Experimental section Synthesis of dimethyl tetraphenyl phthalate In a small reaction tube, the tetraphenylcyclopentadienone (0.110 g, 0.28 mmol) was added into the dimethyl acetylene dicarboxylate (0.1 mL) and nitrobenzene (1 mL) along with a boiling stick. The color of the mixed solution was purple. The solution was then heated to reflux until it turned into a tan color. After the color change has occurred, ethanol (3 mL) was stirred into the small reaction tube. After that, the small reaction
enabling the development of cancer (Site 1). Of all the possible EDCs, phthalates seem to be one of the best-studied and most habitually encountered EDC. According to a study that investigated EDCs and asthma-associated chemicals in consumer products, phthalates are commonly used as solvents in personal care products, adhesives, detergents, lubricants, as well as pesticides despite the short
The move has had an alarming statistic because some of the chemicals that are contained in the plastic water bottles have been recently proven to be harmful for the human consumption. The two types of chemicals that are particularly harmful are phthalates and biphenyl-A which are used to make the plastic bottles flexible. The use and manufacturing of plastic water bottles has negative consequences for humanity because it has health risks, is damaging to the environment, and is a waste of fossil fuels
PVC in the Environment Producing PVC requires the use of chlorine gas. PVC ranks the third in both global plastic output and consumption. Over 33 million tons of PVC is being produced each year and that figure is increasing annually. Around 57% of PVC’s mass is chlorine, so it requires less petroleum than many other polymers. (Thornton, 2002) PVC is strong, resistant to oil and chemicals, sunlight, weathering and flame resistant. It’s everywhere around us. PVC is an incredibly versatile material

Phthalates are industrial chemicals, which soften plastics that are used to make common consumer products including fragrances, cosmetics, plastics, and building materials. Phthalates are endocrine-disrupting chemicals; exposure has been linked to early puberty, a risk factor for later-life breast cancer; reproductive
should breastfeed your baby or use powdered formula instead of cans. Avoid bottles and plastic containers that are made from polycarbonate (usually marked with a number 7 or the letters PC as seen in fig. 1) and if you want to reduce exposure to phthalates, avoid polyvinyl chloride (marked with a number 3 or PVC as seen in fig.1).

pregnancy, the ingredients in makeup can be lethal to the fetus. Nail polishes and hair sprays contain substances called phthalates, which is more commonly known as a plasticizer and can be found in the material to make rain coats and garden hoses, and its purpose is to make plastic more flexible but still strong (“Controversy Over Phthalates in Cosmetics” par 1) .When phthalates are absorbed into the skin, they could harm the fetus and, in baby boys, they could cause irregular genitals. Another ingredient

However, by giving the surveys, I know that not too many people know that medicine contains some harmful materials which can accumulate in the human body and influence apparatus indirectly.

worth mentioning. In 2013, Limited Brands committed to erase hazardous chemicals out of its global supply chain in response to Greenpeace´s Detox campaign. A 2012 investigation revealed a hormone-disrupting phthalate in underwear sold in Victoria´s Secret stores in the United States. (Phthalates and perfluorinated chemicals (PFCs) are man-made chemicals that contain non-stick and water-repellent properties. These chemicals can affect the liver, disrupt hormones and alter growth). According to Greenpeace’s
helps to dissolve other chemical substances contained in products such as shampoos. Second role is as penetration enhancers of water in the skin. Another characteristic of phthalates is their ability to act as plasticizers, which are able to increase the flexibility of plastics. (2015 as cited in Koniecki et al. 329-336). Phthalates are used in a wide range of personal care products as body and hand lotion, hair products, deodorants, nail polish, lipsticks, colognes and perfumes. According to studies
The plastic the bottles are made from is softened with chemicals called phthalates. When exposed to heat, such as being left in a hot car, these phthalates may be released contaminating the water. These phthalates act like hormones and disturb the endocrine system (ie. pancreas, ovaries, testes, thyroid gland). (Parsons) Another risk is antimony, a dangerous chemical used in making water bottles
assessing their exposure to these dangerous chemicals that are found in the products that we use to continue with our daily lives. They publish their results and find that phthalates, PFOA and PCBs are both dangerous to human health and the environment. Background The environmental health problems described in this book are that phthalates, PFOA and PCBs are dangerous chemicals. We are exposed to these chemicals on a daily basis and they are common household products and hygienic products. We are also

Most of the necessities humans need are provided in supermarkets, in fact supermarkets have become a necessity for our everyday life. They are now the main source of water, food, clothes and everyday tools. Therefore, the plastic bags demanded and supplied in this industry increase every day. In the past decade, we produced as much plastic as we did in the whole twentieth century (Freinkel, 2011). This exponential increase of a non-biodegradable material has negatively impacted our environment immensely
Bottled Water is not only dangerous to your environment, but to you and your body as well. There are many myths that accompany this topic, but the purpose of this paper is to give the clear cut facts on an important issue. Aside from it’s dangers to your wallet, its affects on your body and environment are astonishing. For years bottled water has been viewed as a convenient and “safe” alternative to lugging around a big thermos or drinking the water from your tap. In reality, actual safe alternatives
Do environmental factors play a role in causing autism? Even though the concept and occurrence of autism is intricate, with both hereditary and external factors, it is evident through several researchers that immune system of a person plays a significant role in the causation of autism. Some of the components that influence autistics person’s immune health are related to his prenatal and postnatal environment in which he lives, including his regular food intake chiefly. These factors combine to
Abstract: Luminol, known for it’s use in crime labs to identify blood, was one of the main components used in the experiment which sought to use a starting material, convert it to a product, and then use the product as the starting material for an alternate reaction. In the experiment conducted in lab, 5-nitro-2,3-dihydropthalazine-1,4-dione was used as starting material, and when the nitro group was added to sodium hydrosulfite in 3M sodium hydroxide in water it was reduced and the resulting amine
Best Protein Shaker Protein is best when it is sourced from whole foods, but if you’re not able to get the entire daily protein requirement from food, you can get it from protein powders. Protein powders can serve as an alternate meal or as a post-workout supplement. Protein powders are convenient and can be easily absorbed and digested when compared to whole foods. The best protein shaker should be able to suit your protein drinks. In order to maximize the potency of your protein powder, the best
is part of a social construct of beauty that women have been compelled to follow for many years. While beautifying could be hard to see as dangerous, recent studies have confirmed that cosmetics actually contain harmful chemicals such as paraben, phthalates, petrochemicals, artificial fragrances, sodium lauryl sulfate, and diazolidinyl urea, which have been linked to causing cancer, reproductive health issues, and birth defects. Although the exposure of these chemicals is in very small quantities at
