Mercury was incorporated into soil in amounts: 0, 50, 100 and 150 mg Hg·kg−1of soil. Zeolite, lime and bentonite were used to alleviate the soil contamination. Plants cultivated in Hg-polluted soil showed growth inhibition even in the presence of bentonite, lime or zeolite. Under elevated doses of Hg, the yield of aerial mass and roots decreased. The soil amendments mitigated the adverse effect of contamination, with lime and bentonite having a more beneficial influence on the yield than zeolite. The incremental contamination with mercury led to an increase in the content of Hg in the biomass of the plants. A much higher content of Hg was found in roots than in aerial parts. The inactivating substances applied to soil to some extent limited the increase in the content of this metal in all plant organs. Lime proved to be most effective in this regard. An increase in the soil contamination with mercury caused an increased content of nitrogen and potassium in plant organs and a decrease content of phosphorus.","PeriodicalId":15733,"journal":{"name":"Journal of Environmental Science and Health, Part A","volume":"14 1","pages":"82 - 96"},"PeriodicalIF":0.0,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86092378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ion chromatography (IC) is a relatively low cost and efficient means to determine the anionic composition, however, the wide range in anionic content of these fluids poses a challenge to analytical methods developed for “natural” waters. We report here that the combination of UV and conductivity detectors increased detection sensitivity (e.g., 10–50 ppb) and expanded the number of anions detectable in a single sample run. Samples from four unconventional shale gas wells, two impoundments, nine conventional oil wells, two freshwater streams and mine drainage samples were analyzed in this study.

The spatial distribution pattern of all tested metals coincided with the locations of mining area and the most populated part of town (domestic sources and traffic), as well as wind direction. The contamination evaluation indicated that As, Cd, Ni and Pb in air originated from anthropogenic sources-industry, heating and traffic. The non-cancer health risk assessment showed that ingestion was the primary exposure route for all metals and that Pb, and As were the main contributors to non-cancer risks in both children and adults. HI values were calculated for children (HI = 2.34–4.15E-06), indicating that children will likely experience higher health risks compared with adults (HI = 2.67–4.73E-07).

These endmembers were used to evaluate the source contributions of natural surface and ground water samples. A total of 1,177 ground water and surface water samples were analyzed including high-quality source waters and waters suspected of being impacted by drilling and mining activity. We found the following chemical ratios resolved different sources of contamination: Mg/Na vs SO4/Cl; SO4/Cl vs Mg/Li; Br/SO4 vs Ba/Cl; and Br vs Mg/Li. While no single parameter or mass ratio pairing by itself was definitive it was possible to converge on a likely source of contamination using multiple lines of analytical evidence. Further, this process clarified sources in impacted samples where one or more parameters commonly considered diagnostic of specific sources (e.g., Br, Ba), were below detection limits (e.g., too dilute) or not tested for. Ultimately, movement of sample values within the mass ratio space allows tracking of changes in water quality and contamination source dynamics as the water chemistry evolves.","PeriodicalId":15733,"journal":{"name":"Journal of Environmental Science and Health, Part A","volume":"44 1","pages":"24 - 32"},"PeriodicalIF":0.0,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85226645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The PAHs in sediments were extracted using optimized microwave-assisted extraction (MAE) method. The quantification of sixteen (16) PAHs in sediments was done by gas chromatography-flame ionization detector (GC-FID). The levels of PAHs recorded in sediment samples from Blood River ranged between 0.015 and 3.25 mg kg−1. The concentrations of PAHs obtained in sediments from Mokolo River (0.047 to 52.7 mg kg−1) were higher than those recorded in sediments from Blood River. The PAHs ratios indicated that both pyrogenic and petrogenic could be the sources of these compounds in both rivers. Toxic equivalency factors (TEFs) and benzo(a)pyrene equivalent (BaPE) were used to estimate the potential human health risk of PAHs in quantitative terms.

However, the induced cancer risks and differences among multisite cancers have not been well-understood. In this study, the concentrations of low-level arsenic in drinking water in XP city, Northwest China were investigated. A health risk assessment was carried out for different age groups and exposure pathways based on Monte Carlo simulations and disability-adjusted life years (DALYs). The measured arsenic levels were in the range of 7.61–9.25 μg/L with a mean of 8.23 μg/L. For the public, the average total lifetime cancer risk was 3.87 × 10−4, and the total DALYs estimation for all age groups was 20.58 person-year. The average individual DALYs lost was 3.35 × 10−5 per person-year (ppy), which was 33.5 times the reference value (1.00 × 10−6 ppy). The mortality burden had a considerably larger contribution (97.31%) to the total disease burden, and the 60–65-year age group exhibited the largest DALYs lost. Skin cancer exhibited the largest burden of 2.15 × 10−5 ppy, followed by lung cancer (1.20 × 10−5 ppy). This study might be useful for potential strategies of risk control and management in XP drinking water.","PeriodicalId":15733,"journal":{"name":"Journal of Environmental Science and Health, Part A","volume":"1 1","pages":"63 - 70"},"PeriodicalIF":0.0,"publicationDate":"2020-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80837911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By 16S rDNA sequence, cell morphology and biochemical characteristics the strains PDB2, PDB13, PDB16, and PDB26 were identified as Acinetobacter sp., Acinetobacter junii, Pseudomonas citronellolis, and Bacillus cereus, respectively.

In growth kinetic study Edwards and Aiba model, rather than the most popular Haldane model, gave the best fit indicating behavioral divergence of these strains with those from petroleum contaminated environments.
