ABSTRACT Catechol (1,2-benzenediol) is emitted from biomass burning and produced from reaction

34

of phenol with OH radicals. It has been suggested as an important secondary organic aerosol

35

(SOA) precursor, but the mechanisms of gas-phase oxidation and SOA formation have not been

36

investigated in detail. In this study, catechol was reacted with OH and NO3 radicals in the

37

presence of NOx in an environmental chamber to simulate daytime and nighttime chemistry.

38

These reactions produced SOA with exceptionally high mass yields of 1.34 ± 0.20 and 1.50 ±

39

0.20, respectively, reflecting the low volatility and high density of reaction products. The

40

dominant SOA product, 4-nitrocatechol, for which an authentic standard is available, was

41

identified through thermal desorption particle beam mass spectrometry and Fourier transform

42

infrared spectroscopy, and was quantified in filter samples by liquid chromatography using UV

43

detection. Molar yields of 4-nitrocatechol were 0.30 ± 0.03 and 0.91 ± 0.06 for reactions with

44

OH and NO3 radicals, and thermal desorption measurements of volatility indicate that it is semi-

45

volatile at typical atmospheric aerosol loadings, consistent with field studies that have observed

46

it in aerosol particles. Formation of 4-nitrocatechol is initiated by abstraction of a phenolic H-

47

atom by an OH or NO3 radical to form a β-hydroxyphenoxy/o-semiquinone radical, which then

48

reacts with NO2 to form the final product.

INTRODUCTION Biomass burning is a significant source of atmospheric gas- and particle-phase emissions

52

worldwide.1 Biomass burning can be anthropogenic (heating, cooking, prescribed forest fire

53

burns) or natural (lightning propagated wildfires).2 The aerosol emitted from biomass burning

54

can impact regional air quality and regional and global climate through long-range transport,

55

depending on the strength of convection in the plume.3 In addition to the primary organic aerosol

56

(POA) that is directly emitted from wildfires, secondary organic aerosol (SOA) can be formed

57

when emissions of volatile organic compounds (VOCs) are oxidized to condensable products.

58

Field studies have shown mixed results for O3 and aerosol formation in wildfire plumes, with

59

some studies indicating formation and others showing net losses.4-6 Furthermore, POA emissions

60

and SOA production from biomass burning are highly variable and depend on the type of fuel

61

burned.4 These findings show that the mechanisms of SOA formation from wildfire emissions

62

are complex, and may be difficult to model.

63

To date, a number of studies have been conducted to identify and quantify the complex

64

mixture of VOCs emitted from combustion of different types of biomass,7-9 but the fate of these

65

compounds with respect to reactions in the atmosphere and SOA formation is much less certain.

66

In one approach, Gilman et al.9 used their measurements of VOCs emitted from controlled

67

biomass burns with compound-specific SOA formation potentials (derived by Derwent et al.10

68

using the Master Chemical Mechanism11) to estimate total SOA formation potentials for

69

individual compounds and various compound classes. In light of unexplained enhancements and

70

suppressions of O3, and organic aerosol observed in numerous wildfire plumes, however, it is

71

apparent that the chemistry occurring within these plumes needs to be systematically investigated

72

to better constrain the processes leading to these observations.

73

1,2-Benzenediol, commonly known as catechol, is emitted directly from biomass

74

burning12 as well as produced in the atmosphere through the gas-phase reaction of benzene and

75

phenol with OH radicals.13,14 The emission of catechol from wildfires is due to pyrolysis of

76

lignin, a polymer in wood containing phenolic moieties.15 Catechol displays appreciable gas-

77

phase reactivity. Using average concentrations (molecules cm-3) of 2 × 106 (0.1 ppt), 7 × 1011 (30

78

ppb), and 5 × 108 (20 ppt) for OH (12-h daytime), O3 (24-h), and NO3 (12-h nighttime),

79

respectively,16 and corresponding reaction rate constants of 1.0 × 10-10, 9.6 × 10-18, and 9.8 × 10-

80

11

81

studies have shown that catechol produces large quantities of SOA when reacted with O3 and OH

82

radicals,20,21 and it has been predicted to be one of the main precursors to SOA formation from

83

wildfire emissions.9 A study of gas-phase reaction products has shown that under moderate NOx

84

conditions, reaction with OH radicals forms significant amounts of 4-nitrocatechol (4NC),21 and

85

the Master Chemical Mechanism (MCM v3.1) assumes that 4NC is the sole reaction product.11

86

To our knowledge, however, the yield of 4NC has not been measured for reactions of catechol

87

with OH or NO3 radicals in the presence of NOx.

