In this study, a fuzzy logic approach was used to determine a new limit value for asbestos exposure. Asbestos is a substance subject to strict regulations due to its adverse effects on human health. Different countries apply different limit values. In this study, a fuzzy inference system was used by considering existing measurement data, international limit values, and risk factors. A total of 289 asbestos measurement results were analyzed and limit values in different countries were compared. The fuzzy inference system was designed using three input variables (current measurements, international limits, and risk factor) and one output variable (new limit value). The system proposed differentiated limit values according to hazard classes for a scenario based on real data statistics. The overall average limit value calculated by the model was 0.013 fiber/cm³. This value is lower than the current EU and US standard of 0.1 fiber/cm³, but higher than the lowest limit value of 0.01 fiber/cm³ applied in some developed countries. The proposed new limit value offers a balanced approach when existing measurement results, international standards, and risk factors are taken into consideration.

Asbest maruziyeti için bulanik mantik yaklaşimi ile yeni bir limit değeri belirleme

Öz

Bu çalışmada, asbest maruziyeti için yeni bir limit değeri belirlemek amacıyla bulanık mantık yaklaşımı kullanılmıştır. Asbest, insan sağlığına olumsuz etkileri nedeniyle sıkı düzenlemelere tabi tutulan bir maddedir. Farklı ülkeler farklı limit değerleri uygulamaktadır. Bu çalışmada, mevcut ölçüm verileri, uluslararası limit değerleri ve risk faktörleri dikkate alınarak bulanık çıkarım sistemi kullanılmıştır. Toplam 289 asbest ölçüm sonucu analiz edilmiş ve farklı ülkelerdeki limit değerleri karşılaştırılmıştır. Bulanık çıkarım sistemi, üç giriş değişkeni (mevcut ölçümler, uluslararası limitler ve risk faktörü) ve bir çıkış değişkeni (yeni limit değeri) kullanılarak tasarlanmıştır. Sistem, gerçek veri istatistiklerine dayalı bir senaryo için, tehlike sınıflarına göre farklılaştırılmış limit değerler önermiştir. Model tarafından hesaplanan genel ortalama limit değer 0.013 lif/ cm³ olmuştur. Bu değer, mevcut AB ve ABD standardı olan 0.1 lif/cm³'ten daha düşük, ancak bazı gelişmiş ülkelerde uygulanan en düşük limit değeri olan 0.01 lif/cm³'ten daha yüksektir. Önerilen yeni limit değeri, mevcut ölçüm sonuçları, uluslararası standartlar ve risk faktörleri dikkate alındığında dengeli bir yaklaşım sunmaktadır.
