Indoor air quality is of major concern for human health and well-being. Nitrous acid (HONO)
is an emerging indoor pollutant, and its indoor mixing ratios are usually higher than outdoor …

Gaseous nitrous acid (HONO) is a critical source of hydroxyl radicals (OH) in the
troposphere. While both direct and secondary sources contribute to atmospheric HONO …

As primary emissions have been declining in recent decades in China, secondary pollution,
like ozone (O 3) and secondary aerosols are main pollutants deteriorating air quality. The …

Vehicular emissions are an important source for volatile organic compounds (VOCs) in
urban and downwind regions. In this study, we conducted a chassis dynamometer study to …

Nitrous acid (HONO) is an important source of hydroxyl radicals (OH) in the atmosphere.
Precise determination of the absolute ultraviolet (UV) absorption cross section of gaseous …

Co-occurrences of high concentrations of PM 2.5 and ozone (O 3) have been frequently
observed in haze aggravating processes in the North China Plain (NCP) over the past few …

HONO acts as a major OH source, playing a vital role in secondary pollutant formation to
deteriorate regional air quality. Strong unknown sources of daytime HONO have been …

Nitrous acid (HONO) is an important photochemical precursor to hydroxyl radicals
particularly in an urban atmosphere, yet its primary emission and secondary production are …

Nitrous acid (HONO), a key precursor of hydroxyl radicals (OH), is one of the factors affecting
atmospheric chemistry and air quality. Currently, the proposed sources of HONO are not …

HONO concentrations in Bei**g (BJ) and Sanmenxia (SMX) were simultaneously measured
in winter with a duration of 1 month, and the sources and sinks of HONO in the two cities …
