Arsenate (As V) in water: Quantitative sensitivity relationships among biomarker, ecotoxicity and genotoxicity endpoints

Screening of high phytotoxicity priority pollutants and their ecological risk assessment in China’s surface waters

“…Even sublethal effects of pollutants on plants can have negative impacts on food production and natural vegetation (van den Brink et al, 1997). In addition, plants have a high capacity for bioconcentration and bioconversion, with potentially adverse health hazards to organisms higher up the food chain (Silva et al, 2013). Thus, besides the hazard to plants, the risk of pollutants on aquatic ecosystem should be evaluated comprehensively.…”

“…Toxicologists generally believed that the sensitivities of the aquatic plants to pollutants were lower than animals (Kenaga and Moolenaar, 1979;Silva et al, 2013). With that assumption, in the hazard assessment of environmental pollutants in aquatic ecosystems, the hazardous effects on aquatic plants have not attracted enough attention, and the toxicity tests for plants have been conducted less frequently than for animals (USEPA, 2001).…”

An integrated study on Gammarus elvirae (Crustacea, Amphipoda): perspectives for toxicology of arsenic-contaminated freshwater

“…Moreover, a detailed survey of waters along the Amaseno river (Ronci 2013; data partly extracted from http://www.arpalazio.gov.it) indicates that the chemical and biological quality of the water progressively deteriorates as the river flows downstream, probably owing to untreated agricultural and urban effluents along the river. Indeed, recent studies have shown that the pollution in aquatic environments may result in (geno)toxic effects and alterations in ecosystem functions (Silva et al 2013; among others). However, the way in which the composition of river water may be related to DNA damage levels is, despite being highly relevant to public health, not yet clearly understood.…”

A 3D ecotoxi-topological profile: Using concentration-time-response surfaces to show peroxidase activity in Zea mays (L.) exposed to aluminium or arsenic in hydroponic conditions

“…Thus, QSRs could be useful for regulatory purposes in the environmental management domain, because there are a lack of studies that could facilitate establishment of a numerical relationship range for chemical exposure among the responses observed at different levels of biological organization in the same or different species (Corrêa et al, 2006;Silva et al, 2013).…”
