One city maybe heavily affected while the other has n’t been affected. Acid rain causes shocking effects in natural lakes and the ecosystem. When, mercury (coal contains Mercury and when it is burned it is released into the atmosphere with carbon dioxide interrupts the water cycle midway by getting into the water vapours in the atmosphere) mixes with the blood and tissues of fish, it causes them to have high acidic levels. Which, will poison them and they will in due course die. Trees too are a victim of acid rain.
Some natural causes for these chemical reactions include erupting volcanoes and rotting vegetation. Eruption of volcanoes can release certain chemicals that react with the rain, and it’s the same case with rotting vegetation. These reactions usually release nitrogen oxides and sulfur oxide. This can be deposited in two ways, dry and wet deposition. Wet deposition is acid rain falling directly into the ground where the area is usually wet in rain, snow, or hail.
Acid Rain & Volcanoes Research Activity Acid Rain & Volcanoes Research Activity Task 1: Report on acid rain and its effects on the environment. Rain is usually slightly acidic. This is because when the rain falls is reacts with the carbon dioxide in the atmosphere therefore making the rain slightly acidic (ph of 5.6). When water reacts with gases such as Sulfer Dioxide or Nitrogen Oxide it produces Sulfuric Acid and Nitric Acid. This is called Acid Rain.
Course # Student name / Names of members of group Date: Exp # : Estimating the effects of acid rain Introduction: Precipitation that measures a pH value below 5.6 is generally considered as acid rain. Burning fossil fuels is the main reason for the elevated levels of gaseous oxides in a polluted atmosphere that in-turn forms acid rain. Gaseous oxides such as that of carbon, sulfur, nitrogen and phosphorus could dissolve in water to form an acidic solution. A generalized reaction sequence on the formation of acid rain is as follows; One of the determinants of clean water in the natural environment is its alkalinity. Alkalinity can be defined as the capacity to neutralize acids.
al.). Some pollutants – for instance, polycyclic aromatic hydrocarbons – can lead to life-threatening diseases in humans and wildlife, such as cancer (Harvey). Scientists use many different methods to remove these pollutants from water supplies; one of those methods is the utilization of adsorption onto a porous substance, normally charcoal. Due to numerous circumstances, scientists have begun searching for alternatives to charcoal, one of them being Bentonite clay. However, Bentonite clay cannot be easily removed from the water, so in this project the students were instructed to modify the clay to make it magnetic and then compare its effectiveness in absorbing a model PAH against charcoal.
They are not telling you all there is that you should know about though. The real deal on what’s on the inside of these so-called protective sanitary napkins - the chemical compounds called dioxins. What are Dioxins? Dioxins are a group of chemicals considered hazardous pollutants. These can occur through combustion processes such as when a forest is burned.
Mirrored Flask RESEARCH: * The Mirrored Flask, is a demonstration that consists of mixing aqueous silver nitrate with aqueous ammonia to produce a solution known as Tollens’ reagent. The term Tollen reagent comes from the Tollen's Test, which is another name for the Silver Mirror Test. When this reaction occurs the flask in which it is contained, changes from a transparent looking glass to a dark reflective material that is very much alike to a mirror. * Silver nitrate is a corrosive, which means it causes burns, stains skin and clothing, and is highly toxic. Ammonium hydroxide is dangerous to breathe, it’s extremely toxic if ingested, and causes skin, eye and respiratory irritation.
Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain". The release of sulphur dioxide can also occur naturally when a volcano erupts. How acidic is acid rain?
Air pollution comes from a wide variety of sources * Vehicle or manufacturing exhaust * Forest fires, volcanic eruption, dry soil erosion * Building construction or demolition Many scientists believe that global warming is also related to increased air pollution. 2. Water Pollution Water pollution involves any contaminated water, whether from chemical, particulate or bacterial matter that degrades the water’s quality and purity. It can occur in oceans, rivers, lakes and underground reservoirs. Causes of water pollution include: * Increased sediment from soil erosion * Improper waste disposal and littering * Leaching of soil pollution into water supplies The effects of water pollution include decreasing the quantity of drinkable water available, lowering water supplies for crop irrigation and impacting fish and wildlife that require water of certain purity for survival.
Significance of the Study Oyster shells are one of the many household garbage that affixes the long trails of unmanned wastes that threaten the ecology. Oyster shell deposits a lot of CaCo3 (calcium carbonate) in it, which have many used in the environment and one of this is being a pH buffer. The presence of hydrogen (pH) buffers maintains the pH of a substance, either by increasing or decreasing its pH. They are very important and helpful nowadays because of the rapid change of our environmental nature includes the creation of acid rain. Acid rain is one of the major effects of the accumulation of toxins and acids emitted and formed by human activities such as burning fossil fuels that threatens not only the people of the society but also the environment itself specially the bodies of water lying in it which directly harms all the creatures living in it because of the sudden changes in the environment, the sudden changing pH (presence of hydrogen) in the body they are living.
