Correction to: Natural uranium isotopes and 226Ra in surface and groundwater from a basin of a semiarid region in Brazil

The soil-to-plant transfer factors of natural uranium isotopes (238U and 232Th) were studied in Luong My tea farm, Tan Thanh district, Luong Son commune, HoaBinh province. The activity concentrations in leaves, trunk and root were determined for the tea tree at no harvest period (winter break). The measurements were carried out using gamma spectroscopy with high puritygermanium detector HPGe. Research results show that the activity of 238U and 232Th is higher in leaves than in trunk and roots.Soil-leaves transfer factor (TF) for238U and 232Th were as follows:TFU238 = 0,52 – 0,87; TFTh-232 = 0,25 – 0,43.

The Mediterranean

High precision measurements of natural uranium isotopes in the Atlantic Ocean, Mediterranean Sea, and Black Sea reveal isotopic makeups which differ significantly from the well-known oceanic composition. In the Mediterranean, water masses are strongly differentiated to the extent that they are able to be fingerprinted on the basis of &#948;234U. Mediterranean deep water masses show the highest enrichment, with an offset with respect to oceanic &#948;234U values of just over 1 &#8240;. The Black Sea shows an even higher offset of up to ~40 &#8240;. This offset provides an opportunity to look into the as of yet largely unstudied uranium inputs to the Mediterranean, in particular rivers and submarine groundwater discharge (SGD), which are thought to play key roles in uranium input to the global ocean. A simple box model, incorporating the Mediterranean and Black Sea data from this study is constructed to provide a first estimate of the U concentration and &#948;234U signature of rivers and SGD necessary for this offset to arise. These estimates are then compared with new measurements of various coastal and submarine springs from along the French Mediterranean Coast as well as with existing riverine data exists to speculate on which inputs may be most responsible for this offset.

Radium Activity

This paper deals with the analysis of natural radionuclide content in 23 water samples collected in the vicinity of the Nikola Tesla B thermal power plant, Serbia. All samples were analyzed for 226Ra and uranium isotopes (238U, 234U) activity using radiochemical methods and alpha spectrometry. Obtained results show that the activity concentrations for uranium and radium in the water around the thermal power plant are low when compared to those from areas across Serbia with their enhanced natural uranium and radium content. No important radiological hazard related to uranium and radium activity stored in heap was found.

Carried out ecological and hygienic assessment of pollution of surface and groundwater of mining areas in the Republic of Bashkortostan. Revealed exceeding standards for fishery water bodies and drinking and cultural and community water use, which indicates the potential danger of surface water for the health of the region's population. The greatest relative contribution to the overall pollution of surface water bodies are making manganese (33,0–66,6 %), iron (9,1–15,6 %), calcium (6,5–11,7 %), lead (5,8– 7,2 %). The quality of water used for drinking purposes from decentralized water sources (boreholes, wells, springs), do not always correspond to the hygienic and sanitary-epidemiological requirements. In this case, the highest priority performance of drinking water contamination are increased stiffness, high content of iron, calcium, nitrate, presence cadmium, and hexavalent chromium.

The Nomini Creek Watershed/Water Quality monitoring project was initiated in 1985, as part of the Chesapeake Bay Agreement of 1983, to quantify the impacts of agricultural best management practices (BMPs) on improving water quality. The watershed monitoring system was designed to provide a comprehensive assessment of the quality of surface and groundwater as influenced by changes in land use, agronomic, and cultural practices in the watershed over the duration of the project. The primary chemical characteristics monitored include both soluble and sediment-bound nutrients and pesticides in surface and groundwater. Water samples from 8 monitoring wells located in agricultural areas in the watershed were analyzed for 22 pesticides. A total of 20 pesticides have been detected in water samples collected. Atrazine is the most frequently detected pesticide. Detected concentrations of atrazine ranged from 0.03 - 25.56 ppb and occurred in about 26 percent of the samples. Other pesticides were detected at frequencies ranging from 1.6 to 14.2 percent of all samples collected and concentrations between 0.01 and 41.89 ppb. The observed concentrations and spatial distributions of pesticide contamination of groundwater are compared to land use and cropping patterns. Results indicate that BMPs are quite effective in reducing pesticide concentrations in groundwater.
