Sunscreen Efficacy By Chemical Composition And Its Effect On Aquatic Life, Taylor Yates

Student Writing

Sunscreen provides protection against skin cancer by reducing UV exposure to the skin. Active ingredients come in two basic forms, chemical and mineral; ongoing research indicates that some active ingredients in sunscreen are harmful to marine life. This study is an analysis of chemical and mineral SPF 30 sunscreens to determine which provides the highest efficacy for skin protection while also providing the lowest toxicity to aquatic organisms. Sunscreen efficacy was tested by exposing photoreactive chemical paper applied with chemical and mineral sunscreens to the sun. Results of the photo effect paper trial showed a wide variation in the efficacy …

The Controversy Of Sunscreen Ingredients: Examining The Relationship Between Oxybenzone And Butylparaben On Stylophorum Pistillata, Brian K. Lee, Natalia Corvalan, Jae Z. Saraum

Exigence

Abstract

The basis of this proposal is to understand the relationship between select UV filters and coral bleaching and provide a framework for additional research. Coral reefs are home to a diversity of marine life and are keystones to major coastal economies around the world. Oxybenzone and butylparaben are major ingredients found in sunscreen that induces coral bleaching to major coral reefs. To alleviate the negative effects, this proposal will attempt to better understand how oxybenzone and butylparaben facilitates coral bleaching and develop an effective and environmentally fair sunscreen. The research proposed will be funded by donors to cover research, …

The Effect Of Changes In Ph On The Production And Respiration Rates Of Native Tape Grass, Vallisneria Americana, Adam Parker

Student Writing

In the past century, the world has seen an increase in the amount of carbon dioxide (CO2) in the atmosphere. The rise in CO2 can put stress on aquatic ecosystems due to ocean acidification, an overall decrease in the pH of the ocean’s waters. Freshwater ecosystems, already stressed by pollution and recent increases in the number of invasive species are also showing signs of acidification due to the increase in CO2. The effect of the rise in acidity is known to be harmful to calcifying organisms, but the effect on freshwater submerged aquatic vegetation (SAV) is not well studied. The …
