“…As E1 is estimated to have 85% of the efficiency of E2 in endocrine disruption [44], the concentrations measured in these rivers can be well above those recommended by the European Commission [14] for E2 and are higher than some independent predictions for no-effectexposure level, which are as low as 6 ng/L for E1 [45]. Estrogens affect the physiological responses of some molluscs, resulting in feminisation and reproductive disruption [3,46], as well as the reproductive behaviour of crustaceans [47]. Moreover, the effects of EDCs in the aquatic environment…”

There is a growing interest in the possible environmental health impact posed by endocrine-disrupting chemicals (EDCs). A challenge to the field of endocrine disruption is that these substances are diverse and may not appear to share any structural similarity other than usually being low molecular mass (<1000 Da) compounds. Here we demonstrate the effectiveness of sensor device for the detection of low molecular weight, poorly water soluble, estrogenic compounds E1, E2 and EE2, fabricated by electropolymerization over graphene screen printed electrode (SPE). The PANI/Gr-SPE-devices displayed linear responses to estrogenic substances, in EIS assays, from 0.0975 ng/L to 200 ng/L in water samples, with a detection limit of 0.043 pg/L for E1, 0.19 ng/L for E2 and 0.070 pg/L for EE2 which is lower than other current biosensing techniques. This portable, disposable immunosensor offers a solution for immediate measurement at sample collection sites, due to its excellent sensitivity and selectivity when testing water samples obtained directly from rivers and waste water treatment facilities. The simple screen printing production method will enable the low cost, high volume production required for this type of environmental analysis.

“…For instance, in Gammarus tigrinus significant separation effects only at near lethal ethinylestradiol concentrations (Wisniewska and Szaniawska, 2015). Watts et al (2001) observed no effect of environmentally relevant concentrations of the xenoestrogens ethinylestradiol (EE) and bisphenol A on pair re-forming of G. pulex, so the reported effect of other environmental contaminants is particularly interesting.…”

The prevalence of pharmaceuticals and personal care products (PPCPs) in lotic habitats is increasing, with the main source of these contaminants being effluent from waste water treatment works (WwTW). There is still much uncertainty about the impacts of these PPCPs at environmentally relevant concentrations and their potential effects on aquatic ecology. Behaviour is a sensitive endpoint which can help evaluate possible population levels effects from changes in physiology. This paper evaluates the effects of WwTW effluent on a range of behaviours in the freshwater invertebrate, Gammarus pulex. Effluent taken from the outflow of two WwTW in southern England was used in the study.Behavioural analyses, namely feeding rate, phototaxis, activity, velocity and precopula pairing, were measured in G. pulex following a period of one and three weeks after exposure to a 50% or 100% effluent and a control. Mortality remained very low throughout the 3 week experiment (0-10%, n = 20) and no significant changes in moulting frequency were observed (p > 0.05). No significant effects on feeding or velocity or phototaxis following 3 weeks of effluent exposures were observed (p > 0.05). However, significant reductions were observed in the overall activity over 3 weeks across which appeared to be exacerbated by exposure to effluents. Interestingly, males exposed for 3 weeks to WwTW effluent re-paired with unexposed females significantly faster (4-6x) than control animals. This result was consistent between the effluents taken from the two WwTW. The implications of these behavioural changes are currently unknown but highlight the need for a varied set of tools to study the behavioural changes in wildlife. Capsule:The effects of wastewater effluent on the multiple behaviours in the riverine amphipod, Gammarus pulex. Study surprisingly finds very little effects on activity-based behaviours but does find effects of reproductive behaviours.
