affected by heating, ventilation, and air conditioning systems (HVAC), and in the Middle East most of the buildings are equipped by HVAC on top of them. It is possible that the DD on the roof near this equipment would be transferred to an indoor area. For these reasons, 40 samples of the over the roof DD were prepared, and organic compounds (16PAH compounds, 20n-alkane homologs, 8hopanes, and 6steranes) of DD were extracted using Soxhlet and analyzed by GC-MS. Source identification of organic compounds conducted by ring classification, diagnostic ratios, and factor analysis (FA). The results showed that the average (±SD) of total PAHs, n-alkanes, hopanes and steranes in DD were 1356.00 (±291.45) ng kg−1dw, 3211.65 (±969.18), 146.37 (±79.45) and 469.76 (±188.25) µg.g_1dw, respectively. The highest concentration of organic compounds was in the city center, where traffic congestion is common. Diagnostic ratios of n-alkanes results showed the dominant source is vehicular emission. FA results indicated vehicular emission and biogenic sources. In agreement, the results of sterane and hopane profiles confirm these results. On the other hand, the PAHs diagnostic ratios results indicated petroleum combustion sources. In this regard, FA findings showed combustion from vehicular emission and natural gas and wood combustion were the main factors. Furthermore, the incremental lifetime cancer risk was calculated as 8.45× 10−12 for children and 9.80 × 10−7 for adults, and the imposed risk was negligible.

“…The first subgroup consisted of compounds largely found in tyres (Flt, Pyr), while the second subgroup included PAHs typical of pyrogenic sources, e.g. combustion of liquid fuels and biomass/natural gas (Abbasnejad et al, 2019;Ciarkowska et al, 2019;Alves et al, 2020). The third cluster included threering volatile PAHs (Acy and Ace) and DahA, with lower detection frequencies and concentrations compared with other PAHs.…”

“…Factor 1, accounting for 16.3% of total PAHs, was characterised mainly by four-and five-ring PAHs (Flt, Pyr, Chr, BaA, BbF, BkF and BaP), with slight contribution from Flu and Ant. These PAHs are considered to be markers of diesel and natural gas emissions (Hanedar et al, 2014;Abbasnejad et al, 2019). Diesel exhaust consists of Pyr, Flt, BaA and Chr, while other HMW PAHs have lower contributions to this source (Perrone et al, 2014).…”

“…The health impacts of heatwaves typically start from heat cramps, heat exhaustion, dehydration, and heatstroke that later on may lead to death, if necessary, care is not taken. Hence, along with other natural and anthropogenic reasons (Abbasnejad et al 2019;Agarwal et al 2010Agarwal et al , 2013Agarwal et al , 2014Awasthi et al 2017;Panda et al 2020), extreme heat events also play an important reason for the number of causalities throughout the world (Fischer et al 2004;Wang and Yan 2021).…”

The frequency and intensity of extreme events especially heat waves (HW) are growing all around the world which ultimately poses a serious threat to the health of individuals. To quantify the effects of extreme temperature, appropriate information, and the importance of HW and heat index (HI) are carefully discussed for different parts of the world. Varied definitions of the HW and HI formula proposed and used by different countries are carried out systematically continent-wise. Different studies highlighted the number of definitions of HW; however, mostly used Steadman’s formulae, which was developed in the late 1970s, for the calculation of HI that uses surface air temperature and relative humidity as climatic fields. Since then, dramatic changes in climatic conditions have been observed as evident from the ERA5 datasets which need to be addressed; likewise, the definition of HW, which is modified by the researchers as per the geographic conditions. It is evident from the ERA5 data that the temperature has increased by 1–2 °C as compared to the 1980s. There is a threefold increase in the number of heatwave days over most of the continents in the last 40 years. This study will help the researcher community to understand the importance of HW and HI. Furthermore, it opens the scope to develop an equation based on the present scenario keeping in mind the basics of an index as considered by Steadman.
