Toprak ortamında giderek artan mikroplastik (MP) kirliliği büyük endişe kaynağıdır. Bu çalışmada Konya İli ve yakın çevresinden rastgele seçilmiş olan 20 noktada, 0-20 cm derinlikten alınan toprak örneklerinde mikroplastik miktarı, renkleri ve morfolojileri tespit edilmiştir. Topraklarda mikroplastik kirliliğinin risk seviyesi, kirlilik faktörü (CF) ve kirlilik yük endeksi (PLI) değerleri ile belirlenmiştir. Çalışma sonucunda toprak örneklerinde 80-340 MP/kg arasında MP tespit edilmiştir. Numunelerde %45 fiber (1300 MP); %25 pellet (720 MP) tespit edilirken %51 oranla en fazla şeffaf renkli mikroplastiğe rastlanmıştır. Üç örnekleme noktasında CF değerinin önemli ekolojik risk (3 ≤ CF < 6) oluşturduğu, diğer numuneler için orta seviyede (1 ≤ CF < 3) ekolojik risk olduğu tespit edilmiştir. PLI değerine göre numunelerin tümü için düşük risk (PLI < 10) olduğu tespit edilmiştir. Toprak pH, EC ve organik madde muhtevası ile mikroplastik sayıları arasında anlamlı bir korelasyon tespit edilmezken, fosfor ile orta düzeyli (r=0.56), potasyum ile zayıf düzeyli (r=0.36) korelasyon tespit edilmiştir.

Investigation of microplastic pollution load in agricultural soils of Konya province

Increasing microplastic (MP) pollution in the soil is of great concern.In this study, microplastic amount, colors and morphologies were determined in soil samples taken from 0-20 cm depth at 20 randomly selected points in Konya Province and its vicinity. The risk level of microplastic pollution in soils was determined by pollution factor (CF) and pollution load index (PLI) values. As a result of the study, MP was detected between 80-340 MP/kg in soil samples. While 45% fiber (1300 MP); 25% pellet (720 MP) was detected in the samples, transparent colored microplastic was encountered the most with 51% rate. It was determined that the CF value constituted a significant ecological risk (3 ≤ CF < 6) in three sampling points and that there was a moderate ecological risk (1 ≤ CF < 3) for the other samples. According to the PLI value, it was determined that all samples had a low risk (PLI < 10). While no significant correlation was found between soil pH, EC and organic matter content and microplastic counts, a moderate correlation (r=0.56) was found with phosphorus and a weak correlation (r=0.36) was found with potassium.
