“…The Yenisei River is relatively low in stable P (though having large seasonal variations) leading to high bioaccumulation. A review by (Vakulovsky et al, 2004) has estimated the water-fish CR of stable P in the Yenisei River to be in the range 10 4 -10 5 l kg -1 , one-to two orders of magnitude greater than that measured for radioactive 32 P (Table 4). …”

Bioaccumulation of key short-lived radionuclides such as 131 I and 32,33 P may be overestimated since concentration ratios (CRs) are often based on values for the corresponding stable isotope which do not account for radioactive decay during uptake via the food chain.This study presents estimates for bioaccumulation of radioactive phosphorus which account for both radioactive decay and varying ambient levels of stable P in the environment.Recommended interim CR values for radioactive forms of P as a function of bioavailable stable phosphorus in the water body are presented. Values of CR are presented for three different trophic levels of the aquatic food chain; foodstuffs from all three trophic levels may potentially be consumed by humans. It is concluded that current recommended values of the CR are likely to be significantly over-estimated for radioactive phosphorus in many freshwater systems, particularly lowland rivers. Further research is recommended to fieldvalidate these models and assess their uncertainty. The relative importance of food-chain uptake and direct uptake from water are also assessed from a review of the literature. It can be concluded that food-chain uptake is the dominant accumulation pathway in fish and hence accumulation factors for radioactive phosphorus in farmed fish are likely to be significantly lower than those for wild fish.

“…32 P is used in research laboratories, medical procedures and industry that may lead to discharge into freshwater systems. The Krasnoyarsk Mining and Chemical Industrial Complex in Russia discharged significant amounts of 32 P in the Yenisei river that were found to have accumulated in fish, with P activities of 2.2 Bq/L in water and 2900 Bq/kg in fish found at 200 km from the industrial site 4 . In the Columbia River contaminated by the cooling water from the Handford plutonium reactors, the estimated level of 32 P in water between 1950 and 1971 varied from 0.1 to 7.7 Bq/L 5 and the activity of 32 P in fish was varied from 0.7 x 10 3 to 22 x 10 3 Bq/kg between 1962 and 1964 6 .…”

Subtle effects of radiation on embryo development of the 3-spined stickleback

et al. 2020

The Chernobyl and Fukushima nuclear power plant (NPP) accidents that occurred in and 2011 respectively have led to many years of chronic radiation exposure of wildlife. However, controversies remain on the dose threshold above which an impact on animal health occurs. Fish have been highly exposed immediately after both accidents in freshwater systems around Chernobyl and in freshwater and marine systems around Fukushima. The dose levels decreased during the years after the accidents, however, little is known about the effects of environmental low doses of radiation on fish health. The present laboratory study assesses the effects of an environmentally relevant dose range of radiation (0.1, 1 and 10 mGy/day) on early life stages of the 3-spined stickleback, Gasterosteus aculeatus.The cardiac physiology and developmental features (head width, diameter, area) of high exposed embryos (10 mGy/day) showed no significant change when compared to controls. Embryos exposed to the medium and high dose were slower to hatch than the controls (between 166 and 195 hours post-fertilization). After 10 days of exposure (at 240 hours post-fertilization), larvae exposed to the high dose displayed comparable growth to controls. High-throughput sequence analysis of transcriptional changes at this time point revealed no significant changes in gene regulation compared to controls regardless of exposure conditions. Our results suggest that exposure of fish embryos to environmental radiation elicits subtle delays in hatching times, but does not impair the overall growth and physiology, nor the gene expression patterns in the recently hatched larvae.
