“…While the internal plant physiological processes of atmospheric NO 2 consumption are known (NO is oxidized to NO 2 in aqueous solutions to deliver NO 2 ; Ghaffari et al, 2005), NO 2 is converted to HNO 3 and HNO 2 in water (Takahashi et al, 2007) and NO − 3 /NO − 2 are metabolized by corresponding reductases to NH + 4 which is incorporated into amino acids (Lea and Miflin, 1974;Yoneyama et al, 2003), possible NO 2 production processes inside plants and are to our knowledge entirely unknown.…”

We describe a dynamic chamber system to determine reactive trace gas exchange fluxes between plants and the atmosphere under laboratory and, with small modifications, also under field conditions. The system allows measurements of the flux density of the reactive NO-NO₂-O₃ triad and additionally of the non-reactive trace gases CO₂ and H₂O. The chambers are made of transparent and chemically inert wall material and do not disturb plant physiology. For NO₂ detection we used a highly NO₂ specific blue light converter coupled to chemiluminescence detection on the photolysis product, NO. Exchange flux densities derived from dynamic chamber measurements are based on very small concentration differences of NO₂ (NO, O₃) between inlet and outlet of the chamber. High accuracy and precision measurements are therefore required, and high instrument sensitivity (limit of detection) and the statistical significance of concentration differences are important for the determination of corresponding exchange flux densities, compensation point concentrations, and deposition velocities. The determination of NO₂ concentrations at sub-ppb levels (<1 ppb) requires a highly sensitive NO/NO₂ analyzer with a lower detection limit (3σ-definition) of 0.3 ppb or better. Deposition velocities and compensation point concentrations were determined by bi-variate weighted linear least-squares fitting regression analysis of the trace gas concentrations, measured at the inlet and outlet of the chamber. Performances of the dynamic chamber system and data analysis are demonstrated by studies of Picea abies L. (Norway Spruce) under field and laboratory conditions. Our laboratory data clearly show that highly significant compensation point concentrations can only be detected if the NO₂ concentration differences were statistically significant and the data were rigorously controlled for this criterion. The results of field experiments demonstrate the need to consider photo-chemical reactions of NO, NO₂, and O₃ inside the chamber for the correct determination of the exchange flux densities, deposition velocities, as well as compensation point concentrations. For spruce NO₂ deposition velocity ranged between 0.07 and 0.42 mm s⁻¹ (per leaf area) and NO₂ compensation point concentration ranged between 0.17 and 0.65 ppb. Under our field conditions NO₂ deposition velocities would have been overestimated up to 80 %, if NO₂ photolysis has not been considered. We also quantified the photolysis component for some previous NO₂ flux measurements. Neglecting photo-chemical reactions may have changed reported NO₂ compensation point concentration by 10 %. However, the effect on NO₂ deposition velocity was much more intense, ranged between 50 and several hundreds percent. Our findings may have consequences for the results from previ...

“…Chlorine oxide anions were identified in photoreaction samples by CE‐ESI‐MS after formation of ion‐pair complexes with the cationic surfactant hexamethonium and their separation by NACE using 2‐propanol/acetone electrolytes 54. Quantification of various inorganic forms of nitrogen, including ammonium, in plant material was feasible by CE‐UV and the results were used to understand the uptake and assimilation of NO 2 55. With the same technique, chlorate, perchlorate, nitrate and nitrite were determined in explosive residues 56.…”

This review article represents the sixth in a series of reviews on CE applied to inorganic analysis, appearing in this journal, and focuses on material published in 2007-2008. As a fundamental review, it examines primarily those documents in which the emphasis is on advances in general CE methodology which are traditionally set on the attainment of higher detection sensitivity and greater preconcentration factors both in capillary and microchip separation formats. Following a major research trend of the previous review period (see A.R. Timerbaev, Electrophoresis 2007, 28, 3420-3425), publications focusing on the quantification of different element species continue to rapidly outpace other applications. A range of practicable separation and detection designs tailor-made to species-selective analysis are critically discussed in order to assess their impact on the rate of development and wide acceptance of CE in the field.
