Persistent organic pollutants and heavy metals in adipose tissues of patients with uterine leiomyomas and the association of these pollutants with seafood diet, BMI, and age.Email this article to a colleague. Save this article to My Clippings. discuss this article 1 CommentDiscuss or comment on this article.
CONCLUSION: Our studies demonstrated that these persistent organic pollutants and some heavy metals may have correlations with UL, and their accumulation in the body is positively correlated with seafood diet habit, body mass index, and age. In the patient group, higher levels of persistent organic pollutants and some heavy metals were found in visceral fat than in subcutaneous fat confirming the long-held belief that visceral fat is more pernicious and pathogenic than subcutaneous fat. RECOMMENDATIONS AND PERSPECTIVES: It is recommended that women minimize their exposure to environmental pollutants as much as possible whi...

Degradation of phenols in olive oil mill wastewater by biological, enzymatic, and photo-Fenton oxidation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Phenols were removed more efficiently by photo-Fenton treatment than by biological or enzymatic treatments. RECOMMENDATIONS AND PERSPECTIVES: Use of fungi, laccase, or photo-Fenton presents great potential for removing phenols from OOMW. This should be further assessed by increasing the application scale and the reactor configurations effect on the performance, besides a toxicity evaluation of treated wastewater in comparison to raw wastewater.

Phyto/rhizoremediation studies using long-term PCB-contaminated soil.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: In addition to uptake, accumulation and partial metabolisation of PCBs by plants, compounds produced by plants allow survival of microorganisms even in poor soils, serve as carbon and energy source, and can even induce the degradation pathways of different xenobiotics. Thus, the choice of proper plant species is crucial for effective cleaning of different polluted sites. Our study shows how the efficiency of PCB removal is dependent on the plant used. RECOMMENDATIONS AND PERSPECTIVES: The use of plants in biological remediation of different organic xenobiotics proved to be a useful approach. Further improvemen...

Hyperaccumulation of vanadium in the Antarctic polychaete Perkinsiana littoralis as a natural chemical defense against predation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
DISCUSSION: Analyses of trace metals in tissues of P. littoralis confirmed the naturally high bioavailability of cadmium due to upwelling phenomena in the investigated area and revealed extremely high concentrations of vanadium up to 10,000 microg/g, in the branchial crowns; much lower concentrations were measured in the body portions and even less in the Antarctic bivalves and in Mediterranean polychaetes. The subcellular distribution indicated that this metal was associated in branchial crowns with both heavy components and vanadium binding proteins; the latter predominated in body tissues, although with a different patt...

Isotope ratios of lead in Japanese women's hair of the twentieth century.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
DISCUSSION: Isotope ratios as well as Pb concentration in the hair samples of the twentieth century varied to a considerable extent depending on the period of hair cut. The oldest hair samples (1910-1920s) had the highest concentration and the most distinct isotope ratios from those of Japanese domestic Pb indicating serious contamination of proximate environment of people of those days with Pb originated from mines in other regions of the world, probably through the usage of Pb-containing face powder. The concentration and isotope ratios of Pb decreased thereafter indicating less serious contamination of proximate environ...

Suitability of using diffusive gradients in thin films (DGT) to study metal bioavailability in mine tailings: possibilities and constraints.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The use of DGT in mining soils can be a promising tool to study bioavailable metals concentrations in mine tailings but it has to be used carefully under acidic pH. Competition with other cations that are present at very high concentrations may hinder the accumulation of metals by the chelating resins, which should be tested under the conditions of the particular mine tailing.

Oxidative degradation of chlorophenol derivatives promoted by microwaves or power ultrasound: a mechanism investigation.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Oxidative pathways for 2,4-D, 2,4-DCP, and phenol were proposed by a careful monitoring of the reactions and detection of intermediates by GC-MS. RECOMMENDATIONS AND PERSPECTIVES: The understanding of the factors that affect chlorophenols degradation along different pathways may facilitate the optimization of the treatment. Type of energy source (US or MW), power, and frequency to be applied could be designed in function of the operative scenario (amount of pollutant in soil, water, or oils).

A novel method using sedimentary metals and GIS for measuring anthropogenic change in coastal lake environments.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Surficial metal concentrations were highest in the 1975 sediment than in the 2003 samples, with the northern part of Lake Macquarie having much greater metal concentrations than the rest of the lake. Past and future declining sedimentary metal concentrations in the northern part of the lake were expected due to the closure of a nearby Pb-Zn smelter; however, possible increases in Cu in the south of the lake to the year 2020 were surprising. The new method presented in this study can assist estuary managers by providing data on past, present and future conditions, which are essential in making informed decision...

