Twenty subjects with mild asthma were exposed at rest in a body plethysmograph, to NO2 at 0, 260, 510 and 1,000 micrograms.m3, for 30 min on four separate days. Bronchial responsiveness (histamine inhalation test) was measured after each exposure session. Airway resistance (Raw), thoracic gas volume (TGV) and specific airway resistance (sRaw) were measured before, during and after exposure, and...

The effect of elevated level of SO2+NO2 on some physiological and biochemical parameters of Glycine max were examined. Twelve days olds Soybean (Glycine max) seedling were exposed to two different (2% and 3%) levels of SO2+NO2 mixture. Fumigants were applied for 30 minutes per day, 3 days per week for 3 weeks duration. Aeration with enriched SO2+NO2 air resulted in higher phenolic content as co...

CuO nanowires (NWs) were grown by the thermal oxidation of Cu foil at 400 ◦C and gas sensors were fabricated by the deposition of a solution containing the CuO NWs. At 300–370 ◦C, the sensor resistance increased upon exposure to 30–100ppm CO. This has been explained by the gas sensing characteristics of the p-type oxide semiconductor. In contrast, the sensor showed two opposite NO2 sensing beha...

Nitric oxide (NO) in oxygen-containing aqueous solution has a short half-life that is often attributed to a rapid oxidation to both NO2- and NO3-. The chemical fate of NO in aqueous solution is often assumed to be the same as that in air, where NO is oxidized to NO2 followed by dimerization to N2O4. Water then reacts with N2O4 to form both NO2- and NO3-. We report here that NO in aqueous soluti...

[1] The role of nitrous acid, HONO, as a precursor for hydroxyl radicals in polluted urban air has been recognized for many years. The chemical processes leading to the formation of HONO are, however, still not well understood. Laboratory studies show that HONO formation occurs primarily on surfaces and is first order in NO2. Water also plays an important role in the conversion process. While t...

CONTEXT There is a relative lack of studies about exhaled nitrite (NO2-) concentrations in cirrhotic and transplanted patients. OBJECTIVE Verify possible differences and correlations between the levels of NO2-, measured in plasma and exhaled breath condensate collected from patients with cirrhosis and liver transplant. METHOD Sixty adult male patients, aged between 27 and 67 years, were sub...
