Abstract
La contaminación medioambiental es un tema de preocupación pública creciente. Como consecuencia de su amplio uso y de sus demostradas consecuencias para el medio ambiente y la salud humana, durante la parte final del siglo XX más de 100 compuestos químicos han sido clasificados como contaminantes y a pesar de que muchos de ellos están siendo restringidos en su fabricación y uso, siguen encontrándose en el medio ambiente. Todo contaminante previamente desconocido o no reconocido como tal, cuya presencia en el medio ambiente no tiene por qué ser necesariamente nueva, se conoce como contaminante emergente. Actualmente, estos compuestos químicos debido a la falta de regulación, la escasez de datos ambientales y sus repercusiones tóxicas y la falta de métodos analíticos para cuantificarlos suponen una creciente preocupación social y científica. La principal característica de los contaminantes emergentes es que son compuestos de elevada producción o consumo que se vierten de manera continua al medio ambiente por lo que no necesitan ser persistentes para ocasionar efectos negativos...
The environment is an issue of growing concern. During the 20th century, more than 105 chemical compounds have been regulated as pollutants in our environment and, even though, many of them are being restricted and other new chemicals products are being introduced. Any contaminant previously unknown or not recognized as such, whose presence in the environment is not necessarily new, is known as an emerging pollutant. Currently, these chemical compounds due to the lack of regulation, the scarcity of environmental data and their toxic repercussions and the lack of analytical methods to quantify them are assuming a growing social and scientific concern. The main characteristic of the emerging pollutants is that they are compounds of high production or consumption that are continuously discharged into the environment, so they do not need to be persistent to cause negative effects...
