Toxicity

Synthetic Dye Assignment Dye: Sunset Yellow FCF Caitlin Walker Sunset Yellow FCF, more commonly known as Yellow 6, is an orange azo dye3. This dye is petroleum-derived and its absorption is dependent on the pH. Minimum absorption occurs at 480 nm with a pH of 1 and maximum absorption occurs at 443 nm with a pH of 13. Sunset Yellow FCF is soluble in cold water2. Sunset Yellow FCF has the following structure (Figure 1). Sunset Yellow FCF is commonly used in food, cosmetics, and drugs. It is…

In the last several years, much debate has been raised over the issues of child vaccinations here in the U.S. Various studies have yielded results that support both sides of the debate. At stake, is whether a parent can choose vaccines for their children, a decision that ultimately may protect the child, hurt the child, or possibly put others in the community at risk. Upon thorough factual research, a parent has a more informed to choose which vaccines should be administered to their child…

air pollution on a global level. Also, discarded cigarette butts pose a major problem for animals and even small children. In a peer review journal called Tobacco Control (2011), the toxicity problem with cigarette butts is discussed in depth. “Nicotine found in cigarette butts may cause vomiting and neurological toxicity; leachates of cigarette butts in aquatic environments may cause exposure to additional toxic chemicals including heavy metals, ethyl phenol and pesticide residues.” When it…

A study was able to identify major problems that would arise from Adderall toxicity when they examined 3 dogs that ingested large amounts of Adderall. It was identified that clinical signs of overdose of Adderall in human include hyperthermia, tachycardia, tachypnea, mydriasis, tremors, and seizures. These can lead to permanent…

Chances of accumulating heart disease are increased dramatically with the long-term abuse of steroids. Liver toxicity in relation to steroid use is caused when ingesting steroids. This is because the full dosage of testosterone must be passed through the liver before continuing circulation. Liver tumors in connection to steroid use are very uncommon and only appear…

drainage, groundwater seepage, and swimming pool filter backwash water” to surfaces water (Waste Discharge, 2014). Such discharges originally have the potential to cause an excursion above the water quality objectives, and lead to sudden or chronic toxicity in state water, because the wastewater may be polluted by contaminants, such as volatile organic compounds and heavy metals. In conclusion, discharge of non-process wastewater may threaten existing beneficial surface…

On September 11, 2001, the United States of America experienced the worst terrorist attack on record. Members of an al-Qaeda terrorist group hijacked four U.S. airplanes midair and used them as weapons to strike various targets. The Twin Towers (also referred to as the World Trade Centre) located in lower Manhattan, New York City were struck with two of the hijacked planes killing nearly three-thousand people and injuring many more. The impact of the collision caused the building to ignite and…

PART 2 Article 1: Researchers disguise drugs as platelets to target cancer 1) Describe the structure of the nanoparticle, including what it is composed of and what it contains inside and possesses on the outside. Inside there is a synthetic core nanogel. On the outside it possesses a platelet membrane shell. The TRAIL is attached on the surface of membrane and Dox is loaded in the core of nanogel. ( Hu, 2015 para. 1) 2) Explain the mechanism of how the nanoparticle system delivers the drug to…

demonstrate the cause of inaccurate and varied results. An experiment was conducted by comparing the results of 281 human ocular toxicity exposures to 14 house products with findings from the Draize test. The closest connection with the human experiences and the Draize test was a factor of 18 however the largest was 250. Therefore the Draize test poorly predicted the human eye toxicity (Kaufman, 2005). The scoring of the rabbit’s eye and skin damage is highly subjective therefore results…

Chemically treated food or sometimes referred to as conventional foods are grown using synthetic chemicals such as fertilizers and pesticides, which then get absorbed into the soil and cannot be removed. With the high demand for food as a result of population growth and improvements in human diets the demand for quality fruits and vegetables are rapidly on the rise. As expressed in Doreen Gabriel, article, Food Production Vs. Biodiversity, even though conventional agriculture is intensive it…
