Trace element concentrations in blood plasma or serum have been assayed by numerous investigators using a variety of analytical techniques. For several elements, figures obtained in different centers are widely disparate. Impressive evidence has accumulated that a great deal of the inconsistencies should be ascribed to unsuspected contamination of the samples with exogenous material during thei...

Different definitions of risk too easily lead to differences in the type and level of risk accepted by varying stakeholders involved in the remediation process and redevelopment of contaminated sites as a whole. This can be rooted in the way risk information is interpreted and evaluated: technical risk definitions are largely evidential and based on engineering or technical contents, whereas so...

Alkylphenol polyethoxylate (APEO) derivatives, such as nonylphenol monoethoxylate (NP1EO), nonylphenol diethoxylate (NP2EO), nonylphenol (NP) and octylphenol (OP), have been detected in the surface water, sediment, food and groundwater of numerous countries. Because groundwater is the main source of water for pig herds, the aim of this study was to measure the concentrations of APEO derivatives...

Introduction: Hospitals, as one of the important elements in the health system, play an important role in patient’s health. Fungi are one of the effective parameters on indoor air quality. This study aimed to compare of fungal contamination of two hospitals in Shiraz City. Materials and Methods: Sampling was conducted based on NIOSH 0800 standard (1.5 meters above the ground level with one sta...

This paper describes the building of an integrated simulation tool based on a systems approach, and its contribution to local political discussion of the mitigation of microbiological contamination of the water in a coastal area. Local management schemes view water quality as a high-priority environmental objective. In practice, how far this objective is achieved depends on trade-offs between t...

• excavating and removing all contaminated soil and disposing of the soil in an environmentally sound manner; • covering the site with a blanket of uncontaminated soil and installing a runoff control and drainage system to limit the potential contamination of surface water or groundwater; • other in-situ treatment methods that involve complex physical and/or chemical neutralization or extractio...

As a widespread problem, heavy metals contamination in soil has drawn considerable study interest, especially for the farmlands around mine area. A variety of pollution evaluation methods have been compared including both traditional physical and chemical analysis methods as well as ecological assessment methods. And the combination of multiple assessment methods was recommended to get a compre...

Digital technologies for cyber-physical systems are rapidly advancing, and the ubiquity of Internet Things (IoT) has created significant challenges academic, industrial, service applications due to high dimensionality, noise contamination, incompleteness, inconsistency, massive amounts data [...]

the risk of disease spread through water, fruits and vegetables contaminated through unclean waters varies from region to another. springs and underground water resources are essentially free of germs or they have tolerable levels of germs; unless they are infected by surface water or human excreta. scientific reports have shown that outbreaks of food-borne illnesses especially foods such as fr...
