What adverse effect can result from overexposure of human tissue to ultraviolet light?
Ultra violet light is responsible for skin cancer. It can also be a problem for individuals with ultra violet sensitive conditions such as Lupus. One would think that staying inside would keep a person safe from this harmful radiation. This is not completely true. Fluorescent lights put off UV light. While this exposure is much smaller than that of sunlight, it is important to keep it in mind. The current guideline limit in the UK is 30 J m-2 for the eye and skin, which is equivalent to a constant irradiance of 1 mW m-2 effective for 30,000 seconds or 8 hours, a normal working day. At close proximity (2 cm or ¾ inch), the exposure limit would be exceeded in less than 10 minutes by about 20% of the CFLs tested. About half of the CFLs exceeded the exposure limit at this distance after 30 minutes. The good news is that if the distance is increased to about 8" only around 8% of the CFL bulbs exceed this limit. Also, encapsulated bulbs that have a globe of glass around the CFL itself emit less UV radiation than the traditional bulbs.
This CFL limit can be overcome with some planning. CFL developers need to keep the guidelines in mind when developing new CFL models. Also, government regulation would help ensure that the UV from CFLs is limited.

ViviOverexposure to ultraviolet (UV) light can cause sunburn, premature aging of the skin, and an increased risk of skin cancer. UV radiation breaks down collagen and damages DNA in skin cells, leading to these negative effects. UV exposure should be limited and protective measures like sunscreen should be used to minimize these risks.

What adverse effect can result from overexposure of human tissues to uv light?
Overexposure to UV light can lead to sunburn, skin aging, and an increased risk of skin cancer. Additionally, it can damage the DNA in skin cells, leading to mutations that may contribute to the development of skin cancer.
What effect would a hole in the onzone layer have on us?
A hole in the ozone layer would result in increased exposure to harmful ultraviolet (UV) radiation from the sun, leading to higher rates of skin cancer, cataracts, and weakened immune systems in humans. It could also have negative impacts on ecosystems, affecting plant growth and marine life.
Do chlorofluorocarbons have a negative effect on the ozone layer?
Yes, chlorofluorocarbons (CFCs) have a negative effect on the ozone layer. When CFCs are released into the atmosphere, they break down and release chlorine, which can destroy ozone molecules. This depletion of the ozone layer can result in increased levels of ultraviolet (UV) radiation reaching the Earth's surface, leading to harmful effects on human health and the environment.
What is the adverse effect of cutting down of trees every year in a large number?
Cutting down trees at a large scale can lead to deforestation, which can result in loss of biodiversity, disruption of ecosystems, soil erosion, and contribute to climate change by reducing the planet's ability to absorb carbon dioxide.
Does wearing sunglasses often negatively effect eyesight in the long term?
No. Long-term wearing may well reduce chances of developing eye diseases or eye problems. Consequently, failing to protect your eyes against harmful UV rays will result in adverse/egative effects.
