Long-term trace element assessment after a mine spill: Pollution persistence and bioaccumulation in the trophic web

Trophic transfer of heavy metals along a pollution gradient in a terrestrial agro-industrial food web

“…Existing research evidenced the large range of impacts of these pollutants in terrestrial organisms, including alteration of enchytraeid communities (Kapusta and Sobczyk, 2015), oxidative stress in the white garden snail (Radwan et al, 2010) and the black smith tree frog (Zocche et al, 2014), alteration of biomolecules in the leguminous plant Pisum sativum (El-Amier et al, 2019) and elicitation of stress response proteins synthesis in plants (Hasan et al, 2017). The diversity of living organisms and trophic guilds exposed to heavy metals (Grześ, 2010;Żmudzki and Laskowski, 2012;Fuentes et al, 2020) requires additional research efforts to better understand and describe the way heavy metals can affect organisms across trophic levels. It is crucial to consider the effects of heavy metal pollution in a trophic web context, as the pollutants may have little to no effects on primarily exposed species, while their effects may increase along the food chain.…”

Pollution Status And Risk Assessment Of Trace Elements In Portuguese Water, Soils, Sediments And Associated Biota: A Trend Analysis From The 80s To 2021

“…Environmental pollution is among the main challenges of today's society and is a major source of living organism's health problems (Guerranti et those originated from anthropogenic activities as industry (e.g., re neries, coal burning, petroleum combustion, nuclear power stations among others), agriculture, pharmaceutical, domestic e uents, and atmospheric sources (Figure 1) (Fuentes et al 2020, Liu et al 2020, Mandal &Kaur 2019. Most living organism's exposure results from human activities though environmental contamination can also occur through metal corrosion, atmospheric deposition, soil erosion of metal ions and leaching of heavy metals, sediment re-suspension and metal evaporation from water resources to soil and ground water (Figure 1) (Moiseenko et al 2019, Zhang et al 2014).…”

“…In fact, sediments can behave as both reservoir and non-point source of trace elements in the water column contributing to their persistence and recalcitrance in the aquatic environment (Chon et al 2012, Ribeiro et al 2018). Exposed organisms may absorb dissolved elements from surrounding water and food, and / or accumulate in various tissues in signi cant amounts causing harmful effects or entering in the food web (Fuentes et al 2020, Li et al 2018. Trace elements bioavailability is in uenced by physical and chemical factors (e.g., temperature, phase association, adsorption, speciation at thermodynamic equilibrium, complexation kinetics and solubility), climatic factors and biogeochemical cycling.…”

New Approach for the Evaluation of Ecological Quality in the Mediterranean Coastal Ecosystems, Case Study of Bizerte Lagoon: Marine Nematodes Functional Traits Assessment

“…All these compounds can enter marine ecosystems through a variety of routes, including urban (parking lots and residential areas) and agricultural (treated agricultural areas) runoff, washout or spray drift, or of contaminated sediments. Once these pollutants arrive in aquatic ecosystems, they can persist for a few months to several years [7,8].…”
