Abstract: The aim of the Sustainable Management of Sediments Dredged in Seaports (SEDIGEST) project is to assess the risks of treated port sediments for terrestrial ecosystems when deposited in quarries. We simulated the "ageing" of these sediments up to the "moment" when plants can germinate. Sediments were leached by water percolating through a laboratory column. Sediments 1 and 2, taken from the port of Toulon (France), were dried and aired. Sediment 3, taken from the port of Guilvinec (France), was stabilised with l… Show more

“…Plant species are recommended by the U.S. Environmental Protection Agency (EPA) and the Organization for Economic Cooperation and Development (OECD). Many earlier studies have demonstrated that white mustard (Sinapis alba L.) seeds are especially useful for toxicology tests [10][11][12]. The short germination period and fast growth of S. alba seeds are among the advantages of these tests.…”

IntroductionSpring and thermal ponds are important elements of a landscape, and thermal water is among the best environmental geoindicators [1][2]. Earlier studies have demonstrated that the chemistry of thermal ponds is largely influenced by the specific geological setting [2]. The use of thermal water for geochemical energy and improving health is also important [3]. Many earlier studies have demonstrated that thermal water has effects on the human body, e.g., on skin regeneration and the Pol. J. Environ. Stud. Vol. 26, No. 4 (2017), 1585-1590 AbstractPlant seeds are highly sensitive to environmental stress. The aim of our paper was to assess the effects of high nutrient levels in the water and sediment of thermal ponds and rivers on the ecosystem, based on the seed germination and root elongation of S. alba in the Lëngaricës Valley, Albania. Significant differences were found in the physicochemical parameters of the water and the sediment among samples taken from the river, the thermal ponds, and the control ponds. We found significant differences in the root elongation of S. alba seeds based on the water and the sediment of the river, the thermal ponds, and the control ponds. Significantly longer roots were found in the thermal water and sediment than in the river. Among the physicochemical parameters of the water and the sediment, Cu, K, and Li were stimulants for root elongation. With Cu, Li, Ba, Mg, Ni, carbon-dioxide, and sulphate-ion, a stimulant effect was found on seed germination. Our results indicated that the high mineral level of the water and sediment of these thermal ponds had positive effects on the ecosystem based on seed germination and the root elongation test of S. alba.

Sediment management along engineered river systems includes dredging operations and sediment deposition in the sea (capping) or on land. Thus, determining the ecotoxicological risk gradient associated with river sediments is critical. In this study, we investigated sediment samples along the Rhône River (France) and conducted Environmental Risk Assessment (ERA) tests with the idea to evaluate them in the future for deposit on soil. Based on an on-land deposit scenario, the capacity of the sediment samples from four sites (LDB, BER, GEC, and TRS) to support vegetation was evaluated by characterising the physical and chemical parameters (pH, conductivity, total organic carbon, grain size, C/N, potassium, nitrogen, and selected pollutants, including polychlorinated biphenyls (PCBs) and metal trace elements. All tested sediments were contaminated by metallic elements and PCBs as follows:LDB > GEC > TRS > BER, but only LDB had levels higher than the French regulatory threshold S1. Sediment ecotoxicity was then assessed using acute (plant germination and earthworm avoidance) and chronic (ostracod test and earthworm reproduction) bioassays. Two of the tested plant species, Lolium perenne (ray grass) and Cucurbita pepo (zucchini), were highly sensitive to sediment phytotoxicity. Acute tests also showed significant inhibition of germination and root growth, with avoidance by Eisenia fetida at the least contaminated sites (TRS and BER).Chronic bioassays revealed that LDB and TRS sediment were significantly toxic to E. fetida and Heterocypris incongruens (Ostracoda), and GEC sediment was toxic for the latter organism. In this on-land and spatialised deposit scenario, river sediment from the LDB site (Lake Bourget marina) presented the highest potential toxicity and required the greatest attention. However, low contamination levels can also lead to potential toxicity (as demonstrated for GEC and TRS site), underlining the importance of a multiple test approach for this scenario.

The filling of dry quarries in coastal areas with sediments dredged in seaports represents a potentially interesting method of recycling of these materials. However, this recycling requires the prior carrying out of an Environmental Risk Assessment of the scenario concerned. For this, the question arose as to the type of plants capable of developing on the surface of such a deposit and the method to implement for assessing the possible phytotoxicity of dredged sediments. To answer this question, we chose to work with halophytic plants to be free from the salt-related effect and to assess only the effect related to the toxic compounds present. Based on the objectives set, these works led to the use of common plants of the French coast, with direct seeding, and with pollution-sensitive plants. Three species of angiosperms, Armeria maritima, Anthemis maritima and Plantago coronopus, were finally tested. As a result of this work, Armeria maritima was retained as the most suitable plant for testing the possible phytotoxic effect of dredged marine sediments stored on land. The results obtained with this plant are as follows: germination of 40 % of the seeds in 31 days, produced biomass of 493 mg FW in 6 months and a capacity to bioaccumulate metal pollutants in roots with 350 and 720 mg/kg DW for Zn and Cu, respectively.
