“…On the other hand, the interactions between heavy metals and MPs triggered a big splash after the sorption of metals to MPs became a frequently reported problem during sample storage or in experiments involving the metal standards. 153 However, a few review studies have focused on the adsorption of different trace metals (Al, Fe, Mn, Cu, Zn, Pb, Ag, Cd, Co, Sr, Mo, Sb, Sn, and Ni) by MPs. 7,44,87 The adsorption of heavy metals to MPs is dependent on the physicochemical properties and modifications of each metal on MPs ( i.e.…”

“…The majority of previous studies focused on contaminants and microplastic interactions in waters, e.g., storm waters [ 7 ], marine waters [ 3 ] or water sediments [ 8 ], showing that MPs can play a key role as a vector of chemical contaminants in marine ecosystems [ 9 ]. MPs are confirmed to have a high affinity to heavy metals from the aqueous phase [ 10 ], rapidly adsorbing heavy metals from nearby metal sources [ 11 ]. Much less is known about MPs in terrestrial ecosystems; nonetheless, microplastic pollution in soil is considered as an important point source of contaminants in aquatic ecosystems [ 12 ].…”

Microplastics, due to their surface properties, porosity and electrostatic interactions have a high affinity for cations sorption from the aqueous phase. As soil is a complex matrix, interactions between microplastics, soil constituents and heavy metals (HM) may modify the soil microenvironment for heavy metal mobilization/immobilization processes. In order to better understand the problem, three commonly found forms of microplastics in soil (fibers, fragments and microbeads) were mixed with Cu2+- or Pb2+-contaminated soil and incubated at 22 °C for 180 days. In soil samples pH and the content of water and acid exchangeable species of metals were analyzed. The results of this study showed that the presence of microplastics in HM-contaminated soil affected metal speciation, increasing the amount of easily exchangeable and potentially bioavailable forms of Cu2+ or Pb2+ in the tested soil. Soil pH also increased, confirming that microplastic particles affect soil properties relevant to the sorption/desorption process of metal cations. Overall, the smallest microplastic particles (≤1 mm), such as fibers or glitter microbeads, had a greater impact on the change in the sorption and desorption conditions of metals in tested soil than larger particles. The findings of our study show that microplastic form, shape and size should be considered as important factors that influence the soil properties and mobility of heavy metals in soil.

“…The total As concentration in earthworms exposed to As(V)+MPs was signi cantly lower than that for As(V)-alone (Wang et al 2019). Therefore, co-exposure of MPs and heavy metals can precipitate synergistic, antagonistic, or intensifying effects on organisms (Cao et al 2021). However, there are relatively few studies on the co-exposure to MPs and heavy metals in marine organisms.…”

Microplastics constitute a new type of environmental pollutant with a particle size of less than 5 mm that can combine with heavy metals to enter organisms such as clams, and the impact of the combination of microplastics and heavy metals on the marine organism Ruditapes philippinarum remains unclear. Therefore, this problem is analyzed the effects of different concentrations (0, 0.1, 1, 5, and 10% w/w) of polystyrene (PS) and three heavy metals (arsenic (As), cadmium (Cd), and lead (Pb)) (20 and 200 µg/L) on the bioaccumulation of the heavy metals in clams, and the effects of time for PS (0, 1, and 5%)-bound As, Cd, and Pb (ACP). We found that different concentrations of PS exerted different effects on the absorption of heavy metals by clams. A low concentration of PS (0.1%, 1%) inhibited heavy-metal bioaccumulation, while a high concentration of PS (5%, 10%) promoted their accumulation. Whether or not PS was added, the concentration of As, Cd, and Pb in clams increased with time. The relative amount bioaccumulated in clams was As > Cd > Pb, and we demonstrated a correlation between the concentration of heavy metals in clams and the concentration of PS in seawater. When exposed to a low concentration of PS, the concentrations of As and Cd in clams diminished with the concentration of PS in sea water; and when exposed to high concentrations of PS, the concentrations of Cd and Pb in clams appeared also to be reduced with increasing PS concentrations.
