1In the first study to look at what happens over the years to the billions of pounds of plastic waste floating in the world's oceans, scientists are reporting that plastics — reputed to be virtually indestructible — decompose with surprising speed and release potentially toxic substances into the water.2Chemicals are an important aspect in our economy and serves with many uses. However, when chemicals are not properly used they can create a problem with global security. There is the threat of chemical spills and also a possible use by terrorists. Many chemicals are stored and processed at numerous facilities. If terrorists were to attack any chemical plants in the United States it would kill more than 2 million people. There is also a long-term threat of contamination that will affect both people and the environment. These chemicals can contaminate the water and cause many illnesses to people. In 1962, Rachel Carson informed the public about the horrible effects that DDT had on the environment and health problems of humans. But it took 10 years for the United States to ban this compound. But not all chemicals pose a security threat. To reduce the use of chemicals facilities are required to provide the public with annual chemical releases. This has allowed our society to force these facilities to use these chemicals better and safer. The Stockholm Convention on Persistent Organic Pollutants came into effect in May 2004. This treaty would ban or restrict the production and use of 12 hazardous chemicals. There will always be an abundance of chemicals but their use needs to be lowered to make them less of a threat. 3A captain of a ship drunkenly crashes a massive oil tanker along a reef and changes the physical and emotional world forever. Chemical spills are major problems that plague the environment. Strict government regulation is trying to aid with this problem, but governmental leaders face many challenges. Disposal of harmful chemicals is often difficult and costly. Since chemical waste has destroyed the environment, steps are being taken to prevent further pollution. 看看，参考一下吧：

我来写吧：Nowadays，people across the globe are paying more and more attention to their health conditions and what we bring about to the natural environment. 然后写化学品对人类的危害：1.食品中的有害添加剂影响人类健康；2.化学品影响水质和空气质量；3.不当化学品影响药物质量。再写化学品对环境的影响。字数差不多够了。（主要是太晚了。要不然就帮你写完了）

有机化学英语论文Abstract In this work the effects of the microporosity and chemical surfaceof polymeric adsorbents on adsorptive properties of phenol wereinvestigated. Textural parameters of four kinds of polymeric resins namely AB-8 D4006 NKA-II and D16 resin were separately measuredby ASAP 2010. The surface chemistry of these polymeric resins was determined by means of inverse gaschromatography (IGC) and diffusereflectance infrared Fourier transform spectroscopy (DRIFTS). Static equilibrium adsorption experiments were carried out to obtain theisotherms of phenol on the polymeric resins. It was shown that NKA-II and AB-8 resin possessed relatively high BET surface areas andmicropore volumes while D4006 and D16 resin possessed comparatively low BET surface areas and micropore volumes. The results of IGCexperiments revealed that NKA-II resin had extraordinary high specific component of the free energy of adsorption both for polar acetone andbenzene probe and thus extraordinary strong surface polarity compared to the other polymeric resins. It was also found that the isotherm ofphenol on NKA-II was much higher than that on the other polymeric resins due to its strongest surface polarity and largest micropore volumeamong four kinds of resins. These experimental observations indicated that adsorption of phenol on the polymeric resins depended greatly ontheir microporosity and surface chemistry. The well-developed microporosity and the strong surface polarity would improve the adsorptionof phenol on the polymeric resins. 2004 Elsevier B.V. All rights reserved.

The Importance of Chemistry in Daily LifeMost people have chosen to write their essay about how chemistry has played an important role in everyday life. I have chosen to ask, how doesn't it play a role in everyday life? The simple fact is that chemistry plays an important role in every person's daily activities from the moment we're born.So what role does chemistry really play in everyday life? Well, this involvement usually begins first thing each morning. Most people wake up to an alarm or radio. These common household items contain batteries, which make them very chemically dependent. These batteries contain positive and negative electrodes. The positive electrode consists of a carbon rod surrounded by a mixture of carbon and manganese dioxide. The negative electrode is made of zinc. Chemistry plays an important role in the discovery and understanding of materials contained in these and many other common household items. Things like household cleaners and water purification systems are vitally dependent on chemistry. Without chemistry something as simple as scrubbing a toilet without fear of severe burns or small explosions might not be possible.Next, though it isn?t widely known, chemistry is also heavily involved with the manufacturing of things such as makeup and soap. Each time you bathe you are witnessing chemistry at work. Chemicals such as cetyl alcohol and propylene glycol are typical ingredients in the soap used to wash your hair and skin. Without chemistry, these materials (or combinations of these materials) might be hazardous or might not exist. The chemical coloring agents used in makeup and nail polish would not be possible without an understanding of the chemicals involved.Almost anything you do during the course of a normal day involves chemistry in some way. The gas and tires in cars we drive, the makeup we put on our faces, the soaps and cleaners used everyday, burning wood or other fossil fuels, chemistry is all around you each and every day. The associations are practically limitless. So, as you go about your daily activities, remember to thank chemistry. As my teacher always says, remember, "CHEMISTRY IS LIFE!"
