2、How did acid rain (酸雨)affect the plant

General Information Acid rain (or more accurately acid precipitation)[1] occurs when sulfur dioxide and nitrogen oxides are emitted into the atmosphere

undergo chemical trformations and are absorbed by water droplets in clouds. The droplets then fall to earth as rain

snow

or sleet. This can increase the acidity of the soil

and affect the chemical balance of lakes and streams.[2] The term "acid rain" is sometimes used more generally to include all forms of acid deposition - both wet deposition

where acidic gases and particles are removed by rain or other precipitation

and dry deposition removal of gases and particles to the Earth's surface in the absence of precipitation.[3] Acid rain is defined as any type of precipitation with a pH that is unusually low.[4] Dissolved carbon dioxide dissociates to form weak carbonic acid giving a pH of approximately 5.6 at typical atmospheric concentrations of CO2.[5] Therefore a pH of less than 5.6 has sometimes been used as a definition of acid rain.[6] However

natural sources of acidity mean that in remote areas

rain has a pH which is beeen 4.5 and 5.6 with an average value of 5.0 and so rain with a pH of less than 5 is a more appropriate definition.[7] The US EPA says

"Acid rain is a serious environmental problem that affects large parts of the US and Canada" [8] Acid rain accelerates weathering in carbonate rocks and accelerates building weathering. It also contributes to acidification of rivers

streams

and forest damage at high elevations. Adverse effects Soils Soil biology can be seriously damaged by acid rain. Some tropical microbes can quickly consume acids[11] but other types of microbe are unable to tolerate low pHs and are killed. The enzymes of these microbes are denatured (changed in shape so they no longer function) by the acid. The hydronium ions of acid rain also mobilize toxins and leach away essential nutrients and minerals [12]. [edit] Forests and other vegetation Acid rain can slow the growth of forests

cause leaves and needles to turn brown and fall off and die. In extreme cases trees or whole areas of forest can die. The death of trees is not usually a direct result of acid rain

often it weakens trees and makes them more susceptible to other threats. Damage to soils (see above) can also cause problems. High altitude forests are especially vulnerable as they are often surrounded by clouds and fog which are more acidic than rain.[12] Other plants can also be damaged by acid rain but the effect on food crops is minimised by the application of fertilizers to replace lost nutrients. In cultivated areas

limestone may also be added to increase the ability of the soil to keep the pH stable

but this tactic is largely unusable in the case of wilderness lands.[12] Acid Rain depletes minerals from the soil and then it stunts the growth of the plant. 落埋subtitle架啦，應該幾易睇，凈系節錄左introduction同有關(guān)effect to the plant比你，其余可以去en. *** /wiki/Acid_rain#Forests_and_other_vegetation睇

參考: Webpage

Acid rain can perate into the soil can mix with water

when the plant absorb water from the soil

the acid in water will affect the enzyme acticity

like photosynthesis and respiration since they are controlled by enzyme. Also

the concentration of water molecules in the water containing acid is lower than the water inside the leave cells

and the water willmoves out through the cell membrane by o *** osis

with these effect on the plant

the plant will therefore die ! 2006-12-03 19:32:22 補充： The acid will affect the soil and the root of the plant cannot absorb minerals in the soil normally

and this will also decrease the nutrients supply to the plant.

streams

and forest damage at high elevations. Natural emissions The principal natural phenomena that contribute acid-producing gases to the atmosphere are emissions from volcanoes and those from biological processes that occur on the land

in wetlands

and in the oce. The major biological source of sulfur containing pounds is Dimethyl sulfide. The effects of acidic deposits have been detected in glacial ice thousands of years old in remote parts of the globe. [edit] Human emissions The principal cause of acid rain is sulfur and nitrogen pounds from human sources

such as electricity generation

factories and motor vehicles. The gases can be carried hundreds of miles in the atmosphere before they are converted to acids and deposited. [edit] Gas phase chemistry In the gas phase sulfur dioxide is oxidized by reaction with the hydroxyl radical via a termolecular reaction: SO2 + OH· → HOSO2· which is followed by: HOSO2· + O2 → HO2· + SO3 In the presence of water sulfur trioxide (SO3) is converted rapidly to sulfuric acid: SO3 + H2O → H2SO4 Nitric acid is formed by the reaction of OH with Nitrogen dioxide: NO2 + OH· → HNO3 For more information see Seinfeld and Pandis (1998).[5] [edit] Chemistry in cloud droplets When clouds are present the loss rate of SO2 is faster than can be explained by gas phase chemistry alone. This is due to reactions in the liquid water droplets Hydrolysis Sulfur dioxide dissolves in water and then

like carbon dioxide

hydrolyses in a series of equilibrium reactions: SO2 (g)+ H2O ⇌ SO2·H2O SO2·H2O ⇌ H++HSO3- HSO3- ⇌ H++SO32- Oxidation There are a large number of aqueous reactions of sulfur which oxidise it from S(IV) to S(VI) leading to the formation of sulfuric acid. The most important oxidation reactions are with ozone

hydrogen peroxide and oxygen (reactions with oxygen are catalysed by Iron and Manganese in the cloud droplets).
