“…OCDD, OCDF, 1,2,3,4,6,7,8-HpCDD and 1,2,3,4,6,7,8-HpCDF were the four predominant congeners. This is the same case in the ambient air before rice straw open burning in the study of Kao et al [4]. Nevertheless, the most dominant congeners were different.…”

“…Lin et al [13] reported that emissions from open burning of rice straw were 4200 and 158,800 tonnes/year for the KC area and Taiwan, respectively. Furthermore, Kao et al [4] measured the concentrations of PCDD/Fs in ambient air which were impacted by the open burning of rice straw residue. They reported that the mean PCDD/F concentration (0.409 pg I-TEQ/Nm 3 ) in ambient air at a rice straw field was 4.6 times higher than that (0.089 pg I-TEQ/Nm 3 ) before open burning.…”

“…Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) have been found in the stack gas and fly ash of municipal solid waste incinerators [1], and have been extensively studied owing to their toxicity and associated adverse health effects [2][3][4]. In the USA, municipal waste incineration was the largest PCDD/F emission source (40.5%, 1393.5 rel.…”

“…The open burning of biomass during agricultural debris and forest fires, wildfires, and land-clearing operations has been found to release significant amounts of polycyclic aromatic hydrocarbons and PCDD/Fs. 9 The PCDD/F concentration in the ambient atmosphere is also possibly influenced by these agricultural activities. Furthermore, some heavily emission sources are also located in southern Taiwan.…”

This study investigates the characteristics of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in the ambient air of two municipal solid waste incinerators (MSWIs: GS and RW) and a coal-fired power plant (PW) in the Kaohsiung County (KC) area in Taiwan. The results show that the toxic equivalency (TEQ) concentration in the flue gas of GS and RW averaged 0.090 and 0.044 ng international toxic equivalents (I-TEQ)/N⅐m 3 , respectively. The TEQ concentration in the flue gas of PW averaged 0.050 ng I-TEQ/N⅐m 3 . All PCDD/Fs concentrations from the stack flue gas are lower than the Taiwan Environmental Protection Administration emission standard. Furthermore, the mean I-TEQ concentration in the ambient atmosphere ranged from approximately 0.019 to 0.165 pg I-TEQ/N⅐m 3 , much lower than the environmental quality standards for dioxins in Japan (0.6 pg TEQ/ N⅐m 3 ). This work classified all sampling sites into three clusters according to k-means cluster analysis. The result shows a probable direct correlation between the GS incinerator and site C. Although the concentration from the PW plant did not exceed the emission standard, it was much higher than that in Fernández-Martínez's study. For proper environmental management of dioxins, establishing a complete emission inventory of PCDD/Fs is necessary. The government of Taiwan should particularly pay more attention to power plants to address the information shortage.

“…It was reported that the burned residue from wood sawdust and other biomass could induce DNA strand breaks through in vivo or in vitro exposure (Pandey et al 2005;Bornholdt et al 2007), but the mechanism was not clear. Biomass combustion may produce a complex mixture of compounds, such as aldehydes, PAHs, volatile organic compounds, chlorinated dioxins, respirable particulate matter, and reactive oxygen species (Smith et al 1994;Nolte et al 2001;Long et al 2004;Kao et al 2007). Some of these compounds were known or suspected as genotoxic in exposure to animals and human (Tokiwa et al 1985;Yin et al 1998).…”

Sorption and genotoxicity of sediment-associated pentachlorophenol and pyrene influenced by crop residue ash

Purpose The bioavailability and potential toxicity of sedimentassociated organic compounds are affected by sorption processes. The particulate matter (ash) from field burning of crop residues is one of the primary sources for environmental black carbon, which is regarded as supersorbent for organic contaminants and may reduce their ecotoxicity. This study aimed to investigate the influence of ash on sedimentassociated organic pollutants' potential toxicity. Materials and methods Pentachlorophenol (PCP) and pyrene (PYE) were chosen as the target organic pollutants, earthworms (Eisenia fetida) were used to evaluate the genotoxicity of contaminated sediments in the exposure experiments, and the genotoxicity (expressed as DNA damage) was quantified by comet assay. Sediments amended with different levels of ash (1%, 3%, 5%, and 10%) were selected as the sorbent to investigate the influence of ash on the sorption and genotoxicity of sediment-associated organic compounds. In order to study the toxic effect of ash, the ash-amended sediments without pollutants addition were adopted as exposure systems in the comet assay. Results and discussion The sorption capacity for PCP and PYE increased with ash content in the sediment. The high adsorptivity of ash was attributed to the black carbon contained in the ash, which is in line with many previous studies. When spiked at a concentration of 200 μg/kg, both PCP and PYE exerted significant genotoxic effect on earthworms. The genotoxicity of sediment-associated pollutants decreased as the ash content in sediment increased. The DNA damage in the 5% ash-amended exposure showed no significant difference with that in the control exposure, probably due to the strong sorption capactiy of ash, which decreased bioavailability as well as toxicity of sediment-associated pollutants. However, the 10% ash treatment had a higher DNA lesion than that in the 5% charadded exposure. This may have been caused by the genotoxic compounds and high alkalinity contained in the ash. Conclusions Addition of ash increased sorption and inhibited the genotoxicity of sediment-associated organic toxicants. When added at a high rate (e.g., 10%), ash could also exert genotoxic effect. As field burning is a common land-cleaning method in many agricultural areas, the ecological influence of ash should be given much attention in the future study. More research should be conducted to better understand the mechanism of toxic effect of ash.
