Review of research on impacts to biota of discharges of naturally occurring radionuclides in produced water to the marine environment

Dosimetric analysis of fathead minnow (Pimephales promelas, Rafinesque, 1820) exposed via ingestion to environmentally relevant activities of Ra-226 for two years

“…Exposure in the environment is chronic and the doses are low, further complicating the task of obtaining useful and relevant data (Smith et al 2011, Audette-Stuart et al 2012, Kryshev and Sazykina 2012, Vives i Batlle 2012. A literature search in this area revealed that there are very large data gaps (Beresford et al 2004, Garnier-Laplace et al 2004, Dallas et al 2012, Hosseini et al 2012) and that for many species and taxonomic groups there is no information at all about radioisotope uptake, transfer or effect. Fish as a group are relatively well studied.…”

Marine radioecology after the Fukushima Dai-ichi nuclear accident: Are we better positioned to understand the impact of radionuclides in marine ecosystems?

“…An important topic is discharges of produced water from oil and gas installations. Discharges of produced water from the petroleum industry are a multi-contaminant situation involving metals, radionuclides and organic compounds (Hosseini et al, 2012). As part of this, it is important to address the bioaccumulation and combined toxicity of the different components in produced water, both in the water column and in sediments, for various marine species.…”

Study on Strontium Mineralization by Thiobacilus Denitrificans for Remediation

“…Radioactive pollution is increasingly serious and radioactive pollution can not be repaired immediately once it breaks out. Strontium contamination is a research hot point as one of the typical radioactive pollution, and strontium contamination is easily found in the soil or water (Hosseini,et al, 2012). As an important radioactive nuclide in the fission products, strontium has long half-life and strong toxicity.…”
