Initial sampling results of emerging contaminants at the Llobregat delta deep aquifer (Barcelona, Spain) are presented. Among micro contaminants selected are 82 pharmaceuticals (antibiotics, lipid regulation agents, analgesic/anti-inflammatory drugs, etc), 18 personal care products (sunscreen agents, preservatives and disinfectants/antiseptics), 4 metals, 44 pesticides, 6 volatile priority poll...

An approximation is obtained for the recession of a sloping aquifer. The analytical approximation can provide a useful tool to analyze data and obtain physical properties of the aquifer. In contrast to the case of a horizontal aquifer, when plotting the time derivative of the flux versus the flux on a log scale, the result shows that the flux derivative reaches a minimum value and that the curv...

Protection of ground water for present and future use requires monitoring and understanding of the mechanisms controlling long-term quality of ground water. In this study, spatial and temporal trends in concentrations of nitrate and pesticides in ground water in the eastern San Joaquin Valley, California, were evaluated to determine the long-term effects of agricultural and urban development on...

Transmissivity is an important hydraulic parameter to determine the amount of water passed horizontally across a given saturated thickness of an aquifer. The techniques to quantify this parameter, such as grain size analyses or pumping tests, can have limitations of time/spatial scale, viability, or economically. One technique that can be used, but little adopted, is the capture zone analysis. ...

[1] The Martian outflow channels were carved by the eruption of catastrophic floods from groundwater aquifers. This study models the time evolution of a typical outflow channel flood originating within a chaos region. The flood initiates when superlithostatic pore pressures within a confined aquifer lead to the propagation of hydrofractures through the confining cryosphere to the surface. The p...

A shallow aquifer with different redox zones overlain by intensive agricultural activity was monitored for the occurrence of 1,2-dichloropropane (DCP) to assess the fate and origin of this pollutant. DCP was detected more frequently in groundwater samples collected in aerobic and nitrate-reducing zones than those collected from iron-reducing zones. Simulated DCP concentrations for groundwater e...

BACKGROUND & PURPOSE Humans act as an intermediate host for Toxocara canis and Toxocara cati. Toxocara may be an important risk factor for asthma in humans. The aim of the present study was to evaluate immunoglobulin G (IgG) anti-Toxocara canis antibody, using enzyme-linked immunosorbent assay (ELISA) in asthmatic patients (aged 5-15 years), referring to a clinic of pulmonary diseases in Arak, ...

BACKGROUND The objective of this study was to investigate HLA-DRB1*and DQB1* allelic polymorphisms in Iranian patients with hydatidose. This is the first survey dealing with the correlation between HLA-DRB1* and DQB1* alleles and cystic echinococcosis in Iranian patients. METHODS The study was carried out on 56 patients with confirmed cystic echinococcosis and 30 apparently healthy individual...

BACKGROUND This study aimed to determine the effects of the interventions of Isfahan Healthy Heart Program (IHHP) on the type of oil consumed at the population level. It also tried to assess how this strategy has been effective as a health policy. METHODS The IHHP, a six-year community intervention program (2001-07), aimed at health promotion through the modification of cardiovascular disease...

The purpose of this paper is to construct perfect samplers for length-interacting Arak–Clifford–Surgailis polygonal Markov fields in the plane with nodes of order 2 (V-shaped nodes). This is achieved by providing for the polygonal fields a hard core marked point process representation with individual points carrying polygonal loops as their marks, so that the coupling from the past and clan of ...
