“…They underlie productivity in aquatic environments and are widely used as biomarkers. Among the different species, pigments and fatty acids are mainly used in the study of pollution [ 3 ]. Primary aquatic production is carried out by phytoplanktons, which absorb pollutants from the surrounding water and incorporate large quantities into their cellular compartments.…”

“…Seawater covers 97% of surface waters and is considered one of the most abundant resources on our planet [ 1 ]. The unsustainable use of marine waters and resources by humans has altered the structure of marine ecosystems, relating to the phenomenon of eutrophication, loss of diversity or the presence of polluting chemicals [ 3 ].…”

An Overview of Analytical Methods to Determine Pharmaceutical Active Compounds in Aquatic Organisms

There is increasing scientific evidence that some pharmaceuticals are present in the marine ecosystems at concentrations that may cause adverse effects on the organisms that inhabit them. At present, there is still very little scientific literature on the (bio)accumulation of these compounds in different species, let alone on the relationship between the presence of these compounds and the adverse effects they produce. However, attempts have been made to optimize and validate analytical methods for the determination of residues of pharmaceuticals in marine biota by studying the stages of sample treatment, sample clean-up and subsequent analysis. The proposed bibliographic review includes a summary of the most commonly techniques, and its analytical features, proposed to determine pharmaceutical compounds in aquatic organisms at different levels of the trophic chain in the last 10 years.

“…Methods of biomonitoring using macrophytes, such as these, are incorporated in the European Water Directive Framework. Macrophytes may also be used as bioindicators and biomarkers to detect pollution by crude oil (Lopes et al, 2014;, metals, water sewage, pesticides, pharmaceutical drugs and other contaminants (Lomartire et al, 2021).…”

Macrophytes are considered key components of aquatic ecosystems and they also provide multiple benefits for humans. In this review, I identified and exemplified 26 types of ecosystem services provided by macrophytes. The most important supporting services provided by these plants are related to nutrient cycling and provisioning of habitat, but macrophytes also participate in water cycling and gases production. The presence of macrophytes and their activity enhance water purification and disease control which are important regulating services. Provisioning services are provided in the form of food at the local and global scale (e.g., rice), fiber, biochemicals, natural medicine and ornamental resources. Cultural services are provided in the form of spiritual and religious artifacts and local knowledge systems of communities which depend on macrophytes for surviving. Other cultural services are associated with educational activities, art inspiration, esthetic values in aquatic gardens and ponds, uses for leisure, recreation and ecotourism. There is evidence that the efficiency of ecosystem functioning, the provision of ecosystem services and ecosystem stability is enhanced by macrophyte diversity. Because macrophyte communities provide important benefits for humans, their conservation and restoration, where necessary, are important for human well-being.

“…Upon stressors' exposure, organisms may undergo differential biological responses at morpho-physiological functions that can occur in a broader range of biological levels (from cells, tissues, organs to ecosystem level) (Sharma et al 2022). Therefore, to achieve a complete and integrative overview of an organism's health, a multi-level biomarker approach, including biochemical, behavioral, genotoxic, physiological, molecular and histopathological markers, has been widely used within ERA (Samanta et al 2018;Lomartire et al 2021).…”

Histological techniques consist of traditional and very important tools for a better understanding of cellular morphology and physiology in ecotoxicological studies. Despite bioassays generally recommending the use of small test organisms, based on some advantages as their low maintenance costs and large replicates’ number, the histological processing of small organisms is not commonly used due to demanding laboratorial handling. The present study proposes an accessible protocol for a histological method in fish larvae with a maximum length of 8 mm, as well as the use of histopathological biomarkers on Senegal sole larvae for ecotoxicological testing. Eight-day old larvae of Solea senegalensis obtained from breeders' natural spawns in cultivation conditions were submitted to histological processing by an adjusted protocol comprising fixation, agarose array pre-embedding, paraffin embedding, slides preparation, and image analysis by light optical microscope coupled to a digital camera. Low-cost and easy-to-use alternatives were applied in the technique execution. The histological steps were detailed and the multiple tissues and cellular structures of the S. senegalensis larvae were described and discussed. This can be considered a valuable background information for ecotoxicological studies where changes in cell morphology and physiology are expected.
