Pollution is a serious global issue that has been occurring for as long as humans have inhabited the planet. There are many different varieties of pollution, as well as an abundance of materials, both natural and synthetic, that the earth has been contaiminated with. Shifrin ( 2005), states: “To date, wastes remain a fact of life and there are only three places to dispose of wastes-air, water, or land. Waste management always involves tradeoffs.” (p. 676). Even though Shifrin is correct in his
Assignment 3 Q1: how does the industry work? Polyethylene is a petrochemical product that has been widely used in the plastic manufacturing, such as packaging, trash bins, and food containers. It is produced mainly from the polymerization process of ethylene, which is an ingredient derived from cracking crude oil and natural gas. There are three types of polyethylene: low-density polyethylene (LDPE); high density polyethylene (HDPE); and low linear density polyethylene (LLDPE), and each of them has distinctive
process of becoming privatized by the Argentine government, Dow Chemicals saw the acquisition of this company as a golden opportunity to become the leading polyethylene player in Latin America. Dow Chemical’s was already a major player in the chemicals (ethylene), plastics (polyethylene), and agricultural products industries holding position as a low-cost producer. Breaking each segment of their business down into these categories respectively, Dow Chemicals was able to generate annual revenues of 20
Manufacturing Cycle and Environmental Impact The most common form of polyethylene is petroleum based or olefins based; as before mentioned polyethylene compounds have a wide commercial applicability and are made from non-renewable resources (Harding, Dennis, von Blottnitz, Harrison, & S.T.L., 2007). Its manufacturing processes are regarded as energy intensive and release significant amount of CO2 and heat into the atmosphere (Broderick, 2008). Next a little more detailed description of polyethylene’s
environment, animals, where does it go? There are 7 types of plastic according to Mercola; “Plastic #1: Polyethylene Terephthalate (PET) is things like water bottles and condiment containers, this plastic is listed as safe but can leach chemicals during production. Plastic #2: High-Density Polyethylene (HDPE) is used for milk, juice, and shampoo bottles, these are considered as a low level of toxicity. Plastic #3: Polyvinyl Chloride (PVC) these plastics are used for plastic wrap, plastic toys
The modern high fat diet commonly referred to as a ketogenic diet can be achieved in a manner not unlike a normal carbohydrate diet. Where roasts and salmon and vegetables are not just a normal part of the diet but essential. Though it is dangerous to start a ketogenic diet without a little bit of research. This is due to many essential nutrients that we normally source through plants such as wheat, potatoes, rice, and corn, which are extremely high in carbohydrate. With these foods being too high
Several researches investigated the benefits of knowing the genomic sequence and how it is associated with the risk of certain disease. There are several arguments contrary to genomic research and some are supporting it. For instance The Director of Cancer genetics center at Johns Hopkins university says “it may become one important determination in patient care, but certainly not the only one” [source]. Several studies doubts that genomic research providing any extra information about the possibility
Simvastatin Introduction Simvastatin is used to lower the cholesterol level in the blood such as the low-density lipoprotein (LDL) and triglycerides and to raise the high-density lipoprotein (HDL), It decreases the risk of heart diseases and helps to prevent the heart attacks and strokes by reducing the amount of cholesterol that is made by the liver (Raleys.com, 2015). Chemical structure and functional groups Simvastatin is one of the statins derivatives that is synthesised from a fermentation
Reading all of this might be a little bit difficult to understand however, if you do not know of the different types of cholesterol. The two main types, as found on WebMD, are “low-density lipoprotein cholesterol (LDL), also known as the “bad” cholesterol, and high-density lipoprotein cholesterol (HDL), also called "good" cholesterol” (“Understanding Cholesterol Numbers”). The weird factor about running is that while it does reduce the levels of LDL, it increases the levels of HDL. The American Heart
Blood pressure is the force exerted by the blood on the inner walls of the veins/vessels. In many cases, when blood pressure is too high a multitude of chronic diseases can occur such as heart disease, atherosclerosis, and negatively impact every blood vessel that travels around your body. According to your blood pressure results (High Blood Pressure stage 1 Hypertension), you are in the unhealthy range putting you at risk for these diseases and others like them. This can be a result of sedentary
