54 Personal Reflections

Adrianna–

Throughout the semester, working on my toxic metal project has been a really insightful experience that deepened my understanding of how toxic metals can directly impact human health. Before this project, I had a general idea of how metals like lead or mercury were harmful, but I hadn’t fully grasped the extent of their long term health impacts, especially on vulnerable populations like children.

Deeply researching these metals like cadmium, arsenic, lead, mercury, and thallium showed me how closely our health is tied to our environment. I was shocked to learn how these toxins are often found in places that I’d typically consider safe, such as drinking water, household products/dust, and even children’s toys. Learning about the neurological effects of lead or the way cadmium can disrupt the kidneys functioning made the problem of toxic metals in our environment more real and urgent to me. I’ve also found it really informative to learn how toxic metal exposure has impacted populations in different countries, such as Japan through Minamata Disease and Itai-itai Disease. These cases showed me the unfortunate, long term consequences of unchecked industrial contamination and the importance of global environmental health awareness. (AC)

On a personal level, I’ve become more mindful of what I’m exposed to daily. I used to really enjoy tuna and ate it often without thinking twice, but after learning about mercury accumulation in fish, I’ve become a lot more cautious. I’ve started paying closer attention to ingredient lists in foods and even the materials in products I use regularly. Overall, this project has contributed to my understanding of public health by showing how environmental exposures impact health outcomes, how socioeconomic status can increase vulnerability, and why it’s so important to advocate for prevention, education, and policy changes.

Reflecting on my research into toxic metals in consumer products has been quite an eye-opener. I was really surprised to find out about the harmful substances like arsenic, cadmium, lead, and mercury in everyday items, including food, cosmetics, and household products. Realizing that I’ve been unknowingly exposing myself to these toxic metals has made me rethink my daily habits and choices.

Through my research, I learned about the different ways these metals can get into our bodies, whether through eating, skin contact, or breathing them in. It was unsettling to find out that the products I use and consume regularly could be causing long-term health problems. This new knowledge has made me more careful about the items I buy and use.

From now on, I plan to be much more cautious about my diet and the products I put on my skin. It will be much easier to look for healthier options after college, as I will have a more consistent income and can actually focus on my health.

This research has empowered me to make healthier and more informed decisions. By being proactive and mindful of the products I consume and use, I can reduce my exposure to toxic metals and protect my well-being. This reflection serves as a reminder of the importance of continuous learning and staying informed about the potential hazards in our environment. It has truly changed the way I view my daily choices and has motivated me to lead a healthier lifestyle. (DF)

When I first thought of toxic metals, I thought of a radioactive barrel of glowing green goo. After extensive research on them, I now understand they are less obvious. The real danger of toxic metals comes from their silent nature. They slowly and steadily build up, eventually becoming inexorable. I focused primarily on toxic metals in the environment, and while they aren’t the most concerning environmental pollutant, they are certainly extremely concerning. Out of all the toxic metals I researched, mercury and cadmium interested me the most. Mercury always interested me because it’s a metal but also a liquid. Cadmium always seemed futuristic to me, and its use in batteries furthers that idea of a futuristic metal. I never imagined any toxic metal being anywhere outside of a factory or warehouse. Now that I know more about their persistent and bioaccumulative nature, I am even more convinced they should be left alone.

I know there are valuable uses for many toxic metals, but I’m also aware there are other options. Like using nickel-hydride batteries that don’t contain cadmium. But the most important thing I learned from all this research was how necessary regulations are. The single best way to limit the exposure of toxic metals is to regulate it’s release into the environment. This project showed me exactly what happens when regulations are limited, that is, environmental ruin. I have more respect and appreciation for our laws that dictate pollution limits, hold polluters accountable, and save us from exposure.

I will use the knowledge gained from this class and this project to vote for those with strong regulatory backgrounds and try to limit purchasing products made by notorious environmental law violators. (BM)
