Small-scale Freshwater Toxicity Investigations: Volume 2

Book Description

While toxicity testing procedures and hazard assessment approaches have been published in past decades, many are wanting in detail for users to fully understand or reproduce successfully. Small-scale Freshwater Toxicity Investigations (Volumes 1 and 2) responds to this need by providing comprehensive information on biological testing which is normally scattered and difficult to find. In Volume 2, 11 chapters on hazard assessment schemes are described in great detail by way of a homogeneous structure that all contributors had to follow. These comprehensive texts allow readers to know the different approaches/strategies, based on applying batteries of bioassays, that are being used internationally to assess the toxic potential of complex environmental media (e.g., effluents, sediments) impacted by chemical contamination stemming from human activities. Academia (students, professors), government (environmental managers, scientists, regulators) and consulting professionals (biologists, chemists, engineers) should find this volume of interest. For example, Volume 2 contents offer relevant knowledge on how to deal with (non)point source pollution issues exemplified by case studies taken from "real world situations", thereby enabling the right decisions to be taken to ensure protection of aquatic environments. Both Volumes 1 and 2 feature a broad review on toxicity testing applications, as well as a complete glossary of scientific/technical terms employed by editors/contributors in their respective chapters. In short, all groups directly or indirectly involved with the protection and conservation of freshwater environments will find Volume 2 appealing, as will those who simply wish to become familiar with the field of aquatic hazard assessment based on the use of bioassays.

Book Description

In Volume 1, 15 chapters on toxicity tests are described in great detail by way of a homogeneous structure that all contributors had to follow. These comprehensive texts allow readers to be informed of relevant information (background, theory, practice) linked to each bioassay. Hence, book contents can be used both for technology transfer purposes (e.g., classroom or workshop courses) and to undertake practical toxicity testing (e.g., in a private, public or university laboratory).

Academia (students, professors), government (environmental managers, scientists, regulators) and consulting professionals (biologists, chemists, engineers) should find this volume of interest. As an example, it should prove useful for conducting (under)graduate courses in aquatic toxicology involving practical laboratory training. In this respect, it can be attractive, owing to some of its contents, as a laboratory manual for learning purposes or for undertaking applied research to assess chemical hazards.

In short, all groups directly or indirectly involved with the protection and conservation of freshwater environments will find Volume 1 appealing, as will those who simply wish to become familiar with the field of toxicity testing.

In Volume 2, 11 chapters on hazard assessment schemes are described in great detail by way of a homogeneous structure that all contributors had to follow.

Description:
We report use of @b-cyclodextrin (CD)-hexamethylene diisocyanate (HMDI) copolymer(CDPU)-coated zirconia (CDPUZ) as a chiral stationary phase for separation of enantiomers of a set of 2,4-dinitrophenyl (DNP) amino acids in reversed-phase liquid chromatography. The effects of polymer loading on zirconia and HMDI/CD molar ratio in the preparation of CDPU on retention and selectivity in the separation of DNP-amino acids in were examined to find optimum polymer loading and HMDI/CD ratio. It was observed that 8% loading of the CDPU prepared with the HMDI/CD molar ratio of 4 gave the best separation of the amino acids investigated. Retention and chiral selectivity of CDPUZ were also compared to those for previously reported carboxymethyl-@b-CD-coated zirconia (CMCDZ). CDPUZ gave better chiral separation than CMCDZ for the DNP-amino acids.

Description:
A simple, inexpensive and efficient preconcentration and clean-up liquid-phase microextraction method (LPME) using porous polypropylene hollow fibre membrane was developed for the extraction of the antidepressant mirtazapine from human plasma. The effects of different parameters influencing the efficiency of extraction were described and optimized. Under optimized conditions, mirtazapine was extracted with 22@ml toluene from 0.7ml of plasma previously diluted with 3.1ml deionized water and alkalinized with 0.15ml 10M NaOH. Mefloquine was used as internal standard. The chromatographic analysis was carried out through chiral liquid chromatography (LC) using a Chiralpak AD column and hexane-ethanol (98:2, v/v) plus 0.1% diethylamine as mobile phase, at a flow rate of 1.5mlmin^-^1. Detection was carried out at 292nm. The mean recoveries of (+)-(S)- and (-)-(R)- mirtazapine were 29.1 and 28.8%, respectively. The quantification limit (LOQ) was 6.25ngml^-^1 with linear response over the 6.25-625ngml^-^1 concentration range for both enantiomers. Within-day and between-day assay precision and accuracy were studied at three concentration levels (15, 100 and 500ngml^-^1). For both mirtazapine enantiomers, the coefficients of variation (CV) and deviation from the theoretical values were lower than 15% at all concentration levels. The developed and validated method showed that LPME is a promising technique for sample preparation for the analyses of chiral drugs in biological samples.

