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: There is a recognised need to integrate multiple toxicity data deriving from battery bioassays into an easily understandable and single value, which may facilitate the decision-making process related to the management of contaminated sediments. In this study, two integration results systems were applied and compared: toxicity classification system (TCS) and Toxicity Test Battery integrated Index (TBI). The quality of sediments of the Taranto seas (Mar Grande and Mar Piccolo) was assessed by a battery of five test species representing different trophic levels (Dunaliella tertiolecta, Tigriopus fulvus, Corophium insidiosum, Mytilus galloprovincialis, and Anphibalanus amphitrite) and performed on three exposure phases (elutriate, porewater, and whole sediment). The integration of biological tests results with TBI showed that stations located in Mar Grande and one station in Mar Piccolo were in the high ecotoxicological risk level, according to the results obtained with TCS. The comparison of results deriving from two evaluation systems showed similarity in the ecotoxicological risk level. Only in one case there was a lack of concordance between two indices giving opposite judgments. The present study demonstrates that the use of one of the two indices can be useful to estimate and to rank hazard level for sediments.

    ABSTRACT: The immobilisation of heavy metals in the soil of a 25-year-old active firing range using durian (Durio zibethinus L.) tree sawdust (DTS), coconut coir (CC) and oil palm empty fruit bunch (EFB) was investigated. The immobilisation effects were evaluated in terms of metal accumulation in water spinach (Ipomoea aquatica) and soil metal bioavailability. A pot experiment was conducted by amending the firing range soil with DTS, CC and EFB at application rates of 0%, 1% and 3% (w/w), respectively. All amendments increased the biomass yield and reduced the uptake of heavy metals in the plant tissue. Zn had the highest values of Bioconcentration Factor (BCF: 0.301–0.865) and Translocation Factor (TF: 1.056–1.883). Pb was the least-accumulated and transported metal in the plant tissues, with the BCF and TF values of 0.019–0.048 and 0.038–0.116, respectively. The bioavailable fraction of heavy metals in the firing range soil decreased following the application of the three agricultural wastes studied. DTS, CC and EFB did not cause toxicity symptoms in the water spinach over the pot experiment. Therefore, DTS, CC and EFB are considered promising immobilising agents for the remediation of metal-contaminated land.

    ABSTRACT: A bioflocculant-producing strain named MY6-2 was isolated from a mixed activated sludge by a nitrogen-free medium. Based on 16S rDNA sequence, biochemical and morphological characteristics, the strain MY6-2 was identified as Bacillus mucilaginosus. The chemical analysis indicated that the flocculant MY6-2 was mainly composed of extracellular polysaccharide. The result of the composition of the medium showed that MY6-2 was able to generate bioflocculant in a nutrient-poor medium that consisted of 5 g L−1 sucrose and no nitrogen source. Response surface methodology (RSM) was used to optimise the fermentation condition of MY6-2 for maximum flocculating activity by using central composite design (CCD). Based on the result, the optimum conditions were as follows: 100 mL of broth in a 250 mL Erlenmeyer flask, initial pH 8.0 and inoculum concentration 10%, respectively. The highest flocculating rate of 90% was achieved under these conditions by adding 0.5 mL fermentation supernatant to 95 mL of Kaolin suspension.

    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: In 1970, a programme of land recuperation started in Venezuelan savannas, strongly affected by the seasonality of precipitation; therefore, a network of dykes has been built to alleviate the floods and retain water throughout the dry period. Under the dyked system, the environment has been altered, allowing a change in the herbaceous vegetation towards aquatic species and an increase in primary production. It is assumed that a considerable quantity of nutrients is lost from the ecosystem through the floodgates, a situation that could be worsened with the climate change. This contribution describes the atmospheric input and total output in stream run-off of phosphorous (P) in a flooded savanna. Internal pools of the biogeochemical cycle of P associated with terrestrial compartments are described. In the flooded savanna, a large amount of P is immobilised (29.6kg ha−1) in their above ground biomass by grasses, and in soil microbial biomass. The P budget was nearly balanced, as measured losses were cancelled out by the inputs in rainfall. Soils act as a sink, retaining P coming either from precipitation or from desorption/mineralisation processes. That interruption can be maximised, and losses of P and other nutrients can be minimised with an adequate management of the floodgate.

    ABSTRACT: Ca2+-Mg2+-ATPase is a membrane-bound enzyme and is responsible for regulating cytosolic free calcium. In vitro and in vivo effects of cadmium were studied on Ca2+-Mg2+-ATPase activity in plasma membrane/mitochondrial fraction of Penaeus monodon post larvae. In vitro studies revealed a concentration-dependent decrease in enzyme activity with an IC50 value of 11.02 µM. In vivo experiments were conducted by exposing the post larvae to 1/10th (0.12 ppm) and 1/5th (0.24 ppm) of LC50 values of cadmium for 30 days. Both ATPase activity and metal accumulation were estimated in post larvae exposed to 0.12 and 0.24 ppm of cadmium at different intervals of 24 h, 48 h, 96 h, 10 days and 30 days. ATPase activity showed a gradual decrease in post larvae on exposure to both the sub-lethal concentrations with respect to their controls and the decrease was significant (p <.05) from 96 h onwards in post larvae exposed to 0.24 ppm and 10 days onwards on exposure to 0.12 ppm of cadmium. However, the effect of cadmium was higher in 1/5th than 1/10th sub-lethal concentration and also time-dependent. These enzyme studies were found to correlate with metal accumulation in post larvae at both the exposure concentrations. Disruption of calcium homeostasis might be one of the possible mechanisms of cadmium toxicity in these organisms.

    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.
