TL;DR: PBDEs are structurally similar to PCBs and DDT and, therefore, their chemical properties, persistence and distribution in the environment follow similar patterns.

TL;DR: It is concluded that dust generated from sources within the house itself can contribute significantly to exposures to certain elements, such as lead, cadmium, antimony and mercury.

TL;DR: In this article, the authors used a high flow gravimetric personal sampling system to assess personal exposure to PM2.5 in transport microenvironments in central London, UK, where exposure levels were assessed along three fixed routes at peak and off-peak times of the day.

TL;DR: Capping seems to be a promising approach for a low-cost remediation of contaminated anoxic sediment of the Mulde reservoir, which confirmed the necessity of sediment remediation in the reservoir.

TL;DR: It appears that the main cause of high influx is sediment loads mobilized from intensively managed land, and fundamental changes to the management of agricultural land is required if fish habitats are to be improved and degraded streams are allowed to re-naturalize.

TL;DR: The local pedo-geochemical background Cd and Zn content of the upper wooded part of the Dornach site proved to be clearly higher than that which would be encountered in most soils of Switzerland and France.

TL;DR: Some bio-physical parameters, such as chlorophyll a concentration, Secchi disk depth and water surface temperature were mapped in the sub-alpine Lake Iseo (Italy) using Landsat Thematic Mapper data acquired on the 7 March 1997 in order to adequately investigate the water-leaving radiance.

TL;DR: Emission profiles from field burning and charbroil cooking specific to the border area show that a majority of emissions are comprised of carbon, with high organic to total carbon ratios, which indicate different vehicle fleets in border cities.

TL;DR: It is concluded that shrimp farmers should reduce the use of chemicals and biological products because of the risks to the environment, human health and to production, and also, because many chemicals and Biological products used in pond management have not been scientifically shown to have a positive effect on production.

TL;DR: This methodology enables the development of multi-temporal algorithms for estimating seston dry weight concentration in lakes from remotely sensed data; thus satellite data can now become an independent measurement tool for water management authorities.

TL;DR: It was found that peat had a strong influence on CEC, on buffer capacity and on Cu and Cr retention, whereas kaolinite's contribution to the CEC was minor and arsenite was found in significant proportions, indicating some reduction of arsenate to arsenite occurred since the original species in CCA is As(V).

TL;DR: The investigations clearly indicate the deposition of anthropogenic pollutant inputs, not only in the past, but also today, in agricultural fields in the Leipzig-Halle region.

TL;DR: The results of this study showed that the mean concentrations of CO2 at restaurants with gas stoves for food cooking in dining areas exceeded the range from 40 to 60% indoor CO2 concentrations at restaurants without gasStoves in dining area.

TL;DR: The results indicate that the absorption of SO2 is close to completely gas-film controlled where the NaOH concentration is greater than 0.1 M or the KMnO4/NaOH solutions, and the existence of O2 has no significant effect on the absorption rate of So2.

TL;DR: It is shown that the prevailing neutral or slightly alkaline conditions of the rivers ensure that metals are mainly associated with sediment, but elevated metal levels in bottom living larvae collected from contaminated sites suggest that these sediment bound metals are readily bioavailable.

TL;DR: In the most humic lake, the empirical algorithms tested were suitable only for the interpretation of total suspended solids and turbidity, and the use of apparent reflectance instead of radiance improved the estimation of water quality in the case of total suspend solidsand turbidity.

TL;DR: Removal of waste, natural leaching and biological activity, in time, led to an effective decrease in electrical conductivity and phenolic compounds, although residual levels can be important even 2 years later.

TL;DR: Variation of antioxidant enzymes, superoxide dismutase and glutathione S-transferases and the effect of heavy metals and selenium exposure on these enzymes were investigated in the livers of Iberian endemic minnows captured in a copper mining area.

TL;DR: Strong positive correlations were found between concentrations of Co in water and in plants and between Zn in sediments and plants, indicating the potential of plants for pollution monitoring for this metal.

TL;DR: A health risk assessment of platinum (Pt) emitted from automotive catalytic converters is presented and a conservative no-effect level (NOEL) of 1.5 ng/m3 can be derived for the sensitizing effect of halogenated Pt salts.

TL;DR: Calculation for daily Cd intake via rice, taking advantage of the present findings on Cd contents in rice and wheat together with administrative area-specific daily consumptions of rice andWheat showed that Cd via rice is much more than Cdvia wheat and that CD via Rice is highest in an area alongside the sea of Japan among the whole country, the observation being in agreement with the results from a previous food duplicate-based field survey.

TL;DR: The poor correlation between the Hg concentration in the biomonitors to classic clinical signs of chronic Hg intoxication may be explained by several factors: Hg in blood, urine and hair do not adequately monitor the HG burden of the target tissues, especially the brain.

TL;DR: Stream water temperature data from the Girnock burn, a 30-km2 catchment in Scotland were examined for systematic variation across 30 years of record and suggest that there has been no change in mean annual temperature with time, but at a seasonal level there is some indication of an increase in mean daily maximum temperatures during the winter and spring seasons.

TL;DR: The results show that the band combination to be included in the ENVISAT MERIS instrument enables the interpretation of water quality, including chlorophyll a concentration using semi-empirical algorithms both for lakes and coastal waters.

TL;DR: In this article, the average range of concentrations for toxic trace elements in placenta based on wet weight are found to be: cadmium 1-6 ng/g, total mercury 2-13 ng /g, methyl mercury 1-14 microg/g; and lead 5-60 ng / g.

TL;DR: Airborne organic material attached to the leaves can result in high values of these elements without any pollution source and can be used as an indicator of minerogenic dust.

TL;DR: Considering the bioavailability of particle-bound PAHs still remains unknown, the health risks obtained from this study could be overestimated and thus require further investigation.

TL;DR: It is of course not possible to predict the indoor radon concentration of single houses from these maps, because construction type and structural fabric of houses are essentially governing the extent to which subsoil radon potential affects the indoor concentration.

TL;DR: The results suggest that despite the establishment of fast growing grass, P concentrations would not be mitigated in the short-term, due to the large contribution of P in subsurface pathways.

TL;DR: The Pt content was usually high in airborne samples when the Pb, Ce, Zr and Hf content was also high, thus confirming that the source of these pollutants is from traffic.
