Particulate Matter (PM) and Parent, Nitrated and Oxygenated Polycyclic Aromatic Hydrocarbon (PAH) Emissions of Emulsified Heavy Fuel Oil in Marine Low-Speed Main Engine

Toxics, Journal Year: 2024, Volume and Issue: 12(6), P. 404 - 404

Published: May 31, 2024

To understand the influences of emulsified fuel on ship exhaust emissions more comprehensively, particulate matter (PM), nitrated, oxygenated and parent polycyclic aromatic hydrocarbons (PAHs) were studied a main engine burning heavy oil (EHFO) (HFO) as reference. The results demonstrate that EHFO (emulsified oil) exhibits notable abilities to significantly reduce (PM) low molecular weight PAHs (polycyclic hydrocarbons) in gas phase, particularly showcasing maximum reductions 13.99% 40.5%, respectively. Nevertheless, could increase emission high fine particles pose consequent higher carcinogenic risk for individual particles. total average (gaseous plus particulate) ΣBEQ exhausts (41.5 μg/m

Brominated flame retardants in road dust and green belt soil from Harbin, China: Contamination characteristics, sources and health risks

Environmental Chemistry and Ecotoxicology, Journal Year: 2024, Volume and Issue: 6, P. 229 - 235

Published: Jan. 1, 2024

Brominated flame retardants (BFRs), categorized as persistent organic pollutants (POPs) are difficult to degrade, exhibiting reproductive toxicity and carcinogenicity. Exposure dust soil particles containing BFRs may cause various health problems. The research aimed assess the concentrations, potential origins, risks associated with polybrominated diphenyl ethers (PBDEs) novel (NBFRs) in road green belt Harbin. study revealed that ΣPBDE concentrations ranging from 0.15 193.75 ng/g (median: 48.01 ng/g) 8.07 195.33 38.19 soil. Notably, TBBPA contributed most ΣPBDEs concentrations. And of ΣNBFRs ranged 2.34 130.53 18.48 2.50 46.70 7.85 tetrabromobisphenol A (TBBPA) was dominant compound both samples. Highways exhibited lower samples but higher ΣNBFR compared other roads. Moreover, had a positive correlation each other, suggesting they have similar sources. Principal component analysis (PCA) suggested sources come wire, paint, building materials or commercial products, likewise, household industrial products. Health risk assessment indicated types Harbin no non-carcinogenic residents. These findings provide valuable insights into understanding BFR pollution characteristics, identifying specific sources, recognizing hazards on roads

Mini-review on PAHs in airborne particulate matter: characteristics, sources, and current analytical methods

Review of the Bulgarian Geological Society, Journal Year: 2024, Volume and Issue: 85(1), P. 93 - 99

Published: July 1, 2024

The study of air quality is extreme importance for human health and life, especially in large cities. One the main indicators concentration particulate matter (PM), namely, its composition size. Polycyclic aromatic hydrocarbons (PAHs) are among most dangerous compounds associated with PM because their carcinogenicity mutagenicity, benzo(a)pyrene being analyzed standardized as a priority pollutant. Hundreds PAHs divided into three groups: low, medium, high molecular weight, relative presence gas solid phases determined by properties environmental conditions. emission sources mainly related to low-temperature processes natural anthropogenic origin. analysis both challenge scientific researchers, due low concentrations. attempts focused on development methods that accurate high-resolution, at same time do not require long efforts sample collection, preparation, data interpretation. use various filters, sampling techniques analytical identifying therein, aimed optimizing overall process obtaining reliable results. Data only give information about atmospheric global scale, but also allow pollution appreciate risk population. latter allows take management decisions how improve environment.
