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: 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.

    ABSTRACT: Microbial processes, particularly enzyme activities, play crucial functional roles in soil ecology, hence serving as sensitive indicators of soil quality. We assessed the temporal dynamics of microbial biomass and selected soil enzymes (β-d-glucosidase, cellobiohydrolase, polyphenol oxidase, urease, glycine-aminopeptidase and alkaline phosphatase) during wheat cultivation, under four different tillage practices in the rice–wheat system. The four practices involved conventional tilling of soil before cultivating each crop (CTR-CTW); no tilling before cultivating rice but conventional tillage before wheat (NTR-CTW); conventional tilling before cultivating rice but no tilling before wheat (CTR-NTW) and no tilling before cultivation of each crop (NTR-NTW). Microbial biomass and activities of hydrolytic enzymes increased under NTR-NTW followed by CTR-NTW and NTR-CTW with respect to the conventional practice CTR-CTW, thus reflecting improvement in microbial activities with reduced tillage frequency. Enzyme activities generally depended on soil moisture and temperature, but nature of relationships varied among different practices. Nutrient demand appeared to be the strongest driver of alkaline phosphatase and urease, and soil temperature for glycine-aminopeptidase. Under CTR-CTW, activities of most of the extracellular enzymes were related with β-d-glucosidase or urease, but such relations altered under rest of the practices. The study showed that extracellular soil enzymes respond sensitively to tillage practices as well as environmental variables, particularly soil temperature and moisture and hence can serve as a sensitive indicator of changes in soil processes. Considering improvement in microbial biomass and enzymatic activities as indicators of better soil quality, adoption of no tillage apparently improved soil quality. Still, more number of field studies are required under tillage managements to explore the relationships between different enzyme activities and environmental factors.

    ABSTRACT: The structure and composition of the organic matter in landfilled refuse might have an influence on the migration and transformation of dibutyl phthalate (DBP). Humic acid (HA) and humin (HU) were separated from aged-refuse to determine the influences of different organic fractions in the refuse on the sorption and bioavailability of DBP. The sorption kinetics and isotherms for the sorption of DBP to HA, HU, and whole refuse were determined. The results showed that the sorption constants (K) and nonlinearities decreased in the order HU > whole refuse > HA. The HA had lower K values than did the other refuse fractions, and it retarded the biodegradation of DBP over a short degradation period (48 h). Increasing the amount of HA present caused the amount of DBP that was biodegraded to decrease significantly, 81.3% of the DBP sorbed to HA being degraded in the original experiments after 48 h but 21.8% of the DBP being degraded when three times as much HA was used. Similar results were not observed when the amount of HU used was changed. These findings suggest that HA plays an important role in the biodegradation of DBP adsorbed by refuse.

    ABSTRACT: This paper reports impacts of urban pollution on the biochemical and morphological characteristics of Arjuna (Terminalia arjuna) in particular the effects of urban industrial dustfall deposition on its foliar surface at a residential site (Jawaharlal Nehru University, JNU) and an industrial site (Sahibabad, SB) in Delhi region. Atmospheric dustfall fluxes were estimated for major anions and cations. Morphological analysis of foliar samples was carried out by using the scanning electron microscope. Biochemical parameters, namely chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, total soluble sugar, proline amino acid and ascorbic acid were also analysed in foliar samples. Results showed that the dustfall fluxes of () at the industrial site were almost three times higher than that of the residential site. This can be attributed to the emissions of industrial activities and diesel-driven vehicular traffic in the area. It was observed that these elevated fluxes of and had significant impacts on the biochemical constituents of the plant and foliar morphology. Concentrations of chlorophyll and carotenoids were recorded decreasing with increasing dustfall fluxes of (), whereas proline and ascorbic acid were found to be increasing with the increase in the dustfall fluxes of () indicating the effect of pollution stress. The study showed that the deposition of dustfall was responsible for damage to stomata and leaf surface morphology, more significantly at the industrial site.

    ABSTRACT: Antifouling agents, used to prevent biofouling, need to be assessed for their impacts on marine organisms and environment before the application. Diatoms are one of the main components of fouling biofilms, which play important roles in the formation of biofouling. Particularly, diatoms are also the important ingredients of primary production and present interest as ecotoxicological models in marine environment. In this study, two benthic diatoms Nitzschia closterium f. minutissima and Navicula climacospheniae, widely distributed in fouling biofilm, were used as models for screening the activities of potential antifoulants. Nine indole derivatives were tested and CuSO4 was used as a reference. Indole derivatives showed significant anti-algal activities and the EC50 values of most indole derivatives were lower than that of CuSO4. Halogen substituent enhanced the anti-algal activities of compounds, and the most efficient compounds for N. closterium f. minutissima were gramine and 7-chloroindole with the EC50 values of 1.94 and 2.1 mg/L, while for N. climacospheniae, 7-chloroindole and 6-bromoindole were the most efficient and the EC50 values were 3.91 and 4.25 mg/L, respectively. In conclusion, indole derivatives would be one of the promising candidates as antifoulants and our results strengthened the need to perform antifouling activity assays and environment-friendly evaluations.

