Not so far in the distant past a study on water pollution found that common，everyday makeup products being washed down the drain was ending up in well and drinking water．Now a study has found that people pollute themselves．Many of the pollutants are linked to cancer and other serious health（41）B．What's the key cause of this pollution？Common household items，（42）I，appear to be used more by women than men．These include makeup，hair spray and commercial，chemically-made perfumes．These are perfumes that are（43）Fadvertised as having some sort of beneficial effect on the body and are even suggested as a replacement for natural essential oils．Studies on the effectiveness of fragrance oils and health benefits have been（44）E，something neglected to be mentioned．If the chemical scent has cancer-causing properties，it may not make sense to try and use it for helping you sleep or（45）Ayour blood pressure．Manufacturers argue that the risk is non-existent as the levels of chemicals found in the tests were so small．However，with over 60chemicals being found，many of which were non-existent before the turn of the century，researchers make note that these chemicals may be enough to cause problems．
Since the products mentioned are often used by women，it leaves one to wonder if conditions，（46）Dunheard of before the turn of the century，are linked to man-made chemicals？Perfumes in particular，when chemical，have been linked to asthma（哮喘） and other sensitive（47）G．Some groups are asking the government to order manufacturers to place（48）Clabels on each bottle．
Essential oils and real fragrance oils provide a wonderful （49）Hto commercial fragrances．They also have other properties and effects on the body which have been scientifically proven．In addition，you can actually formulate your own scent quite easily!There are many books on perfume（50）Kand the use of essential oils，some quite in-depth and others rather fun．Nowadays there are also many companies making perfumes from pure essential oils．

We're waiting to take trips to outer space．When will it happen？According to individuals in the growing field of space tourism，it may be in five or fifty years．
Space Adventures is taking reservations for the flights，（41）H to the first manned spaceflights．The trip will cost﹩90，000，with a﹩6，000 （42）G required．More than 200people have made reservations，said Sarah，Dalton，the company spokeswoman．
John Spencer of the Space Tourism Society says that a more realistic（43）K for regular space travel is 50years．Issues of expense，difficulty，and danger must still be resolved．Oh yes-a reusable vehicle must also be invented．He adds，however，that ten years from now，a（44）D number of people may be able to visit a space station．He says he expects a fleet of private space vehicles or"space yachts"（游艇） to be in （45）B in 20to 25years．They will do what he calls"orbital super yachting．"After that，there will be cruise lines，like those that travel the Earth's oceans，as well as space hotels and resorts．
There have been only a few studies to determine the public's interest in space tourism，but they all conclude that a （46）Eof people would like to visit space and would be willing to pay good money for it．
According to expert Patrick Collins，between 5million and 20million people will head for space by 2030．He also （47）A 100flights a day leaving Earth．It would be （48）Jto have more than 100hotels in Earth's orbit（轨道），a few more orbiting the moon，and a few on the moon's surface．These hotels would （49）C more than 100，000people，who would work month-long shifts．Each hotel would have a service station．Such service stations would provide oxygen，water，and hydrogen．They might also ship（50）F safe electric power back to Earth．
If all the issues can be resolved，Collins says that space tourism could one day become a﹩1trillion．
