Toxicity assessment of boron (B) by Lemna minor L. and Lemna gibba L. and their possible use as model plants for ecological risk assessment of aquatic ecosystems with boron pollution

Abstract The present research employs the Ecological Risk Assessment (ERA) method to evaluate the probability of adverse effects in the water supply of Bom Repouso (MG), a city where the agriculture has caused an advanced degree of degradation of its sources. The methodology is based on the integration of different variables, divided into three Lines of Evidence (chemical, physical-chemical and ecotoxicological), and allows for the evaluation of risk assessment between 0.0 and 1.0 in the sampled environment. Five sampling points were evaluated in three periods, with the results varying between the four possible ratings (from low to very high), and it was not possible to identify a pattern of risk evolution between them. Thus, the method used proved to be efficient in assessing the degree of degradation of the environment, however, additional studies are required to improve this type of systemic impact assessment, based on the evaluation of the environmental degradation.

Primary Metabolite

Abstract The worldwide occurrence of pharmaceuticals and personal care products (PPCPs) in aquatic ecosystems is reason for concern, since these emerging micro pollutants, includes a large and diverse group of organic compounds, with continuous input, high environmental persistence and potential threat to biota and human health. The aim of this study was to evaluate, for the first time, the occurrence of twenty-seven PPCPs of various therapeutic classes (including cocaine and its primary metabolite, benzoylecgonine), in the coastal waters of Santa Catarina, southern Brazil. Water samples were taken in November 2020, during the low tide periods, at eight sampling points located along the coast of Santa Catarina, covering its entire geographical extension. Sampling was carried out in triplicate and at different depths of the water column. Nine compounds were detected through liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS): caffeine (12.58-119.80 ng/L), diclofenac (1.398-7.920 ng/L), losartan (0.432-3.200 ng/L), cocaine (0.0248-0.1686 ng/L) and benzoylecgonine (0.0146-1.094 ng/L) were quantified in 100% of the samples; carbamazepine (0.0242-0.2720 ng/L) was quantified in 75% of the samples; acetaminophen (0.212-10.040 ng/L) was quantified in 60% of the samples; and both atenolol (1.13-2.50 ng/L) and orphenadrine (0.073-0.0886 ng/L) were quantified in 25% of the samples. The other PPCPs were below the limit of detection (LOD). The highest occurrence of these compounds was detected in the northern and central coastal region of Santa Catarina, namely in Penha and Palhoça cities. The sources of these compounds may be associated with areas with high population density, awaited by tourism, with consequent production of sanitary sewage and solid waste. The ecological risk assessment of these substances in the aquatic ecosystems showed that 67% and 77% of the compounds respectively presented no ecological risk, acute and chronic, but 44% presented low to moderate risks for acute and chronic effects in the three trophic levels evaluated. The occurrence of these chemical compounds can imply deleterious effects on the environmental health of Santa Catarina coastal zone, and therefore deserve more acute and directed attention.

Sediment Quality Assessment

AbstractStormwater ponds can provide flood protection and efficiently treat stormwater using sedimentation. As the ponds also host aquatic biota and attract wildlife, there is a growing concern that the sediment bound pollutants negatively affect aquatic organisms and the surrounding ecosystem. In this study, we used three methods to assess the accumulation and the potential ecological risk of 13 different heavy metals and metalloids (e.g. trace elements) including both elements that are frequently monitored and some which are rarely monitored in sediment from 5 stormwater ponds located within catchments with predominately industrial activities. Ecological risk for organisms in the older ponds was observed for both commonly (e.g. Cd, Cu, Zn) and seldom (e.g. Ag, Sb) monitored trace elements. The 3 methods ranked the degree of contamination similarly. We show that methods usually used for sediment quality assessment in aquatic ecosystems can also be used for screening the potential risk of other trace elements in stormwater ponds and may consequently be useful in stormwater monitoring and management. Our study also highlights the importance of establishing background conditions when conducting ecological risk assessment of sediment in stormwater ponds.
