Combustion of organic compounds can result in detrimental impacts on the environment such as the generation of acids and production of carbon monoxide, particulates and soot. When organic compounds that contain sulphur, nitrogen are combusted, the reaction may produce gases such as sulphur dioxide, nitrogen dioxide and carbon dioxide. When these compounds react with water molecules, it will produce acids which fall as acid rain.Acids dissolve calcium carbonate, meaning that monuments made from marble and limestones are particularly vulnerable. In environmental terms, acid rain flows into water bodies. Acid rain releases aluminium from the soils into the water, an element which is highly toxic to many species of aquatic organisms.
1. Using what you know about the chemical makeup of stomach contents and the control of food moving through the GI tract, provide a reason some people get heartburn. What is actually happening to cause this burning sensation in the chest? * Heartburn is an acid reflux. Acid reflux can happen when the esophagus opens at the wrong time during digestion and the acid from the stomach hitting the esophagus causes a burning sensation.
A dangerous cargo manifest is most commonly associated with which mode of transportation? (1 point) C. Water 19. What chemical agents primarily attack the airway and lungs, causing irritation of the entire airway from the nose to the lungs and resulting in what is commonly known as dry-land drowning? (1 point) C. Choking (CL) 20.Identify one of the difficulties of determining the specific names of hazardous materials in both facilities and transportation. (1 point) B. Placards or labels that are missing 21.Individuals should use the principles of __________, __________, and __________ to avoid chemical agents.
Hydrogen peroxide is a poisonous chemical to all living things. Catalase converts H 2O 2into 2 separate harmless substances, water and oxygen. In this experiment we will be testing the effects of temperature, pH and substrate concentration on Catalase. The optimum pH of catalase is 7 and its optimum temperature is 37 degrees. Aim: To test the effect of change in pH, Temperature and substrate concentration on catalase in liver Hypothesis: we predict the enzyme will have its greatest reaction when it is in its optimum temperature, pH and substrate concentration Risk assessment: * Wear gloves when handling raw liver.
Renal causes affect the kidney directly, they include sepsis (when the immune system is overwhelmed by infections which causes the kidney to shut down), medication which are toxic to the kidney e.g. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen (Advil, Motrin, and others) etc. lastly the post- renal causes include, obstruction of the bladder; the kidney produces more urine but due to the obstruction it acts like a dam instead of emptying and soon forces the kidney to shut down and kidney stones which only causes the disorder if only one kidney is present. The main cause of this conditions is the accumulation of waste products in the kidney. In some cases kidney failure can be treated and they can go back to normal
It also have some very harmful effects on humans and nature. It creates large amount of pollution, destroys the nature and also increases the diseases in human societies. As in documentary about “The Ethics of Fracking” by Marleen troy PhD (Environmental Engineer), Bernard Prausak and Rabbi Mordechai Liebling.
Consequences The most conspicuous effect of cultural eutrophication is the creation of dense blooms of noxious, foul-smelling phytoplankton that reduce water clarity and harm water quality (Figure 2). Algal blooms limit light penetration, reducing growth and causing die-offs of plants in littoral zones while also lowering the success of predators that need light to pursue and catch prey (Lehtiniemi et al. 2005). Furthermore, high rates of photosynthesis associated with eutrophication can deplete dissolved inorganic carbon and raise pH to extreme levels during the day. Elevated pH can in turn ‘blind' organisms that rely on perception of dissolved chemical cues for their survival by impairing their chemosensory abilities (Figure 3) (Turner & Chislock 2010).
The different uses will depend on the food being irradiated as each technology has strengths and weaknesses. Gamma ray irradiation is very powerful and can penetrate substances deeply. It also yields substantial uniformity of the does in the product and decays to non-radioactive nickel. But the radioactive source, commonly Cesium-137, requires frequent replenishment and treatment of the food is relatively slow. Additionally, protective barriers must be in place when this form is used to protect workers and the environment.
The reason why this happen is some people’s body is will produce antibodies to against the protein in some foods which will trigger reactions and cause hives, swelling around the mouth, diarrhea, vomiting and itchiness. Sometimes it can cause more serious and dangerous reactions such as hard breathing, swelling in throat, dizziness or collapse which can cause the person to death. A report shows that 7 deaths cause by food anaphylaxis was found during
Spatial, vertical and temporal variations of elemental mercury and human exposure to deadly effects of methyl-mercury are also presented in this study. Ishan Joshi 2 1. Introduction: Mercury occurs naturally in the Earth’s biochemical system. It is a highly volatile trace metal. Before an industrial
