Abstract:

Abstract Seawater is used to produce salt. For 10–15 years, geomembrane plastic has been used in salt fields in Indonesia to prevent contamination and increase quality and productivity. However, it is unfortunate that currently, seawater has been polluted by plastic waste, which has degraded gradually into small pieces about <5 mm in size called microplastics. In addition to microplastics, seawater is also polluted by heavy metals. Previous research indicated that the north coast of Central Java has been polluted by heavy metals whose content exceeded the threshold. The aim of this study wa

Abstract:

Complex permittivity measurements combined with artificial neural networks (ANNs) are investigated as a method for assessing and identifying heavy metal contamination in soil. The measurements are carried out with a custom-built device on 164 compacted samples of a natural clayey soil, artificially contaminated with various simple salts including heavy metals (Cu, Zn, and Pb). The soil samples are prepared by mixing solutions of the various salts with the soil at various concentrations and water contents. A database has been set up consisting of complex per mittivity measurements made between

The contamination of toxic heavy metals in meat production and processing can cause the oxidative deterioration of processed meat products.

Therefore, the objective of this study was to determine the influence of the intentional contamination of toxic heavy metals on the oxidative deterioration in ground pork models during aerobic display storage.

Abstract:

Heavy metals enter the soil in the form of oxides and salts (both soluble and practically insoluble in water). There is an assumption that heavy metal oxides are fixed mainly in the solid phase of the soil, especially in a neutral or alkaline pH environment. It should be noted that their toxic effect depends entirely on such factors as the type of soil and the pH of the pore solution. The behavior of heavy metals in soils is significantly different from the behavior of most cations of macroelements.

Heavy metal shadowing is one of the oldest and most useful methods of enhancing the contrast of biological molecules for visualization by electron microscopy.

Two methods commonly employed today are glycerol spraying/vaccuum evaporation and freeze-drying. While glycerol spraying is the easier method of the two, it does not significantly prevent collapse artifact during air-drying and thus is

Abstract:

Heavy metals are chemical elements with high density and atomic weight. Despite their widespread use in various industries and applications, they pose significant risks to the environment and public health if not handled properly. This study was conducted to estimate the concentration of some different elements in different types of cakes, where cake samples were collected from different shops from Al-Bayda city, the study dealt with six types of cakes. Flame photometer was used to estimate sodium and potassium salts and spectrophotometer to estimate heavy elements. The samples were digested u

With the contest of urbanization and industrial development, electroplating industries have grown rapidly. The different chemicals, metal salts and discharge of large volume of wastewater with inefficient treatment facilities had created the pollution load on water bodies. The present study was carried out to investigate the assessment of the monthly variation of pH and heavy metals (Cr, Ni, Zn, Fe) of electroplating untreated industrial wastewater from the selected study sites viz.

Background. The existence of lead-contaminated consumer products is a global issue. Toys and low-cost jewelry may contain toxic metals and Cambodia is known to have consumer products with toxic metals. Objectives. It is important to inform Cambodians about sources of toxic metals so that they can reduce their exposure risk, particularly for children. Methods. Student volunteers purchased, or brought from home, low-cost jewelry and toys to either the University of Health Science or a Don Bosco Institute in Phnom Penh, Cambodia, where they were analyzed using X-ray fluorescence (XRF).

Abstract:

Domestic water purification devices (point-of-use) are important choices for people to deal with sudden drinking water contamination. Especially for sudden heavy metal and arsenic contamination, home water purification units can play a key role as a secondary line of defense. Most of the arsenic removal studies are limited to meeting the requirements of local water quality standards and few studies have been conducted on arsenic removal from household water purifiers. In this paper, the distribution characteristics of arsenic in water at the end of the pipeline network in the Shanghai water su
