“…During the 21-day experiment, the sediment particles on the benthic interface were constantly disturbed and reworked by tubificid worms. Moreover, undulating motion of the posterior end of worms for respiration contributes to turbulent mixing across the SWI [35,45]. Although not a linear change, this increase effect on Dp max is more obvious at large density within the range of natural density of tubificid worms, which was not consistent with the results of VWF.…”

The bioturbation activity of macroinvertebrates can affect the level of water exchange across the sediment–water interface. The impact of tubificid worm with different densities on the vertical water exchange at the sediment–water interface was investigated based on laboratory flume experiments. Vertical water fluxes, as well as physiochemical parameters, were measured at seven-day intervals, and the maximum penetration depths were obtained by dye injection before and after the tubificid bioturbation experiment, respectively. The bioturbation effects can be summarized in two aspects: (1) when the density was less than (or equal to) 20 individual/10 cm2, the volume of vertical water exchange positively correlated with the tubificid bioturbation. Once the density exceeded (or equaled) 25 individual/10 cm2, the vertical water flux decreased with increasing tubificid bioturbation. After 14 to 21 days, a negative correlation was identified between the bioturbation and the vertical water flux under all biological densities. (2) The maximum depth that the surface water can penetrate the sediment increased with increasing tubificid density. These results revealed that the vertical water was closely related to the biological density. The study has certain reference significance to understanding the spatiotemporal heterogeneity of hyporheic water exchange on a local scale.

“…The pH value of the sediment was 7.6. The sediment was rich in organic matter that the loss by ignition was 7.9% (He et al, 2015). Wet sediment was added to plastic mixing containers and then spiked with analytical reagent grade of Cd(NO 3 ) 2 $4H 2 O, ZnSO 4 $7H 2 O, Pb(NO 3 ) 2 and CuSO 4 $5H 2 O successively.…”

“…The experiments of the bioturbation/bioirrigation effects on the heavy metals releasing from the spiked sediment were conducted the same as previous study (He et al, 2015). The experiments were conducted for 29 d in glass beakers with diameter of 13 cm and height of 19 cm which were lined with high density polyethylene film.…”

Bioturbation/bioirrigation can affect the remobilization of metals from sediments. In this study, experiments were performed to examine the effect of bioturbation/bioirrigation by different organisms on cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) releasing from the spiked sediment. The diffusive gradient in thin films technique (DGT) revealed that at the end of exposure time, the labile heavy metals concentrations in the pore water for all metal and organisms combinations except Cu and chironomid larvae were much lower than that in the control group. However, the concentrations of heavy metals detected by the DGT were virtually indistinguishable among the treatments with tubificid, chironomid larvae and loach. The correlation analysis of heavy metals with iron (Fe) and manganese (Mn) suggested that Cd, Zn and Pb were most likely bound as Fe-Mn oxidation form in the pore water, but Cu was in other forms. After 28 d of exposure, bioturbation/bioirrigation produced a significant release of particulate heavy metals into the overlying water, especially in the treatment with loach. The bioturbation/bioirrigation impact on the Pb remobilization was less than the other three heavy metals. The effects of bioturbaiton/bioirrigation on the heavy metals remobilization in the sediment were complex that with studying the heavy metals remobilization in the sediment and water interface, the biological indicators should be recommended.

“…In recent years literature has included issues concerning the biosorption of thallium through the use of, for example, green algae as biosorbents [20,21], fungal isolates [22], Turbificidae, Chironomid larvae, and Loach [23]. Biosorption is a rapid and reversible process [24].…”

Metals play an important role as trace elements in living organisms. However, many metals cause toxic effects [1]. Thallium belongs to a group of highly toxic elements. In living beings, thallium mimics potassium, which favors its accumulation. The toxicity of thalliumbased compounds is mainly caused by the similarity between thallium (I) ions and potassium ions [2, 3], which results in disorder of potassium-associated metabolic processes due to thallium interference [4]. In particular, it accumulates in the internal organs: the liver, kidneys, and muscles, as well as in bones and hair. In addition, it will deteriorate enzyme activity and cause inactivation of sulfhydryl groups (-SH), leading to disturbances in the operation of mitochondria [5]. Basically, there are three methods of thallium intoxication: (i) inhalation, (ii) ingestion, and (iii) contact with the skin. Ingested thallium can enter the body through contaminated water or food, like vegetables, fruits, or meat. It should be noted that the
