Abstract: A B S T R A C TThis study aimed to evaluate the effects of the application of two types of oil drilling wastes on the development and absorption of barium (Ba) and sodium (Na) by sunflower plants. The waste materials were generated during the drilling of the 7-MGP-98D-BA oil well, located in the state of Bahia, Brazil. The treatments consisted of: Control -without Ba application, comprising only its natural levels in the soil; Corrected control -with fertilization and without wastes; and the Ba doses of 300, 3… Show more

“…No se puede afirmar lo mismo del Na, ya que éste no es considerado esencial para el desarrollo de las plantas, según reportes de la literatura, aunque sí se considera dentro de la dieta del ganado. Se ha señalado que los fluidos que contienen altas concentraciones de sales causan efectos significativos en el suelo y la vegetación (Sampaio et al 2015). Los niveles de Na que se incorporan podrían constituir un problema ambiental delicado si los mismos se acumulan en suelos con mal drenaje, lo que podría inducir una salinización sódica.…”

“…In drilling oil wells in the eastern plains of Venezuela, the main chemical additives used in drilling operations are: barite (barium sulfate), bentonite clay, lime (calcium hydroxide), diesel, caustic soda (sodium hydroxide), chloride of calcium and different polymers [14,15,19], so the abundance of calcium and sodium followed by potassium and magnesium found in the water from the untreated flocculation pits of the Ful-5 and Ful-7 wells (Table 1), while the levels of heavy metals (zinc, copper, chromium, cadmium, iron and manganese) are very low, in some cases at trace levels. In turn, the aluminum content in solution in the case of the Ful-7 well was high (4.4 mg L -1 ), in accordance with the higher acidity (4.91) of its waters.…”

“…The addition of calcium to the environment does not constitute a problem, on the contrary, due to the low pH of these soils, this nutrient acts as a liming substance, improving the natural fertility of the soil and decreasing the levels of soluble aluminum which is potentially toxic. Petroleum fluids containing high concentrations of salts have been reported to cause significant effects on soil and vegetation [19,28]. The levels of sodium that are incorporated could constitute a delicate environmental problem if salts are accumulated in soils with poor drainage, and could induce sodium salinization [29].…”
