In 1952‚ a toxic smog covered London. This fog continued to blanket the city for four days. Although this is a short period of time‚ the smog had a fatal aftermath. This still continues today and affects the people who were exposed to the toxic fumes. There were many things that contributed to the way the smog started‚ ended‚ and how it became toxic. One main reason why the smog started and lasted so long was because of the weather. There was a high-pressure air mass stalled over the Thames

Southern the needed capital to invest in other projects in the future. In my analysis‚ I looked at the possibility of purchasing and installing scrubbers as pollution control equipment‚ which would create a 90% reduction in your generated sulfur dioxide emissions. Initially‚ this appears to be an excellent strategy; however‚ there exists many constraints. The first constraint is the cost. The scrubbers would cost over $719 million over a three year span. And even though you could depreciate the

Aerobic Respiration in Beans We will evaluate respiration in beans by comparing carbon dioxide production between germinated and nongerminated beans. As shown in the balanced equation for cellular respiration‚ one of the byproducts is CO2 (carbon dioxide): C6H12O6 + 6 H2O + 6 O2 → energy + 6 CO2 + 12 H2O We will use a carbon dioxide indicator ( bromothymol blue) to show oxygen is being consumed and carbon dioxide is being released by the beans. Bromothymol blue is an indicator that turns yellow in

Modernization is linked to other words like urbanization and industrialization. I will talk about industrialization. Industrialization is the conversion of agricultural into a base of manufacturing‚ buildings‚ and villages.

Many people feel that it is the most serious pollution problem that we now face. Scientists say that plant and animal life in thousands of lakes in the United States and Canada has already been destroyed by acid rain. Acid rain forms in the upper atmosphere. There‚ sulfur dioxide and nitrogen oxides mix with water vapor. They mix with water vapor to form sulfuric acid and nitric acid. When the vapor condenses and rain falls‚ the acids fall with it. Every time acid rain falls in a lake‚ the level of acid in the lake rises
