Radiation-safety management condition in Japanese nuclear medicine facilities were investigated by the questionnaire method. The first questionnaire was asked in all Japanese 1,401 Nuclear Medicine facilities. Answers from 624 institutes (44.5%) were received and analyzed. The radiation-safety management in nuclear medicine institutes was considered to be very well performed everyday. Opinion f...

background: due to the lack of proper rail road and air transportation, most commutes in iran are carried out by buses. in most cases, the water in the busses is used for passengers for drinking usage. although this kind of water source has provided convince for the travelers, it could be a great risk in disease outbreak. the aim of this study is to determine the water quality in commuting buse...

Using molecular techniques, a longitudinal study was conducted with the aims at identifying the seasonal difference of Cryptosporidium contamination in surface water as well as analyzing the potential sources based on species information. One hundred forty-four water samples were collected, 72 samples from the Chao Phraya River, Thailand, collected in the summer, rainy and cool seasons and 72 s...

Aim: The present study was carried out to explore the potential source of contamination and the efficacy of different washing practices towards quality milk production. Materials and Methods: Probable sources of contamination viz. stored water, potable water, milker’s hands, milking pail, udder of individual buffalo and milk cans were subjected to different types of bacterial counts before the ...

A study was carried out to evaluate the water quality of Sargodha city water supply system. Water samples from four different sources (1 tubewell and 3 surface water sources) and eight house connections (2 from each source respectively) were collected making a total of twelve sampling points. Two set of samples, one before monsoon and one after monsoon were collected from each sampling point. A...

One of the UN sustainable development goals is to achieve universal access to safe and affordable drinking water by 2030. It is locations like Kathmandu, Nepal, a densely populated city in South Asia with endemic typhoid fever, where this goal is most pertinent. Aiming to understand the public health implications of water quality in Kathmandu we subjected weekly water samples from 10 sources fo...

BACKGROUND In South Africa there is little data on environmental pollution of rural water sources by agrochemicals. METHODS This study investigated pesticide contamination of ground and surface water in three intensive agricultural areas in the Western Cape: the Hex River Valley, Grabouw and Piketberg. Monitoring for endosulfan and chlorpyrifos at low levels was conducted as well as screening...

Water supplies and water distribution systems represent potential targets for terrorist activity in the United States because of the critical need for water in every sector of our industrialized society. Even short-term disruption of water service can significantly impact a community, and intentional contamination of a municipal water system as part of a terrorist attack could lead to serious m...

A screening in a sugar snap packaging company showed a converged build-up of aerobic psychrotrophic plate count (APC) (ca. 6.5 log CFU/100mL), yeasts and molds (Y&M), and lactic acid bacteria (LAB) (both ca. 4.5 log CFU/100mL) in the wash water in the absence of water sanitizer, and a low build-up of chemical oxygen demand (30 ± 5 mg O2/L) and turbidity (5.2 ± 1.1 NTU). Decontamination experime...

When heavy rainfall follows herbicide application, the intense surface runoff causes stream water contamination. Aquatic organisms are then briefly exposed to a complex mixture of contaminants. The aim of the present study is to investigate the genotoxic impact of such events on fish. A model fish, the Crucian carp (Carassius carassius) was exposed in controlled conditions, for 4 days, to water...
