Numerical simulation on groundwater contamination by organoarsenic compounds in Kamisu City, Ibaraki Prefecture, Japan

The high prevalence of hepatitis E virus infection in wild boars in Ibaraki Prefecture, Japan

Hepatitis E virus (HEV) is known as a causative agent of zoonosis and food poisoning. Pigs and some species of wild animals, including wild boar, are known to be a reservoir of HEV. In this study, we investigated the situation regarding HEV infection in wild boars in Ibaraki Prefecture, Japan. Serum, liver and feces samples from 68 animals were collected, and the presence or absence of HEV geno...

Helicobacter pylori Infection among patients visiting a clinic in Kasama City, Ibaraki Prefecture.

We examined Helicobacter pylori infection in patients who visited the Iso Clinic (Kasama City, Ibaraki Prefecture) with abdominal complaints, and determined the prevalence of H. pylori infection by age, sex, endoscopic diagnosis, abdominal complaint, gastric mucosa, and living environment. Peptic ulcer disease was observed in 23.2% of the patients examined with endoscopy, but there was no assoc...

Determination of gaseous organic compounds in Hyogo Prefecture, Japan.

The aim of this study was to analyze gaseous organic chemicals (GOCs) of high traffic (Nishinomiya City: 979,987 vehicles/day) and low traffic areas (Miki City: 29,338 vehicles/day) by gas chromatography-mass spectrometry (GC-MS) and to evaluate general environment exposure by PAHs in GOCs. After air sampling using an OMNIPORE membrane filter (< 0.45 microm) and Porapak-QS, sorbents were extrac...

Two Dimensional Numerical Simulation of Groundwater Contamination in the Highway Environment

There are many factors that affect the groundwater contamination in the highway environment. This paper reports a 2-dimensional numerical simulation of the movement of contamination with water into the sub-grade and water table beneath a road to determine the major factors affecting transport of contaminants. The modelling parameters were assembled from various literature sources and 8 scenario...
