“…The exception was the concentration of tributyltin. The highest concentration of the organotin compound was recorded in the sediments from Wislane and Weglowe Quays (Radke et al 2008, Silva et al 2014. Based on the comparison of the available information, it can be concluded that the results of the toxicological analysis (the present study) reflect the actual condition of the harbor sediments.…”

Combustion processes are considered to be the main source of the dioxin emission in the Baltic region. Pentachlorophenol (PCP) and its derivatives, pentachlorophenyl laurate (PCPL) and sodium pentachlorophenate (NaPCP) are known as precursors of dioxins. The research was conducted to obtain the first data on the concentration of PCDD/Fs and PCP in the bottom sediments of the Port of Gdansk. Toxicity (the Microtox® test) as well as several sediment parameters have been examined.In the surface layer of bottom sediments from the Port of Gdansk, all congeners of PCDD/Fs have been detected using GC-MS/MS. The positive correlation between toxicity and physicochemical properties of the analyzed bottom sediments confirms that these parameters are important in terms of environment contamination.

“…TBT and other organotins have been used in industrial applications for PVC production, marine antifouling paints, agricultural pesticides and fungicides, and numerous consumer products and household items [1,[3][4][5][6][7][8]. Consequently, this widespread use has led to an environmental presence in soil, sediment, water and biota where it has been detected in coastal waters at concentrations of ≥500 ng Sn/l and in harbours and shipping lane sediments up to 16,800 ng Sn/g [1].…”

“…This phenomenon is considered the best example of endocrine disruption in wildlife to date with TBT concentrations as low as 1 ng/l of TBT resulting in observable effects [2,7,8,9]. TBT has also been implicated in causing damage to the aquatic food web by preventing the growth of phytoplankton, vital primary producers, and by bioaccumulation and biomagnification in other marine species [1,6,8,10]. Furthermore, TBT is lipophilic and has been detected in the liver and fat cells of animals of higher tropic levels such as: fish, birds, seals, sharks, porpoises and whales at levels up to 790 ng Sn/g causing lethal mutagenic effects and damage to the central nervous systems [1].…”

Tributyltin (TBT) is a synthetic organotin compound and is recognised as the most toxic chemical ever knowingly introduced into the marine environment. Organotins have a wide range of application with an estimated global production of 50,000 tons per year therefore impacts from TBT can be seen or anticipated in many environments including protected areas like aqua farms and world heritage sites effecting aquaculture and undisturbed ecosystems. Due to the impact of TBT a necessity exists for the treatment of contaminated sediment and soil using nature-based solutions as it is both non-invasive and sustainable. However these remediation techniques must also be economically interesting to increase its acceptance. Thus using the biomass from plant species with the ability to cultivate in dredged sediment for biofuel and biomaterials production should be considered to ensure that renewable energy consumption of 10% is meet by 2020. The objectives of this study is to investigate the potential of Hordeum vulgare and Brassica napus to cultivate in marine sediments despite the salinity and TBT pollution for a 30 day pot trial. Further to inoculate seedling roots with known TBT degrading bacteria to enhance the phytoremediation capacity. Also to establish if bacterial isolates C7 and C22 are plant growth promoting bacteria. Statistical analysis on seedlings biomass was carried out followed by analytical analyses by atomic absorption spectroscopy (AAS) and sediment analysis by gas chromatography mass spectrometry (GC-MS). Results showed a maximum decrease of ≥ 82% and ≥ 80% of TBT in sediment samples respectively with bacteria inoculum C7 (KX881905) and C22 (KX881904), further Hordeum vulgare seedlings were the ideal candidate plant species with a significant production of biomass.

“…These pesticides were chosen as they are extensively used in several Mediterranean crops, like orchards and vineyards, and their application is frequently simultaneous. Porcellionides pruinosus was used as a model organism as this is a synantropic and widely distributed terrestrial isopod, frequently used in soil ecotoxicology experiments (Loureiro et al, 2002;Santos et al, 2010;Morgado et al, 2013;Tourinho et al, 2013;Silva et al, 2014;Ferreira et al, 2015). As a decomposer, it is involved in critical processes, such as the turn-over of soil organic matter, nutrient recycling, and also in promoting the degradation of contaminants (Loureiro et al, 2005).…”

Toxicity interaction between chlorpyrifos, mancozeb and soil moisture to the terrestrial isopod Porcellionides pruinosus

A main source of uncertainty currently associated with environmental risk assessment of chemicals is the poor understanding of the influence of environmental factors on the toxicity of xenobiotics. Aiming to reduce this uncertainty, here we evaluate the joint-effects of two pesticides (chlorpyrifos and mancozeb) on the terrestrial isopod Porcellionides pruinosus under different soil moisture regimes. A full factorial design, including three treatments of each pesticide and an untreated control, were performed under different soil moisture regimes: 25%, 50%, and 75% WHC. Our results showed that soil moisture had no effects on isopods survival, at the levels assessed in this experiment, neither regarding single pesticides nor mixture treatments. Additivity was always the most parsimonious result when both pesticides were present. Oppositely, both feeding activity and biomass change showed a higher sensitivity to soil moisture, with isopods generally showing worse performance when exposed to pesticides and dry or moist conditions. Most of the significant differences between soil moisture regimes were found in single pesticide treatments, yet different responses to mixtures could still be distinguished depending on the soil moisture assessed. This study shows that while soil moisture has the potential to influence the effects of the pesticide mixture itself, such effects might become less important in a context of complex combinations of stressors, as the major contribution comes from its individual interaction with each pesticide. Finally, the implications of our results are discussed in light of the current state of environmental risk assessment procedures and some future perspectives are advanced.