88

cm3 molecule-1 s-1,17-19 estimated atmospheric lifetimes are 1.4 h, 1.7 d, and 20 s. Chamber

In this study, catechol was reacted with OH and NO3 radicals in the presence of NOx to

89

determine yields of SOA and reaction products as well as reaction mechanisms under simulated

90

daytime and nighttime conditions. The vapor pressure of 4NC, the major SOA product in these

91

reactions, was measured for use in predicting its fate and possible environmental impacts.

92

Because of the large catechol emission factors for combustion of biomass,12 and its relatively

93

high predicted SOA formation potential,9 catechol may be responsible for an appreciable portion

94

of the SOA produced from wildfires.

MATERIALS AND METHODS

96

Chemicals. The chemicals used, with purities or solvent grades and supplier were

97

methanol, ethyl acetate, and acetonitrile (HPLC grade, EMD Millipore); water (HPLC grade,

98

Fisher Chemical); catechol (+99%, Sigma Aldrich); 4-nitrocatechol (97%, Sigma Aldrich);

99

glacial acetic acid (99.7%, Macron); dioctyl sebacate (>97%, Fluka); and nitric oxide (99%,

100

Matheson Tri-gas). Methyl nitrite and N2O5 were synthesized according to the procedures of

4

ACS Paragon Plus Environment

Page 4 of 33

Page 5 of 33

Environmental Science & Technology

101

Taylor et al.22 and Atkinson et al,23 respectively. Methyl nitrite was stored in a lecture bottle on a

102

vacuum manifold until used, and N2O5 was stored in a –80°C freezer and placed on a vacuum

103

manifold when used.

104

Environmental Chamber Experiments. Catechol reactions were conducted at 25 °C

105

and 630 Torr in an 8.0 m3 FEP Teflon environmental chamber filled with dry, clean air (RH
100 times more slowly with NO3 radicals.39 Assuming a similar

413

relationship for catechol and 4NC, the lifetimes of 4NC with respect to gas-phase reactions with

414

OH and NO3 radicals are expected to be about 42 h and 30 min. The overall lifetimes are likely

415

to be longer than this, however, since the saturation concentration of 4NC (~13 µg m-3) indicates

416

that it should be present in both the gas and organic particle phases in typical ambient

417

environments, where organic aerosol loadings are ~1–10 µg m-3,51 with a higher fraction in

418

particles near wildfires, where loadings can reach ~100 µg m-3.52 This is consistent with the

419

detection of 4NC and its methylated derivatives in aerosol sampled from biomass burning events

420

during winter at concentrations of 0.1–100 ng m-3, 53–55 with cold temperatures reducing the

18

421

vapor pressure and enhancing gas-to-particle partitioning of 4NC. Furthermore, although the

422

Henry’s Law constant for 4NC has not been reported, by comparing values for phenol, 4-

423

nitrophenol, and catechol (2.8 x 103,56 2.1 x 104,56 and 8.3 x 105 mol L-1 atm-1,57 respectively), it

424

is expected that the value for 4NC will be at least 106 mol L-1 atm-1. The high water solubility of

425

4NC thus allows it to be taken up into aqueous particles,58 which is consistent with its observed

426

presence in rainwater.58 Since a considerable fraction of 4NC should be present in the organic

427

and aqueous phases of aerosol particles, which will reduce the amount available for removal by

428

reaction with OH and NO3 radicals, it is possible that 4NC can undergo long-range transport. It is

429

also worth noting that although this study was concerned with gas-phase reactions of catechol,

430

uptake into aqueous particles containing dissolved H2O2 and iron can lead to Fenton chemistry,59,

