“…Alterations in the growth and production of biomass of plants in contaminated soil have been reported by several researchers (Udo and Fayemi, 1975;Malallah et al, 1996;Li et al, 1997;Chupakhina and Maslennikov, 2004;Alkio et al, 2005;Mayer et al, 2005;Merkl et al, 2005;Agbogidi et al, 2006;Peña-Castro et al, 2006;Rezende, 2006;Santos, 2006).

“…However, if the roots grow in a petroleum-polluted environment, the soil particles are covered in a hydrophobic layer that reduces water availability. This causes anoxic stress and hydric stress and then the hydrophobic nature of the pollutant also causes chemical stress (Peña-Castro et al, 2006). Therefore, the presence of organic hydrocarbons in the soil in large quantities can block the absorption of water and nutrients by the plants (Baker, 1970;Udo and Fayemi, 1975;Reis, 1996).…”

“…The seedling in the petroleum-contaminated soil exhibited a delay in the emergence of eophylls when compared to the bioremediated soil and the uncontaminated soil (Figure 7j-l). Peña-Castro et al (2006), studied the noxiousness of petroleum on Cynodon dactylon L. Pers. plants observing chlorosis and a reduction in the number of leaves and root growth in all of the oil concentrations tested.…”

Germination and initial growth of Campomanesia xanthocarpa O. Berg. (Myrtaceae), in petroleum-contaminated soil and bioremediated soil

et al. 2010

In 2000 there was an oil spill at the Getúlio Vargas Refinery (REPAR) in Paraná. Nearly five years after contamination and the use of bioremediation, a study was carried out to identify the effects of the contaminated soil and the bioremediated soil on the germination and initial growth of C. xanthocarpa. The experiment was established with soil from REPAR, with three treatment groups: contaminated soil (C), bioremediated soil (B) and uncontaminated soil (U); with five repetitions of 50 seeds each. There was no significant difference in the percentage of germination and the speed of germination index. The production of total biomass (30 -60 days) and shoot biomass (60 days) was greater in the bioremediated soil compared to the other treatments. The averages for the root biomass were lower in the contaminated soil than in the bioremediated soil. The shoot length and the total length of the seedling in the contaminated soil and uncontaminated soil were lower than in the bioremediated soil.Keywords: biomass, gabiroba, hydrocarbon contamination, seedling growth. Germinação e crescimento inicial de Campomanesia xanthocarpa O. Berg. (Myrtaceae), em solo contaminado com petróleo e solo biorremediado ResumoEm 2000, ocorreu um vazamento de petróleo na área da Refinaria Getúlio Vargas (REPAR), no Paraná. Após cerca de cinco anos da contaminação e utilização do processo de biorremediação, pretendeu-se identificar os efeitos do solo contaminado e do solo biorremediado na germinação e no crescimento inicial de C. xanthocarpa. O experimento foi montado com solo da REPAR, com três tratamentos -solo contaminado (C), solo biorremediado (B), solo não contaminado (U) -e cinco repetições com 50 sementes cada. Não houve diferença significativa na porcentagem e no índice de velocidade de germinação. A produção de biomassa total (30 -60 dias) e biomassa da parte aérea (60 dias) foram maiores no tratamento biorremediado em relação aos demais tratamentos. As médias para a biomassa da raiz foram menores no solo contaminado do que no solo biorremediado. O comprimento da parte aérea e o comprimento total da plântula no solo contaminado e no não contaminado foram menores do que no biorremediado.Palavras-chave: biomassa, gabiroba, contaminação por hidrocarbonetos, crescimento de plântula.

The current study evaluates the performance of a pilot scale fed batch reactor (FBR), fo llowed by coagulation and sand filtration, for the treatment of an oil refinery wastewater. The total reductions in COD, BOD, oil contents and phenol were 95.11%, 94.30%, 99.47% and 100%, respectively, with FBR followed by coagulation and sand filtration. This FBR-coagulation-sand filtration treatment system also removed the toxicity from the oil refinery wastewater. Treated wastewater by this approach meets National Environ mental Quality Standards (NEQS) of Pakistan, and can be safely released into the environment.

“…O contaminante pode ser absorvido pelas plantas (Bossert & Bartha 1985;Alkio et al 2005;Tan et al 2005), além de alterar as propriedades do solo (Racine 1994;Li et al 1997;Martinez & López 2001;Roy et al 2003;Chupakhina & Maslennikov 2004;Peña-Castro et al 2006). Solos com hidrocarbonetos têm tendência a reter menor quantidade de água (Roy et al 2003;Peña-Castro et al 2006), a apresentar menor disponibilidade de oxigênio (Pezeshki et al 2000;Merkl et al 2005) e de nutrientes (De Jong 1980).…”

Efeito do solo contaminado com óleo diesel na estrutura da raiz e da folha de plântulas de Sebastiania commersoniana (Euphorbiaceae) e Schinus terebinthifolius (Anacardiaceae) ABSTRACTEff ect of diesel contaminated soil on root and leaf of Sebastiania commersoniana (Euphorbiaceae) and Schinus terebinthifolius (Anacardiaceae)). Th e objective of this study was to evaluate whether the diesel contaminated soil alters the structure of the root and eophyll of S. commersoniana (Euphorbiaceae) and S. terebinthifolius (Anacardiaceae) seedlings. For each species three treatments with contaminated soil were tested, and compared to a control of uncontaminated soil. Th e treatments diff ered by the time between contaminations and sowing. S. commersoniana was sown 60, 120 and 210 days and S. terebinthifolius 30, 90 and 180 days aft er contamination. Samples of root and eophyll were collected 30 days aft er sowing and analyzed qualitatively and quantitatively. Seedlings of S. commersoniana and S. terebinthifolius, grown in diesel contaminated soil, had their root and eophyll anatomy modifi ed. Th e time interval between contamination and sowing interferes with the soil phytotoxicityl. When greater the time interval between contamination and sowing lower were the anatomical changes. Seedlings of S. terebinthifolius seemed more resistant to contamination than those of S. commersoniana.
