Chemistry and Ecology (CHEM ECOL)

Publisher: Taylor & Francis

Journal description

Chemistry and Ecology publishes original papers, short communications and occasional review articles on the relationship between chemistry and ecological processes. The journal will reflect the fact that chemical form and state, as well as other basic properties, are critical in their influence on biological systems and that understanding of the routes and dynamics of the transfer of materials through atmospheric, terrestrial and aquatic systems, and the associated effects, calls for an integrated treatment. Chemistry and Ecology will help to promote the ecological assessment of changing chemical environment and in the development of a better understanding of ecological functions. Chemistry and Ecology encourages multi-disciplinary approaches dealing with: 1. Environmental pollution: distribution, fate and ecological implications of pollutants including nutrients and key elements, in the atmospheric, soil and aquatic environments. 2. Ecotoxicology: responses to toxic agents at community, species, tissue, cellular and sub-cellular level, including aspects of uptake, metabolism and excretion of toxicants. 3. Environmental bioremediation and biotechnology: laboratory and field research on the identification, evaluation and use of biological/biotechnological items and supporting physical treatments for the restoration of contaminated soil and aquatic environments; laboratory and field research on microbial, plant or animal fouling and its monitoring and their treatment. 4. Biogeochemical cycles: biogeochemical cycles in terrestrial and aquatic ecosystems with special emphasis on the potential effects of pollutants.

    ABSTRACT: Endophytic fungi, being closely associated with their host plants, are an important part of the ecosystem and food web. In modern agriculture, pesticides are widely used. The impact of pesticides on the endophytic fungal community of crops remains poorly understood. In this paper, Chinese cabbage Brassica chinensis, a popular leafy vegetable consumed worldwide, was selected for evaluating the potential effects of a pesticide, deltamethrin, on the endophytic fungal community. By culture method, 195 endophytic fungal strains classified into 39 taxa and 186 strains classified into 30 taxa, respectively, were isolated from the pesticide-treated and untreated B. chinensis samples. Sirodesmium spp. were the predominant endophytic fungi from both samples. The colonisation rates of endophytic fungi of the treated and the untreated samples were not significantly different, as determined by one-way analysis of variance (p > .05). The Shannon diversity indexes (H′) were close, being 2.216 and 2.152, respectively. However, the endophyte compositions of the treated and the untreated samples were significantly different (p < .01) by the canonical correspondence analysis. The similarity coefficient of the endophyte assembles was only 29.0%. Our results indicate that the application of deltamethrin lead to the change of the endophytic fungal assemble in B. chinensis.

    ABSTRACT: Heavy metals are common marine and soil pollutants that are mainly the result of industrial activity, and are a threat to the environment and human health. In this study, 1H nuclear magnetic resonance (NMR)-based metabolomics was applied to adult Danio rerio to monitor the metabolic change as a response to ZnCl2 and CdCl2 exposure at different concentrations for 72 h. NMR spectroscopy was used to identify and quantify the metabolites extracted from D. rerio. The metabolite profiles of the control and heavy metal exposed group were classified by partial least squares – discriminant analysis (PLS-DA) analysis, and potential contaminant-specific biomarkers were suggested. For the ZnCl2-exposed zebrafish, the levels of ATP, aspartate and NAD+ were increased, whereas the levels of formate, inosine, hypoxanthine and succinate decreased. In addition, the CdCl2-exposed zebrafish showed an increase in the levels of ATP and formate and a decrease in the levels of glutamate, inosine and glutathione. Overall, Zn and Cd may lead to neurotoxicity, disturbances in the energy metabolism and oxidative stress. Our finding demonstrated that the application of NMR-based metabolomics might be useful for detecting the toxicity caused by sub-lethal concentrations of heavy metal contaminants in the environment.

    ABSTRACT: Distribution (seasonal and spatial) of aliphatic and polycyclic aromatic hydrocarbons (PAHs) in surface sediments of the Chitrapuzha River, Cochin, India, was investigated using gas chromatography. Significantly high concentrations prevailed during the pre-monsoon season with the industrial zones of the river appearing to be hot spots with particularly elevated levels of the hydrocarbons. AHCs ranged between 7754 and 41,173 ng/g with an average of 25,256 ng/g, while total PAHs varied from 5046 to 33,087 ng/g. n-Alkane indices and PAH diagnostic ratios point to petroleum contamination in the sediments. The significance of PAHs in the sediments was explored using universally accepted interpretation tools. Observed levels of PAHs in sediments of Chitrapuzha are likely to cause adverse effects on biota.

    ABSTRACT: This study investigates the partitioning of metals in surface sediments from the Dan River drainage basin, the source of drinking water for the South to North Water Transfer Project, China, to determine their bioavailability and associated levels of risk. Sediment samples were collected from 99 sites along the Dan River, and the concentration of each element fraction was determined using sequential extraction and inductively coupled plasma-mass spectrometry. The residual fraction was the major phase for most metals sampled. Among the non-residual fractions, greater proportions of Zn, Mn and Cd were transported in in the available phase, whereas Ba, Sb, Pb and As were mainly found in the reducible phase. The oxidisable phase was important for the transport of Ni, Co, Cr and Cu in sediments. This analysis of sediments from the Dan River basin indicates a very high risk of pollution from Cd, Co, Mn, Sb and Zn. Combined with the sediments with extremely high concentrations, the Dan, Laoguan and Yinhua rivers, which have been affected by ore-mining activities, pose a very high risk to the surrounding areas and should be the subject of future studies.

