Los productos químicos "surfactantes" encontradas en muestras de líquido de fracking recogido en cinco estados de EEUU no eran más tóxicos que las sustancias que se encuentran comúnmente en los hogares, de acuerdo con un análisis, primero en su tipo, realizado por investigadores de la Universidad de Colorado en Boulder.
The “surfactant” chemicals found in samples of fracking fluid collected in five states were no more toxic than substances commonly found in homes, according to a first-of-its-kind analysis by researchers at the University of Colorado Boulder.
Fracking fluid is largely comprised of water and sand, but oil and gas companies also add a variety of other chemicals, including anti-bacterial agents, corrosion inhibitors and surfactants. Surfactants reduce the surface tension between water and oil, allowing for more oil to be extracted from porous rock underground.
On a tropical island vacation, one of the last things you want to worry about is food poisoning. Yet for many, a trip to the tropics includes a painful education in a mysterious food-borne illness called Ciguatera Fish Poisoning, or CFP.
Every year, thousands of people suffer from CFP, a poisoning syndrome caused by eating toxic reef fish. CFP symptoms are both gastrointestinal and neurological, bringing on bouts of nausea, vomiting, diarrhea, headaches, muscle aches, and in some cases, the reversal of hot and cold sensations. Some neurological symptoms can persist for days to months to years after exposure. There is no quick way to test for the toxins, and unless action is taken within hours of the poisoning, no cure once you’re sick.
En unas vacaciones en una isla tropical, una de las últimas cosas por las que quieres preocuparte es la intoxicación alimentaria. Sin embargo para muchos, un viaje a los trópicos incluye una educación dolorosa con una misteriosa enfermedad transmitida por alimentos llamada Intoxicación Ciguatera de Pescado (ICP)
The deliberate, large-scale intervention in the Earth’s climate system is not a “quick fix” for global warming, according to the findings of the UK’s first publicly funded studies on geoengineering.
The results of three projects – IAGP, led by the University of Leeds; SPICE, led by the University of Bristol; and CGG, led by the University of Oxford – are announced at an event held at The Royal Society, London, on 26 November.
A medida que el planeta continúa calentándose, las olas de calor y otros fenómenos meteorológicos extremos que ocurrían una vez en cientos de años, o casi nunca, se convertirán en el "nuevo clima normal", en la creación de un mundo con mayores riesgos e inestabilidad, según advierte un nuevo estudio del Banco Mundial.
