“…Outros resíduos dessa atividade industrial são o fluído de perfuração e o cascalho (fragmentos das rochas atravessadas) que podem levar, por sua disposição inadequada, a contaminação de aquíferos e a salinização dos solos representando um importante potencial de impacto ambiental decorrente da atividade de exploração de petróleo (Ball et al, 2012;Freitas et al, 2015).…”

A salinização do solo pode ocorrer de forma antropogênica ou secundária ou como resultado de processos naturais a exemplo da intemperização dos minerais ou até mesmo pelo aumento da capilaridade das águas subterrâneas mais salinas em regiões com lençol freático mais baixo. Entre as fontes antropogênicas de salinização do solo se destacam atividades industriais como a exploração de petróleo, a mineração e destacando-se ainda as práticas agrícolas não sustentáveis. A implantação de sistemas de irrigação no semiárido muitas vezes promovem mudanças que resultam no acúmulo de sais na superfície do solo, ascensão do lençol freático e contaminação dos recursos hídricos impactando a dinâmica ambiental daquele local. Diante disso esta revisão de literatura teve como objetivo abordar os principais impactos relacionados com a salinização secundária e seus efeitos nas propriedades do solo, analisando-se ainda o cultivo em condições salinas de culturas de importância agrícola e seus impactos sobre o desenvolvimento das plantas. Esse trabalho foi direcionado por um levantamento bibliográfico que agrupou temas importantes sobre salinização secundária do solo e o cultivo de culturas resistentes a esse tipo de ambiente. Com base nos resultados obtidos nessa revisão, conclui-se que a irrigação com água de baixa qualidade tem se apresentado como alternativa para a produção agrícola, principalmente para culturas que tem se mostrado resistentes a solos salinizados e que pode representar uma importante alternativa para regiões com escassez de água.

“…Barium concentrations were even higher than the limit for industrial areas, which is 750 mg kg -1 . According to Magalhães et al (2014b) and Freitas et al (2015), Ba concentration in areas contaminated by oil well drilling residues is increased due to waste disposal near the wells. It is worth mentioning that Ba has no direct relationship with the genesis of local rocks or respective mineralization, as seen in local geochemical surveys (LICHT; BITTENCOURT, 2013).…”

“…In general, drilling fluids contain hydrocarbons, sodium, and heavy metals such as barium (Ba) and lead (Pb) (BAKKE; KLUNGSØYR; SANNI, 2013;ANDRADE et al, 2014;FREITAS et al, 2015). Among the main components, barite (BaSO 4 ) adds large amounts of Ba to the waste produced (LIMA et al, 2012;MAGALHÃES et al, 2014a).…”

Indiscriminate disposal of waste from the oil industry has led to contamination of soils and water sources and toxic effects in the biota. Thus, this study aimed to assess barium (Ba) and lead (Pb) spatial variability in disposal sites for oil well drilling and prospecting wastes. The soil in the study area is classified as Red Latosol, and the area is located in Santa Maria do Oeste, Paraná State (Brazil). Barium and Pb spatial variabilities were determined using a 76-point sampling grid. The levels of metals were determined in soil samples collected at each sampling point, at the depth ranges of 0.0-0.3, 0.3-0.6, 0.6-0.9 and 0.9-1.2 m. Data were mapped using geostatistical interpolators for spatial dependence determination, modeling and validation of semivariograms, and respective interpolation. Thirty Ba and Pb high concentration samples were selected for leaching and solubilization assays. As semivariogram analysis showed spatial dependence, mapping by ordinary kriging was performed for both metals. The high levels found for both metals arose from well drilling activities, as no direct relationship was found between such levels with geology and genesis of the local rock. The concentrations of the metals were higher than the research values considering the Agricultural / AP-Max scenario, therefore, the study area was characterized as class 4 (contaminated). Although these metals have low solubility, i.e. low contamination risk to subsurface waters, they may pose contamination risks to water bodies by means of soil runoff.

“…These residues are generated by mixing the fluid, which is an oil-water emulsion with colloidal matter (which may include bentonite, BaSO 4 , and sodium chloride, among other additives), and ground rock (Darley & Gray, 1988). The effects of applying drilling waste on soil have been investigated (Lima et al, 2012;Magalhães et al, 2014b) and have shown that the elements barium, in reducing conditions, and sodium (Freitas et al, 2015) are the most limiting for the growth of several crops, including rice , sunflower (Sampaio et al, 2015), and Brachiaria (Andrade et al, 2014). However, there are few studies that show the effects on soil invertebrates of applying drilling waste.…”

Toxicity of Drilling Waste from Oil Wells on Oligochaeta

et al. 2018

The most abundant and critical elements in residues from well drilling and prospecting are barium and sodium. Ecotoxicological tests have been used to evaluate the toxicity caused by toxic substances present in the soil. The objective of the present study was to verify the effect of the application of drilling residue from oil wells on Oligochaeta activity. After incubation of the soil with residue doses -BaSO 4 and NaCl -three ecotoxicological tests were performed in which the species Eisenia andrei was used as a bioindicator. The avoidance behavior test showed that there was a negative effect of the application of the residue at a dose of 234 t ha -1 on Oligochaeta activity. However, the application of BaSO 4 alone did not show damage to the earthworms, unlike what was observed for NaCl application. These results indicate that sodium was the element that most restricted the activity of these organisms.
