Fuzzy Assessment of Heavy Metal Pollution

چکیده مقاله

The present work is aimed to extend the common pollution indices into the fuzzy environment. For this purpose, a method was developed for converting the heavy metal contamination in soil by fuzzy numbers. Then, the most commonly used pollution indices are dened as fuzzy numbers by applying the -cuts approach. To evaluate the degree of heavy metal contamination in a specic level, a degree of belonging was also suggested. The feasibility and eectiveness of the proposed methods were also examined via an applied example.
