A recent study concludes that the waters of Antarctica contain caffeine, ibuprofen, paracetamol and cocaine, at levels equivalent to those recorded in Europe or other continents. The presence of the main metabolite of cocaine was detected in one of the 10 analyzed points, near the scientific and military base Marambio of Argentina.


 Yolanda Valcárcel, a researcher at the Rey Juan Carlos University in Madrid and co-author of the study, says in statements to the newspaper El País that for now "drug concentrations are very small" and that "in no case represent an environmental danger."The teamThe results of the research, which was carried out by a group of scientists from the Geological and Mining Institute (IGME), Universidad Autónoma de Madrid and the National Water Institute of Argentina, have been published in the journal Environmental Pollution.For this field work, researchers collected water samples in streams, lagoons, glacial drains and untreated wastewater discharges, in areas considered sensitive by the presence of tourists and scientific bases. Scientists, according to the paper, processed the samples looking for the traces of 25 drugs, 21 recreational substances and illegal drugs.Twelve of them have appeared in the analyzes, being the compounds of greater concentration anti-inflammatories and analgesics, that present a "high risk" for the environment, says the report. Within the group of reactive substances, caffeine is at the top of the list, followed by ephedrine, used for medical purposes.
The Spanish researcher stresses that "human presence is introducing contaminants not analyzed to date that, depending on their toxicity, persistence or bioaccumulation, could cause damage to the Antarctic ecosystem."
