Glowsticks Glowsticks What chemicals are used in this process? What chemicals are used in this process? Most common chemicals used in glow sticks: - phenyl oxalate ester - hydrogen peroxide - fluorescent dye What are some chemical reactions involved in this process? What are some chemical reactions involved in this process? When you bend a glow stick, it causes a glass vial inside to break, releasing the phenyl oxalate into the plastic tube containing hydrogen peroxide and fluorescent dye. When the chemicals mix a chemical reaction occurs called chemiluminescence which is the production of light through a chemical reaction, producing minimal to no heat. What are the by-products of this chemical process? What are the by-products of this chemical process? One of the by products from the chemical reaction that occurs with glow sticks is phenol. Phenol is an acid usually found in coal which is toxic.If you ingest phenol it can cause nausea, vomiting, circulatory collapse, tachypnea, paralysis, convulsions, coma,and death.Death has occurred from ingestion of as little as one gram of phenol. What products are created at the end of this process? What products are created at the end of this process? Light is the product produced at the end of this process through the mixture of hydrogen peroxide, phenyl oxalate and fluorescent dye. Light is the result of chemiluminescence. How is this chemical process affecting the surrounding environment and the local population? How is this chemical process affecting the surrounding environment and the local population? - non biodegradable (plastic shell) - chemicals are very harmful to environment once they're
released/pollute the air - highly flammable - derived from petrochemicals - requires a lot of energy to make (energy intensive) - non recyclable - single use - safety risks for production staff Factory info: Factory info: Zhe Jiang Guangyuan Toys Co., Ltd was established in 1996. This company, located in China, specializes in the creation of glow sticks, glow bracelets, and glow in the dark fishing bobbers (just to name a few). Their products sell in over 30 countries and regions, including Europe, USA, and Japan. These products are safe and non-toxic. Skin or eye contact will cause temporary irritation, but will not cause any permanent effects. Each item comes in a rainbow assortment of colours. The factory is not near any forests or thriving ecosystems. It is in an area where there are many other factories owned by different companies and they produce many different products. The factory is responsible for proper waste disposal management and is required to ensure the safe disposal of any and all chemical waste. After the glow sticks leave the factory, the disposal is then the responsibility of consumer. Most are just thrown away and end up in landfills. They are not biodegradable but the chemicals when released do contribute to air pollution. Effects on the surrounding local populations Effects on the surrounding local populations By Bronwyn, Heidi, Maizee, and Julia By Bronwyn, Heidi, Maizee, and Julia Most poison control centers for animals as well as the general public maintain that the majority of glow products are a low toxicity issue. One poison control expert claims that they are poisonous because it can make people sick and cause some symptoms, however it’s not something that would send someone to an emergency room. There are many urban legends which claim that some chemicals inside of glowsticks contribute to cancer, however this is not true. There is no scientific evidence to prove that they have any contribution to cancerous activity. Can this industrial process be beneficia? Can this industrial process be beneficial? The production and retail are prime opportunities for jobs in different communities. It provides an income for many families with jobs in the factories as well as any retailers of these products. The environmental impact is minimal compared to many other products out there so it does not directly impact communities. The glowsticks provide a fun and entertaining product for parties or special occasions and everyone appreciates this common chemical reaction. It is a prime example of how we use simple sciences in our everyday lives. The End The End
