Abstract:

Tritium is a byproduct of many radiochemical reactions in the nuclear industry, and its effects on aquatic organisms, particularly low-dose effects, deserve special attention. The low-dose effects of tritium on aquatic microbiota have been intensively studied using luminous marine bacteria as model microorganisms. Low-dose physiological activation has been demonstrated and explained by the signaling role of reactive oxygen species through the “bystander effect” in bacterial suspensions. The activation of microbial functions in natural reservoirs by low tritium concentrations can cause unpredic

Abstract:

During the period from 2019 to 2021, a series of experiments were carried out to study the uptake of tritium by crops in an area heavily contaminated with atmospheric tritium oxide (HTO), at the former Semipalatinsk test site in Kazakhstan. A quantitative assessment is given of the tritium uptake by typical crops (lettuce, tomatoes, peppers and beans) cultivated all over Kazakhstan in the case of a short-term tritium oxide vapor exposure. The plant samples were collected during and after exposure and analyzed for the tritium concentration in two chemical forms: tissue-free water tritium (TFWT)

Abstract The exchangeability of hydrogen atoms within organic molecules in vivo with ambient water hydrogen is uncertain. We assessed this by administrating the tracer deuterium to the fish. Flatfish were retained in deuterium-elevated seawater for 48 h, and the deuterium-to-hydrogen (D/H) ratios in the flesh samples were measured. Rapid in vivo equilibration between exchangeable organically bound hydrogen (Ex-OBH) and tissue-free water (TFW) hydrogen was indicated by the linear relationship between the D/H ratios of total organically bound hydrogen (t-OBH) and TFW.

Abstract. Understanding hydrogen dynamics in soil organic matter is important to predict the fate of 3H in terrestrial environments. One way to determine hydrogen fate and to point out processes is to examine the isotopic signature of the element in soil. However, the non-exchangeable hydrogen isotopic signal in soil is complex and depends on the fate of organic compounds and microbial biosyntheses that incorporate water-derived hydrogen. To decipher this complex system and to understand the close link between hydrogen and carbon cycles, we followed labeled hydrogen and labeled carbon througho

The variation of exchangeable Al is high and it depends on the changes of all forms of soil acidity and the degree of base cation saturation.

The amount present in each case is, however determined by climate, type of vegetation, topography, parent material and activities of man.

Application of Zn (0, 5 or 10 mg Zn kg−1 soil) without P application had no effect on DM yields of bean plants. However, Zn application in combination with P application resulted in significant DM yield responses. There was no evidence that the P-induced Zn deficiency was a res
