Itis caused by today’s industry. When products are manufactured many chemicals areused to create it. However because of the difficulty and cost of properlydisposing of these products they are often emitted into the atmosphere withlittle or no treatment. The term was first considered to be important about 20 years ago whenscientists in Sweden and Norway first believed that acidic rain may be causinggreat ecological damage to the planet.

The problem was that by the time that thescientist found the problem it was already very large. Detecting an acid lake isoften quite difficult. A lake does not become acid over night. It happens over aperiod of many years, some times decades.

The changes are usually to gradual forthem to be noticed early. At the beginning of the 20th century most rivers/lakes like the riverTovdal in Norway had not yet begun to die. However by 1926 local inspectors werenoticing that many of the lakes were beginning to show signs of death. Fish werefound dead along the banks of many rivers. As the winters ice began to melt offmore and more hundreds upon hundreds more dead fish (trout in particular) werebeing found.

It was at this time that scientist began to search for the reason. As the scientists continued to work they found many piles of dead fish, up to5000 in one pile, further up the river. Divers were sent in to examine thebottom of the rivers. What they found were many more dead fish. Many live anddead specimens were taken back to labs across Norway. When the live specimenswere examined they were found to have very little sodium in their blood.

This istypical a typical symptom of acid poisoning. The acid had entered the gills ofthe fish and poisoned them so that they were unable to extract salt from thewater to maintain their bodies sodium levels. Many scientist said that this acid poising was due to the fact that it wasjust after the winter and that all the snow and ice was running down into thestreams and lakes. They believed that the snow had been exposed to many naturalphenomena that gave the snow it’s high acid content. Other scientists were notsure that this theory was correct because at the time that the snow was added tothe lakes and streams the Ph levels would change from around 5.

2 to 4. 6. Theybelieved that such a high jump could not be attributed to natural causes. Theybelieved that it was due to air pollution.

They were right. Since the beginningof the Industrial revolution in England pollution had been affecting all thetrees,soil and rivers in Europe and North America. However until recently the loses of fish was contained to the southernparts of Europe. Because of the constant onslaught of acid rain lakes and riversbegan to lose their ability to counter act their affects. Much of the alkalineelements; such as calcium and limestone; in the soil had been washed away. It isthese lakes that we must be worried about for they will soon become extinct.

A fact that may please fishermen is that in lakes/rivers they tend to catcholder and larger fish. This may please them in the short run however they willsoon have to change lakes for the fish supply will die quickly in these lakes. The problem is that acid causes difficulties the fish’s reproductive system. Often fish born in acid lakes do not survive for they are born with birthdefects such as twisted and deformed spinal columns. This is a sign that theyare unable to extract enough calcium from the water to fully develop
