INTRODUCTION

In this project we are going to be testing the reaction of plants to dangerous fumes. You will see the changes that the plant experiments, just by being near these kinds of dangerous fumes. The toxic fume that we will use in the plants is going to be gasoline. This experiment will help us understand how dangerous and strong these fumes are, also, the different results that plants will have responding to different variables. The project takes about 16 days to be complete and get a successful conclusion out of it, because the reactions take time.

QUESTION!

Will plants react to the dangerous fumes? If they do, which reaction will it be? Will they grow? Will the die? What is it going to happen?

RESEARCH

Gasoline is obtained from petroleum in oil refineries, and used as fuel in combustion engines. It is made of over 250 types of hydrocarbons. Aromatic hydrocarbons like toluene and benzene are used to increase the octane rating of gasoline. Other additives are also added to improve engine performance and reduce the emission of harmful gasses formed as byproducts of the combustion process. Some hydrocarbons found in gasoline like benzene are carcinogenic. These hydrocarbons escape into the air around us while we are refilling petrol at a gas station. They also leak from our petrol tanks and the engine exhaust. About 30% to 50% of the hydrocarbons emitted into our atmosphere are released from vehicles. The...