    ABSTRACT: An artificial soil method was applied to study the effects of perfluorooctane sulphonate (PFOS) and perfluorooctanoic acid (PFOA) on earthworms (Eisenia fetida). Survival, growth inhibition and damage to DNA of earthworms were detected after 14 d acute exposure. The 14 d-LC50 of PFOS and PFOA was 478.0 mg·kg−1 dw and 759.6 mg·kg−1 dw, respectively, indicating that they were of low toxicity. Both PFOS and PFOA could significantly inhibit the growth of earthworms after 14 d exposure, and growth inhibition rates increased with the greater concentrations of PFOS or PFOA, showing a dose–response relationship (PFOS: r = 0.951, P < .01; PFOA: r = 0.962, P < .01). PFOS or PFOA were shown to damage earthworm coelomocytes DNA, the indicators of treatments exposed to PFOS or PFOA, tail length (TL), comet length (CL), head DNA content (HD) and olive tail moment (OTM) were significantly different (P < .05) from the control treatments, and the indicators and concentration of PFOS or PFOA had a strong dose–response relationship. 14 d-LC50 of PFOS was lower than that of PFOA, the growth inhibition rate of earthworm exposed to PFOS was higher than that exposed to PFOA at the same concentration level, and the median values of TL, CL and OTM in PFOS treatments were also higher than those in PFOA treatments. In conclusion, both these fluorine compounds were moderately toxic to earthworms, but the PFOS effect was greater than that of PFOA.

    ABSTRACT: Flooding of wetland or agricultural soils can result in substantial alteration of the pore water trace metal profiles and potentially also influence the bioavailability of other trace elements adsorbed to the insoluble oxides. Experimental microcosms were used to quantify the impact of rice (Oryza sativa) plants across an entire growing cycle on the concentrations of Mn2+ and Fe2+ in two soil types (red sodosol and grey vertosol). Two water management treatments were included: a standard flooded treatment and a saturated treatment (−3 kPa). Soil pore water profiles were established from samples collected at four sampling depths (2.5, 7.5, 15 and 25 cm) on 50 occasions. Fe2+ and Mn2+ concentrations were higher in flooded soil than in saturated soil and greatest at a depth of 7.5 cm. The presence of rice plants increased Mn2+ concentrations in flooded soils, but tended to decrease Mn2+ concentrations in saturated soils. The influence of rice plants on Fe2+ concentrations was greatest at a depth of 7.5 cm. Changes in soil pore water Fe2+ and Mn2+ concentrations due to the presence of rice plants were correlated with flowering and reproduction.

    ABSTRACT: There is contradiction about Vetiveria zizanioides (L.) Nash as arsenic hyperaccumulator. The suitability of V. zizanioides plant for Arsenic (As) tolerance and accumulation in the plant biomass has been investigated for phytoremediation application. Plants were treated with 0, 25, 50, 75, 100 and 150 mg L−1 As levels in Hoagland nutrient solution. Arsenic accumulation in shoot and root biomass was determined after 14 days. Metal extraction competency from matrix and accumulation in the above ground plant part revealed that V. zizanioides accumulate As at a low level. Inefficiency of As accumulation by this plant relates to the absence of arsenate reductase activity, transcript of the arsC gene which is crucial for As detoxification. Though, the V. zizanioides system sustains low-level As stress, it is not suitable for As phytoextraction.

    ABSTRACT: In this study, mangrove seedlings (Kandelia obovata (S. L.)) were cultivated in rhizo-boxes, which contain sediments collected from natural mangrove forest and modified with different rates of sulphate and phosphate. The fraction distributions of Zn, Cd, Cu, Ni and Pb in rhizosphere and non-rhizosphere sediments were studied by using a sequential extraction method. Metal concentrations in plant tissues and iron plaque on root surface were also determined to reveal migration variation of heavy metals in the plant-sediment system. The results showed that the activities of K. obovata roots enhance the reducible metals while reducing acid-extractable and oxidisable metals; sulphur amendment benefits the combination of metal ions with S2– and therefore reduces the bioavailability of metal pollutants; addition of sulphur also improves the content of iron plaque on the root surface, which plays an important role in metal accumulation by K. obovata root tissue; the addition of sulphur markedly reduces the concentration of Cd in roots, but significantly enhanced the concentrations of Cu, Zn, Ni and Pb in roots. The results indicate that sulphur and phosphorus content in mangrove sediment, and the growth of mangrove plant can significantly influence the migration of heavy metals in the mangrove wetland ecosystem.

    ABSTRACT: The growing awareness of environmental and health problems due to increased use of pesticides has led to the implementation of various monitoring programmes. Thus, to monitor residues in crops, dissipation studies were conducted of atrazine in the soil of winter maize in field conditions under the subtropical climatic zone of the Tarai region of India. A maize field was treated with atrazine at 2.0 and 4.0 kg a.i. ha−1 as pre-emergent herbicide. The degradation pattern of atrazine indicated correspondence to monophasic first-order kinetics in soils. The persistence of atrazine in soil was more in higher rate (135 days) compared with lower (100 days) application rate. The half-life values calculated to be 16.4 and 20.8 days at lower and higher application rate, respectively. Detector response was linear within 0.01–1.0 μg mL−1 concentration range at per cent relative standard deviation 2.07%. The instrument limit of detection was 1 ng mL−1 and limit of quantification for soil, straw and cobs 0.005, 0.007 and 0.006 μg g−1, respectively. The average recoveries of atrazine from soil, cobs and straw samples were found between 86.8–90.0%, 88.0–91.6% and 93.2–95.6%, respectively. At both the application rates, no residues have been observed in soil, maize cobs (seeds) and straw at the time of harvest.
