Abstract. Since the publication of compilation biomass burning emission factors by Andreae and Merlet (2001), a large number studies have greatly expanded amount available data on emissions from various types burning. Using essentially same methodology as this paper presents an updated factors. The over 370 published were critically evaluated integrated into consistent format. Several new categories added, species for which are presented was increased 93 to 121. Where field still insufficient, estimates based appropriate extrapolation techniques proposed. For key species, compared with previously values. Based these global activity estimates, I derived pyrogenic important released

Indoor air pollution (IAP) is a serious threat to human health, causing millions of deaths each year. A plethora pollutants can result in IAP; therefore, it very important identify their main sources and concentrations devise strategies for the control enhancement indoor quality (IAQ). Herein, we provide critical review evaluation major pollutant emissions, health effects, issues related IAP-based illnesses, including sick building syndrome (SBS) building-related illness (BRI). In addition, approaches reduction are pointed out, recent trends efforts resolve improve IAQ, with respective advantages potentials, summarized. It predicted that development novel materials sensors, IAQ-monitoring systems, smart homes promising strategy IAQ future.

Recent Insights into Particulate Matter (PM2.5)-Mediated Toxicity in Humans: An Overview

International Journal of Environmental Research and Public Health, Journal Year: 2022, Volume and Issue: 19(12), P. 7511 - 7511

Published: June 19, 2022

Several epidemiologic and toxicological studies have commonly viewed ambient fine particulate matter (PM2.5), defined as particles having an aerodynamic diameter of less than 2.5 µm, a significant potential danger to human health. PM2.5 is mostly absorbed through the respiratory system, where it can infiltrate lung alveoli reach bloodstream. In reactive oxygen or nitrogen species (ROS, RNS) oxidative stress stimulate generation mediators pulmonary inflammation begin promote numerous illnesses. According most recent data, matter, PM2.5, responsible for nearly 4 million deaths globally from cardiopulmonary illnesses such heart disease, infections, chronic cancers, preterm births, other There has been increased worry in years about negative impacts this worldwide danger. The causal associations between health, toxic effects mechanisms molecular pathways described review.

Real-time sensing of bioaerosols: Review and current perspectives

Aerosol Science and Technology, Journal Year: 2019, Volume and Issue: 54(5), P. 465 - 495

Published: Sept. 12, 2019

Detection of bioaerosols, or primary biological aerosol particles (PBAPs), has become increasingly important for a wide variety research communities and scientific questions. In particular, real-time (RT) techniques autonomous, online detection characterization PBAP properties in both outdoor indoor environments are becoming more commonplace have opened avenues research. With advances technology, however, come challenges to standardize practices so that results reliable comparable across technologies users. Here, we present critical review major RT instrument classes been applied research, especially with respect environmental science, allergy monitoring, agriculture, public health, national security. Eight covered, including the following: (i) fluorescence spectroscopy, (ii) elastic scattering, microscopy, holography, (iii) Raman (iv) mass spectrometry, (v) breakdown (vi) remote sensing, (vii) microfluidic techniques, (viii) paired aqueous techniques. For each class technology technical limitations, misconceptions, pitfalls, also summarize best operation, analysis, reporting. The final section article presents pressing questions grand sensing as well recommendations future work encourage high-quality increased cross-community collaboration.

Anthropogenic enhancements to production of highly oxygenated molecules from autoxidation

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(14), P. 6641 - 6646

Published: March 18, 2019

Atmospheric oxidation of natural and anthropogenic volatile organic compounds (VOCs) leads to secondary aerosol (SOA), which constitutes a major often dominant component atmospheric fine particulate matter (PM2.5). Recent work demonstrates that rapid autoxidation peroxy radicals (RO2) formed during VOC results in highly oxygenated molecules (HOM) efficiently form SOA. As NOx emissions decrease, the chemical regime atmosphere changes one RO2 becomes increasingly important, potentially increasing PM2.5, while oxidant availability driving formation rates simultaneously declines, possibly slowing regional PM2.5 formation. Using suite situ aircraft observations laboratory studies HOM, together with detailed molecular mechanism, we show although an archetypal biogenic system more competitive as decreases, absolute HOM production decrease due reductions, leading overall positive coupling between localized SOA from autoxidation. This effect is observed Atlanta, Georgia, urban plume where enhanced presence elevated NO, predictions for Guangzhou, China, HOM-RO2 coincides increases NO 1990 2010. These suggest added benefits abatement strategies come emission reductions have implications aerosol-climate interactions global resulting since preindustrial era.

Abstract Fine particle pollution, PM 2.5 , is associated with increased risk of death from cardiorespiratory diseases. A multidecadal shift in the United States (U.S.) composition towards organic aerosol as well advances predictive algorithms for secondary (SOA) allows novel examinations role components on mortality.
