“…The most abundant are usually radium-226 and radium-228 (Neff 2002). In this study 226 Ra ranged from <0.016 to 10.9 Bq L -1 and 228 Ra from <0.032 to 10.5 Bq L -1 which is similar to a previous study in Campos Basin, where the levels of these radionuclides ranged from 0.012 to 6.0 Bq L -1 for 226 Ra and from <0.05 to 12.0 Bq L -1 for 228 Ra (Vegueria et al 2002). Brazilian PW exhibits the same radioisotope levels as those reported elsewhere (E&P Forum 1994;Utvik 1999;Lysebo and Strand 1998;Guzella et al 1996).…”

Chemistry and toxicity of produced water (PW) from offshore platforms operated by Petrobras in Brazil were investigated. Three studies -PW monitoring, detailed composition and temporal variability -were conducted during 1996, 2001 and 2006 Median chronic toxicity using Lytechinus variegatus showed a NOEC = 1.3%. These results for Brazilian PW are similar to those for the North Sea, Gulf of Mexico, Australia and other regions of the world. Dispersion plumes modelled using CORMIX and CHEMMAP predicted that PW can be diluted rapidly after discharge and that permissible levels for all chemical parameters in seawater cited in the Brazilian Resolution CONAMA 357/05 are attained within 500 m of the discharge point. Over 10 years (1998-2010) of monitoring in the vicinity of the Brazilian platforms did not show alterations in sea water quality, supporting the predictions of the dispersion plume modelling. Despite no observed alteration in seawater quality around oil and gas production platforms, the authors recognize the importance of continuous evaluation of the impact of PW discharges from a risk assessment perspective, and studies of bioaccumulation and the use of biomarkers, among other initiatives currently implemented by Petrobras in areas with large volumes of PW discharge. Up to and including 2011, Petrobras remains the major producer of oil and gas in Brazil and the total discharge of produced water by the country is essentially the volume that is discharged by offshore Petrobras operations. In 2005, the average total volume of PW discharged offshore on the Brazilian coast was 73 million m 3 /year, representing less than 3% PW discharged onto other oceans worldwide.

“…Typical ranges or average values of the radium radionuclide concentrations in the formation or produced water from different oil fields, including the recent data, are listed in Table 7 [29,32,34,38,51,[53][54][55][56][57][58][59][60][61][62].…”

“…Because the radium radionuclide concentrations in that waste water are usually below the clearance levels (Table 8), it is recognized as a low specific activity waste and they may be injected into underground formations or disposed into the sea.

Radium isotopes 226Ra and 228Ra in seawater of the western Yellow Sea were measured by using the Mn-fiber adsorption -HPGe y spectrum method. The distribution features of the two isotopes have been studied. The activities of 226Ra and 22SRa are 2.72-5.57 Bqm 3 and 7.51-34.3 Bqm 3, respectively. The activities of 226Ra and 228Ra from surface to bottom for each depth profile station are comparable within the experimental error, but the mean activities decrease with distance from the shore. From the distribution data of 228Ra, the horizontal eddy diffusion coefficient was estimated at 29 • 106 cm 2 s-1.
