“…For example, algae with cell wall, like Chlorococcum sp., could be less vulnerable to chemical substances, thus bearing higher growth rates after prolonged exposure periods, probably due to adaptation and metabolic regulations [ 51 , 68 ]. On the other hand, the presence of hazardous substances at levels almost critical for growth could inhibit or prompt algal growth [ 69 , 70 ], depending on the elimination rates of the tested species [ 71 ]. Moreover, there is evidence that chemical substances could disturb cell wall integrity, thus leading to cell division dysfunction [ 72 , 73 ], before algal adaptation occurs over time, as revealed by PCMB-treated Scenedesmus rubescens low growth rates and cell density.…”

Considering that electronic wastes (e-wastes) have been recently recognized as a potent environmental and human threat, the present study aimed to assess the potential risk of personal computer motherboards (PCMBs) leaching into aquatic media, following a real-life scenario. Specifically, PCMBs were submerged for 30 days in both distilled water (DW) and artificial seawater (ASW). Afterwards, PCMBs leachates were chemically characterized (i.e., total organic carbon, ions, and trace elements) and finally used (a) for culturing freshwater (Chlorococcum sp. and Scenedesmus rubescens) and saltwater (Dunaliella tertiolecta and Tisochrysis lutea) microalgae for 10 days (240 h), (b) as the exposure medium for mussel Mytilus galloprovincialis (96 h exposure), and (c) for performing the Cytokinesis Block Micronucleus (CBMN) assay in human lymphocytes cultures. According to the results, PCMBs could mediate both fresh- and marine algae growth rates over time, thus enhancing the cytotoxic, oxidative, and genotoxic effects in the hemocytes of mussels (in terms of lysosomal membrane impairment, lipid peroxidation, and NO content and micronuclei formation, respectively), as well as human lymphocytes (in terms of MN formation and CBPI values, respectively). The current findings clearly revealed that PCMBs leaching into the aquatic media could pose detrimental effects on both aquatic organisms and human cells.

“…Stimulation effects in 72-h algae growth inhibition tests, as observed in our experiments, have been reported for several freshwater and marine algae in the literature. Harbi et al (2017) reported slight growth stimulation of the marine green algae Dunaliella tertiolecta when exposed to 6.25 and 12.5% (v/v) of a wastewater treatment plant effluent. Libralato et al (2016) reported growth stimulation effects ranging from 2 to 102% on P. tricornutum for 75 out of 93 tested wastewater samples.…”

To estimate mixture effects caused by the high number of chemicals simultaneously present in the environment, methods for routine effect assessment of environmentally realistic contaminant mixtures are needed. We repeatedly exposed the marine diatom Phaeodactylum tricornutum to SpeediskTM passive sampler extracts and observed statistically significant growth stimulation up to 6 and 7% for samples from inside and outside the harbor of Zeebrugge, respectively. These effects were found at summed contaminant concentrations (159–166 ng L–1) that were within a 1.1‐ to 2.4‐fold range of those observed in grab water samples taken during sampler deployment. These stimulatory effects were confirmed in 2 independent tests with extracts stored for <1 or 8 mo that had undergone limited sample handling, whereas no effects were observed for extracts that had been stored for 16 mo that had undergone repeated handling (notably repeated freezing and thawing) before biotest spiking. Targeted analysis by ultra‐high performance liquid chromatography was performed to quantify 88 personal care products (n = 8), pesticides (n = 28), and pharmaceuticals (n = 52). Among these compounds, multivariate statistical analysis put forward the β‐blocker atenolol as explaining most of the observed variation in mixture composition between the growth‐stimulating and no effect–causing extracts. However, when tested individually over the entire concentration range present in the extracts, atenolol did not have any effect on P. tricornutum, suggesting that nontargeted substances in the extracts may have contributed to the observed stimulatory effects. Nevertheless, the present study shows that exposure to contaminant mixtures at environmentally realistic concentrations can lead to small but significant growth stimulation effects on the marine diatom P. tricornutum.
