Aim: This research aimed to analyze the presence of microbial contamination and antibiotic residue in beef meat from city slaughterhouses in East Java Province, Indonesia. Materials and Methods: A total of 40 samples from city slaughterhouses were used in this study. The tests for microbial contamination used several methods including total plate count (TPC), most probable number of Escherichia coli, detection of Staphylococcus aureus using Mannitol Salt Agar media, Salmonella spp. detection using Bismuth Sulfite Agar media and Triple Sugar Iron Agar media, and detection of the antibiotic resi

This research work studied the impact of diesel oil contamination on the geotechnical properties of clay soil, which is crucial for understanding how such contamination can affect soil behavior in construction and environmental contexts. A series of tests were conducted to analyze key properties, including liquid limit (LL), plastic limit (PL), plasticity index (PI), specific gravity, bulk density, maximum dry density (MDD), and optimum moisture content (OMC) across various levels of diesel contamination. The findings reveal significant changes in the soil’s characteristics due to diesel conta

Honey is derived from plant nectar and pollen collected by bees. Honey contains natural sugars and nutrients but is prone to contamination by heavy metals such as mercury, copper, and cadmium from the environment. Honey quality standards stipulate maximum limits of contamination according to SNI 8664:2018. This study examined copper, mercury, and cadmium levels in native, cultivated, and branded honey using ICP-AES.

In this review, the mycotoxin contamination of Korean cereals and their products is analyzed by crop based on scientific publications since 2000. Barley, rice, and corn were investigated heavier than the others. The common mycotoxins occurred in all cereals and their products were deoxynivalenol and zearalenone. Nivalenol was detected in all samples analyzed but more frequently or mainly in barley, rice, and oat. Fumonisin was commonly detected in corn and sorghum but also in adlay, millet, and rice. Adlay and millet were similar in the contamination pattern that fumonisin and zearalenone were

Summary Mycotoxins, including aflatoxins, are pervasive contaminants in crops worldwide, with aflatoxin B1 being particularly significant due to its effects on agricultural production and food safety. Serbia has a well-developed crop production sector. The increasing risk of aflatoxin contamination in certain parts of Europe, particularly the Balkan Peninsula, became evident during the 2013 outbreak. This study presents the results of 14-year monitoring (2010–2023) of corn for the occurrence of aflatoxin B1 in the Republic of Serbia. A total of 1167 samples were analyzed, of which 422 samples

Mercury metal contamination in food is regulated in SNI number 7387 of 2009 regarding the Maximum Heavy Metal Limit. Some metal waste disposal ends up in river, lake, or sea waters so that metal pollution can occur in the ecosystem. This study aims to determine the levels of mercury metal contamination in canned tuna. Sample preparation was carried out using the wet digestion method with a microwave digestion device.

Ensuring the provision of high-quality drinking water in Bulgaria faces significant challenges, including an outdated and deteriorating water distribution network, anthropogenic pollution of water sources, and the natural migration of chemical elements from rock and soil substrates into groundwater. These factors contribute to water contamination, particularly the presence of harmful substances such as heavy metals, pesticides, and fertilizers, which pose risks to human health. Contamination of drinking water with chromium, especially in areas with naturally high levels, is of serious concern.

The AVR pebble bed reactor (46 MWth) was operated 1967–1988 at coolant outlet temperatures up to 990°C. Also because of a lack of other experience the AVR operation is a basis for future HTRs. This paper deals with insufficiently published unresolved safety problems of AVR and of pebble bed HTRs. The AVR primary circuit is heavily contaminated with dust bound and mobile metallic fission products (Sr-90, Cs-137) which create problems in current dismantling. The evaluation of fission product deposition experiments indicates that the end of life contamination reached several percent of a single c

Heavy metals (HM) can be defined as metallic elements that are greater than 40 in atomic weight and above 5 g/cm3 in specific gravity and cause abnormal effects on the biota at low concentrations. This study aimed to assess the levels of HM contamination in soils and unpolished rice grains (Oryza sativa) at three separated paddy cultivation fields in Anuradhapura, Gampaha, and Jaffna over one consecutive season. The concentrations of arsenic (As), cadmium (Cd), and lead (Pb) were detected using inductively coupled plasma mass spectrometry (ICP-MS). According to the results, HM concentrations o

Abstract. Crude oil contamination has been proven to adversely alter soil's geotechnical properties, which normally renders it unsuitable for use as road construction materials. Although researchers have extensively studied various ways of remediating and improving the properties of crude oil-contaminated soils (COCS), the differing results still make it a subject of interest. This study investigated the performance evaluation of the effects of ground granulated blast furnace slag (GGBFS) activated with a mixture of Sodium silicate and Sodium hydroxide on the strength of crude oil-contaminated