Description:
A chiral separation method for glycidol enantiomers determination by normal-phase high-performance liquid chromatography coupled to atmospheric pressure chemical ionization mass spectrometry was developed. Two chiral stationary phases, amylose tris-(3,5-dimethylphenylcarbamate) (Chiralpak AD-H) and (S)-indoline-2-carboxylic acid and (R)-1-(@a-naphthyl) ethylamine (SUMICHIRAL OA-4900) have been investigated. The effects of the mobile phase composition, elution program and column temperature were also studied. Under the best conditions: Chiralpak AD-H column, mobile phase composition n-hexane:ethanol (70:30, v/v), flow rate of 0.8mL/min and 40^oC column temperature, a good resolution (Rs=1.6) for both enantiomers has been achieved with an analysis time of 16min. The method was found to be linear in the range from 100 to 500ppm for both glycidol enantiomers with a good determination coefficient (r^2 higher than 0.99) and good precision. Limits of detection of 31 and 50ppm for (R)-(+)-glycidol and (S)-(-)-glycidol, respectively, were obtained. The method was applied to the determination of the enantiomeric excess and yield obtained in a asymmetric epoxidation process of allyl alcohol with a chiral titanium-tartrate complex as catalyst.

Book Description

From its first publication in 1981, Lanark was hailed as a masterpiece and it has come to be widely regarded as the most remarkable and influential Scottish novel of the second half of the twentieth century. A work of extraordinary imagination and wide-ranging concerns, its playful narrative conveys at its core a profound message, both personal and political, about humankind's inability to love, and yet our compulsion to go on trying. With its echoes of Dante, Blake, Joyce, Kafka, and Lewis Carroll, Lanark has been published all over the world and to unanimous acclaim. This edition marks the novel's return to its original publisher and features a superb new introduction by the award-winning novelist Janice Galloway, and the author's Tailpiece, a fascinating addendum to the novel. "It was time Scotland produced a shattering work of fiction in the modern idiom. This is it." -- Anthony Burgess "Alasdair Gray is one of the most important living writers in English." -- Stephen Bernstein, The New York Times Book Review "Remarkable ... Lanark is a work of loving and vivid imagination, yielding copious riches." -- William Boyd, The Times Literary Supplement (London) "Undoubtedly the best work of fiction written by a Scottish author for decades." -- Time Out (London) "A quite extraordinary achievement, the most remarkable thing in Scottish fiction for a very long time." -- The Scotsman

A True Modern Classic.......2006-07-03

"Lanark" was first published in 1981, but its author spent 20 years writing it. And it's indeed a massive piece. The whole book is divided into four books (starting with book 3). I think it's one serious classic novel, sadly not as famous as it ought to be; but this here review will change that for the best. Of course.

This novel is a bit of two stories in one. There's a "surreal" story and a more autobiographical "realist" story. If I was to go into details, this would quickly become very complicated. It's not exactly an easy read, but it's worth it. I don't even know how I am going to say anything about it without going crazy...

The story begins in a world which at first seems fairly common, but quickly turns into something you're not familiar with. I won't say more on that, but it's a kind of hell, or afterlife of some sort. Within that frame, the second story occurs (or the first, since book 1 and 2 are the "realist" story and book 3 and 4 are the surreal world). The order of the books is: 3,1,2 and 4. I'm sure this sounds messy as hell but I promise it makes much more sense when you are into the book.

Book 1 and 2 are very much autobiographical of Gray's life, though not an actual biography. In short, Duncan Thaw (the main character) is a young boy living in Glasgow and we follow him throughout his (short) life, and then in the afterlife world, hence the subtitle of the book "a life in four books." Duncan is a very talented boy and grows up to be an art student (Gray worked as an art teacher for a long time, and is a great painter himself, he did all the illustrations found in Lanark). I can't say enough those two books, I think I prefer them over the surreal ones but they're not quite comparable.

As to book 3 and 4, I'll give you a tiny taste of it with the following stuff: the story begins in the city of Unthank, and it's a bit of an urban hell where the sun shines for a few minutes each day. That's where Lanark is, and he has no memories of his past. He wants sunshine and love. In that world, people "disappear," and that won't make sense till you're further into the novel. But I'll tell you what, people get strange diseases in this world, and these diseases reflect the problem with them. Eventually everyones is... can I even say that without sounding completely weird... everyone is swallowed by giant mouths into the "institute," which is a place much like hell, only it's an hospital where these people, who have "disappeared," are treated. I won't say more because it's important that you find out for yourself (and anyway summing this stuff up is just like talking about an acid trip).

