A protocol, adapted from the QuEChERS method, originally designed for the extraction of pesticides in fruits and vegetables, in combination with gas chromatography-triple quadrupole mass spectrometry was developed to assess the bioavailability of polycyclic aromatic hydrocarbon extraction at low levels in soils to the soil quality bioindicator Cantareus aspersus. Bioaccumulation was measured in snails exposed ex situ for 28 days under controlled conditions to soils lightly or highly contaminated (sum of 16 molecules in the range 3.32–140 mg kg−1 dry weight). The method was validated (low limits of detection, linear calibration curves, good precision and trueness) and found to be efficient to show that strongly contaminated soils were not necessarily those that presented the highest bioavailable organics concentrations. This methodology offers a tool to assess the environmental risk of contaminated soils and to prioritize the management of polycyclic aromatic hydrocarbons-contaminated soils.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"61 1","pages":"209 - 223"},"PeriodicalIF":0.0,"publicationDate":"2020-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78322200","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}

Boron levels ranged between 0.001 and 5.5 mg/L. The lowest boron levels were in Trabzon, the highest in Kayseri. Boron levels in tap water from cities of the Aegean, Eastern, and Central Anatolian Regions were higher than those from cities of the Marmara, Black Sea, South East, and Mediterranean Regions. The overall mean value was around 0.2 mg/L, lower than the limit levels given by the WHO and the European Union, and also the limit level established by Turkish regulations. In some cities, these limit values were exceeded, generally in the tap water of cities where the drinking water based on groundwater or of those located in the vicinity of hot springs, volcanic areas, or boron production regions. This is the most detailed study evaluating boron levels in the drinking water of Turkey. To conclusion, since the boron intake is being mainly with nutrients and drinking water it may effect public health. To know boron levels in drinking waters is also very important for epidemiologic studies and for establishment of database of boron level in drinking waters in Turkey.

Tagetes patula grown in the substrate with 12.5% creosote impregnated used wooden sleepers chips additive is characterized by the most intensive root development and the biggest population of active fungi, therefore it is recommended for further investigation. Number of colonies of fungi in the rhizosphere of investigated plants decreased in many cases by increasing the amount of sleepers chips additive in substrate, however it was greater in the substrates with creosote treated wooden sleepers chips additives (12.5, 25 and 37.5% wooden sleepers chips) than in the pure substrate and various substrates with additives of pure Pinus sylvestris chips.

The impact of acidification on the ostracod species Cypridopsis vidua as a model organism has been studied. To provide the best rearing conditions, a preliminary experiment with different food concentrations was performed. Cypridopsis vidua reached higher survival under the established experimental conditions when reared with 1.5 × 106 cells of Scenedesmus obliquus per ostracod. Two CO2-driven acidification experiments were designed: the first, an acute experiment (96 hours) pH 6.0, 6.5, 7.0 and 8.3 showed that at low pH the survival rate decreased by more than 90%. The second was a chronic experiment (21 days) pH 7.3, 7.8 and 8.3 with a sharp decrease (60%) in reproduction rate and effects on phototactic behaviour at low pH.

In the present study the safety to consumer after the consumption of pome fruits and fruiting vegetables originated from the area of Thessaly, Central Greece was assessed. Objective samplings of 110 samples were conducted in local retail markets in an effort to quantify potential residues of targeted pesticides, previously characterized as endocrine disruptors. For the determination of residues, a QuEChERs-based multiresidue method coupled with liquid and gas chromatographic systems was applied and fully validated in accordance with the European Unions’s requirements in apples and tomatoes in three fortification levels. Acceptable results were obtained for all the validation parameters studied and the limit of quantification of 0.01 mg/kg and limit of detection of 0.0033 mg/kg were achieved. Based on the determined results, the most frequently determined pesticide was chlorpyrifos with a maximum concentration of 0.32 mg/kg in tomato samples. Cypermethrin and dimethoate were also determined in tomatoes and aubergines. The EFSA PRIMo rev.3.1 model was applied for all positive samples and acute risk for consumers was confirmed only in the case of determination of chlorpyrifos in tomatoes.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"1 1","pages":"105 - 123"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77292244","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}

In Nadia, West Bengal, we trace possible means of transfer of As from multiple sources reaching different trophic levels, and associated seasonal variability leading to chronic As uptake. This work considers possible sources-pathways of As transfer through food chain in rural community. Arsenic concentration in groundwater, soil, rice, and vegetable-samples collected detected in different harvest seasons of 2014 and 2016. Arsenic level in shallow groundwater samples ranged from 0.1 to 354 µg/L, with 75% of the sites above the prescribed limit by WHO (10 µg/L) during the boro harvest season. High soil As content (∼20.6 mg/kg), resulted in accumulation of As in food crops. A positive correlation in As conc. with increase over period in all sites indicating gradual As accumulation in topsoil. Unpolished rice samples showed high As content (∼1.75 mg/kg), polishing reduced 80% of As. Among vegetables, the plant family Poaceae with high irrigation requirements and Solanaceae retaining high moisture, have the highest levels of As. Contaminated animal fodder (Poaceae) and turf water for cattle are shown to contaminate milk (0.06 to 0.24 µg/L) and behoves strategies, practices to minimize As exposure.","PeriodicalId":23210,"journal":{"name":"Toxicological & Environmental Chemistry","volume":"2012 1","pages":"62 - 77"},"PeriodicalIF":0.0,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87722024","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}
