UV-sensitive

UV-sensitive describes a material, organism, or object that is readily affected or changed by exposure to ultraviolet (UV) radiation. This sensitivity can manifest in various ways, including discoloration, degradation, alteration of chemical structure, increased production of certain compounds (e.g., melanin), or even lethal effects on biological systems. The degree of sensitivity varies depending on the wavelength of UV light, the intensity and duration of exposure, and the specific properties of the subject. Understanding UV sensitivity is crucial in fields like material science, dermatology, and environmental science for predicting and mitigating the potential impacts of UV exposure.

UV-sensitive meaning with examples

• The laboratory’s specialized paper is UV-sensitive, changing color rapidly when exposed to sunlight, revealing any tampering. Scientists carefully monitor the color changes to ensure results remain accurate. This makes the paper invaluable for verifying experiments, providing a clear visual indicator of exposure and protecting against errors in lab procedures.
• Certain plastics used in outdoor furniture are UV-sensitive, leading to fading and brittleness over time. Manufacturers often incorporate UV stabilizers into the plastic to reduce its degradation. This prolongs the lifespan of the furniture and maintains its aesthetic appeal despite constant exposure to sunlight.
• Individuals with fair skin and light eyes are often described as being highly UV-sensitive. This means they are more susceptible to sunburn and skin cancer. Protecting the skin with sunscreen, protective clothing, and limiting sun exposure is crucial to minimize health risks.
• Many phytoplankton species are UV-sensitive, their populations declining in areas with increased UV radiation. This decline can negatively impact the marine ecosystem. Scientists are studying these effects to understand the impacts of ozone depletion and climate change on oceanic life.
