Elements in Fine Particulate Matter (PM $$_{2.5}$$ 2.5 ) from Indoor Air During Household Stoves Coal Combustion at Xuanwei, China

Abstract

The characteristics of elements in fine particulate matter (PM 2:5 ) emitted during indoor coal combustion in Xuanwei were investigated. Lead (Pb) emissions were high among the trace elements at all sampling locations. The average Pb concentrations in ''Laibin'' samples were $ 1.5 time higher than ''non-Laibin'' samples and were statistically significantly difference (paired t test). Concentration ratios normalized to total suspended particles for the elements were also characterized and compared between the two types of locations. Element ratio (Se/S) values were different with another study, suggesting possible different composition characteristics of the samples in Xuanwei compared with other regions in China. These findings provide information about concentrations of elements in different types of coal samples emission during household coal combustion. There is a need to address the health effects of environmentally relevant doses of elements in fine particulate matter, considering life-long exposure of people in indoor dwellings.

Polycyclic aromatic hydrocarbons accumulation in soil horizons of different temperate forest stands

“…Polycyclic aromatic hydrocarbons (PAHs) are organic compounds comprising two or more interconnected benzene rings and are known to contaminate soil environments (Cao et al, 2020; Ghosal et al, 2016; Sun et al, 2012). The prevalence of PAHs in the soil is mostly of anthropogenic origin (Zhou et al, 2005) due to the increasing use of energy from the combustion of fossil fuels, oil and internal combustion engines (Lui et al, 2017; Tiwari et al, 2011). Atmospheric PAHs accumulate easily in the soil due to their sorption capacity (Eom et al, 2007; Kováts et al, 2021) and arrive at the land surface through both wet and dry deposition (Choi et al, 2009; Ding et al, 2007).…”

Marmara Üniversitesi Prof. Dr. Orhan Oğuz Kütüphanesi’nde Element Konsantrasyonları

“…Bilimsel literatürde özellikle üniversite binalarında iç hava kalitesi ve metal konsantrasyonlarını inceleyen bilimsel çalışmalar [4,5,6,7,8] yoğunlıkta iken, genel olarak element konsantrasyonları okul binalarında [9,10,11,12,13,14,15,16,17] bilimsel ağırlıklı olarak incelenmiştir. Ofislerin element konsantrasyonlarını inceleyen bilimsel çalışmalar [18], genel olarak atmosferik çalışmalar [19,20,21,22,23] araştırmacılar tarafından bilimsel olarak incelenmiş ve element konstrasyonları ölçüm sonuçları değerlendirilmiştir. Özellikle insan sağlığı açısından risk oluşturan ve ağır metal konsantrasyonu ifade eden iç hava kalitesi ile ilgili bilimsel çalışmalar Tan ve Kurt-Karakus [2,21]tarafından incelenmiştir.…”

Ecological Risk Assessment, Distribution and Source of Polycyclic Aromatic Hydrocarbons in the Soil of Urban and Suburban Forest Areas of Southern Poland

“…They occur in aspects of the environment, such as the air, water, soil, and living organisms, which is related to their formation through the processes of incomplete combustion of organic substances. The majority of these compounds come from anthropogenic sources such as industrial processes related to the combustion of crude oil and coal, room heating, road transport and the incineration of municipal and industrial waste [6,7]. PAHs demonstrate high durability and stability in various environmental conditions [8].…”
