BACKGROUND In this research, the removal of natural organic matter from aqueous solutions using advanced oxidation processes (UV/H2O2) was evaluated. Therefore, the response surface methodology and Box-Behnken design matrix were employed to design the experiments and to determine the optimal conditions. The effects of various parameters such as initial concentration of H2O2 (100-180 mg/L), pH (...

We investigated the distribution and metabolism of SRR a -tocopherol ( SRR a -Toc), synthetic a -Toc compared with RRR a -Toc, in rats after a single oral administration of 2 mg (20 m Ci) SRR and RRR a -[5-methyl14 C]Toc. In the liver, there was no difference in the recovery of radioactivity until 12 h after administration, and it reached a maximum of 4.4% of the dose after 12 h, but in other t...

The contributions of total organic carbon and nitrogen to elemental cycling in the surface layer of the Sargasso Sea are evaluated using a 5-yr time-series data set (1994}1998). Surface-layer total organic carbon (TOC) and total organic nitrogen (TON) concentrations ranged from 60 to 70 M C and 4 to 5.5 M N seasonally, resulting in a mean C :Nmolar ratio of 14.4$2.2. The highest surface concent...

TOC is the acronym for total organic carbon. The first TOC methods were developed to correlate information obtained from chemical oxygen demand (COD) and biochemical oxygen demand (BOD) tests in drinking and wastewater. Today new government regulations are making TOC analysis a standard test for all industry water types. This paper discusses the principles of operation of common TOC methods and...

The total organic carbon content (TOC) is a crucial indicator for the evaluation of shale gas reservoirs, traditionally estimated by measuring cores, cuttings or sidewall cores in laboratory with source rock evaluation instruments. Limited by the number of rock samples, the experimental results are not continuous and it is impossible to show the whole face of a source rock bed. Continuous high ...

Ž . Ž . Samples for total organic carbon TOC analysis were collected on WOCE Line P15S 08 to 678S along 1708W and from Ž . 538 to 678S along 1708E in the western South Pacific, and on Line I8 58N to 438S along 808r908E in the central Indian Ocean. TOC concentrations in the upper ocean varied greatly between the regions studied. Highest surface TOC Ž . Ž . concentrations 81–85 mM C and 68–73 mM ...

BACKGROUND Despite the increasing popularity of the theory of change (ToC) approach, little is known about the extent to which ToC has been used in the design and evaluation of public health interventions. This review aims to determine how ToCs have been developed and used in the development and evaluation of public health interventions globally. METHODS We searched for papers reporting the u...

Laboratory methods for measuring bioaccumulation of organic contaminants from sediment into aquatic organisms continue to improve, but some aspects are still in need of standardization. From a review of published methods, we noted that the loading density of organisms was determined inconsistently and was primarily based on either sediment volume or total organic carbon (TOC). The rationale mai...
