Variation of Hazardous and Noxious Substances (HNS) Spectra at Different Wind Condition

Hazardous and noxious substances (HNS) are being increasingly used in various industrial fields, and the transportation of these substances using ships is also continuously increasing. Unlike traditional marine accidents, HNS accidents have high-risk characteristics that can cause fatal and complex physical and environmental damage, such as flammability, explosiveness, toxicity, and corrosiveness [1] – [6] . Therefore, there is a need to develop systematic management technology that takes these HNS accident characteristics into consideration. In the event of an actual accident, the most important factor in the response is to accurately and quickly detect HNS spills to establish an optimal and effective response strategy
