industrialization has been the significant depletion of the ozone layer. This depletion could have an incredibly devastating impact on the world and more specifically agriculture. In general, " plants are quite sensitive and fragile when confronted with ultraviolet increases " ( Zimmer, 1993, p.28 ). Words such as sensitivity and fragility only add to the urgency of the possible agricultural holocaust. One agricultural scientist remarked, " soybeans, tomatoes, tobacco, potatoes, corn, beans, and

In today’s world, the access to clean water is unspeakably easy. Technology has revolutionized what it means to get clean water that is safe to drink, shower in, and play in. The water that is consumed by humans comes from water treatment plants, making it perfectly safe. Many people don’t think about where their water comes from, or the process it has to go through in order for it to be consumable. However, many countries do not have access to clean drinking water. In other places, people have to

Contaminated Water and UV Light In today’s world, the access to clean water is unspeakably easy. Technology has revolutionized what it means to get clean water that is safe to drink, shower in, and play in.

Many people don’t think about where their water comes from, or the process it has to go through in order for it to be consumable. However, many countries do not have access to clean drinking water

from the damaging effects of ultraviolet radiation. When skin is exposed to ultraviolet radiation, melanocytes increase their production of melanin, which generates darker pigmentation of the skin. Ultraviolet radiation stimulates malignant changes within the melanocytes by mutating DNA, stimulating cutaneous growth factors, decreases immune defenses, and promotes species of melanin that cause DNA impairment and suppress apoptosis. The abnormalities caused by ultraviolet radiation in the melanocytes

sun protector factors and is “ is a relative measure of how long a sunscreen will protect you from ultraviolet (UV) B rays”. UVB rays are also the leading cause of skin reddening and sunbird due to the ultraviolet rays penetrating the outer layer, epidermis, of the skin. Also, this form of sun rays causes the most common, and least dangerous, form of skin cancer. The UV in both stands for ultraviolet referring to the rays from the sun. According to Coola (N.D.), the difference between UVA and UVB

responsibility of deciding which product will best protect. A parent can be overwhelmed by the available choices. This project will clear the fog of misleading labels and get down to the cold hard facts of which brand of sunscreen blocks out the most ultraviolet light. In order to test this one would need to understand three things. First, what is light and where does it come from? Then, learn about the damage that UV light and radiation may cause. Lastly, we shall learn how to protect ourselves from these

that increase the risk of melanoma, these factors include exposure to ultraviolet radiation and genetics. Melanoma is most common in lighter skinned caucasians born after the 1940s (Erdmann et al 2012) as genetically they are not as resistant to Ultraviolet radiation, with certain trends such as sunbathing and the use of a tanning booth, individuals unaware of the risks to melanoma are purposely exposing themselves to Ultraviolet radiation to create a desired tan. Melanoma is the

Ultraviolet radiation may give you sun burns, but it also can be used to disinfect edibles, water, hospitals, etc. (“How Does UV”) You can kill microorganisms in a variety of ways, including the right amounts of humidity, energy, water, air, or light. (Maczulak 229) A germ’s existence is counted in minutes, so it relies on reproduction. Damaging the DNA would kill it, because the bacteria wouldn’t be able to split or reproduce after it absorbs the UV rays. When the UV reaches the DNA, it breaks down

pigment because melanin producing cells, melanocytes, are absent or nonfunctional, leaving patches of white areas throughout the body. Recently, ultraviolet B phototherapy (UVB) has been used to target areas of lesions in order to repigment and stabilize vitiligo. This paper presents a review on vitiligo therapy that focuses on the effects of ultraviolet B light and aims to examine the success rate of this specific therapy. In particular, it will evaluate how UVB exactly induces melanocyte proliferation

The basic component in tanning is ultraviolet light. Ultraviolet light, whether produced by a tanning unit or by the sun, contains two components; UVA and UVB. These are the two types of ultraviolet radiation that are known to negatively effect the skin. UVA has a longer wavelength that causes photoaging and can produce some melanomas. UVB has a shorter wavelength
