The Effects of Acid Rain on Living Organisms

1 January 2017

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done, the rainwater samples were tested using a pH meter.

The results of the pH test of rainwater in urban areas: in Novaliches, Quezon City, in Philcoa, Quezon City, in Katipunan, Quezon City, in Paco, Manila, and in Malate, Manila are between 6. 08 to 6. 10 The result of the pH test of rainwater in rural areas: in Iriga City, Bicol, in Buhi, Bicol, in Naga City, Bicol, in Calamba, Laguna, and in Binan, Laguna are between 5. 7 and 5. 8. There are different aspects that affected the results; these aspects will be further discussed in the Review of Related Literature part of Chapter I.

The results gathered were treated statistically using T-test to compare the pH level of the rain from urban areas and rural areas. From there, the researchers concluded that rainwater from rural areas is more acidic than the rain from urban areas. It is because rural areas are unpolluted while urban areas are drastically polluted. This research can help the people interested to know the acidity of rain from urban areas and rural areas. This can serve as their basis for further studies.

The amount of pollutants present in the atmosphere greatly affects the rain especially its pH level, which makes it less acidic or more acidic depending on how much pollutants are there in the atmosphere. Although the effects of acid rain are inconspicuous at first glance, it actually affects the surroundings due to the damage it brings. The consequence of acid rain is evident in man-made structures and natural surroundings. It corrodes paints, metals, and monuments and it also brings problems to farmers as it seeps in the soil which causes it to lose the nutrients plants need to grow.

The researchers would like to conduct their own experiment to find out the acidity of rain in certain parts of the Philippines. Knowing the damages it brings, the researchers would like to determine the how the exposure to air pollution affects the acidity of the rain. The purpose of this study is to find out which area has more acidic rain—rural or urban. Statement of the Problem, Objectives and Hypothesis Due to the industrialization in urban areas, it is more exposed to air pollution. According to some of the previous researches the amount of pollution present in the atmosphere affects the acidity of the rain in that certain area.

The researchers would like to know the acidity of rain in selected urban and rural areas in the Philippines. They would like to determine which of the two areas, urban or rural, is more subjected by acid rain. The study aims to: * determine the acidity of rain in selected urban and rural areas—Bicol, Laguna, Caloocan, and Metro Manila; * find out the aspects that affect the acidity of rain and to determine its indicators; and * Determine which area—urban or rural, is more subjected to acid rain from the data collected.

If the amount of pollution has an effect on the acidity of rain in certain areas, then the researchers came up with a wise guess that the rain in urban areas—which is more exposed to air pollution is more acidic than the rain in rural areas. Scopes and Limitations In view of the fact that the researchers are dealing with rain, there are aspects that have to be taken into consideration. The experiment that will be conducted will only be on acidity of rain and not any other components of rain. The experiment that will be conducted is limited only in determining the acidity of rain.

The pH level of acid rain will be determined by using a pH meter. Rain water that will be tested will only come from the selected areas in urban and rural places, namely Bicol, Laguna, Manila, and Quezon City. Five samples of rain water from the mentioned urban areas and five samples of rain water from the mentioned rural areas will be collected. This means that the result acquired are not guaranteed to be similar in other areas in the Philippines. Only rain collected from the said areas are part of the study, rain from other areas not mentioned is no longer part of the study.
