Forever Chemicals 

By: Sneha Gummadi

Forever chemicals are chemicals that have long half-lives, meaning that take many years or decades to break down in the natural environment. These chemicals are synthetic, meaning that they are made in factories and laboratories by humans. The moment they are introduced to environments, they do not leave quickly and cause harm in the process to animals, including humans. They contaminate the environment and are taken up by a large variety of organisms. The two most discussed forever chemicals are PFOA (perfluorooctanoic acid/C8) and PFOS (Perfluorooctanesulfonic acid).

These two specific forever chemicals were introduced to the environment during the world wars as by products of weapons. Chemical companies found that these chemicals were perfect for certain kitchen products: nonstick pans. These nonstick pans were made with teflon and the waste from creating teflon were PFOAs and PFOS. DuPont was the main producers of teflon and was dominating the market with this product. They made billions of dollars off of nonstick pans. DuPont would dump these chemicals in water or fill barrels and bury them underground. The chemicals were then exposed to life.

People that got there water from these bodies of water would be drinking contaminated water unknowingly. It leeched into streams that farm animals would drink from. Cows would die with organs that were colored unnaturally. People were getting cancers, fetus development was severely affected, and several other painful diseases. DuPont knew this while they were dumping these chemicals; they had conducted their studies add come to the conclusion that PFOAs and PFOs were extremely dangerous. This was well before they were exposed lawyer Rob Bilott (I have linked the article to the whole story below. It is definitely worth reading for more information).

The EPA says that is still does not know all the possible diseases that these forever chemicals can cause. But there is enough evidence that we should not be ingesting these chemicals. So far the EPA has establish a level of 70 parts per trillion for PFOA and PFOS, but this standard is not regulated well across our country. While people are fighting to get rid of some forever chemicals, companies are coming out with newer synthetic chemicals at a rate faster than we can understand them. The best way we can protect ourselves from further exposure of is to only drink was that has been through activated carbon or high pressure membrane, such as referees osmosis. Boiling water will not get the forever chemicals out. Our public water system now has the facilities to remove forever chemicals. Also we can protect ourselves by buying meat that is well regulated areas. While it might seem that we are still well protected from these chemicals today, we are not. Many court cases continue against forever chemicals even though many studies are coming out showing the negative impacts of forever chemicals. The only way we can show support for these cases and our health is to show companies and our government that we will not buy products that will harm us and the environment. 

Questions:
1. Have you ever heard of forever chemicals or their impact before?
2. How do you think the production of forever chemicals can be tackled by the government?
3. How big of problem do you see this as?

The Great Pacific Garbage Patch: Lyba Farrukh


Everyone knows that pollution is an issue, however very few people know and address how extreme it actually is. A beach is commonplace for people to go to for a vacation and just relax, but what if one day you looked out into the water and all you could see is garbage. Right now between Hawaii and California is the largest accumulation of ocean plastic in the world known as the great Pacific garbage patch. There are millions of tons of plastics entering the ocean and into the gyre. They do not leave the area until they break down into microplastics which are very hard to remove and can be a severe threat to marine life.

Plastic pollution in the ocean not only affects marine life but humans too. Animals often confuse the plastic for food which threatens their behavior, health, etc. A study showed that sea turtles who lived around the patch can have up to 74% of their diets containing plastic. Plastics also contain chemicals that enter the body of the animals consuming it, so when humans eat these same animals for food the chemicals can transfer into their system as well.




The great pacific garbage patch is more than three times the size of Spain and twice the size of Texas. Whenever garbage gets thrown on the ground it most likely will get caught up in a river and end up in the ocean. The amount of plastic in the ocean is increasing and as of right now there are about 80,000 tons of it in the garbage patch. There has also been a measure saying that the amount of microplastics entering the patch is greater than the output.

Even though this issue is becoming very severe, there are many good causes trying to clean up the ocean. One is the Ocean Cleanup project which uses an ocean cleanup device invented by Dutch scientists. It is a 2,000 feet long free-floating broom that is capturing debris from the garbage patch. The plastic they are collecting so far is being brought to shore and recycled. Even though it seems like there is not much you can do about such a large issue doesn't mean we shouldn't try. There are small things we can do such as picking up trash outside or donating money to the cause. I personally have been to the beach many times and become sad whenever I see such a beautiful part of the world covered in garbage, especially when I know it is preventable. That's why it is important for people to be informed about how bad plastic pollution has become and try to prevent it before it is irreversible.

Questions:
1. What are your thoughts on plastic pollution and how severe this issue has become?

2. What are some small ways people can help prevent this problem from becoming worse?
