Interactive comment on “Joint Measurements of PM2.5 and light-absorptive PM in woodsmoke-dominated ambient and plume

چکیده
This paper presents analysis that advances understanding of how to potentially assess woodsmoke in air without the need to conduct complex chemical analysis of a woodsmoke marker levoglucosan. It presents mostly useful and straightforward analysis from a study using aethalometers to measure PM2.5 optical absorption under conditions in which mainly woodsmoke is expected. They use this data, along with other measurements to qualitatively and semi-quantitatively assess woodsmoke contribution to PM2.5 levels.

Interactive comment on “Joint Measurements of PM2.5 and light-absorptive PM in woodsmoke-dominated ambient and plume environments” by K. Max Zhang et al
1. "The authors are interested in quantification of the contribution of woodsmoke to PM2.5. Source apportionment always depends on the assumptions of the method employed to determine the sources. The authors make the statement that PM2.5 is dominated by woodsmoke on p. 5 (lines 12-13) and p. 10 (line 14). This should be the result of the work, not an initial assumption, which cannot be tested w...
متن کاملبررسی میزان تماس با ذرات قابل استنشاق (PM2.5) در وسایل نقلیه
Background and purpose: High concentrations of respirable particles may cause high incidence of respiratory diseases and mortality. Epidemiological exposure assessment is based on fixed site measurements in ambient air. However, major studies reported good relationship between indoor fine particulate air concentrations and personal exposure. This study is focussed on personal exposure to PM2....
متن کاملUrinary methoxyphenol biomarkers and woodsmoke exposure: comparisons in rural Guatemala with personal CO and kitchen CO, levoglucosan, and PM2.5.
Urinary methoxyphenols have been proposed as biomarkers for woodsmoke exposure, but few field studies have been undertaken. We evaluated these biomarkers for assessing the exposure to woodsmoke of householders in rural Guatemala. The study population was a subset (10 female cooks, 2 female non-cooks, and 8 male non-cooks ranging in age from 7 to 60) drawn from those participating in a longterm ...
متن کاملPublished Literature on Woodsmoke and Cancer Summary
In human cell lines, woodsmoke caused more DNA damage than traffic-generated PM per unit mass and was found to induce lung cancer in mice. Oncogene mutations in human patients with advanced non-small cell lung cancer were associated with exposure to wood smoke as well as tobacco smoking. Organic extracts of ambient particulate matter containing substantial quantities of woodsmoke were found t...
متن کاملEvaluation of PM2.5 Emissions in Tehran by Means of Remote Sensing and Regression Models
Defined as any substance in the air that may harm humans, animals, vegetation, and materials, air pollution poses a great danger to human health. It has turned into a worldwide problem as well as a huge environmental risk. Recent years have witnessed the increase of air pollution in many cities around the world. Similarly, it has become a big problem in Iran. Although ground-level monitoring ca...
