Uranium content in drinking water limescale and children’s hair in the Republic of Bashkortostan, Russia
Analysis of limescales, collected from the walls of kitchenware used to boil drinking water, were used as a surrogate for analysis of uranium in drinking water. Geological features of the territory mainly explained the spatial distribution of uranium concentrations in the samples. Furthermore, uranium was analysed in human hair samples from inhabitants of the region. The median concentration of U in drinking water limescale was 5.4 μg/g (range 0.…
Ecotoxicological and Microbiological Risk Assessment of Groundwater from Dimba Cave, Democratic Republic of the Congo
Dimba Cave is a large array of natural galleries in limestone mountains of the Democratic Republic of the Congo that contains highly valued pre-historic archaeological artifacts. The cave attracts a high number of tourists every year and is used by local populations as a water supply source. The main objective of the research undertaken in Dimba Cave consisted of assessing the quality of water and sediments from Dimba Cave ponds through evaluatin…
Environmental radioactivity in gold mining in Burkina Faso and potential recycling of mining waste rocks
Naturally occurring radionuclides have been reported to occur in high concentrations in gold deposits and with other metal ores in Africa. These radionuclides can be released during mining operations and ore processing, causing harmful radiation exposure of mine workers and nearby populations, and may render the mining waste rocks unusable. One large gold mine site in Burkina Faso, near Mana Village, was assessed for naturally occurring radionucl…
Impact of Environmental Radiation on the Incidence of Cancer and Birth Defects in Regions with High Natural Radioactivity
Four regions of high natural radioactivity were selected to assess radionuclide levels in rocks and soils, ambient radiation doses, radon exhalation from the ground, and radon concentrations in the air. The regions have different geochemical characteristics and radioactivity levels, which modulate the radiation exposure of local populations. Combining radiometric data with data from regional health statistics on non-infectious diseases, a statist…
Enhanced Polonium Concentrations in Aerosols from the Gulf Oil Producing Region and the Role of Microorganisms
This study provides the first data set of 210 Po and 210 Pb activity concentrations in the organic and inorganic components of several particle size classes of aerosols collected at two sampling stations in Kuwait. The 210 Po concentrations in the aerosols (Bq/g) were similar in all of the particle size classes, but as most (91%) of the aerosol load was made of fine fraction particles of PM 0.39-2.5 μm , most of the 210 Po activity was carried by…
Conservation of the last savannah animals in West Africa
The fauna of savannah in West Africa has considerably reduced over the last century. To conserve the fauna, particularly the large mammals, a cross-border nature preserve was created years ago, the W Park in Niger. Travelling through the Park to assess the wealth of wildlife revealed an abundant fauna of antelopes, buffaloes, elephants, hippos and lions, and many other species. There are important areas of archaeological interest within the Park,…
Glyphosate, the herbicide that become a nightmare and the Precautionary Principle
Glyphosate, known by the trademark Roundup®, is the most popular herbicide today and is used for weed control on agricultural fields and city streets. The exposure of human beings to glyphosate, even when they do not manipulate this chemical, is very widespread. Several studies have shown that this compound is now present in common foods, water, and in the urine of a large part of the population. Results of several assessments point to glyphosate…
Uranium mining and milling
Environmental radioactivity monitoring programmes are now implemented in many countries around legacy uranium mining and milling sites and current uranium mining sites and include, for example, the analyses of soil, plant, meat and water samples. Often, there are legal requirements on periodic reporting of this monitoring. The results are used to assess compliance with the standards for radiation exposure of the public. To provide quality assuran…
Radioactivity of anthropogenic origin in the Tejo Estuary and need for improved waste management and environmental monitoring
The Tejo Estuary is a large water body surrounded by seven municipalities and industries with liquid effluent discharges containing contaminants that reach the estuary. This is the case for man-made radionuclides used in nuclear medicine, present in liquid effluents discharged by medical facilities. Radionuclide measurements in seaweeds, mussels, fish, water and sediments sampled along the North bank of the estuary revealed the presence of 131I a…
Chlorinated hydrocarbons in sediments from Manila Bay, the Philippines
Polychlorobiphenyls (PCBs) and organochlorine pesticides were analysed in sediments collected during the summer monsoon period (rainy season) in order to assess the contamination of Manila Bay. Results were compared with previous determinations made during the winter monsoon period (dry season) in order to evaluate seasonal fluctuation of contaminant levels in the Bay. In both seasons, PCBs were present in concentrations higher than chlorinated p…

Worldwide intercomparison on the determination of chlorinated pesticides, PCBs and petroleum hydrocarbons in a mussel tissue homogenate, IAEA‐142
A mussel tissue homogenate, labelled IAEA‐142, was used as an intercomparison sample for the analyses of organochlorine pesticides, polychlorinated biphenyls (PCBs) and petroleum hydrocarbons. The sample material was analysed by 95 laboratories in 54 countries, which represents the widest participation ever obtained in an interlaboratory comparison exercise for synthetic organic contaminants in marine samples. The results reported by the laborato…
Monitoring of the mediterranean sea pollution (med pol) and data quality assurance
The concerted effort to monitor contaminants and to assess pollution in the Mediterranean Sea was agreed upon by the riverine States with a Programme named MED POL, part of the Barcelona Convention signed up in 1975. For near 25 years, this Programme has been the cornerstone of the Mediterranean Action Plan and has been instrumental to develop the capabilities of the countries to measure and assess marine pollution. Through cooperation with the I…
