Los resultados de la investigaci\u00f3n muestran que las playas de Tel Aviv y Hadera fueron las m\u00e1s contaminadas de las playas examinadas.<\/em><\/strong><\/p>\n

(Comunicado de la portavoz de la Universidad de Tel Aviv)<\/p>\n

Un nuevo estudio de la Universidad de Tel Aviv realizado en cooperaci\u00f3n con el Centro de Investigaci\u00f3n del Mar Mediterr\u00e1neo de Israel, examin\u00f3 el nivel de poluci\u00f3n por micropl\u00e1sticos a lo largo de la costa israel\u00ed. Los investigadores recogieron muestras de arena de seis playas, desde Haifa hasta Ashkelon. Los resultados de la investigaci\u00f3n revelaron que la costa israel\u00ed est\u00e1 contaminada con m\u00e1s de dos millones de toneladas de micropl\u00e1sticos, siendo las playas m\u00e1s contaminadas, las de Tel Aviv y Hadera.<\/p>\n

A la luz de estos preocupantes resultados, los investigadores advierten que la exposici\u00f3n a los residuos micropl\u00e1sticos es inevitable. Debe destacarse que, generalmente se ha demostrado que los micropl\u00e1sticos son peligrosos tanto para el medio ambiente como para la salud humana.<\/p>\n

El estudio fue dirigido por el estudiante de doctorado Andrey Ethan Rubin y la estudiante para el Master, Limor Omeysi del Laboratorio de la Dra. Ines Zucker de la Facultad de Ingenier\u00eda Fleischman y la Escuela Porter de Medio Ambiente y Ciencias de la Tierra. El estudio fue publicado en la revista cient\u00edfica Marine Pollution Bulletin.<\/p>\n

Rubin explica que en el transcurso de 1921, los investigadores recogieron muestras en seis \u00e1reas, a lo largo de la costa: Ashkelon, Rishon LeZion, Tel Aviv, Hadera, la Playa Dor y Haifa. Luego, las muestras fueron llevadas al laboratorio donde fueron realizados varios an\u00e1lisis, entre ellos, el recuento de part\u00edculas, las mediciones de masa, el an\u00e1lisis de im\u00e1genes, y el an\u00e1lisis qu\u00edmico para identificar el pol\u00edmero del cual ha sido fabricado el pl\u00e1stico, as\u00ed como los elementos adsorbidos en las part\u00edculas de micropl\u00e1stico. Los investigadores descubrieron, entre otras cosas, que las muestras inclu\u00edan pl\u00e1stico procedente de envases de alimentos, productos de pl\u00e1stico de un solo uso y redes de pesca.<\/p>\n

\u201cFue interesante ver que los pl\u00e1sticos de origen terrestre, como los envases de alimentos eran m\u00e1s dominantes que los pl\u00e1sticos de origen marino, como las redes de pesca\u201d, afirma Rubin. \u201cEsto indica la necesidad para una mejor regulaci\u00f3n de los residuos costeros\u201d.<\/p>\n

Los resultados de la investigaci\u00f3n muestran que las playas de Tel Aviv y Hadera fueron las m\u00e1s contaminadas de las playas examinadas. El nivel de contaminaci\u00f3n en estas playas, que est\u00e1n ubicadas cerca de los estuarios de los arroyos (el Yark\u00f3n en Tel Aviv y el arroyo Alexander en Hadera) era cuatro veces m\u00e1s alto que el de Rishon LeZion y la Playa Dor, que fueron las dos playas con la m\u00e1s baja concentraci\u00f3n de part\u00edculas de micropl\u00e1stico. Aun as\u00ed, incluso en la reserva natural de la Playa Dor, que es limpiada frecuentemente, fueron halladas una considerable cantidad de part\u00edculas micropl\u00e1sticas.<\/p>\n

La evaluaci\u00f3n de los investigadores es que el alto nivel de contaminaci\u00f3n de las playas de Tel Aviv y Hadera y el hecho de que est\u00e9n muy cerca de los arroyos indica que las aguas de los arroyos arrastran part\u00edculas de micro pl\u00e1stico al mar, lo que intensifica el nivel de contaminaci\u00f3n en la playa.<\/p>\n

Por ejemplo, los investigadores se\u00f1alan que el arroyo Alexander recoge los lixiviados de las aguas residuales no tratadas, de la Margen Occidental, as\u00ed como los residuos de las zonas agr\u00edcolas e industriales situadas cerca del cauce del rio. Del mismo modo, en el rio Yark\u00f3n se acumulan micropl\u00e1sticos procedentes de los centros industriales de Tel Aviv.<\/p>\n

\u201cNuestra investigaci\u00f3n revela que la costa israel\u00ed contiene probablemente m\u00e1s de dos toneladas de residuos micropl\u00e1sticos\u201d, afirma Rubin. \u201cLas condiciones ambientales descomponen lentamente este pl\u00e1stico en part\u00edculas a\u00fan m\u00e1s peque\u00f1as. Cuanto m\u00e1s peque\u00f1as son las part\u00edculas de pl\u00e1stico, m\u00e1s dif\u00edcil es eliminarlas del medio ambiente, y m\u00e1s peligrosas son para el medio ambiente y para nuestra salud. Las part\u00edculas micropl\u00e1sticas que van a la deriva en el mar son tragadas por los peces, y sus restos terminan llegando a los humanos\u201d.<\/p>\n

La Dra. Zucker agrega: \u201cNuestros estudios sobre micropl\u00e1sticos revelan el estado actual de la contaminaci\u00f3n por micropl\u00e1sticos a lo largo de la costa mediterr\u00e1nea de Israel, y proporciona conocimiento sobre los efectos de la presencia de micropl\u00e1sticos en el medio ambiente. La investigaci\u00f3n sobre el monitoreo de los pl\u00e1sticos en Israel a\u00fan es deficiente, y debemos monitorear las part\u00edculas de pl\u00e1stico m\u00e1s peque\u00f1as y de las muestras ambientales adicionales, como el agua de mar y los arroyos, con el fin de comprender mejor los patrones ambientales con respecto a la presencia de los micropl\u00e1sticos. De una forma u otra, parece que la exposici\u00f3n a los residuos micropl\u00e1sticos es inevitable. Estamos trabajando en la evaluaci\u00f3n de los impactos ambientales y sanitarios que pueden aparecer, debido a la prevalencia y a las altas concentraciones que encontramos. Desde una perspectiva pr\u00e1ctica, es necesario adoptar medidas regulatorias para reducir la contribuci\u00f3n de Israel a la contaminaci\u00f3n por micropl\u00e1sticos en el Mediterr\u00e1neo\u201d.<\/p>\n
