Abstract

The exploration of hydrocarbons causes the dumping of harmful substances in marine and terrestrial areas, so it is essential to know the characteristics and the effects they cause to the native organisms in the areas of influence. Drilling fluid treatments modify the properties of your waste so that it complies with current regulations and is safely disposed of. It’s proposed to determine indicators of contamination to water-based drilling fluids, the level of toxicity and biodegradability, for their final disposal to the environment. Physicochemical parameters and acute toxicity were checked, using bioindicators. A content of fats, oils and total hydrocarbons less than 1% was obtained, regulated for the disposal of contaminated waste in soils. None were toxic to terrestrial or marine biota and were biodegradable.
