“…On Brazil, the legislation only sets limits for BaP in the following categories: drinking water, smoke aroma and olive pomace oil (Brasil, 2003(Brasil, , 2004(Brasil, , 2007. Haapea & Tuhkanen (2006) studied the effect of ozone on HPAs present in the soil, and the removal of these compounds using ozone gas occurred 90% of the time, which corroborates our results (Table 6). Alencar (2009), studying ozonized peanut kernels, described a possible reason for the inefficiency Dzone gas may be present in the moisture content of the grains, since a lower moisture content in the produced gas decreased efficiency.…”

Among energy sources from food, corn is a cereal with significant nutritional characteristics. However, during preprocessing, corn is subject to contamination by polycyclic aromatic hydrocarbons, which are considered carcinogenic, and gas ozone can be used as an alternative for decontamination. This study aims to evaluate the effect of ozonation on the quality of corn grains at different exposure times. Evaluations were performed to assess moisture content, electrical conductivity, germination, germination speed index, colour (brightness parameter, direction red to green, direction yellow to blue, hue angle indicates the colour tone and chroma), and chemical composition, and chromatographic analysis was performed to quantify the polycyclic aromatic hydrocarbons. The ozonation times influence on the quality of the maize grains was lipids, ash and germination percentage and did not promote the degradation of all the polycyclic aromatic hydrocarbons detected in the product.Keywords: contamination; corn; drying.Practical Application: Analyze the degradation of polycyclic aromatic hydrocarbons in maize after ozonation.

“…In a separate study, Pan et al (2009) had observed that B. napus degraded PAHs in humic acid environment. Successes in combined degradation of PAHs have been documented using pressure assisted ozonation (Hong, Nakra, Jimmy, & Hayes, 2008) and integrated treatment using soil washing, ozonation, and biological treatment of substrate (Haapea & Tuhkanen, 2006). Oxidation using ozone in the presence of sand was examined by Choi et al (2001), while combined treatment using sequence extraction with surfactant-electrochemical degradation was successfully employed by Alcántara, Gómez, Pazos, and Sanromán (2008).…”

The demand for processed petroleum products and agricultural produce has exposed our environment to polycyclic aromatic hydrocarbons (PAHs) contamination. PAHs stick to solid sediments and are ubiquitous including soil, water and air. Their presence in these media creates problems because consuming products obtained from these sources could be deleterious to human health since several of these compounds (benz(a)anthracene, benzo(a)pyrene, chrysene etc) have been implicated in causing tumors in animals and cancer in humans. The present review describes several remediation techniques which are efficient and cost effective in removing PAHs from the environment. Some of these conventional clean-up methods are not only environmental friendly; they also present a novel approach in reducing the ability of PAHs to cause prospective risk to humans and the ecosystem.

“…물에 대한 용해도가 낮은 Fluorene은 토양 내로 오염이 되면 계속 잔류하는 특성을 가져 오염 토양이 다수 보고된 바 있으며, 그 범위는 ~180 mg/kg 수준의 상대적으로 높은 농도로 환경 내 침투해있다 (Achten and Hofmann, 2009;Mostert et al, 2010). 따라서, 이렇게 고농도로 토양을 오염시키는 Fluorene은 장기적으로 주변 토양 및 지하수 로의 2차 오염을 야기시킬 뿐만 아니라 주변 생태계를 교 란시킬 수 있는 가능성을 가지고 있기 때문에 이 물질을 분해하기 위해 물리학적, 화학적, 또는 생물학적인 방법들 을 포함한 다양한 노력들을 진행해왔다 (Alcntara et al, 2009;Haapea and Tuhkanen, 2006;Nam et al, 2001;Navarro et al, 2008). 많은 연구 결과들 중 보다 친환경 *Corresponding author : nih@kigam.re.kr 원고접수일 : 2011.…”

The fluorene-degrading strain Sphingobacterium sp. KM-02 was isolated from PAHs-contaminated soil near a mineimpacted area by selective enrichment techniques. Fluorene added to the Sphingobacterium sp. KM-02 culture as sole carbon source was 78.4% removed within 120 h. A fluorene degradation pathway is tentatively proposed based on identification of the metabolic intermediates 9-fluorenone, 4-hydroxy-9-fluorenone, and 8-hydroxy-3,4-benzocoumarin.Further the ability of Sphingobacterium sp. KM-02 to bioremediate 100 mg/kg fluorene in soil matrix was examined by composting under laboratory conditions. Treatment of microcosm soil with the strain KM-02 for 20 days resulted in a 65.6% reduction in total amounts. These results demonstrate that Sphingobacterium sp. KM-02 could potentially be used in the bioremediation of fluorene from contaminated soil.
