Influence of rice growth on the fate of polycyclic aromatic hydrocarbons in a subtropical paddy field: A life cycle study

“…Plant roots can evidently degrade or take up SVOCs from the soil (Su and Zhu, 2008;Gao et al, 2010;Ma et al, 2012), while the foliage can efficiently filter or capture both vapor and particle phases of SVOCs in the air (Su et al, 2007;Choi et al, 2008;Li et al, 2009;Moeckel et al, 2009;Wang et al, 2012). This so-called ''filter effect'', which can significantly increases the air-to-soil flux of SVOCs, has been well characterized in a forest ecosystem (Terzaghi et al, 2013).…”

“…Paddy ecosystems have received much attention recently, not only because of food safety concerns, but also because of their potential ecological functions such as phytoremediation (Li et al, 2009;Gao et al, 2010;Ma et al, 2012). However, most previous studies (Su and Zhu, 2008;Li et al, 2009) on the bioremediation potential of rice have been conducted using pots or focused on only one or two environmental matrices; few studies have comprehensively examined the environmental fate of PAHs in a rice paddy ecosystem throughout an entire growing season. The purpose of the present study was to systematically investigate the influence of rice growth on the behavior and fate of PAHs in a subtropical paddy field.…”

Total oxidation of naphthalene with high selectivity using a ceria catalyst prepared by a combustion method employing ethylene glycol

“…In particular, the release of polycyclic aromatic hydrocarbons (PAHs) has started to cause considerable concern. The main source of these atmospheric pollutants is the combustion of fossil and non fossil fuels, such as diesel, gasoline, biomass, coal and wood [11][12][13][14]. The emission of PAHs from diesel vehicles is becoming more and more important due to the progressive worldwide substitution of gasoline fuelled vehicles by those that use diesel.…”

The effects of rice canopy on the air–soil exchange of polycyclic aromatic hydrocarbons and organochlorine pesticides using paired passive air samplers

“…Plant uptake and degradation of SVOCs have been well characterized, especially for vegetables (Mueller et al, 2006;Huang et al, 2010) and crops (Lin et al, 2007;Su and Zhu, 2008). Plants can also act as filters of atmospheric SVOCs due to the efficient capture of both the vapor and particle phases (Nizzetto et al, 2006;Su et al, 2007;Choi et al, 2008;Li et al, 2009;Moeckel et al, 2009b). However, this "filter effect" has been well characterized only in forest ecosystems (Terzaghi et al, 2013).…”
