Yes it is only in places that are polluted. But don't worry the news or somebody will get a message out telling people not to go outside.

Rain water but not acid rain water.  Since I don't get a lot of rain in my state I usually used purified water mixed with miracle grow.  If you want your plant to grow faster make sure you give it enough light as well.

The individual drops of rain usually form as pure drops of water.  As these drops fall, they encounter gases in the atmosphere which can be absorbed and react with the water.\n\nMost of the gases are oxides of nonmetal elements.  When they react with water, they form acids.  This is the source of "acid rain."\n\nFor example Nitrogen dioxide reacts with water to form nitric acid.

Acid rain can cause erosion on ancient and valuable statues and has caused considerable damage. This is because the sulfuric acid in the rain chemically reacts with the calcium in the stones (lime stone, sandstone, marble and granite) to create gypsum, which then flakes off. This is also commonly seen on old gravestones where the acid rain can cause the inscription to become completely illegible.\n\nThe toxic ions released due to acid rain form the greatest threat to humans. Mobilized copper has been implicated in outbreaks of diarrhea/diarrhoea in young children and it is thought that water supplies contaminated with aluminium cause Alzheimer's disease.\n\nTrees are harmed by acid rain in a variety of ways. The waxy surface of leaves is broken down and nutrients are lost, making trees more susceptible to frost, fungi, and insects. Root growth slows and as a result fewer nutrients are taken up. Toxic ions are mobilized in the soil, and valuable minerals are leached away or (as in the case of phosphate) become bound to clay.\n\nAcid rain also causes an increased rate of oxidation for iron

Well it's in the tropics.  It rains a lot.  And it's a forest.  Hmmm... Not sure.

Towards the equator, where it doesn't rain too much!  Just kidding.  What exactly do you want to know?

Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing off insect and aquatic lifeforms as well as causing damage to buildings and having possible impacts on human health.\n\n\nSurface Waters and Aquatic Animals:\n\nBoth the lower pH and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals. At pHs lower than 5 most fish eggs will not hatch and lower pHs can kill adult fish. As lakes become more acidic biodiversity is reduced. Acid rain has eliminated insect life and some fish species, including the brook trout in some Appalachian streams and creeks.\n\n\nSoils:\n\nSoil biology can be seriously damaged by acid rain. Some tropical microbes can quickly consume acids 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.\n\n\nForests and other vegetation:\n\nAcid 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.\n\nOther 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. Acid Rain depletes minerals from the soil and then it stunts the growth of the plant.\n\n\nHuman health:\n\nSome scientists have suggested direct links to human health, but none have been proven. However, fine particles a large fraction of which are formed from the same gases as acid rain (sulfur dioxide and nitrogen dioxide) have been shown to cause illness and premature deaths.\n\n\nOther adverse effects:\n\nAcid rain can also cause damage to certain building materials and historical monuments. Acid rain can cause erosion on ancient and valuable statues and has caused considerable damage. This is because the sulfuric acid in the rain chemically reacts with the calcium in the stones (limestone, sandstone, marble and granite) to create gypsum, which then flakes off. This is also commonly seen on old gravestones where the acid rain can cause the inscription to become completely illegible. Acid rain also causes an increased rate of oxidation for iron. Visibility is also reduced by sulfate and nitrate in the atmosphere.

What is?\n\nAcid rain" is a broad term used to describe several ways that acids fall out of the atmosphere. A more precise term is acid deposition, which has two parts: wet and dry. \n\nWet deposition refers to acidic rain, fog, and snow. As this acidic water flows over and through the ground, it affects a variety of plants and animals. The strength of the effects depend on many factors, including how acidic the water is, the chemistry and buffering capacity of the soils involved, and the types of fish, trees, and other living things that rely on the water. \n\nDry deposition refers to acidic gases and particles. About half of the acidity in the atmosphere falls back to earth through dry deposition. The wind blows these acidic particles and gases onto buildings, cars, homes, and trees. Dry deposited gases and particles can also be washed from trees and other surfaces by rainstorms. When that happens, the runoff water adds those acids to the acid rain, making the combination more acidic than the falling rain alone.\n\nPrevailing winds blow the compounds that cause both wet and dry acid deposition across state and national borders, and sometimes over hundreds of miles.\n\nRead:http://www.fs.fed.us/ne/newtown_square/aboutus/history.shtml\n\nhttp://www.nautilus.org/archives/fora/energy/9704A_VonHippel.html\n\nee this Epa report:http://www.epa.gov/airmarkets/cmprpt/arp03/summary.html

limestone minerals buffer the acid rain.  The acid reacts with the calcite, etc. in limestone and changes it to more neutral or even slightly basic.  Our groundwater, therefore, tends to have a higher pH even though the pH of rainwater is low.

Rainwater will have a pH determined by its composition.  Its composition will be water (pH=7), O2, CO2, SO2, NOx,... stop me when I've mentioned something that strikes you as a product of human pollution.  There are some ultra left wing radical commie pinko pseudo scientists who LIE about pollution and say it is a GLOBAL problem.  But WE all know that we can fowl our rivers and burn our forests and nothing will be affected more than oh a couple of feet away, right?  RIGHT?!! Tha tha thats all folks.

India's Red Rain Analysis Report \n[Original headline: Red rain was fungus, not meteor’]\nTHIRUVANANTHAPURAM, India: The red rain that lashed parts of Kerala last month is eluding explanations as the days go by.\n\nThe Centre for Earth Science Studies (CESS) here on Saturday retracted its hypothesis that a streaking meteor triggered the rain. \n\nEverybody had taken that explanation with a pinch of salt because other researchers had spoken of biological contents in the water samples. Yet, the retraction has raised eyebrows about a premier research body’s prudence in making a hurried announcement. \n\nCESS has not only retracted, but tagged a confession: ‘‘This leaves several questions unanswered.’’ The CESS press release was triggered by the chemical analysis of the water samples that showed these were largely biological. Biological studies have identified organic material such as fungal spores in them. \n\nCESS director M. Baba said: ‘‘The exact species is yet to be identified. But how such a large quantity of spores could appear over a small region is as yet unknown.’’ \n\nOn July 25, Changanacherry town had received the coloured showers overnight that continued into the morning and on till sunset. Some residents collected samples of the rain. They said the shower was accompanied by thunder and lightning. \n\nCESS then collected the samples and tested them. The water was found to be neutral and contained some amount of dissolved salts. \n\nThe filtered precipitate was fine and powdery, and this, said Baba, was chemically and biologically analysed. \n\nThe chemical analysis showed various elements — including carbon, silicon, calcium, magnesium, aluminum, iron, sodium and potassium. It contained significant traces (in parts per million) of phosphorus, titanium, chromium, manganese, copper and nickel. \n\nThe biological study — partly conducted at CESS and at the Tropical Botanic Garden and Research Institute (TBGRI), Pacha Palode — revealed a red coloured cell structure. \n\nThis has been tentatively identified as spores of some fungus species and are now being cultured by the TBGRI. ‘‘The red colour of the rain appears to be mainly because of the spores,’’ Baba said. \n\nThese findings, say CESS, raise doubts on whether the explosive sound reported by residents and the red rain were independent events. There are other posers too which remain unanswered: \n\nWhat produced the huge quantity of spores ? Is the source local or distant? \n\nHow were the spores injected into the clouds? \n\nIf the source is not local, how was the mass transported without getting distributed over a large area? \n\nBy way of an answer, CESS has only this to say : ‘‘While the cause of the colour in the rainfall has been identified, finding the answers to these questions is a challenge.’’ \n\n• Story originally published by: \nThe India Express | Kamal Gopinath Nair - Aug 6 2001
