ways, the twelve principles of Green Chemistry can help minimize them. The twelve principles include prevention of waste, the design of less hazardous chemical syntheses, use of less toxic solvents and renewable feedstock, and design chemicals and products to degrade after use. These principles are seen in the making of synthetic organic chemical substances. 1 By changing techniques and applications of organic…

Question 1 What are the two major general types of chemical sources that result in human exposure to those chemicals and provide a simplified “total” human exposure model showing the pathways that determine the total human dose from those chemicals. The total Human exposure model Source: http://exposurescience.org/a-total-human-exposure-model-them Chemical sources Lead Drinking water. Industrial sources Mercury Manometers Electrochemical industries Fungicides (KAD,2002). drinking water…

stems and fruit, which is used to cut the tires used for papayas. For industry 2.3.1 Benefits of "papain" in the industry. 1) industrial products, beer, wine and other beverages will be served by papain dissolved protein in the product. The solution is clear and not cloudy or longer when stored at low temperatures. 2) the production of meat and fish to make the meat soft and tender when the cooking. 3) in the pharmaceutical industry and the medical benefits of the drug using a digestive aid. It…

technological and scientific advancements have enabled scientists and engineers to protect and benefit the economy, people and the planet through implementation of Green Chemistry. The American Chemical Society Green Chemistry Institute describes green chemistry as a different perspective on how chemistry and chemical engineering should be done to reduce waste, conserve energy, and utilize replacements for hazardous substances. Through a series of twelve principles, the ideals of Green Chemistry…

to fund clinical studies for public health and safety, to research potential risks of mental illness, and regulate publications about the relationship between medical and recreational cannabis. Cannabis may be defined as a psychoactive drug, a chemical substance that changes brain…

Phosphorus: General: Phosphorus is one of chemical elements of periodic table with atomic number 15 and atomic mass 30.9738 g/mol. Phosphorus is one of members of polyvalent non-metal of Nitrogen group and can be found in nature as some different allotropic format. Phosphorus can not be found free in nature since it’s so reactive and while it’s isolated and pure, it is clear and almost transparent. Phosphorus can be found in three common forms as white, red and black which their particular…

contains 0.1–4 µg/m3 Zinc is found in the air, soil, and water, and is present in all foods. zinc is a bluish-white shiny metal if it is in pure form. Zinc has many uses in industry in Metallic form. Alloys such as brass and bronze are form by mixing of metallic zinc with other metals. Zinc form salts as it combines with other chemicals. In nature, most zinc ore is found as the salt of zinc sulfide. Sphalerite (ZnS) a element is found in association with other base metals such as copper and…

correct industry. An industry has sub-parts. For example, if you look at the chemical industry, you will find sub-industries like Fertilizers, Pesticides, Paints and Varnishes, Organic chemicals. Therefore, it is important to focus on the relevant industry. Without this, it will be impossible to draw an accurate industry analysis report. It can also be time consuming if industry is done on all the parts of the industry. It is easier to take up an industry and find out the sub-industries. Select…

were fed into machines at one end of the industry were miraculously turned into edible oil at the other. The size and sound of huge machinery left me wondering what exactly was happening inside those pieces of equipment which converted raw materials into finished goods. This was the time I was introduced to the fascinating field of Chemical Engineering and the idea of pursuing the road…

and water. It has the chemical formula CH2O and its chemical structure is as shown in figure.1. Uses: Formaldehyde is used mainly in the production of plastics (such as urea-formaldehyde plastics which is used in many manufacturing processes due to its useful properties such as flexural modulus, and a high heat distortion temperature, high surface hardness, low water absorption, high tensile strength, mold shrinkage, elongation at break, and volume resistance), leather industry as an essential…