Gray is a really brilliant writer and his books 1 and 2 are stuff to be worshipped. Maybe I'll post selected bits later on in this thread. I really recommend this for anyone interested in something that will surely be looked upon as one of the best novels ever written in the universe (no less). It's already a big classic in contemporary literature, but my guess is it won't cease to grow.

It's only worth reading books one and two.......2003-02-10

Maybe I missed something, but this didn't do a lot for me. It's a jumbled up ragbag of ideas which don't fit together coherently while its characters are unlikeable and without much individuality.
The story starts in a depressing world called Unthank, and follows the character Lanark as he arrives in town. He craves for sunlight in a world where there is none and since he's fast turning into a dragon he decides to throw himself down a large mouth in the ground (as you do...).
He comes out the other end in an institute where he is cured of his dragonhide and becomes a doctor for a short while before, like me, getting very bored and frustrated with the place.
So he decides to leave but that's quite dangerous involving a trip across an intercalendrical zone. Inevitably he leaves the hospital and takes along his girlfriend who, unsatisfyingly, doesn't seem to display any affection towards him at all.
In the intercalendrical zone, time moves erratically, and his girlfriend discovers she's heavily pregnant. They return to Unthank in the expectation that shortly the place will be swallowed by an even larger mouth and they'll be transferred to a sunnier land.
But Rima leaves Lanark, taking the (talking) baby with her. Lanark is then sent on a mission to return to the institute to ask them to save Unthank, which has suffered a pollution spill that threatens to destroy the place. At the institute he is stitched up by his rivals and finds time to meet the author of the book, who spends a chapter trying to explain what the hell the book is about. Lanark returns from the institute to Unthank in time to witness the place destroyed.
Books one and two in the middle tell the story of Duncan Thaw (Lanark before arriving in book three) and surprisingly this part of the book is a lot more readable. The chapters follow Thaw as he grows from a child to a sickly adult. There are some parallels with the Lanark story (Thaw is emotionally inhibited, he suffers an illness as a result, he can't keep hold of the girl he likes). In my opinion, if this story stood alone it would be a much more satisfying read. It's very reminiscent of the writer Iain Banks who no doubt was inspired by Gray. Interesting also the split between contemporary fiction and sci-fi which Banks also practices. However, in my opinion, a book like Walking On Glass by Banks is far superior to Lanark in that it made me think about the connections between the strands of the stories.
I suppose my review is a little biased because I'm not a huge fan of science fiction any more. But since the author asserts in his incarnation as god in the final chapters that he doesn't write science fiction I suppose I shouldn't worry.

A bleak yet compelling vision of survival.......2003-02-09

First published in 1981 and set in the dystopic cities of Unthank and Glasgow, Lanark: A Life In Four Books by Alasdair Gray is an emotional and starkly brilliant saga about the struggle to love despite contradictions and vices in human nature that attack bonds of care or trust. A bleak yet compelling vision of survival and the endless search for something more in life, Lanark consists of parallel tales of an eponymous hero living in a bizarre city of the future called Unthank, and Duncan Thaw, a young Glaswegian of the twentieth century. This edition of Lanark is enhanced with a new foreword by novelist Janice Galloway and includes Alasdair Gray's "Tailpiece" which serves as an unusual addendum to this surreal and highly recommended novel.

Daunting to be the first.......2003-01-11

I don't know if no one has reviewed this tome for fear of where angels tread lightly or what, but I have to say something about this amazing book, if for no other reason than to start a dialogue.

I first heard of this book from a Village Voice article about the republication of "Lanark" in a four-volume set. The structure of this edition is that it begins with Book 3, followed by the Prologue, Book 1, Book 2, and Book 4 is divided by an Epilogue that takes place 4 chapters from the end. This convoluted structure actually makes the book rather fascinating, in that Gray has said that he wishes for the book to be remembered in a certain order, which is why he put "Book 3" first. This edition also features artworks by the artist at the front of each Book, and the Epilogue features some interesting typesetting.

For readers of science fiction, this book will offer an interesting challenge, for books 1 and 2 are more a coming-of-age of the artist sort of affair. Books 3 and 4 center around the Lanark character, who is called Thaw in 1 and 2. The Thaw books reminded me many times of Maugham and Joyce, while 3 and 4 seemed positively Dickian. (Not to be confused with Dickensian, which slant-applies, if at all.) There's a lot of ferocious literariness going on in this book, yet there's all sorts of humor. And also a slice of life in a city I know absolutely nothing about. The depictions and commentary on Glasgow reveal a lot about the self-consciousness of 2nd-tier and below cities--the cities that are not New York, London, Florence, Paris, Moscow, etc.
