The potential sources of 16 PAHs in surface sediments from highly tourism activities of Chalong bay, Phuket province, Thailand were apportioned. Twenty-eight of sediment samples were collected by using van Veen grab Sampler from Chalong bay, Phuket. Quantitative analysis of the 16 PAHs which categorized according to the USEPA was analyzed by Gas Chromatography-Mass Spectrometry (GC/MS). Moreove...

Four van Veen grab replicates where collected to sample macrofauna (organism retained on a 500 micron mesh sieve) at four stations in the Gulf of Nicoya, during October 24, 1997, January 16 and April 30, 1998. This information was used to search for any effects of trawling on the benthic fauna. Two stations where located in a trawled area, and two stations where in a protected area. Diversity (...

This study investigated the importance of variations in environmental factors affecting the abundance patterns of decapods on the southeastern Brazilian coast. Sampling was carried out monthly from January 1998 through December 1999 in Ubatumirim and Mar Virado, Ubatuba region, using a commercial shrimp fishing boat equipped with double-rig nets. Six areas adjacent to rocky shores were chosen. ...

Dietary and clinical surveys carried out in India, Africa and in several countries elsewhere, in Asia and South America, have shown that the diets of large numbers of people are deficient in many essential nutrients such as proteins, vitamins and minerals (Patwardhan, 1952; Autret & Behar, 1954; Gopalan & Ramalingaswami, 1955 ; Brock & Autret, 1952). Protective foods such as milk, eggs, fish an...

In this paper in the March 2009 issue of Leprosy Review van Veen et al. presented an article on evaluating three simplified nerve function impairments (NFI) in leprosy. I have a question and a comment on this study. Question: In this multi-centric study in two countries, the authors decided to recruit at least 50 patients from each centre as samples; thus in 8 centres a total sample population ...

Species composition, distribution, density, biomass, diversity and trophic relationships of the macrobenthic communities in Ubatuba Bay, southeastern Brazilian coast, were investigated seasonally from August 1995 to June 1996. Sampling was carried out at 9 stations of between 4 and 13 m depth and taken in duplicate with a 0.1m2 van Veen grab. Two hundred and five macrofaunal species were identi...

Surface sediment samples from the Arabian Gulf coast of Saudi Arabia were collected by Van Veen grab sampler to identify characteristics, distribution, and levels discriminate between natural anthropogenic sources total extractable organic matter (TEOM). The dried sieved sediments extracted with a dichloromethane/methanol mixture for analysis gas chromatography-mass spectrometry. TEOM included ...

Benthic macroinvertebrates are helpful bio-indicators providing better understanding of modified and perturbed aquatic ecosystems. This study seeks to determine the ecological status diversity macroinvertebrate community in relation environmental variables western Nigerian offshore waters within Gulf Guinea. Macroinvertebrate samples were collected from five (5) sampling stations using a Van-ve...
