“…These PAHs are toxic, mutagenic, and carcinogenic and hence significantly increase the risk of developing lung cancer [38], [40]. Exposure to heavy metals such as arsenic, lead and nickel is responsible for asthma, emphysema and even lung cancer [41], [42]. Exposure to bioaerosols cause respiratory diseases such as asthma, hay fever, organic dust toxic syndrome, hypersensitivity pneumonitis, and chronic bronchitis [43].…”

Atmospheric aerosols are one of the main pollutants which are harmful to human health and environment. Atmospheric aerosols emitted from different sources are of different sizes and depending upon the size of the aerosol particle, it deposits in different parts of the body and cause varying health problems. Fine Particulate (PM2.5) is associated with more severe health consequences than coarse particulate (PM10) which might be short-term acute symptoms like coughing, shortness of breath, wheezing, respiratory diseases, to more serious problems like asthma, Chronic Obstructive Pulmonary Disease (COPD), bronchitis, pneumonia and long-term chronic irritation and inflammation of the respiratory tract, which may eventually result in lung cancer. Inhalation of ultrafine particles (

“…Based on the proposed system dimensions, it was possible to calculate the capacity of the precipitator, the initial critical field strength, the initial critical voltage, and the radius of the ionization region. The calculated parameters for the precipitation section with a diameter of 120 mm are shown in Table 2 The capacity of the precipitator was calculated according to Equation (1).…”

“…Particulate matter (PM) is a major component of air pollution. Its high concentration negatively affects the cardiovascular system and can lead to respiratory and other diseases that significantly affect the quality and duration of human life [1][2][3]. Although the production of PM emissions is steadily decreasing, especially in the fields of industrial production and transportation, as shown in Figure 1, the field of heating with small heat sources in households is lagging far behind.…”

Design of a Low-Cost Electrostatic Precipitator to Reduce Particulate Matter Emissions from Small Heat Sources

et al. 2022

Capturing particulate matter (PM) is an important issue due to the protection of human health and the quality of their life. This paper describes the innovation of an affordable particulate matter capture device for small heat sources to reduce particulate matter emissions. The design of two investigated variants of the device is based on the principle of a tubular electrostatic precipitator with one charging electrode placed in the chimney. The design of the precipitators is aimed at increasing the area of the collecting electrodes by elements dividing precipitation space, with a simultaneously increased number of charging electrodes. The influence of the elements’ application on the pressure drop and the gas flow velocity through the devices is analyzed by computational fluid dynamics (CFD). The work is further focused on the economic evaluation of precipitators and design adjustments for lower energy consumption. The achieved results show the right direction of efforts to improve the equipment designed to capture PM emissions.

“…Common chemical constituents of PM include sulfate, nitrate, organic and elemental carbon, organic compounds, biological compounds, and heavy metals ( 8 ). Numerous scientific studies have shown that PM toxicity is linked to various respiratory diseases, such as asthma, COPD, idiopathic pulmonary fibrosis, and lung cancer ( 9 - 12 ).…”

Background In recent years, ambient particulate matter (PM) exposure has been strongly linked with health effects. Elevated levels of PM in polluted air have been correlated with the onset and development of chronic obstructive pulmonary disease (COPD). This systematic review was conducted to evaluate biomarkers that could reflect the effects of PM exposure in patients with COPD. Methods We performed a systematic review of studies published on biomarkers associated with PM exposure in patients with COPD between January 01, 2012 and June 30, 2022 in PubMed/MEDLINE, EMBASE, and Cochrane databases. Studies that included data on biomarkers with COPD exposed PM were eligible for inclusion. Biomarkers were classified into 4 groups according to their mechanisms. Results Of the 105 studies identified, 22 were included in this study. Nearly 50 biomarkers have been proposed in the studies included in this review, and the most studied in relation to PM are several interleukins. Various mechanisms have been reported by which PM induces and aggravates COPD. Six studies related to oxidative stress, one related to direct effect of innate and adaptive immune systems, 16 associated with genetic regulation of inflammation, and two related to epigenetic regulation of physiology and susceptibility were found. Biomarkers related to these mechanisms were detected in serum, sputum, urine, exhaled breath concentration (EBC), and showed various correlations with PM in COPD. Conclusions Various biomarkers have shown potential in predicting the extent of PM exposure in COPD patients. Future studies are needed to establish recommendations for regulation to reduce airborne PM, which could be used to develop strategies for prevention and management of environmental respiratory diseases.
