Aromatic hydrocarbon

product. (g) Melting point determination is performed in order to assess the purity of the recrystallized product. Benzanilide, C13H11NO has a carbonyl group so placed as to make the compound a ketone along with a secondary amine group in between two aromatic benzene rings. This chemical composition give the molecule certain characteristics of both the non-polar and polar compounds. Thiourea, a thioketone, SC(NH2)2, has a sulfur double-bonded to a carbon that is connected to two primary amine…

Background Info. Santa barbara is a city on the central California coast. The population in Santa Barbara from 2013 was 90,412. Santa Barbara is known for many things, but one in particular is its arts, and how it has aspired artist for generations. It all started approximately 13,000 years ago, when the first native americans arrived. With this there were many impacted events of Santa Barbara, the Mission period, The rancho period, The victorian period (SARC), The Earthquake of 1925, and the…

4. Uptake and bioaccumulation of plastic derived chemicals A key factor contributing to the bioavailability of microplastics is their small size, density, color, surface (smooth or rough) (Stephanie L. Wright a,2013). Food chain disturbance in marine environment is the major problem because due to ingestion of plastic which consists of polychlorinated biphenyl (PCB), POP and PAH. They absorbs/bioaccumulation in the fatty acid of living organism and cause death of the species. At least 180…

The immune system is the primary and essential protective mechanism against different organisms. Aflatoxin B1, a secondary metabolite of fungi, impairs the immune system. However, the mechanisms responsible for the immunomodulating effects of aflatoxin B1 have not been clearly determined. Numerous studies reported that aflatoxin B1 exerts its toxicity on the immune system by different mechanisms. Inhibition of the aforementioned synthesis might directly or indirectly cause prevention of…

water system becoming contaminated and unsafe to drink” (http://www.ran.org/chevrons-toxic-legacy-ecuador). “Two of the most dangerous chemicals to humans are found in the water in lethal concentrations these chemicals are benzene and polycyclic aromatic…

types of tattoo inks, azo dyes and metal salt ink. The most typical ink being used is the metal salt ink. Metal salt pigments contain metals like cobalt, cadmium, dichromate and mercury. Black pigment contains carbon black with polycyclic aromatic hydrocarbons. The black pigment is known for causing most allergic reactions and numerous skin problems [8]. White, black, and violet colors contain the least amount of inorganic components, which could explain why black and blue pigments are commonly…

Smoking Bans By: Nathaniel, Alexis, Devyn, and Logan We see people smoking, everywhere; in their cars, at their house, in bars, outside, at parks, almost anywhere at almost any time. We see our dad smoking a pipe on the couch, we see our friends mom smoking at the park, we see our own family and friends with cigarettes in hand puffing away. Smoking bans are set to help save the lives of smokers, non-smokers, and the environment around us. Smoking harms the human body in many ways. Although some…

Introduction: The name Pseudomonas is derived from the greek and latin words which means “false unit“ (pseudo = false, greek; monas = single unit, latin). “Monas” was used in the early history of microbiology to define single-celled organisms. In 1786 Otto Friedrich Müller, from Copenhagen, classified the bacteria and named the pseudomonads, they came into the group of vibriones (which was defined as group of shaking bacteria). Many years later it was detected that Pseudomonas are motile. They…

mineral oil): Because petrolatum is derived from petroleum (oil), it needs to be refined, and some refining methods use toxic compounds. If the petroleum jelly becomes contaminated during the manufacturing process, possible PAHs (polycyclic aromatic hydrocarbons) and other carcinogenic agents may get into the jelly. PAHs are considered potentially carcinogenic and have links to breast cancer. Any traces of PAHs are supposed to be removed at the end of the refining process. The European Union…

Carcinogenic Chemical Product: Fire Retardants Fire safety is a vital part of the modern technological society and as responsible citizens it is important to recognise that, with the aid of fire retardants, there is a prolong time frame of escaping from fires. This widely used carcinogenic product is composed of certain chemical elements within numerous everyday products (either inside the polymeric material or as an external layer) that help combat the ignition through chemical reactions at…
