Photodegradation of bisphenol A in simulated lake water containing algae, humic acid and ferric ions

Cellular responses and bioremoval of nonylphenol and octylphenol in the freshwater green microalga Scenedesmus obliquus

“…The NP and OP concentration data were fitted well to the first order model, and several processes might be involved in the dissipation processes, including sorption and biodegradation as well as photolysis. It is expected that photolysis of NP and OP induced by the presence of algae might occur, as demonstrated for the enhancement of BPA photodegradation by Chlorella vulgaris and Anabaena cylindrical (Peng et al, 2006). However, Tables 2-3 clearly showed little variation in NP and OP concentrations in the controls within 5 days.…”

Removal of pharmaceuticals and personal care products from wastewater using algae-based technologies: a review

“…As depicted in Eqs. (1-2), algae are able to facilitate photodegradation by increasing the free radical yield (Collén et al 1995;Liu et al 2004;Peng et al 2006). The photodegradation of Norfloxacin was enhanced with algae concentration and was influenced by temperature and pH of the solution (Zhang et al 2012a).…”

Long-term trends of chemical and modelled photochemical parameters in four Alpine lakes

“…On the south, the lake is open to a plain, while high mountains and several lateral valleys are present on both the eastern and western sides, strongly influencing the thermally driven wind field. Lake Iseo is classified as oligo-monomictic, as only two complete overturns have occurred in the last 20 years (March 2005 and2006;Leoni et al, 2014). The reduction in the frequency of full winter circulation episodes in the lake might be linked both to the increased chemical stability of the water column (Ambrosetti and Barbanti, 2005) and to climate change (Valerio et al, 2015).…”

“…These transient species are reactive and they can be involved in the photochemical transformation of many biorefractory pollutants (industrial chemicals, some pesticides, pharmaceuticals and personal care products) and of naturally occurring DOM (dissolved organic matter; Medeiros et al, 2015;Minella et al, 2015). Therefore, they contribute strongly not only to the photochemical self-depuration potential of surface water bodies (Peng et al, 2006;Fenner et al, 2013;Zeng and Arnold, 2013), but also to the biogeochemical transformation of key nutrients (C, N, P). The • OH radical is formed upon photolysis of nitrate and nitrite (reactions 1, 2).…”