431

60

432

can occur in the presence and absence of light suggests that there are additional competing

433

processes to the gas-phase formation of 4NC from reaction of catechol with OH and NO3

434

radicals.

which mainly proceeds by hydroxylation of the ring to produce benzenetriols.59, 60 That this

435

The results from this work can also be used to provide insight into the possible

436

importance of catechol oxidation to SOA formed from biomass burning emissions. Using the

437

SOA yield of 1.34 measured for the reaction of catechol with OH radicals, and an emission ratio

438

of 4 mmol catechol mol-1 CO,9,12 we estimate an organic aerosol enhancement of 23 μg m-3

439

ppmv-1 CO over background concentrations. It should be emphasized, however, that the emission

440

ratio of catechol used in this estimate exhibits large variability between fires, burn conditions,

441

and biomass fuel type.9,12 Also, because the dominant OH radical reaction product, 4NC, is

442

expected to exist less fully in the particle phase in the atmosphere than in the chamber

443

experiments, the SOA yield of 1.34 may be too high. Nonetheless, when compared to POA and

19

ACS Paragon Plus Environment

Environmental Science & Technology

444

SOA concentrations reported for biomass burning field campaigns,1 this estimate suggests that

445

catechol oxidation alone could account for ~10–40% of the organic aerosol mass (see Figure 1B

446

in de Gouw and Jimenez1). This agrees reasonably well with the prediction of Veres et al.,12

447

where catechol emission ratios were measured by burning wood in the laboratory. Furthermore,

448

in a series of wood burning experiments, Bruns et al.61 measured the amounts of VOCs reacted

449

and SOA formed when emissions were reacted with OH radicals generated by photolysis of

450

HONO. By multiplying the amount of VOCs reacted by published SOA yields they estimated

451

that 22 VOCs could account for 84–116% of measured SOA mass, with 8% being due to

452

catechol oxidation. If our measured SOA yield of 1.34 is used instead of the value of 0.39 taken

453

from the literature,62 then catechol oxidation would account for 27% of SOA mass. This may be

454

a more accurate estimate than that of Bruns et al.,61 since the SOA yield of 0.39 was measured

455

for catechol oxidation in the absence of NOx,62 conditions that probably do not represent the

456

chemistry that occurred during their HONO photolysis experiments. Finally, the mechanism of formation and optical properties of 4NC, as well as

457 458

methylnitrocatechols, suggests a possible role for these compounds in O3 formation in biomass

459

burning plumes. Iinuma et al.53 have shown that methylnitrocatechols are produced from the

460

reaction of methylhydroxybenzenes with OH radicals (analogous to formation of 4NC from

461

catechol), but with an estimated molar yield in the aerosol of 0.003, and have suggested them as

462

aerosol tracers of biomass burning. Nitroaromatic compounds are components of brown carbon63,

463

64

464

thus attenuate UV light.66 This attenuation, and the removal of NOx by formation of

465

nitroaromatics, may play a role in the lack of observed O3 formation in some wildfire plumes.6

466

For example, NOx emission ratios average 30 ppbv ppmv-1 CO for pine fuels,67 while catechol

(as shown from the filters in Figure S7 and absorbance measurements by Hinrichs et al.65), and

20

ACS Paragon Plus Environment

Environmental Science & Technology

467

emission ratios can vary from 0.2 – 4 ppbv ppmv-1 CO.9,12 When combined with our results of a

468

30% yield of 4NC from catechol oxidation by OH in the presence of NOx, this suggests that up

469

to 1.2 ppbv [ppmv-1 CO]-1 of NOx could be lost as a result of 4NC formation, representing 4% of

470

emitted NOx. The sequestration of NOx can also occur through formation of peroxyacyl nitrates

471

that can be efficiently formed from alkenes and acetaldehyde, which are all abundant in wildfire

472

smoke.

Uncertainties for catechol concentrations are standard deviations calculated from the duplicate measurements made before and after reaction. Uncertainties in 4NC yield were calculated by propagation of uncertainties in catechol concentration, flow rates for filter sampling, mass measurements, and the 4NC HPLC calibration curve.
