چکیده
|
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 α-cuts approach. to evaluate the degree of heavy metal contamination in a specific level, a degree of belonging was also suggested. the feasibility and effectiveness of the proposed methods were also examined via an applied example.