Characteristics of exhaust gas, liquid products, and residues of printed circuit boards using the pyrolysis process.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Brominated and chlorinated compounds-i.e., dichloromethane, trans-1,2 dichloroethylene, cis-1,2 dichloroethylene, 1,1,1-trichloroethane, tetrachloromethane, bromophenol, and bromoform-could be high, up to the several parts per million (ppm) level. Low molecular weight volatile organic compounds (VOCs)-i.e., methanol, acetone, ethyl acetate, acrylonitrile, 1-butene, propene, propane, and n-butane-contributed a large fraction of VOCs. The concentrations of toluene, benzene, xylene, ethylbenzene, and styrene were in the ppm range. PMID: 19806377 [PubMed - as supplied by publisher] (Source: Environmental Scien...

Detection of DNA damage in fish Oreochromis mossambicus induced by co-exposure to phenanthrene and nitrite by ESI-MS/MS.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: MS/MS has proved to be useful in the rapid determination and discrimination of structurally different phenanthrene/derivatives DNA adducts in a complex mixture of fish bile co-exposed to phenanthrene and nitrite. However, the nature of metabolites formed is likely determined by the route of PAH administration, and there is a need to further define the early biochemical events of carcinogenesis in these species.

Seasonal variations of nitrogen and phosphorus retention in an agricultural drainage river in East China.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Riverine nutrient retention capacity varied with environmental conditions. Annual RNRL and RPRL accounted for 30.3-48.3% and 52.5-71.2%, respectively, of total input TN and TP loads in the ChangLe River. Monthly riverine retention ratios were 3.5-88.7% for TN and 20.5-92.6% for TP. Hydrophyte growth and coverage on the river bed is the main cause for seasonal variation in riverine nutrient retention capacity. The total input TN and TP loads were the best indicators of RNRL and RPRL, respectively. RECOMMENDATIONS AND PERSPECTIVES: High riverine nutrient retention capacity during summer due to hydrophytic growth...

Bioremediation of acidic oily sludge-contaminated soil by the novel yeast strain Candida digboiensis TERI ASN6.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: This study establishes the potential of novel yeast strain to bioremediate hydrocarbons at low pH under field conditions. RECOMMENDATIONS AND PERSPECTIVES: Acidic oily sludge is a potential environmental hazard. The components of the oily sludge are toxic and carcinogenic, and the acidity of the sludge further increases this problem. These results establish that the novel yeast strain C. digboiensis was able to degrade hydrocarbons at low pH and can therefore be used for bioremediating soils that have been contaminated by acidic hydrocarbon wastes generated by other methods as well.

Effect-related monitoring: estrogen-like substances in groundwater.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Estrogenically active substances may occur in the groundwater below obsolete landfills, especially those that contain PCBs or waste from gasworks. These substances are not part of analytical programs routinely applied to contaminated sites and may therefore escape detection and assessment. Analyses using the E-screen assay and GC/MS in parallel have shown that the total estrogenic activity found in groundwater samples is to be ascribed to a multitude of individual compounds, some of which cannot be quantified due to lack of standard substances or assessed due to lack of a standardized procedure for determinati...

Salt-driven interactions between Pistacia lentiscus and Salsola inermis.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Soil salinity around Pistacia trees critically affects the growth of S. inermis. Inhibition of S. inermis growth, but not germination, around the evergreen P. lentiscus, stems from the latter's ability to deplete salt from its surroundings. The results indicated that P. lentiscus is able to tolerate and accumulate salt, which we assume contributes to its wide distribution along the Mediterranean coast in Israel. RECOMMENDATIONS AND PERSPECTIVES: While the phytoremediation potential of Salsola spp. has been explored to some extent, this of P. lentiscus has not been tested and proven before. The results suggest ...

A universal method to assess the potential of phosphorus loss from soil to aquatic ecosystems.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The degree of P saturation, which reflects the actual state of P fertilization of soil, can be calculated from the easily accessible parameter WSP. Due to the independence from soil type and land use, the relation is valid for all soils. Values of WSP, which exceed 5 mg P/kg soil, signalize a P saturation between 70% and 80% and thus a high risk of P loss from soil. RECOMMENDATIONS AND PERSPECTIVES: These results reveal a new approach of risk assessment for P loss from soils to surface and ground waters. The consequent application of this method may globally help to save the vital resources of our terrestrial ...

Quantifying phosphorus levels in soils, plants, surface water, and shallow groundwater associated with bahiagrass-based pastures.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Our results indicate that current pasture management systems which include cattle rotation in terms of grazing days and current fertilizer application (inorganic + manures + urine) for bahiagrass pastures in subtropical climates on loamy sand soils offer little potential for negatively impacting the environment. Properly managed livestock operations contribute negligible loads of phosphorus to shallow groundwater and surface water. Overall, there was no buildup of soil total phosphorus in bahiagrass-based pasture. Therefore, results of this study may help to renew the focus on improving inorganic fertilizer ef...

