“…Comparing their results, it can be concluded that these phytoplankton species are much more sensitive to the action of estrogens than the tested A. variabilis. The results obtained by Liu et al (2010) , respectively. This confirms that the occurrence of synthetic EE2 in the aquatic environment has a more profound effect on the growth of algae than natural estrogens.…”

Many contaminants which are toxic and adversely affect living organisms enter surface waters. Among them, there are endocrine compounds such as steroid hormones, which can disrupt the endocrine system causing an adverse effect on the physiology of aquatic organisms. In the literature, there is not enough information about the influence of steroid hormones on phytoplankton growth. Therefore, the aim of this research was to study the effect of estrogens (estrone, 17ß-estadiol, 17-α-ethinylestradiol, and estriol), progestagens (progesterone, 5-pregnen-3b-ol-20-one, and levonorgestrel), and androgens (testosterone) on the growth of the cyanobacterium Anabaena variabilis. To our best knowledge, the chronic toxicological effects of hormones on cyanobacteria are explored for the first time. ), while estrone, estriol, and levonorgestrel showed no significant effect on the growth of this cyanobacterium. Hormone mixtures have been found to be more toxic than single substances and exposure to them leads to the potentiation of toxicity. The EC 50 after 14 days of the test duration for the mixed steroid hormones were 45.14, 37.00, and 89.46 mg L −1. This research provides a basic understanding of hormone toxicity to aquatic organism, such as cyanobacteria, and asserts a more comprehensive view on ecological risk evaluation.

“…Correa-Reyes et al (2007) reported that the microalga Isochrysis galbana was able to bioconcentrate NP 6940 times, which was then transferred to the organisms feeding on the algae. Liu et al (2010) also reported the 96-h BCF value for NP to be 2077 when the marine diatom Navicula incerta was exposed to 0.001 mg/L of the target compound. The present and previous studies all showed that the two alkylphenols NP and OP could enter aquatic food chains through algal bioaccumulation and might subsequently pose potential risks to organisms at higher trophic levels via biomagnification along food chains.…”

“…Based on the measured concentrations, the removal efficiency (R), bioconcentration factor (BCF), bioaccumulation percentage (BAP) and biodegradation percentage (BDP) of NP and OP by the algal biomass were calculated as previously described (Li et al, 2009;Liu et al, 2010) with minor modifications according to the following Eqs. (9)- (12).…”

Algae are sensitive to a wide range of pollutants, and are effective bioindicators in ecotoxicity assessments. Here, we evaluated the sub-lethal sensitivity of the marine dinoflagellate Cochlodinium polykrikoides upon exposure to copper (Cu), lead (Pb), bisphenol A (BPA), and Aroclor 1016 (polychlorinated biphenyl, PCB). Toxic effects were assessed by observations of the reduction in cell counts and chlorophyll a levels after exposure to each toxicant. C. polykrikoides displayed dose-dependent, sigmoidal responses when exposed to the tested chemicals. EC 50 -72 h values for Cu, Pb, BPA, and PCB were 12.74, 46.70, 68.15, and 1.07 mg L -1 , respectively. PCB, which is an endocrine-disrupting chemical, was the most sensitive, proving its toxic effect on the dinoflagellate. This study provides baseline data on the toxic effects of commonly used heavy metals and endocrine-disrupting chemicals to a marine dinoflagellate.
