“…Then, it is clear that the impacts on the Todos os Santos Bay tend to occur more intensively around the described region. It is important to highlight that the construction of a new shipyard on the Paraguaçu's estuary will increase the traffic and furthermore the risk of contamination by metals and oil spills (Moreira et al, 2013).…”

Surface sediments collected in the intertidal zone of Paraguaçu estuary in July, 2013, were analyzed for organic matter, nitrogen, phosphorus, grain size fractions and partial concentrations of 16 metals. The USEPA 3051A method and ICP-OES and CV-AAS techniques were chosen to metal analysis. Pollution indices (EF, Igeo and PIN) and a comparison with sediment quality guidelines (UET, ERL, ERM, TEL and PEL of NOAA) were conducted in order to evaluate the potential metal impacts over the area. Principal Component Analysis (PCA) and Pearson correlation results showed the importance of organic matter content and the fine-grained fraction of sediments on the control of the bioavailable metals distribution. The Paraguaçu estuary already has anthropogenic enrichment relative to the background level, especially for Mn, whose values exceeded almost 30 times the background at one site (Mn: 1197.30 mg kg(-1)). However, metal levels are still below the reference values with the exception of Hg at one site (Hg: 0.25 mg kg(-1), exceeded TEL and ERL).

“…A ozonização pode ser aplicada a diversos resíduos, principalmente industriais. Nas indústrias petroquímicas e de oleaginosas, a borra oleosa -resíduo sólido perigoso, classe I, que não pode ser descartado sem tratamento prévio (ABNT, 2004;JIN et al, 2014;OMM-E-HANY, 2015;EGAZAR'YANTS et al, 2015) -, uma emulsão orgânica e inorgânica de alto poder calorífico, com compostos tóxicos, metais (MOREIRA, 2013), óleos e micro-organismos (ANNUAL GENERAL MEETING OF BIOMINET, 1991;SHIE et al, 2000;ZHU et al, 2014) é o resíduo mais abundante e tem desafiado diversos tipos de tratamento, apresentando componentes recalcitrantes a tratamentos convencionais (HU; LI; ZENG, 2013; MINAI-TEHRANI; ROHANIFAR; AZAMI, 2015). Diferentes tipos de tratamentos foram sugeridos: Shahi et al (2016) Quadros et al (2016), a borra como estimulante para plantações, porém com ressalvas de contaminação.…”

O resíduo mais amplo do refino do petróleo é a borra oleosa, que pode ser lavada para se tornar um combustível, enquanto a água ácida é conduzida para tratamento convencional. Porém, muitos componentes tóxicos estão nesse resíduo, destacando a necessidade de tratamentos mais rigorosos. Assim, este estudo utilizou e otimizou a ozonização (maximizando a redução de demanda química de oxigênio e minimizando o custo) para o tratamento. Nesse processo, a água usada para lavar a borra foi submetida ao contato prolongado com ozônio em um reator. Por meio da aplicação de design of experiments e metodologia de superfície de resposta, modelos foram gerados para a redução da demanda química de oxigênio e do custo. Normal boundary intersection otimizou os modelos. Minitab gerou e desenvolveu os modelos. O estado ideal para a redução da demanda química de oxigênio foi de 51,1% e R$ 151,5.kW-1 .h-1 para o custo nas condições operacionais de pH, % de potência e tempo iguais a 7; 61,5%; e 45 minutos, respectivamente. Palavras-chave: tratamento de efluentes; oxidação avançada; design of experiments.

“…Reports have shown that 1 ton of petroleum sludge is produced out of 500 tons of crude oil [1]. Oily sludge is a recalcitrant residue characterized as a stable water-in-oil (W/O) emulsions of water, solids, petroleum hydrocarbons, and heavy metals [2,3,4], thus being categorized as hazardous waste [5]. Industrial and hazardous waste management is one of the most significant problems because of the high risk of leaching into the environment.…”

“…These chemical contaminants are found naturally, however, due to anthropogenic activities they become more intense and get released into the environment. A contaminated site thought to encompass a blend of metals and organics are generally considered to be difficult to remediate due to the mixed nature of the contaminants [4,13,14]. Such a gamut of heavy metals and PHCs emanating from refining activities coupled with scrupulous agricultural practices distort organic matter decomposition via the natural bacterial flora [14,15,16].…”

“…Such a gamut of heavy metals and PHCs emanating from refining activities coupled with scrupulous agricultural practices distort organic matter decomposition via the natural bacterial flora [14,15,16]. Although heavy metals at extreme concentrations are toxic to microorganisms, plants, animals and humans, a substantial proportion of minerals (metals at acceptable concentrations) are beneficial [4,17]. Defects in petroleum sludge management in form of releasing the waste into the environment is the current most attended concern [18].…”

The concentrations of some heavy metals (Chromium, Cadmium, Lead, Nickel, Copper, Cobalt, Manganese, Iron and Zinc) in petroleum sludge impacted soils were determined to evaluate their contamination levels using atomic absorption spectrophotometer. The petroleum sludge samples were collected from the discharge pit of Warri Refinery and Petrochemical Company (WRPC) while the soil samples were collected from five selected oil-impacted communities (Ubeji -500 m, Ekpan -1.5 km, Aja-Etan -2.5 km, Ifie-Kporo -3.0 km, Ijala-Ikenren -3.8 km from Warri refinery and were coded A, B, C, D and E respectively). A control sample was also collected 8.5 km away from the refinery. The results obtained revealed that with the exception of Fe, the sludge samples contained the highest concentrations (in mg/kg dry weight) of Chromium (2462.6±0.5), Lead (406.7±0.2), Copper (201.3±0.0), Manganese (8335.1±0.9) and Zinc (1009.2±0.3) while Iron was highest (10313.5±2.3) in site A. All the metals were higher in the studied sites than the control sites and a stepwise decrease in metal contents were observed from A to E. Some geochemical
