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

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.
