“…Natural sources of arsenic to marine environments include freshwater inputs and atmospheric deposition of arsenic-containing particulates from pedogenetic weathering, volcanic emissions and forest fires as well as release from hydrothermal vents in deep-sea environments (Bissen and Frimmel 2003;Smith et al 2003;Morales-Simfors and Bundschuh 2022). Mobilisation of arsenic into seawater from estuarine sediments and coastal acid-sulfate soils occurs as a result of physical disturbance and changing redox conditions (Cullen and Reimer 1989;Johnston et al 2010).…”

High-quality ecotoxicology data are required to derive reliable water quality guideline values that ensure long-term protection of marine biota from arsenate. Tropical and temperate marine biota have sensitivity to arsenate covering three to four orders of magnitude due to the range of arsenate detoxification mechanisms used to reduce toxicity. The water quality guideline values derived in this study will contribute to robust risk assessments of arsenate in marine environments.
