Bisphenols (BPs) are produced for many applications for used in industry. BPs have been found all part of aquatic environments such as sediment and surface water that is poses a risk to the aquatic ecosystem. Restricting the use of BPA, environmental concentrations of bisphenol S, and bisphenol AF begin to increase. The present study aims to indicate that toxicity BPA and BPA analogues (BPS and BPAF) by algal growth inhibition test for the green algae Chlorella vulgaris, Spirulina sp., Desmodesmus subspicatus. In this way, result of this study present the nominal effective concentrations of BPA analogues and the suitability of the species for use as a biomarker in ecotoxicology tests. IC50 values (growth rate inhibition by 50%, respectively) for three toxicants were determined separately. Results of this study showed the effects of these chemicals on photosynthesis (primer production). The result of algal growth inhibition test showed that BPAF (72h EC50 3.80 mg/L) was found to be more toxic than BPS (3d EC50 6.31 m L-1) for Spirulina sp. BPS (3d EC50 2.43 mg/L) showed the most toxic effect on the growth of C. vulgaris, followed by BPAF with 3d EC50 3.32 mg/L. BPS (3d EC50 0.88 mg/L) and BPAF (3d EC50 6.48 mg/L) were found to be toxic for D. subspicatus, respectively, from highest to lowest toxicity. These results indicate that bisphenol analogues are hazardous to primer production. Therefore, it is necessary to study their combined effects as well as to study how they act individually.

Bisfenol analogları (BP'ler), yüzey suyu, tortu, kanalizasyon ve çamurda sıklıkla tespit edilen bisfenol A'nın (BPA) analoğu olarak endüstride yaygın olarak kullanılmaktadır. Bisfenollerin doğal ortamda bulunması sucul ekosistem için risk oluşturmaktadır. Bu çalışmada BPA, BPS ve BPAF’nin Chlorella vulgaris, Spirulina sp., Desmodesmus subspicatus üzerine akut toksik etkileri incelenmiştir. Spirulina sp. için BPAF (3d EC50 3,80 mg L-1) BPS (3d EC50 6,31 m L-1)’ye göre daha toksik bulunmuştur. Chlorella vulgaris’in büyümesi üzerine en toksik etkiyi BPS (3d EC50 2,43 mg/L) gösterirken onu 3d EC50 3,32 mg/L ile BPAF izlemiştir. Desmodesmus subspicatus için en yüksek toksisiteden en düşük toksisiteye doğru sırasıyla, BPS (3d EC50 1,09 mg/L) ve BPAF (3d EC50 1,89 mg/L) toksik bulunmuştur. BPS ve BPAF karışımının Desmodesmus subspicatus üzerine toksisitesi incelendi. Bu karışımın toksisitesi (3d EC50 1,44 mg L-1) BPS’den az, BPAF’den yüksek bulunmuştur. Bu sonuçlar sucul ekosistemdeki canlılar için risk oluşturduğunu göstermektedir. Bisfenol analoglarının çevresel risk değerlendirilmesini mümkün kılabilmek için BPA’ya alternatif bisfenol analoglarının sucul ortamdaki ayrı ayrı etkilerinin yanı sıra birleşik etkilerinin de daha fazla incelenmesine ihtiyaç vardır.
