The study evaluated the impact of wastewater irrigation (WW) on severity pollution and health risk potential Zn, Cu, Cd, Pb heavy metals in vegetables irrigated with WW versus those grown fresh water (FW) across different vegetable kinds. This multifaceted assessment was conducted using index (PI), ecological (ER), bio-concentration factor (BCF), hazard quotient (HQ), overall (HI), carcinogenic...

Air pollution control in the United States for five common pollutants--particulate matter, ground-level ozone, sulfur dioxide, nitrogen dioxide, and carbon monoxide--is based partly on the attainment of ambient air quality standards that represent a level of air pollution regarded as safe. Regulatory and health agencies often focus on whether standards for short periods are attained; the number...

Resistance to Meloidogyne arenaria race 1 is not currently available in commercial peanut cultivars. Moderate levels of resistance have been identified in Arachis hypogaea plant introductions (PI) in previous greenhouse studies. The purpose of this work was to evaluate the effects of resistance in peanut PI on populations dynamics of M. arenaria in field plots. The PI designated as resistant in...

In patients with HUS-N, TCD showed only slightly increased blood flow velocities of basal brain arteries ( table 1 ). However, the mean resistance index (RI) and in particular the mean pulsatility index (PI) were significantly increased in patients with HUS-N, compared to HUS patients without neurological symptoms (mean PI/RI 1.11/0.62 vs. PI/RI 0.72/0.48, p ! 0.001, Mann Whitney U test; table ...

In this paper the Wiener and hyper Wiener index of two kinds of dendrimer graphs are determined. Using the Wiener index formula, the Szeged, Schultz, PI and Gutman indices of these graphs are also determined.

BACKGROUND AND AIMS Perfusion index (PI) is a new parameter tried for predicting hypotension during spinal anaesthesia for the lower segment caesarean section (LSCS). This study aimed at investigating the correlation between baseline perfusion index and incidence of hypotension following SAB in LSCS. METHODS In this prospective observational study, 126 parturients were divided into two groups...

Heavy metal pollution significantly reduces the quality of environment and threatens human health, especially in industrial cities. This study investigated toxic metals concentrations, levels health risks assessment urban soils Yazd City, as an city center Iran. Soil surface samples (0–10 cm) were collected from 30 points area for geochemical analysis. The concentrations heavy determined using ...

Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for var...

OBJECTIVE To evaluate the usefulness of Color Doppler flowmetry in the prediction of intrauterine growth restriction (IUGR) in high-risk pregnancies. MATERIALS AND METHOD A total of 62 high-risk pregnant women underwent Color Doppler flowmetric umbilical artery pulsatility index (PI), resistive index (RI) and systolic/diastolic (S/D) ratio, middle cerebral artery PI, RI and S/D ratio, Ductus ...

Abstract Wabe River is a vital source of drinking water, irrigation for agriculture, and income the local residents. However, river's declining quality has led to an increase in waterborne infections made it appear muddier. The study's objective was evaluate river water using 23 different parameters calculate Weighted Arithmetic Water Quality Index (WAWQI), Metal (MI), Pollution (PI), Potential...
