“…At the same time, point-source pollution from wastewater, waste management, industry and contaminated land has also potentially increased. As a result, pesticides, pharmaceuticals (Leston et al, 2011;Santos et al, 2010), endocrine disruptors (Baptista et al, 2013;Nunes et al, 2011;Ribeiro et al, 2009), metals (Couto et al, 2013), organic material, salt, ammonia and other urban contaminants might have increased in the system, though treatment plants can be successful in removing some of them (EPA, 2010). Such alterations in the type and pattern of LULC driving forces could have implications not only on future management policies, but also on monitoring plans and on the selection of biological indicators.…”

“…Though several pharmacological substances are already within the scope of researchers, new monitoring programs and biological indicators are needed to assess the wide variety of substances used in the food production industry. Leston et al (2011Leston et al ( , 2013, for instance, advocate that Ulva lactuca should be included as an indicator for nitrofuran and chloramphenicol, two illegal antibiotics still in use in Europe.…”

• LULC and LULC changes are important drivers of water condition.• We identified strong signals of systematic transitions.• Consistency and magnitude of systematic transitions reveal processes of LULC change.• Processes of LULC change reveal important drivers of water condition.• Relevant drivers reveal potential pressures linked to the process of transition. Land use and land cover (LULC) are driving forces that potentially exert pressures on water bodies, which are most commonly quantified by simply obtained aggregated data. However, this is insufficient to detect the drivers that arise from the landscape change itself. To achieve this objective one must distinguish between random and systematic transitions and identify the transitions that show strong signals of change, since these will make it possible to identify the transitions that have evolved due to population growth, industrial expansion and/or changes in land management policies. Our goal is to describe a method to characterize driving forces both from LULC and dominant LULC changes, recognizing that the presence of certain LULC classes as well as the processes of transition to other uses are both sources of stress with potential effects on the condition of water bodies. This paper first quantifies the driving forces from LULC and also from processes of LULC change for three nested regions within the Mondego river basin in 1990, 2000 and 2006. It then discusses the implications for the environmental water body condition and management policies. The fingerprint left on the landscape by some of the dominant changes found, such as urbanization and industrial expansion, is, as expected, low due to their proportion in the geographic regions under study, yet their magnitude of change and consistency reveal strong signals of change regarding the pressures acting in the system. Assessing dominant LULC changes is vital for a comprehensive study of driving forces with potential impacts on water condition.

“…Both solutions intend to simulate discharges from aquaculture tanks after the administration of bath treatments with concentrations representing hypothetical dosages for prophylaxis (25 lg mL À1 ) and therapy (50 lg mL À1 ). In order to facilitate the comparison, these concentrations are based on previous experimental designs with furaltadone and chloramphenicol where the same values were tested (for further details see Leston et al, 2011Leston et al, , 2013 and were based on information given by veterinarians.…”

“…When considering a particular group of organisms for both functions attention to their characteristics is very important and should include wide geographic distribution, sedentarity and unequivocal identification (Rainbow and Phillips, 1993;Melville and Pulkownik, 2007). Usually, animal species are selected but primary producers are also being researched for these roles, including macroalgae (Coogan et al, 2007;Melville and Pulkownik, 2007;Akcali and Kucuksezgin, 2011;Costa et al, 2011;Leston et al, 2011). Macroalgae contribute to aquatic ecosystems with high biomass production and also represent an important link in the trophic webs, which can lead to the biomagnification of contaminants.…”

“…The ecological consequences of the presence of STZ in the environment and the possible effects induced in non-target organisms which may include changes in growth rate, reproduction and even lethal toxicity, require further research (Halling-Sorensen et al, 1998;Brain et al, 2004Brain et al, , 2008Kümmerer, 2009;Leston et al, 2011;Ji et al, 2012). To enhance the knowledge on these effects the present study describes experimental data on the exposure of the green macroalgae U. lactuca L. to STZ focusing on the following points: (i) to investigate the stability of STZ in natural seawater, (ii) to assess the influence of STZ on U. lactuca's growth at two concentrations simulating prophylactic and therapeutic dosages (iii) to investigate the possibility of bioaccumulation and biomagnification of the contaminant through the trophic web and (iv) to evaluate the potential use of U. lactuca as a bioindicator and biomonitor for the presence of STZ.…”

h i g h l i g h t sSulfathiazole shows high stability in seawater with 18% degradation over 5 d. Ulva lactuca reduced the concentrations of STZ in the water by efficiently taking up the drug. U. lactuca kept the internal values constant most likely through a detoxification mechanism. Sulfathiazole slightly inhibited the growth of U. lactuca after 96 h of exposure. Macroalgae should be considered as potential bioindicator species in risk assessment of STZ. Sulfonamides (SA) are a class of antibiotics routinely found in environmental matrices and therefore their role as contaminants should be investigated in non-target organisms. With this purpose the present experimental work has evaluated the exposure of the chlorophycean Ulva lactuca L. to sulfathiazole (STZ), a SA drug commonly used in aquaculture, at two concentrations representing prophylactic (25 lg mL À1 ) and therapeutic (50 lg mL À1 ) administrations. Results showed that STZ exhibits high stability in seawater with only 18% degradation over the 5 d assay at both dosages tested. Also, macroalgae demonstrated an efficient uptake capacity with constant internal concentrations after 24 h regardless of the external solutions and thus should be considered as a bioindicator species in risk assessment. Both STZ concentrations induced a slight inhibition of the macroalgae growth after 96 h. a r t i c l e i n f o
