“…Thus, it is very significant to evaluate the combined toxic effects of Zn and PFOS to aquatic organisms. In this study, Limnodrilus hoffmeisteri (L. hoffmeisteri) was chosen as the test organism [31,32]. The acute toxicity test was performed at five pH values (5.0-9.0) to assess the effects of the two chemicals on L. hoffmeisteri by selecting mortality rate as the toxicological end point [33].…”

“…These changes may be caused by the combination effect of T. tubifex , carp and microorganisms. It has been proven that, the existence of T. tubifex can accelerate the dissipation of isocarbophos and hexachlorocyclohexanes (HCHs) in sediments 22, 23 . The higher DDD concentrations in sediment may be due to the biotransformation of carp, which conceivably produces feces containing more DDD.…”

Microcosms containing DDT spiked-sediment, Tubifex tubifex and carp (Cyprinus carpio) were constructed to simulate a freshwater system. The accumulation, elimination and toxic effects of DDT (p,p’-DDT, o,p’-DDT), and its metabolites DDD (p,p’-DDD, o,p’-DDD) and DDE (p,p’-DDE, o,p’-DDE) were studied in T. tubifex and carp. Tissue/organ distributions of DDTs were also investigated in carp. The bioaccumulation and elimination of DDT differed in T. tubifex, carp and its tissues/organs. Unimodal or bimodal distributions were observed, and the concentrations of DDT metabolites (DDD and p,p’-DDE) increased over time. The carp organ with the highest concentrations of DDTs (DDT, DDD and DDE) was the gill. The largest mass distribution of DDTs was also in gill, followed by muscle and gastrointestinal tract. Maximum levels of DDTs in whole carp and carp muscle were 161 and 87 ng/g, respectively; therefore, the levels of DDTs observed in carp in this study were insufficient to constitute a health concern if present in fish for human consumption. Significant changes were observed in some biomarkers, including superoxide dismutase, catalase, glutathione-S-transferase, glutathione, and carboxylesterase, in T. tubifex and carp tissues during DDT exposure. Tissue-specific accumulation of DDTs in carp can be a key indicator of exposure to environmentally relevant concentrations.

“…Plastic pollution is one of the primary environmental concerns we are facing today [1]. Microplastics (MPs), typically referred to as pieces smaller than 5 mm in any dimension [2], have been found on beaches, in oceans, seas, rivers, and lakes [2][3][4][5][6][7][8]. One of the biggest concerns regarding MP pollution is that marine and freshwater biota can mistake MP particles for food.…”

Microplastics (MPs) are emerging pollutants, which are considered ubiquitous in aquatic ecosystems. The effects of MPs on aquatic biota are still poorly understood, and consequently, there is a need to understand the impacts that MPs may pose to organisms. In the present study, Tubifex tubifex, a freshwater oligochaete commonly used as a bioindicator of the aquatic environment, was exposed to fluorescent polyethylene microspheres (up to 10 µm in size) to test whether the oxidative stress status was affected. The mortality rate of T. tubifex, as well as the activities of the oxidative stress status biomarker enzymes glutathione reductase and peroxidase, were assessed. In terms of oxidative stress, no significant differences between the exposure organisms and the corresponding controls were detected. Even though the data suggest that polyethylene MPs and the selected concentrations did not pose a critical risk to T. tubifex, the previously reported tolerance of T. tubifex to environmental pollution should be taken into account and thus MPs as aquatic pollutants could still represent a threat to more sensitive oligochetes.
