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...

The analysis of heavy metal concentrations and forms in sewage sludge constitutes an important issue terms both health environmental hazards the metals pose. total concentration enables only assessment its contamination. Hence knowledge chemical is required to determine their mobility final disposal. Heavy speciation was studied by using four-stage sequential extraction BCR (Community Bureau Reference). This study aimed at determining selected (Zn, Cu, Ni, Pb, Cd, Cr Hg) (except for...

The manuscript presents an innovative and holistic approach to quantifying PAHs BTEX emissions from the grilling process indicates a novel driven-toxicity-based solution recognize health effects related BBQ emissions. exposure scenario includes type of device, food type, individual attitudes, but also keen understanding broad implications gaseous/particulate emission, or age-related effects. calculated incremental lifetime cancer risk (ILCR) associated with PAH congeners unacceptable level...

This study evaluates the quality of 30 biomass pellets sold for residential use in Poland. It provides data on their physical, chemical, and petrographic properties compares them to existing standards information provided by fuel producers. The results reveal considerable variations show that some purchased samples are not within DINplus and/or ENplus certification thresholds. Among all samples, only one passes thresholds set PL-US BIO, a newly established Poland combines assessment...

Abstract This study aimed to assess the potential risks posed by heavy metals in sewage sludge (SS) produced municipal wastewater treatment plants (WWTPs) most industrialized region Poland, Silesian Voivodeship. The ecological risk was assessed using three indices: Geoaccumulation Index ( I geo ), Potential Ecological Risk Factor (ER), and Assessment Code (RAC), while health estimated carcinogenic non-carcinogenic indices. average concentrations of samples were determined revealing that Zn...

Lung cancer is the leading cause of occurrence around world. When exploring geographic distribution in lung incidence Poland, we found that PM10-bound benzo(a)pyrene (B(a)P) emission from domestic heating contributes to risk mostly areas outside cities and agglomerations (so-called remaining areas). averaging B(a)P concentrations within provinces, exposure accounts for even 31% total cases. To check which extent concentration could contribute an increase probability occurrence, analysis...

Air pollution by particulate matter (PM) is recognized as a one of the most important environmental issue. A particular attention being paid to fine PM fraction (PM2.5, PM1.0) due its detrimental impact on human health and long-term persistence in air. Presented work an in-depth bibliometric study concentrations chemical composition PM2.5 among 27 rural 38 urban/urban background stations dispersed across Europe. Obtained results indicate that PM2.5, terms mass percentage contribution main...

Abstract Aerosol water is a master component of atmospheric aerosols and medium that enables all aqueous-phase reactions occurring in the atmosphere. This integral chemical compound suspended aerosol particles (PM) has become one hottest issues recent years. To look for scientific productivity area PM-bound research bibliometric analysis was performed. Most actual literature regarding particulate bound implications this field downloaded from WOS database using 1996–2018 timespan. Different...

In this study, the occurrence, fractionation, and potential ecological risk associated with seven heavy metals (HMs), i.e., Cd, Cr, Cu, Ni, Pb, Zn Hg in sewage sludge (SS) were investigated. The main aim of study was to conduct first comprehensive analysis HMs SS collected from two municipal wastewater treatment plants (WWTPs) using ultrasonic disintegration (UD) thickened excess aimed at improving effects anaerobic digestion (AD). order assess level risk, groups indices related total...

Genotoxic assessment of landfill leachate before and after biological treatment was conducted with two human cell lines (Me45 NHDF) Daphnia magna somatic cells. The alkali version comet assay used to examine genotoxicity by DNA strand breaks analysis its repair dynamics. samples were collected from Zabrze landfill, situated in the Upper Silesian Industrial District, Poland. Statistically significant differences (Kruskal-Wallice ANOVA rank model) observed between cells incubated (<mml:math...

The purpose of this study was to determine the heavy metal (HM: Cd, Cr, Cu, Ni, Pb, Zn, and Hg) content in particular chemical fractions (forms) sewage sludge with different characteristics (primary dewatered sludge) using conventional (CSE) ultrasound-assisted (USE) BCR sequential extraction methods (Community Bureau Reference, now Standards, Measurements Testing Programme). concentrations HMs were determined inductively coupled plasma optical spectrometry (ICP-OES). Only mercury assayed...

This study assessed inhalation exposure to particulate matter (PM1)-bound mercury (Hgp) and PM1-bound polycyclic aromatic hydrocarbons (PAHs) among university students. For this purpose, simultaneous indoor (I) outdoor (O) measurements were taken from two Polish technical universities (in Gliwice Warsaw) located in distinct areas with respect ambient concentrations major sources of PM. The geometric mean Hgp found be 1.46 pg·m−3 6.38 Warsaw Gliwice, while the corresponding slightly lower at...
