Chemistry Bootcamp Lectures Intro To Chem - Introduction Chemistry is the science of matter, especially its chemical reactions, but also its composition, structure and properties. Classification and Properties of Matter In chemistry and physics, matter is any substance that has mass and takes up space by having volume.
Well digging saw a marked decrease in water borne infections. By it was discovered that arsenic was present in these wells. The first symptoms found in people drinking arsenic contaminated water include pigmentation changes in the skin and skin thickening or hyperkeratosis.
After about 10 years drinking that water symptoms extend to skin and internal cancers. The World Health Organization report that arsenic in drinking water could end up causing between , to , deaths in Bangladesh from cancer. Arsenic levels appear to be lower in shallower, ground water or in much deeper aquifers and this knowledge should hopefully contribute to reducing the risks in future.
On a lighter note, I'm afraid there isn't much evidence despite its link with the Greek word for potent that arsenic is an aphrodisiac. It's a shame because it might have been rather useful if it was.
An arsenic-based drug called Salvarsan was developed in by Nobel laureate Paul Ehrlich to treat the sexually transmitted disease syphilis.
Chemistry world's Bea perks on the science of element number 33, arsenic. And if you think arsenic is nasty, wait till you meet next week's element. It sounds like a Doctor Who monster and in a number of ways this element does have a few properties that would make it suitable for any good, outer space sci-fi horror movie. For a start, like many space monsters it comes from slime. Every good monster must have a secret weapon and tellurium is no exception.
It gives its enemies garlic breath. Really bad garlic breath. That was Peter Wothers who will be here to tell the tale of the smelly element tellurium on next week's Chemistry in its element.
I hope you can join us. I'm Chris Smith, thank you for listening and goodbye. Chemistry in its element is brought to you by the Royal Society of Chemistry and produced by thenakedscientists.
