The distribution of mass and the number particles is a determining factor in respirable nature given particulate matter (PM), thus potential health effects breathing air question. One most popular activities during summer months preparation food on barbecue. Barbecuing represents one few sources combustion particulates summer, period which otherwise characterised by lack heating. objective this study to ascertain fractional composition PM emitted an electric barbecue compare these values with measured background. concentrations (PM) at were determined Palas AQ Guard optical spectrometer, while background Fidas 200 spectrometer that complies EN16450 standard. contribution individual fractions environment differed from observed ambient air. measurements exhibited relatively well-defined consistent distribution, PM1 fraction representing between 10 30% PM4−1 accounting for only 20%. Thus, PM4 did not exceed 50% total particles. Upon analysis grilling process, it was capable substantial proportion, exceeding 90% mass. trend related maintained; however, limit maximum content increased 40% PM. results demonstrate process itself, utilising without emission fuel, can exert notable influence submicron

Contaminants of emerging concern such as organophosphate flame retardants (OPFRs) are associated with atmospheric fine particles (PM2.5), which pose the greatest health risk in world. However, few surveys have explored interaction between PM2.5 and OPFRs residential paired indoor/outdoor environments. 11 priority were investigated across 178 indoor outdoor air samples taken from 89 children's households southern Taiwan, cold warm seasons. This involved exploring their associations building characteristics, interior materials, human activities. We developed a probabilistic predictive model for based on (I/O) ratio contaminants an quality index. The significant explored. level was greater than that households, contrasting PM2.5. I/O higher 1 (except TEHP, EHDPP, TCP), suggests sources primarily emitted indoors. Indoor TCEP significantly positively OPFR detected apartments houses due to decoration, furniture electronic devices. this not case TCIPP dominant compound air. obtained high accuracy R2 value 0.87. material used mattresses, use purifiers heaters, total area main influencing factors households. These findings could provide important evidence equipment different types. In addition, it prevent potential risks posed by pollutants eliminate emissions through selection better construction materials.

Quantifying the impacts of reduction strategies on PM2.5-bound polycyclic aromatic hydrocarbons (PAHs) is essential for reducing health risks PM2.5. The COVID-19 lockdown provided an opportunity to reveal quantitative relationship between measures and PAHs. In this study, characteristics, sources, PAHs were investigated during in Hohhot. source-specific assessed using a combination incremental lifetime cancer risk models (ILCR) positive matrix factorization (PMF). Compared with pre-LD period (pre-LD, 87.41 ± 5.98 ng·m-3), total concentration ∑PAHs (LD, 32.52 2.31 ng·m-3) decreased by 62.8% Coal combustion (51.5%), gasoline emissions (21.9%), diesel (12.9%), industrial (9.3%), biomass burning (4.7%) predominant sources Except male children, ILCR all groups exceeded threshold high (1 × 10− 4).

Cooking oil fumes are full of dangerous chemicals that bad for human health. Volatile organic compounds (VOCs) in cooking not only emitted the form gas but may also accumulate with other substances and particulate matter into atmosphere. Different forms VOCs can enter different regions body have varying effects on This paper investigated VOC emission types found some fumes. The findings demonstrate contaminants from edible oils were released as particle matter, being predominant component. fraction gaseous steadily declined temperature rose, whereas proportion gradually rose. It is possible to assume increase fume was caused by original oil’s components volatilizing more frequently under influence vapor pressure chemical reactions primary cause creation.
