IntroductionIntroductionThe Bronx River

• Twisty stream

• Floodplains, marshland, ravines, beaver and salt-water marshes.

• During 1820’s to 1830’s

• Late 1800’s

Effects of Water Pollution

• Unbalanced river, disrupt lake ecosystem

• Poisonous food animals (bio-accumulation of toxins)

• Poisonous drinking water

• Acid rain Deforestation

•The data for several tests are not shown for several test we did not conduct those experiments for the year 2003. This is due to our desire to show comparison among the data.

DiscussionDiscussion

• Bronx River is worse from year 2003. No real changes has Bronx River is worse from year 2003. No real changes has occurred in the river. occurred in the river.

• The results indicate that the water of the river remains polluted. The results indicate that the water of the river remains polluted.