    ABSTRACT: A facultative bacterial strain isolated from municipal solid waste (MSW) obtained from a simulated landfill bioreactor was found to have the ability to use dibutyl phthalate (DBP) as its sole source of carbon and energy. Based on its morphology, physiochemical characteristics, and 16S rDNA sequence, the strain was identified as Enterobacter sp. T1. Evaluation of the degradation of DBP in refuse collected during the initial, acidic, and methanogenic phases of landfill before and after inoculation with Enterobacter sp. T1 revealed that the degradation fits first-order kinetic models for refuse from all phases. The removal rate of DBP in the refuse of the methanogenic phase increased from 59.3% to 74.5% when Enterobacter T1 was added. The half-life of DBP in refuse from the methanogenic phase that was inoculated with Enterobacter T1 decreased by 36.7% relative to uninoculated samples, and the intermediate products monobutyl phthalate (MBP) and phthalic acid were detected in all samples. These results provide new evidence for the potential of applying Enterobacter sp. for phthalic acid ester-polluted area remediation.

    ABSTRACT: Nutrient chemistry was studied in three mountainous rivers (Mandovi, Zuari and Netravati), across western peninsular India (WPI) during south-west monsoon (SWM), post-monsoon and pre-monsoon seasons of year 2011–2012. Nutrients in rainwater were dominated by dissolved inorganic nitrogen (DIN) and urea, dependent upon industrial emissions and the rainfall location. Nutrients in river water were enriched with DIN and Si(OH)4 as compared with during the SWM season. During pre-monsoon, the river water was enriched with dissolved organic nitrogen (DON), whereas enrichment of a particular nutrient species was not consistent during the post-monsoon season in all three studied river systems. Nutrients exports to the estuarine water were dependent upon the geomorphological feature of river catchment and on prevalent anthropogenic activities. The significant observed contribution of DON to total dissolved nitrogen in Mandovi (62%), Zuari (83%) and Netravati (69%) is important, in view of alterations in biogeochemical processes of adjacent Arabian Sea. Furthermore, the yield of nutrient such as was found to be a function of runoff per catchment area in studied river systems, is comparable with other tropical rivers of world, which highlights the importance of mountainous rivers along WPI in their contribution to the Global riverine nutrient flux.

    ABSTRACT: Tributyltin (TBT), a ubiquitous marine environmental contaminant, has been reported to affect functioning of the central nervous system. However, the mechanism of its neurotoxicity remains unknown. The effects of TBT exposure on the Sebastiscus marmoratus were investigated using a suppression subtractive hybridisation (SSH) combined with mirror orientation selection (MOS) method. A total of 50 candidate clones from SSH libraries were picked for sequencing and homology searching. The results showed that 23 unique differentially expressed genes were obtained, including 11 up-regulated and 12 down-regulated fragments. The functions with which they are associated include energy-related metabolism, polypeptide translation and location, mitosis and cell proliferation. Expression of 11 candidate genes was analysed in brain by real-time fluorescent quantitative PCR. The present study provided a basis for investigating the response of fish to TBT exposure and allowed the characterisation of new potential neurotoxic biomarkers of TBT contamination in seawater.

    ABSTRACT: The adsorption behaviour of Basic Red 12, Acid Orange 7 and Acid Blue 1 on zinc oxide nanoparticles (ZNP) has been investigated to understand the physicochemical process involved and to explore the possible use of nanoparticles in the treatment and management of textile waste matter. The dye removal capacity of ZNP towards Basic Red 12, Acid Orange 7 and Acid Blue 1 was found to be 15.64, 6.78 and 6.38 mg g−1, respectively. The adsorption process was pH dependent and optimum pH values of 9.0, 2.0 and 4.0 were obtained for Basic Red 12, Acid Orange 7 and Acid Blue 1, respectively. Equilibrium was established after 1.0 h for all dyes. Langmuir, Freundlich and Temkin isotherm models were applied to the system. The adsorbent ZNP was characterised using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET) and Fourier transform infrared (FTIR) techniques. SEM analysis revealed the noticeable nanoporous morphology of the material. The results of FTIR spectroscopy showed that the process is driven by an electrostatic complexation mechanism. XRD studies revealed the nanocrystalline structure of ZNP. BET surface area measurement suggested a high pore volume and large surface area for the adsorbent. The kinetic measurements suggested pseudo-second-order kinetic processes with high regression coefficients and smaller standard error of estimate values and lower residual sum of squares. The thermodynamic measurements suggested that all processes were exothermic and accompanied by negative values for Δ G 0, Δ S 0 and Δ H 0.
