“…Protein and lipid content were altered after fungicide exposure. Although the present study analyzed the whole body contents, which may be influenced by the growth effects, our results agree with previous studies that reported lower lipid and protein content in aquatic invertebrates after exposure to fungicides [10,16,57,58].

“…However, the most sensitive energetic parameter varies among organisms and fungicides. In contrast, Mosleh et al [47] and Fidder et al [58] demonstrated that protein and glycogen content were affected in oligochaetes and gastropods after fungicide exposure.

“…The protein content decreased significantly with increasing Filan concentrations (F (1,20) ¼ 11.23, p ¼ 0.003), whereas the lipid Impacts of common fungicides on Austrochiltonia subtenuis Environ Toxicol Chem 36, 2017 content decreased significantly with increasing Systhane (F (1,20) ¼ 7.13, p ¼ 0.015). Although the present study analyzed the whole body contents, which may be influenced by the growth effects, our results agree with previous studies that reported lower lipid and protein content in aquatic invertebrates after exposure to fungicides [10,16,57,58]. This decrease in lipid and protein content in amphipod after fungicide exposure has been ascribed to the increased energy expenditure to deal with toxic stress [10].…”

Fungicides are used widely in agriculture and have been detected in adjacent rivers and wetlands. However, relatively little is known about the potential effects of fungicides on aquatic organisms. The present study investigated the effects of 2 commonly used fungicides, the boscalid fungicide Filan and the myclobutanil fungicide Systhane 400 WP, on life history traits (survival, growth, and reproduction) and energy reserves (lipid, protein, and glycogen content) of the amphipod Austrochiltonia subtenuis under laboratory conditions, at concentrations detected in aquatic environments. Amphipods were exposed to 3 concentrations of Filan (1 μg active ingredient [a.i.]/L, 10 μg a.i./L, and 40 μg a.i./L) and Systhane (0.3 μg a.i./L, 3 μg a.i./L, and 30 μg a.i./L) over 56 d. Both fungicides had similar effects on the amphipod at the organism level. Reproduction was the most sensitive endpoint, with offspring produced in controls but none produced in any of the fungicide treatments, and total numbers of gravid females in all fungicide treatments were reduced by up to 95%. Female amphipods were more sensitive than males in terms of growth. Systhane had significant effects on survival at all concentrations, whereas significant effects of Filan on survival were observed only at 10 μg a.i./L and 40 μg a.i./L. The effects of fungicides on energy reserves of the female amphipod were different. Filan significantly reduced amphipod protein content, whereas Systhane significantly reduced the lipid content. The present study demonstrates wide-ranging effects of 2 common fungicides on an ecologically important species that has a key role in trophic transfer and nutrient recycling in aquatic environments. These results emphasize the importance of considering the long-term effects of fungicides in the risk assessment of aquatic ecosystems. Environ Toxicol Chem 2017;36:720-726. © 2016 SETAC.

“…Another OECD reproductive toxicity test guideline with the pond snail L. stagnalis is also available from 2010 [25] and this optimized in 2016 using the steroidal TBT [30]. Several studies published data with different endpoints (number of egg mass, eggs, survival and shell size) recommended in OECD guidelines in progestogen exposure of L. stagnalis [23][24][25][26][27][28]116]. Based on endpoint results coming from steroid, progestogen effects in snail reproduction, the pond snail, L. stagnalis, beside a mudsnail, Potamopyrgus antipodarum, has been the first aquatic non-arthropod-tests, which were successfully validated within the Conceptual Framework for Endocrine Disrupters [3].…”

In European limnetic systems, the most relevant endocrine-disrupting chemicals (EDCs) of steroid type are the natural and synthetic hormones, phytosterols, pesticides, biocides and other chemicals produced by the plastic industry. Their presence in aquatic ecosystems represents a potentially adverse environmental and public health impact. Furthermore, this is a warning signal that the current handling of pharmaceuticals needs to be further improved. Nowadays, it has become clear that EDCs have specific disturbing effects on the neuroendocrine system of invertebrate and vertebrate aquatic animals, particularly gastropods. Among a latter, pond snail (Lymnaea stagnalis) has been used as the first aquatic non-arthropod test organism in studying the effect of EDCs because they are sensitive to various anthropogenic steroids, like progestogens. Investigating a variety of reproductive endpoints of Lymnaea, such as fecundity, oocyte production, egg mass production, the quality of egg masses, the shell size in development and after egg-laying, the time window of cell division in the offspring, the metabolite content of single-cell zygotes and egg albumen has concluded that progestogen contaminations in water are detrimental for reproduction and early stage development of Lymnaea. This chapter is an attempt to show whether Lymnaea reproduction, despite many altering reproductive endpoints, is a suitable model for environmental risk assessment or not.
