Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
Ultraviolet radiation spans wavelengths from about 10 nm to 400 nm and is an important component of sunlight although the ozone layer prevents much of it from reaching the earth's surface. It is seperated in UV-A, UV-B and UV-C light. UV-C and UV-B light have a damaging effect on DNA and can therefore act as a desinfectant (killing microbes) or cause skin cancer and genetic mutation.