CONCLUSIONS, RECOMMENDATIONS, AND PERSPECTIVES: Despite low mobility of higher chlorinated PCDD/Fs, these contaminants were transferred from the polluted soil to the surroundings and into human tissue. The extent of increased exposure from contaminated sites depends on the PCDD/F source strength of the soil, composition of the pollution, human activities, and dietary patterns of the residents. Impact from the contaminated soil on other exposure media was seen also for areas with low to moderate soil contamination. In the future, not only the levels of PCDD/F soil pollution but also the composition must be considered in ris...

Phytotoxicity tests of solid wastes and contaminated soils in the Czech Republic.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The tests currently used for regulatory purposes in the Czech Republic are phytotoxicity tests of elutriates, using S. alba and D. subspicatus, which have been found insufficiently sensitive to the range of different pollutants present in contaminated soils and/or solid wastes. If only aquatic bioassays are used for the toxicity testing, it is possible that the toxic effects of substances (poorly or totally) insoluble in water might be underestimated. The new proposed system of toxicity classification has proven to be both practical and sensitive. RECOMMENDATIONS AND PERSPECTIVES: This recommended alternative ...

Phytoremediation of contaminated soils and groundwater: lessons from the field.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS AND PERSPECTIVES: It is clear that in spite of a growing public and commercial interest and the success of several pilot studies and field scale applications more fundamental research still is needed to better exploit the metabolic diversity of the plants themselves, but also to better understand the complex interactions between contaminants, soil, plant roots, and microorganisms (bacteria and mycorrhiza) in the rhizosphere. Further, more data are still needed to quantify the underlying economics, as a support for public acceptance and last but not least to convince policy makers and stakeholders (who are not v...

Derivation of motor vehicle tailpipe particle emission factors suitable for modelling urban fleet emissions and air quality assessments.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The comprehensive set of tailpipe particle emission factors presented in this study for different vehicle and road type combinations enable the full size range of particles generated by fleets to be quantified, including ultrafine particles (measured in terms of particle number). These emission factors have particular application for regions which may have a lack of funding to undertake measurements, or insufficient measurement data upon which to derive emission factors for their region. RECOMMENDATIONS AND PERSPECTIVES: In urban areas motor vehicles continue to be a major source of particulate matter pollutio...

Risk assessment of toxins derived from Bacillus thuringiensis-synergism, efficacy, and selectivity.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Risk assessment of genetically engineered plants should put into question the general assumption of a high selectivity and a linear dose-response relationship in the toxicity of Bt proteins. Both selectivity and efficacy can be influenced by synergism, which can provoke unexpected and undesired effects in non-target organisms. PERSPECTIVES: It is suggested that systematic research be promoted on synergism between Bt toxins and potential extrinsic factors that could impact the spectrum of susceptible organisms. This research should become a prerequisite for risk assessment of Bt plants. PMID: 19557450 [PubM...

Estimation of the cancer risk to humans resulting from the presence of cyclophosphamide and ifosfamide in surface water.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: The additional intake of CP and IF due to their emission into surface water and its use without further treatment as drinking water is low compared to intake within a therapy. This approach has shortcomings. It illustrates the current lack of methodology and knowledge for the specific risk assessment of carcinogenic pharmaceuticals in the aquatic environment. IF and CP are directly reacting with the DNA. Therefore, with respect to health effects a safe threshold concentration for these compounds cannot be given. The resulting risk is higher for newborns and children than for adults. Due to the lack of data the...

Effects of shoreline sensitivity on oil spill trajectory modeling of the Lower Mississippi River.Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS: Shoreline re-floatation half-lives have a major impact on simulating the distribution of oil along the shore after a spill, especially in areas with a high variability of shoreline type as in the lower Mississippi River. Assigning the correct re-floatation half-life and retention capacity is only possible when shoreline types have been correctly identified. The maps developed for this study provided an important level of detail and incorporated the change in shoreline type with flow rate, resulting in more detailed trajectory modeling of the study reach. Recommendations and perspectives Shoreline maps should i...

New jet-aeration system using 'Supercavitation'Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSIONS AND DISCUSSION: The observed high oxygen transfer rates cannot be explained by traditional mass transfer mechanisms. It is assumed that a large amount of water being transferred into the gas phase by supercavitation contacting directly oxygen also in the gas phase and thereby overcoming mass transfer hindrances which might be favoured by hydroxyl radicals. With this new aerator, during the first 3 months of test phase, already more than 10,000 Euros had been saved because of the reduced pure oxygen demand.
