Researchers from the University of Valencia, in collaboration with the Centre for Research on Desertification (Cide, composed of university, the Generalitat and the CSIC), have been detected up to 15 drug compounds in water, sediment and soil natural park Pego -Oliva. The results of the study, which warns of the danger to biodiversity, are published in the journal Science of the Total Environment.
Environmental contamination by traces of drugs is a growing problem in recent years, as evidenced by the fact that last year the Environment Committee of the European Parliament approved that diclofenac, a drug present in known anti-inflammatory drugs such as Voltaren and detected in rivers such as the Ebro Júcar and outside classified as dangerous in the annexes of the Water Framework Directive.
In this case, the scientists tracked the Pego-Oliva park the presence of the 17 drugs most consumed, according to the Department of Information and Science News (SINC). For this purpose, water samples were taken 34, 16 and 23 of soil sediment. The analysis showed that all samples were contaminated water at least one drug, and all except one of sediment. The drug distribution in the soil was more irregular. In total there were 15 of the 17 drugs studied.
The most frequent drug compounds in water samples were inflammatory and analgesics such as ibuprofen. In sediments and soils analyzed, carbamazepine and acetaminophen, also known as paracetamol, were the most abundant.
"The European Union is considering including some drugs as priority pollutants," explains researcher Yolanda Valencia University Stang, author of the study. "The risk assessment indicates a risk to fish and, therefore, it would be desirable a more continuous and deep," he concludes.
According to the study, although more tests are needed to assess the impact of these substances in the environment, the results imply a "high risk" to fish the marsh, due to presence of ibuprofen and antibiotics. The potential risk to human health due to the contamination of drinking water should also be studied, and the impact on nearby crops, mainly rice and orange-, scientists added.
"The concentrations detected in the marsh are low, but you can not rule out an indirect effect as the emergence of resistance," says Stang.
The presence of drugs indicates the constant contribution of these substances from the wastewater treatment plant near the park, due to their incomplete removal. According to Pico, would require "a study of the purification systems and elimination of drugs, and promote the development of viable and effective removal of these compounds."
