Green Chemistry

I do not have any explicitly learned knowledge of green chemistry, but surely have come across these 12 principles. Take for example, designing safer chemicals and designing for energy efficiency.

The hydrogen peroxide replacement of chlorine bleach in paper production leads to polyphenylene sulfone (PPSU) production, which is widely used for indoor airplanes and in underground trains. These non-flammable materials are novel engineering plastic that combines useful environmental, mechanical, and flame-resistant properties. Furthermore, chemical plants can encourage plant growth by waste steam-heating a greenhouse, through which carbon dioxide extrusion is accelerated to feed the growth of plants. 

In both examples, hazardous chemicals have been replaced by more sustainable products. The first discusses that plane and train equipment have evolved to be less flammable, which means that if any equipment combusts, they release less toxic chemicals, help minimize air pollution, and less damaging to passengers’ health. In the second example, industrial waste is utilized for an economic and environmental benefit because what was initially polluting the atmosphere can be transformed into a growth-promoting substance. 

Overall, the 12 principles of green chemistry provides a wonderful guideline for scientists and reminder for the general public. It is incredibly useful for the scientific and layman community to establish and be aware of these principles because it provides a standard for the sake of improving environmental health.

    It is incredible how useful and less harmful hydrogen peroxide really is. I use it often for home remedies, but learning that it is used for indoor airplanes and on underground train is reassuring that it has even more use than I expected.

    The 12 principles of green chemistry is extremely helpful for anyone to learn about possible environmental hazards. With regards to your other example of industrial waste, it is important to acknowledge that we use the safest and environmental friendly to dispose chemical substances.

Pesticides

Using the “What’s on my food” website, I searched the general food items which comprised the previous night’s dinner: chicken breast, rice, green beans, and water. My search began with mild results, but became progressively worse as I went to the next food item. Chicken breast was found to have 7 pesticide residues; 2 presenting with developmental or reproductive toxins. Rice was found to have 15 residues, with 10 suspected hormone disruptors. Green beans had 44 residues; 21 of which were suspected hormone disruptors and 11 were neurotoxins. For water, there were 14 suspected hormone disruptors and 9 developmental or reproductive toxins among the 59 residues found. These findings are nothing to be proud of, but it made me realize how our diet greatly impacts our overall health. Although the general population may be working towards a well-balanced diet, the food items they consume—no matter how “healthy”—are actually causing internal chaos as the pesticide residues wrea...

Tap Water Campaign: #BackToTap

The daily recommendation for water intake is 8-11 glasses each day. It is detrimental to human health to have access to drinkable water because if not, then the body will become dehydrated and thus reducing its regular functions. If I were to develop a campaign to encourage nationwide use of tap water, I would call it #BackToTap. Prior to the rise of bottled water, people survived sufficiently with water from the tap. So, let’s get #BackToTap and use bottles for repeated use. If people go #BackToTap, we reduce the manufactured demand for bottled water, which help to also reduce plastic waste. This will also encourage consumers to fill their reusable bottles with the amount they can drink. This campaign will benefit many aspects of environmental health from waste reduction and water conservation. Join me in the fight for #BackToTap!

Environmental Justice

Environmental justice is defined as the fair treatment and involvement of everyone regardless of race, nationality, color, or income as they pertain to environmental law development, implementation, and enforcement. At the People of Color Environmental Leadership Summit, the 17 principles of environmental justice were created which helped to environmental justice and ways people can attain it. Environmental justice can be connected with the “Black Lives Matter” movement because both emphasize the fair and equal treatment of people, but obviously the movement in question particularly fights for Black rights. Another connection is evidenced by the article in Atlanta Black Star, which demonstrated that Black communities are vulnerable populations due to their race/ethnicity being historically being in the lower income bracket. Playing a role here are the social determinants of health which include: economic stability, education, social and community context, health and healthcare, an...
