Exploring for oil and extracting it from the Amazon region of northeastern Ecuador has boosted the countrys income over the last several decades, but it has also resulted in a "public health emergency" due to the negative effects on the local environment and on the health of persons who live in the petroleum-production areas. That is according to an English-language article published in the most recent (March 2004) issue of the "Revista Panamericana de Salud Pública/Pan American Journal of Public Health." The "Revista/Journal" is a monthly, peer-reviewed scientific journal. The "Revista/Journal" article summarizes and reviews the scientific research that has been done on the environmental and health consequences of oil development in Ecuador.
Since the 1970s more than two billion barrels of crude oil have been pumped from oil fields in the Ecuadorian Amazon. Petroleum has been the "engine" for Ecuadors economy, helping push per capita income from US$ 290 in 1972 to US$ 1200 in 2000. Oil now accounts for some 40% of the nations export earnings and of the national governments budget.
While boosting the Ecuadorian economy, oil production has also had serious consequences for the environment. For example, in just the period of 1972 through 1993, more than 30 billion gallons (114 billion liters) of toxic wastes and crude oil were discharged into the land and waterways of the Ecuadorian Amazon. This far exceeds the 10.8 million gallons (40.9 million liters) spilled in the "Exxon Valdez" tanker disaster in 1989 in Alaska, one of the largest sea oil spills that has ever occurred.

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
