TL;DR: It is concluded that a single universal maximum limit on the atrazine application in catchments, as suggested by many regulatory authorities, does not provide adequate protection of the aquatic environment and it is advocated that flexible limits on the application ofatrazine be developed in line with the potential risk of contamination to surface and subsurface water and fragility of the underwater environment.

TL;DR: The study showed that of all the fish parts, fish liver accumulated the highest levels of Cu and Zn, and Manganese presented in the intestine and stomach in the highest concentration.

TL;DR: A strain of Pseudomonas fluorescens, isolated from petroleum hydrocarbon-contaminated soil was examined for its ability to utilize a variety of hydrocarbon substrates and emulsified a number of aliphatic and aromatic hydrocarbons.

TL;DR: The 'Milestones' in the development of BDMs are summarized and explained in detail for a number of bioanalytical tools that can be used to detect these classes of dioxin-like persistent bioaccumulative toxicants (PBTs).

TL;DR: The extent of heavy metal cation contamination in the Shing Mun River has been assessed and contaminated sediments, accumulated over the years on the river bed, could act as secondary sources of pollution to the overlying water column in the river.

TL;DR: Addition of the bacterial consortium in different amendments significantly enhanced the removal of oil from the petroleum sludge from different treatment units.

TL;DR: The present state of knowledge on the effects of Lyngbya majuscula on human health, ecosystems and human populations during a toxic cyanobacterial bloom is reviewed and the potential exists for toxins from Lyng bya majucula affecting ecological health and in particular marine reptiles.

TL;DR: This paper reviews the multitude of data collected on soil Pb concentrations and some methodologies in use around the world reviewed.

TL;DR: The role of plants to assist the treatment of water pollution in man-made wetlands in tropical and temperate climates is illustrated and the potential for environmental education of these wetland systems is considered.

TL;DR: Compared the total and the DTPA-available Cr contents in the soil and the roots and leaves of tree species growing on it with those on the nearby noncontaminated reference site, the potential of mycorrhizae in protecting the host plant against the harmful effect of heavy metals and in phytoremediation of the Cr-polluted soil is discussed.

TL;DR: Anaerobically digested sewage sludges collected from four wastewater treatment plants located in Sha Tin, Tai Po, Yuen Long, and Shek Wu Hui were subjected to chemical characterization and toxicity testing to provide preliminary assessment of their suitability for land application.

TL;DR: In general, the maximum CO, SO2, NOx, and TSP values occurred during the winter with minimum values occurring during the summer, which can be attributed to a combination of meteorological conditions and photochemical activity in the region.

TL;DR: The diethylenetetramine pentaacetic acid (DTPA)-extractable Pb, Zn, Cu, and Cd concentrations of acidified tailings surface were significantly higher than those of nonacidify tailings, which revealed that acidification enhanced the mobility of heavy metals in the tailings.

TL;DR: The findings obtained suggest that the mercury pollution in the Amazon should be crucially observed for head hair mercury level and health in a much broader region.

TL;DR: In this paper, the nocturnal excretion of catecholamines in urine was studied in 30-45-year-old women whose bedroom and/or living room were facing streets of varying traffic volume.

TL;DR: In this article, the airway irritation of a reaction mixture of R-(+)-limonene and ozone was evaluated by a mouse bioassay in which sensory irritation, bronchoconstriction and pulmonary irritation were measured.

TL;DR: Modified PMt can be recycled, and it is a potential substance for adsorption of environmental pollutants, and using modified PMt with surfactant can improve adsorbing capacity greatly.

TL;DR: The output and input (O/I) ratio of the PAHs from the incineration trials of plastic wastes, thePAHs involved in incineration of three plastic wastes were almost entirely destroyed; and a low residual amount between 0.00018 and 0.00032 remained in the emission.

TL;DR: The results indicate that all the milk samples were contaminated with dichlorodiphenyltrichloroethane (DDT and its metabolites) and isomers of hexachlorocyclohexane (HCH; alpha, beta, and gamma), heptachlor and its epoxide, and aldrin.

TL;DR: There is evidence of contamination (especially with Zn and Pb) in sediments from sites affected by colliery spoil and from the Wear estuary, where the control site and the Tees estuary appear to be the least affected.

TL;DR: The diagnosis of the biopotency of these pollutants in technical processes like thermally treated waste, waste water treatment, landfill leachate treatment, commercial PCB-mixtures, the release into the environment and the final intake into wildlife and humans will be reviewed.

TL;DR: Water quality and river sediments of Dongjiang have been mildly contaminated by heavy metals and organic chemicals, such as copper, lead, PCBs, PAHs and HCHs, which merit concern.

TL;DR: Comparing metal concentrations in algae among the studied sampling stations clearly indicates that the degree of accumulation depends not only on human activities but also on the geology of the specific area, and it is important to take account of a region's geology before attempting to interpret the data.

TL;DR: Although the external nutrient loading has been reduced, nutrients could gradually be released back into the water column from the contaminated sediments and delay improvement of the water quality.

TL;DR: It is indicated that limestone can be used as an alternative to replace activated carbon in the removal process of heavy metal removal from wastewater by batch study and filtration technique through low-cost coarse media.

TL;DR: This paper offers a decision conferencing approach to sustainable development planning based on a multicriteria model and the integrated model is presented and applied to austainable development planning exercise in a third world country.

TL;DR: Samples of sea urchins (Paracentrotus lividus), holothurians (Holothuria polii), green algae (Ulva lactuca, Codium vermilara and Enteromorpha prolifera ) and sediments were collected from different coastal zones of the South Adriatic Sea (Italy) as discussed by the authors.

TL;DR: Variations in resistance levels were observed when soil before and after spread ofAnimal waste was compared, indicating an effect from spread of animal waste on selection of resistance among soil bacteria.

TL;DR: Coal ash obtained by coal combustion in the "Nikola Tesla A" power plant in Obrenovac, near Belgrade, Yugoslavia, is mixed with water of the Sava river and transported to the dump, assessing pollution caused by leaching of some minor and major elements during ash transport through the pipeline.

TL;DR: The results showed that wetland vegetation did not play an important role in oxygen demand removal but were capable of removing about 22% and 26% of the nitrogen input in the FWS and SF wetland units, respectively.
