“…Consistent algal growth inhibition was observed in the present study, especially for higher BP-1 and BP-3 concentrations ( Figure 1 ). This agrees with a previous report that BP-1 and BP-3 can cause growth inhibition of green algae in the low mg L −1 range [ 20 , 22 ]. In facts, a much lower effect concentration (72-h EC 50 : 13.9 µg L −1 ) was reported for a marine algal species, Isochrysis galbana [ 40 ].…”

“…From these studies, half maximal effective concentration (EC 50 ) values of BP-3 for green algae were estimated to be 0.25 mg L −1 for Skeletonema pseudocostatum , 0.96 mg L −1 for Desmodesmus subspicatus , 1.85 mg L −1 for Chlamydomonas reinhardtii and 22.4 mg L −1 for Chlorella vulgaris [ 18 , 19 , 20 , 21 ]. The EC 50 (72 h) of BP-1 was reported to be 10.5 mg L −1 for green alga, Raphidocelis subcapitata [ 22 ]. These studies suggested that BP-type UV filters can affect the multiplication of green algae individually.…”

The widespread occurrence of benzophenone-type ultraviolet (UV) filter has raised the public concerns over the ecotoxicological effects of these chemicals. The present study assessed the joint toxicity of two representative benzophenones, benzophenone-1 (BP-1) and benzophenone-3 (BP-3), on the green alga Chlamydomonas reinhardtii using response surface methodologies (RSM). Specific growth rate and photosynthetic pigments were used as endpoints to evaluate the toxic effects. Generally, exposure to the combined BP-1 and BP-3 negatively affected cell growth and pigments production, with higher inhibitions at higher exposure concentrations. The simultaneous reduction in growth rate and pigments contents indicated that BP-1 and BP-3 regulated the growth of the tested alga by affecting the photosynthesis process. Results also showed that second order polynomial regression models fitted well with experimental results for all endpoints. The obtained regression models further indicated that the effects of the combination stemmed significantly from the linear concentration of BP-1 and BP-3. The overall results demonstrated that RSM could be a useful tool in ecotoxicological studies.

“…For instance, EC50 values of selected organic filters (e.g. BP-3, BP-4, EHMC, 4-MBC) in standardized toxicity assays on three aquatic species, Daphnia magna , Raphidocelis subcapitata and Vibrio fischeri , were in the mg/l range for all the species, which suggest minimal risk for these organism in their natural ecosystems [32] . However, like many researchers suggest, toxic effects of chronic, low-dose exposures cannot be ruled out and require further investigations [32] .…”

Neurotoxic effect of active ingredients in sunscreen products, a contemporary review

et al. 2017

View full text Add to dashboard Cite

Sunscreen application is the main strategy used to prevent the maladies inflicted by ultraviolet (UV) radiation. Despite the continuously increasing frequency of sunscreen use worldwide, the prevalence of certain sun exposure-related pathologies, mainly malignant melanoma, is also on the rise. In the past century, a variety of protective agents against UV exposure have been developed. Physical filters scatter and reflect UV rays and chemical filters absorb those rays. Alongside the evidence for increasing levels of these agents in the environment, which leads to indirect exposure of wildlife and humans, recent studies suggest a toxicological nature for some of these agents. Reviews on the role of these agents in developmental and endocrine impairments (both pathology and related mechanisms) are based on both animal and human studies, yet information regarding the potential neurotoxicity of these agents is scant. In this review, data regarding the neurotoxicity of several organic filters: octyl methoxycinnamate, benzophenone-3 and −4, 4-methylbenzylidene camphor, 3-benzylidene camphor and octocrylene, and two allowed inorganic filters: zinc oxide and titanium dioxide, is presented and discussed. Taken together, this review advocates revisiting the current safety and regulation of specific sunscreens and investing in alternative UV protection technologies.

“…Although some pioneer studies have been published, the detection, degradation under different redox conditions (Jurado et al, 2014b;Rodríguez-Escales and Sanchez-Vila, 2016), transport (Martínez-Hernández et al, 2014), and groundwater risk assessment (Molins-Delgado et al, 2016) of PCPs in groundwater has not yet been comprehensively studied and discussed (Hopkins and Blaney, 2016).…”

A steady increase in the consumption of pharmaceuticals and personal-care products worldwide is increasing their occurrence in the biosphere. The current study describes the abundance of 42 selected emerging organic contaminants (EOCs), including human and veterinary antibiotics, UV-filters and analgesics in the groundwater of the urban aquifer of Zaragoza (Spain), which is affected by intensive exploitation of shallow geothermal resources. The presence of groundwater heat pump systems in the aquifer studied offered the opportunity to study the occurrence of EOCs in relation to groundwater temperature and other physicochemical effects derived from this technology. Analysis of the data obtained allowed us to identify statistically significant relationships between the presence of EOCs and temperature, as well as other physicochemical and geochemical properties of groundwater. The results obtained suggest that temperature is a minor factor controlling the degradation of the organic compounds analysed compared to the oxygen input from groundwater heat pump systems which is possibly increasing the aerobic redox conditions, thus preventing the degradation of organic pollutants. Intensive use of shallow geothermal resources therefore seems to contribute in the prevalence of such compounds in the aquifer close to geothermal systems.
