WHAT IS ARSENIC Arsenic is a chemical element with symbol As and atomic number 33. Arsenic occurs in many minerals‚ usually in conjunction with sulfur and metals‚ and also as a pure elemental crystal. The main use of metallic arsenic is for strengthening alloys of copper and especially lead (for example‚ in car batteries). Arsenic is a common n-type dopant in semiconductor electronic devices‚ and the optoelectronic compound gallium arsenide is the most common semiconductor in use after doped silicon

Tyler Kerschner HN English 11 1 May 2013 It’s a Fracking Problem Fracking is increasing in the U.S.‚ but with this increase of natural gas comes an increase of safety concerns. The process of hydraulic fracking requires chemicals that can affect the families that live nearby. These chemicals also affect the environment on the land and in the air. With fracking there comes its positives and its negatives‚ some good and some bad. There are very few regulations on how fracking can be done‚ but

The Nasca is an ancient civilization of people located in the Nasca region on the southern coast of Peru‚ living between approximately 1 and 750 AD. Many scholars believe the Nasca originated out of the Paracas culture and were most likely a group of small rural villages that were situated near each other. The Nasca appeared to be self-sufficient and based much of their life on agriculture‚ especially the cultivating of corn. The villages had distinctive art‚ especially multicolored pottery and

detect the presence of a connection between the two levels. This relationship occurs as an exchange from superficial waters (streams and rivers) to the shallow aquifers. Where superficial waters are contaminated‚ as in the Tor Sapienza stream‚ pollutants move to the shallow aquifers too‚ due to the decreased pressure of the over-exploited aquifer. Moreover‚ uncontrolled drilling activity‚ diffused in urban areas‚ makes it possible the connection between shallow and deep ground water. Notwithstanding

generations. Through the natural water cycle‚ the earth has recycled and reused water for millions of years. Water recycling generally refers to projects that use technology to speed up these natural processes. Recycled water can reduce much of Oahu’s aquifer water demands‚ as long as it is adequately treated to ensure water quality appropriate for the use. The recycling of water has many benefits. The main benefit is that by recycling water‚ we are saving ground water for other uses. Another benefit
