Caused metal as iron, copper and aluminum corroded.

Caused acidic soil and not suitable for cropping

Caused toxic metal such as mercury which release from soil dissolve to the river,lakes it and can cause sediment of heavy metal in river and lakes and passed

through water tap

If the pH of river and lakes goes down below . so many of aquatic organism can

die

Caused plant leave turn to violet and then died.

!xcessive release of acidic gases from motor vehicles and industry caused acid

rain

"cid rain is caused by acidic gas of sulphur oxide and nitrogen oxide to the

atmosphere

"cidic gas reacted with water at the atmosphere or dissolve in rainwater and fall

Agrochemicals that are sprayed on the plants ill be absorbed by soil and finally

The remains of fertili,er are absorbed into the ri%er encouraging fast algal groth

hich ill pre%ent light from reaching the bottom of the ater.

The result is eutrofication ith death of a/uatic plants in the ater of a pond) la"e

The discharging untreated aste into the stream ill cause a disease such as

malaria) s"in disease and cholera

This is because the stream is being used for cleaning) bathing) aste discharging

The symptoms of these diseases is diarrhea) %omiting) stomach cramps)

Phytoplan"ton can0t go through photosynthesis !ecreasing and destruction of phytoplan"ton causes the lac" of food to

The ecosystem and food chain of a habitat ill be disturbed

The spilt oil at the sea bird0s feather and the bird0s cannot fly

&irds feather can0t be function as the conductor) the bird ill be affectedly the

cold) star%ation) droning and poisoning.

Animal and a/uatic life habitat destructed and cause the decreasing of fishes and

thus affected the fisherman income

Oil refinery by using detergent is actually polluted the sea and cause more death
