The present invention relates to an apparatus and a method for predicting the dispersion of hazardous and noxious substances and, more specifically, provides an apparatus and a method for predicting the dispersion of hazardous and noxious substances, the method: checking the components of the hazardous and noxious substances having leaked into the ocean, so as to classify the hazardous and noxious substances into a corresponding classification set among twelve classification sets by means of at least one of vapor pressure, the degradation in water, or density; dividing the classification sets, in which the hazardous and noxious substances are classified, into one dispersion model among an air dispersion model, a seawater dispersion model, and an air/seawater dispersion model according to the dispersion characteristics thereof; acquiring, from a weather center server, the state information of a sea area, which is set to be different according to the divided dispersion models; and predicting a danger radius for the dispersion of the hazardous and noxious substances by using the acquired state information of the sea area, and outputting the same.

Apparatus and method for predicting dispersion of hazardous and noxious substances

The present invention relates to an optical analysis device using a multi-light source structure, which allows acquisition of an optimized measurement result by adjusting the number of light sources depending on a concentration of an object to be measured, such as ocean spilled oil, etc., and a method therefor. The optical analysis device using a multi-light source structure may comprise: a multi-light source unit including multiple light source units each having a light source which is selectively illuminated, in order to adjust an amount of light depending on a concentration of an object to be measured; a cuvette unit including a cuvette in which an object to be measured is disposed, wherein the cuvette has a prism shape and has as many faces as the number of the light source units plus one, the light source units faces the faces, respectively, and reactive light generated from the object to be measured is emitted through the remaining one face; a light sensor unit for detecting the reactive light emitted through the cuvette; and a control unit for controlling illumination of the light source units configuring the multi-light source unit.
