Chemical analysis dataset for contaminants of emerging concern and bioanalytical data for samples from a low mountain stream in Central Germany
<p>In 2022, river-water samples were collected at six sampling sites along the Holtemme River in Central Germany using large-volume solid phase extraction. The extracts were analysed by target chemical analysis for contaminants of emerging concern. In addition, the extracts were analysed in a bioanalytical test battery using effect-based tools. The battery included assays for cytotoxicity (neutral red retention assay), oxidative stress (Nrf2-CALUX®), endocrine disruption (ER-, AR-, anti-ER-, anti-AR-, GR- and PR-CALUX®) and the fish embryotoxicity test with zebrafish (<em>Danio rerio</em>). The data obtained are included in the .csv files in this repository.</p>

<p>The total concentration of trace elements analysis (of Al, As, Cd, Co, Cr, Cu, Fe, K, Li, Mn, Mo, Ni, Pb, Sb, Sn, Sr, Tl, Zn) was determined using ICP-ES for 50 samples and BCR sequential extraction for 20 samples.</p> <p>This research was funded by National Science Centre, Poland MINIATURA-5 2021/05/X/ST10/00673 “Post-remediation evaluation of contaminated site using geophysical methods”.</p> <p> </p>
IscoKin database of rate constants for reaction of organic contaminants with the major oxidants relevant to In Situ Chemical Oxidation
<p>Database of second-order rate constants for aqueous phase reaction of organic contaminants with the major oxidants involved in groundwater remediation by In Situ Chemical Oxidation (ISCO)—including permanganate, hydroxyl radical (from activated peroxide), and sulfate radical (from activated persulfate)—plus other comparable oxidants of environmental interest (carbonate radical, chlorine dioxide, and ozone).</p> <p>The data were compiled between 2003 and 2005 by Rachel Waldemer, Jaimie Powell, and other students under the direction of Professor Paul G. Tratnyek at the Oregon Graduate Institute in Beaverton, Oregon, USA. In 2006, a script written by Kaylie Langley was used to make the data available online via an interface that allowed searching by chemical name, CAS-RN, etc. The result was named the “IscoKin” database and was available at http://cgr.ebs.ogi.edu/iscokin/search.php until the server was retired in 2019.</p> <p>In place of IscoKin, we have made all of the data available as a spreadsheet in .xlsx format. The file includes two sheets, the first contains one “recommended” rate constant for each combination of organic compound and oxidant (i.e., one row per compound). The second sheet contains all of the individual rate constants that were compiled (i.e., one row per experimental result).</p> <p>The "best" value is most often an average of the individual values listed in the "All_values_with_references" sheet; but occasionally this value represents a single value, usually the "best" value given in Buxton et al. (1988) “Critical review of rate constants for reactions of hydrated electrons. hydrogen atoms and hydroxyl radicals (•OH/•O-) in aqueous solution” J. Phys. Chem. Ref. Data. 17, 513-886.</p> <p>While the database was checked thoroughly, it still is unlikely to be completely accurate or complete. For critical applications, we recommend tracking down the primary sources (listed in the spreadsheet) and use them for data, conditions, and other caveats. Obviously, we do not accept any responsibility for what anyone does with information obtained from this document.</p> <p>The work was funded by the Strategic Environmental Research and Development Program (SERDP), under grant number ER-1289, titled “Improved Understanding of In Situ Chemical Oxidation”. More details on this work can be found in Part 1 of the final project report, which is located at https://www.serdp-estcp.org/Program-Areas/Environmental-Restoration/Contaminated-Groundwater/Persistent-Contamination/ER-1289/.</p>

<p>This dataset was generated within the PRISMA project (Marie Skłodowska-Curie Grant Agreement No. 101110615) for assessing the health impact for adult consumers from 25 European countries due to dietary exposure to chemical contaminants and consumption of food based on different dietary patterns.</p><p>The risk coefficients used to generate data are presented in Table S1.</p><p>File S2 presents the health impact based on the chronic dietary exposure to chemical contaminants for each country.</p><p>File S3 presents figures regarding the health impact for each country for adult consumers due to dietary exposure to chemical contaminants and consumption of food based on different dietary patterns.</p><p>File S4 presents the health impact based on the consumption of unprocessed red meat, processed meat, and legumes for each country.</p><p> </p>
Results from national testing programs on the occurrence of chemical contaminants in food and feed - Switzerland
<p>In the framework of Articles 23 and 33 of Regulation (EC) No 178/2002 EFSA has received from the European Commission a mandate (M-2010-0374) to collect all available data on the occurrence of chemical contaminants in food and feed. These data are used in EFSA’s scientific opinions and reports on contaminants in food and feed. </p> <p>The presence of unauthorised substances or chemical contaminants in food may pose a risk factor for public health and can cause a negative impact on the quality of food. </p> <p>Commission Recommendations and Regulations on occurrence monitoring are in place for several contaminants of interest, some of which can be found here below: </p> <ul> <li>Commission Regulation (EU) 625/2017, on the application of food and feed law</li> <li>Commission Delegated Regulation (EU) 2022/931</li> <li>Commission Implementing Regulation (EU) 2022/932</li> <li>Commission Regulation (EU) 2023/915, on maximum levels for certain contaminants in food and repealing Regulation (EC) No 1881/2006</li> </ul> <p>These datasets contain the results of sampling that was designed according to national testing programs for a variety of contaminants in food and feed, as reported under the Chemical Monitoring Data Collection 2023 split by sampling year (data element ‘sampY’). </p> <p>More details are available in last year's finalised call for data ‘<a href="https://www.efsa.europa.eu/en/call/call-continuous-collection-chemical-contaminants-occurrence-data-food-and-feed-2023">Call for continuous collection of chemical contaminants occurrence data in food and feed | EFSA (europa.eu)</a>’.</p> <p>REPORTING AUTHORITIES CONTRIBUTING TO EACH DATA COLLECTION: </p> <p>OCC-CHEMMON2023 – Federal Food Safety and Veterinary Office</p>

Data from: Effect of chemical additives on electrokinetic remediation of Cr-contaminated soil coupled with a permeable reactive barrier
Chromium(Cr) contamination in soil, especially Cr(VI) has a serious threat to the environment and human health. The electrokinetic remediation (EKR) is a promising technology to remediate the Cr(VI). Therefore, EKR coupled with a permeable reactive barrier (PRB) was used to treat the Cr(VI) contaminated soil in this study. The CTMAB-Z, a modified zeolite (prepared by cetyl trimethyl ammonium bromide) alone and a mixture of CTMAB-Z and Fe(0) were used as PRB-1 and PRB-2 reactive media, respectively. The effect of chemical enhancers/additives i.e. dl-tartaric acid and tween 80 on EKR of Cr(VI) was also analysed in the contrasting experiments. While, the effects of repair time, voltage gradient and dl-tartaric acid concentration on Cr(VI) remediation were investigated by utilizing multifactor orthogonal experiment which was based on contrasting experiments. The contrasting experiment results showed that the highest Cr(VI) removal rate(66.27%) and leaching efficiency(71.29%) were observed in the experimental group which had dl-tartaric acid and PRB-2. Furthermore, the multifactor orthogonal experiment results had depicted that the highest Cr(VI) removal rate(80.92%) and leaching efficiency(85.25%) were achieved after treating the samples at a voltage gradient of 2.5 v/cm for 8 days in presence of 0.15 M concentration of dl-tartaric acid. This study demonstrated that Cr(VI) remediation through EKR process could be significantly enhanced by the use of PRB and additives.
