CHEMISTRY AND THE ENVIRONMENT

 

CHEMISTRY & THE ENVIRONMENT LECTURE

CHEMISTRY & THE ENVIRONMENT

Essential Question:  What are some of the contributions of chemistry to solving environmental contamination problems ?

Learning Objective:  Chemistry helps the environment by searching for new methods of developing new techniques and materials, removing and decontaminating harmful products. 

SWBAT:

  • Investigate the effect of harmful  environmental products such as lead and mercury poisoning 
  • Learn of ways in which chemists  search for alternatives to replace harmful chemicals
  • Discover the tools chemists use to analyze environmental pollutants

          The periodic table is made up of 118 elements. Some of those elements are extremely  harmful to the environment and life forms. Unfortunately, we are exposed to some of these dangerous elements. Most of us are unaware of the these exposures. 

        The work of environmentalists, politicians, scientists and world-wide volunteers in association with the media is making  the public aware of some of the most important environmental issues we are facing and urging people to take action. 

Mercury is Deadly and Omnipresent 

Mercury metal can be absorbed through your skin, but organic mercury is a much more common threat.

 

          There's a good reason you don't often find mercury (Links to an external site.) in thermometers anymore. While Mercury is located right next to gold on the periodic table (Links to an external site.), you can eat and wear gold, you'd do best to avoid mercury.

          Mercury is a toxic metal that's dense enough that it can be absorbed into your body directly through your unbroken skin. The liquid element has a high vapor pressure, so even if you don't touch it, you absorb it via inhalation.

        Your biggest risk from this element isn't from the pure metal—which you can readily recognize on sight—but from organic mercury that works its way up the food chain. Seafood is the best-known source of mercury exposure, but the element is also released into the air from industries, such as paper mills.

         What happens when you meet up with mercury? The element damages multiple organ systems, but the neurological effects are the worst. It affects memory, muscle strength, and coordination. Any exposure is too much, plus a large dose can kill you.

Lead is the Poison We Live With

Lead is used in or contaminates so many products, it's impossible to completely avoid exposure.

 

          Lead is (Links to an external site.) a metal that preferentially replaces other metals in your body, such as the iron, calcium, and zinc you need to function. In high doses, lead exposure can kill you, but if you're alive and kicking, you're living with at least some of it in your body.

          There's no real "safe" level of exposure (Links to an external site.) to the element, which is found in weights, solder, jewelry, plumbing, paint, and as a contaminant in many other products. The element causes nervous system damage in babies and children, resulting in developmental delays, organ damage, and reduced intelligence. Lead doesn't do adults any favors either, affecting blood pressure, cognitive ability, and fertility.

YOUR SCORE: 


David Attenborough is an English natural historian that has dedicated his life to inform and educate people about our beautiful  planet and the risks we are facing all losing it due to human intervention which include our overuse of chemicals, farming, fishing and overpopulation. 

David is 94 years old and in his lifetime, he has "seen it all." 

He is exposing the past, the present and the future in his documentary. He also presents a solution to our problem. All we need to do is change our ways.
