Abstract:
... In this work, we report a newly developed paper-based analytical device (PAD) for determining formaldehyde in foods. Formaldehyde (FA) is considered as a carcinogen and classified as a Type 2 hazardous substance but it is still illegally use as a preservative in many foods to prevent them from spoilage and increase storage time. Current technologies for quantifying FA in foods are expensive, requi ...

Abstract:
... Pentachlorophenol (PCP) is ubiquitous and moderately persistent in the environment, and it is an identified human carcinogen. Previous animal experiments indicate that toxic mechanisms of PCP include oxidative stress. However, no epidemiological study has reported the association between PCP exposure and oxidative stress; such association in pregnant women, a vulnerable population, is of particula ...

Abstract:
... 1,4-Dioxane is a synthetic industrial chemical that is highly soluble in water and is generally considered an emerging water contaminant. The occurrence of 1,4-dioxane in water supplies is hazardous to humans, because 1,4-dioxane is classified as a probable carcinogen. Presently, there are no U.S. federal regulations for the maximum contaminant levels of 1,4-dioxane in drinking water, but several ...
... The detection of benzo(a)pyrene (BaP), a strong carcinogen, in edible oil has been widely reported. This work studied the concentration of BaP in different parts of tea seeds generated during roasting from a new perspective. A novel method was established and used to calculate the actual generated concentration of BaP, which is different from the previous direct determination of BaP concentration ...

Abstract:
... Arsenic (As) in rice is a crucial public health concern because it is a human carcinogen. This study was conducted to determine the actual As concentrations and estimate the probable range of As in rice. The status of As accumulation in rice was also determined. White (n=154) and brown (n=54) rice samples were collected over three crop years. The concentrations of As (total, bioaccessible and inor ...

Abstract:
... Hexavalent chromium (Cr(VI)), a known carcinogen, emanates from both anthropogenic and natural sources. A pilot study of the ambient Cr(VI) concentrations was conducted at the center of Aktobe which is a few kilometers away from major industrial chromium plants. Total Cr(VI) concentrations were measured in the fall and winter seasons with mean values (S.D) of 5.30 (2.16) ng/m³ and 2.26 (1.80) ng/m ...

Abstract:
... Peanuts are prone to mold when stored improperly, resulting in the production of aflatoxin, which is a potential carcinogen. Near-infrared hyperspectral imaging is an emerging technique for the nondestructive detection of food contamination. In this study, hyperspectral images (HSIs) of healthy and moldy peanuts were acquired for classification. A point-centered convolutional neural network combin ...

Abstract:
... Formaldehyde (FA), a reactive carbonyl species, is classified as Group 1 carcinogen by International Agency for Research on Cancer (IARC) in 2004. In addition, clinical studies have implicated that elevated levels of FA have been associated with different kinds of diseases, such as neurodegenerative diseases, diabetes, and chronic liver and heart disorders. However, in addition to the direct inhal ...

Abstract:
... Inorganic arsenic is a known human carcinogen and is routinely detected in US community water systems (CWSs). Inequalities in CWS arsenic exist across broad sociodemographic subgroups. Our objective was to evaluate the county-level association between socioeconomic vulnerability and CWS arsenic concentrations across the US. We evaluated previously developed, population-weighted CWS arsenic concent ...

Abstract:
... Nickel resources are abundant in the world, and the application of nickel in production and life is more and more extensive. However, excessive nickel entering the environment will not only cause environmental pollution but also seriously endanger plants, animals and human health. Nickel compounds are carcinogenic and have been classified as a class 1 carcinogen. Nickel mainly exists in the form o ...

Abstract:
... Ochratoxin A (OTA) is a possible human carcinogen commonly found in various agricultural commodities worldwide. While this potent nephrotoxin tends to survive common food processes and contaminate food products, certain process with higher temperature treatments may reduce OTA contents. Roasting has been suggested as a possible method to reduce OTA in coffee beans with up to 90% reduction, which m ...

Abstract:
... Table olive products can contribute to the nutritional intake of acrylamide; a compound classified as a probable carcinogen. For an exposure evaluation of acrylamide the analysis of market products is therefore important. However, it must be taken into account that olives are often used in heated meals e.g. pizza products, which is expected to affect the final acrylamide concentration. Here we pre ...

Abstract:
... Acrylamide (AA), a potential carcinogen, is commonly formed in foods rich in carbohydrates at high heat. It is known that AA-induced mitochondrial dysfunction is responsible for its toxicity. Previously we found AA exposure increased miR-27a-5p expression in livers of SD rats. Here, the regulation mechanism of miR-27a-5p in mitochondrial dysfunction was investigated in rat liver cell lines (IAR20) ...

Abstract:
... BACKGROUND: Ethyl carbamate (EC) is a potential carcinogen existing in fermented foods such as Chinese rice wine (Huangjiu). Since urea is an important precursor of EC, the degradation of urea could be an effective way to reduce EC in foods. RESULTS: In this study, an Enterobacter sp. R‐SYB082 with acid urea degradation characteristics was obtained through microbial screening. Further research iso ...

Abstract:
... Through a survey with European companies and expert interviews we study how REACH authorisation affects the phase-out of hazardous chemicals focusing on trichloroethylene, a well-studied solvent used in metal parts cleaning. We find that most of the firms have substituted trichloroethylene by perchloroethylene, which has similar chemical characteristics. This allows them to continue to use the sam ...
