For bioremediation to be effective‚ microorganism must enzymatically attack the pollutants and converts them in to non toxic form. n Bioremediation has its limitation‚ some contaminants such as chlorinated organic compound and aromatic hydrocarbon are resistant to microbial attack .bioremediation techniques are typically more economical than traditional method. FACTORS OF BIOREMEDIATION These factors include the existence of a microbial population capable of degrading

also athletes are especially vulnerable to unhealthy levels of air pollution. There are many kinds of air pollution. The ones I want to talk about are the ozone‚ acid rain‚ carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore‚ ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease‚ loss of pulmonary elasticity‚ and

Living organisms are composed of part water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size

Incomplete combustion resulting in the formation of CO or carbon monoxide a highly poisonous and good oxidizing agent. The formation of CO is favoured at lower temperatures contrary to NOx H-C + ½O2 --> CO + ½H2O (Δh = -110.527kJ*) C. Some hydrocarbons are not burnt due to lack of successive collisions between oxygen and fuel. D. Based on our reading‚ observation and calculation‚ we have the

Chemistry Summary The particle theory: 1. Matter is made of tiny particles 2. Particles of matter are in constant motion 3. Particles of matter are held together by very strong electric forces 4. There are empty spaces between the particles of matter that are very large compared to the particles themselves. 5. Each substance has unique particles that are different from the particles of other substances 6. Temperature affects the speed of the particles. The
