This book discusses bioavailability concepts and methods, summarizing the current knowledge on bioavailability science, as well as possible pathways for integrating bioavailability into risk assessment and the regulation of organic chemicals. Divided into 5 parts, it begins with an overview of chemical distribution in soil and sediment, as well as the bioavailability and bioaccumulation of chemicals in plants, soil, invertebrates and vertebrates (including humans). It then focuses on the impact of sorption processes and reviews bioavailability measurement methods. The closing chapters discuss the impact of bioavailability studies on chemical risk assessment, and highlights further research needs. Written by a multi-disciplinary team of authors, it is an essential resource for scientists in academia and industry, students, as well as for authorities.

Conceived of as the 'New World', Latin America represented a new beginning for its discoverers, yet, in fact, the colonials were only continuing their search for what they knew all along they wanted to find: fertile land with an abundance of spices, precious metals and labour. This idea of Latin America's invention has long been a preoccupation of intellectuals and historians, leading to the dominant postcolonial interpretation of the native as a marginalized figure often unusually wise or heroic according to his circumstances. "Transatlantic Translations" examines the ways in which the unknown has always been imagined according to what is already known, the new according to the old. Tracing Latin American representations from the early modern to contemporary periods, in Shakespeare, Cervantes, Juan Rulfo, Ricardo Palma, Gabriel Garcia Marquez, Juan Maria Gutierrez and many others, Ortega uncovers the rich fabric of literature that has emerged from that culture, arguing that the learning of language, far from being a means for the colonial to indoctrinate and civilize the native, has given the native the means to describe and communicate with the natural world around them, and eventually to re-tell their own history. By travelling beyond the contradictions that make up any comparison between colonizer and native, Ortega negotiates a space for the Latin American narrative beyond ideas of victimization and resistance. "Transatlantic Translations" bridges the divide between abundance and scarcity, enabling the Old World and the New to meet and speak together in a shared language.

Too often literary criticism is academic exercise rather than creative act. For the multifaceted Julio Ortega--respected poet, dramatist, and novelist in his own right--the act of criticism becomes profoundly creative, his incisive readings of the text far transcending the pedantry that may falsely pass for imagination, intelligence, and rigor. Nearly every Spanish-American writer of consequence, from Paz to Fuentes, Cortazar to Lezama Lima, has extolled Ortega's criticism as not merely a reflection but an essential part of the renaissance that took place in Spanish-American letters during the late twentieth century. Poetics of Change brings together Ortega's most penetrating and insightful analyses of the fiction of Borges, Fuentes, Garcia Marquez, Carpentier, Rulfo, Cabrera Infante, and others responsible for great writing from Spanish America. Ortega concerns himself most with the semantic innovations of these masters of the modern narrative and their play with form, language, and the traditional boundaries of genre. Mapping their creative territory, he finds that the poetics of Spanish-American writing is that of a dynamically changing genre that has set exploration at its very heart.

Together with the late Jorge Luis Borges, Gabriel Garcia Marquez, the 1982 Nobel laureate, stands at the pinnacle of Latin American literature. His work, in the words of Julio Ortega, "contains its own 'deconstructive' force--a literary power capable of reshaping natural order and rhetorical tradition in order to 'carnivalize' the Borges' library and allow us to hear the voices--and the laughter--of a culture, that of Latin America." This reshaping force invites us to read the works of Garcia Marquez in a new way, one that bypasses the traditional, inadequate approaches through Latin American politics, history, and "magical realism."

In Gabriel Garcia Marquez and the Powers of Fiction, noted scholars Julio Ortega, Ricardo Gutierrez Mouat, Michael Palencia-Roth, Anibal Gonzalez, and Gonzalo Diaz-Migoyo offer English-speaking readers a new approach to Garcia Marquez's work. Their poststructuralist readings focus on the peculiar sign-system, formal configuration, intradiscursivity, and unfolding representation in the novels One Hundred Years of Solitude, No One Writes to the Colonel, In Evil Hour, The Autumn of the Patriarch, and Chronicle of a Death Foretold and in several of the author's short stories. Also included as an appendix is a translation of Garcia Marquez's Nobel Prize acceptance speech, "The Solitude of Latin America."

In The Vintage Book of Latin American Stories, Julio Ortega and Carlos Fuentes present the most compelling short fiction from Mexico to Chile. Surreal, poetic, naturalistic, urbane, peasant-born: All styles intersect and play, often within a single piece. There is "The Handsomest Drown Man in the World," the García Márquez fable of a village overcome by the power of human beauty; "The Aleph," Borges' classic tale of a man who discovers, in a colleague's cellar, the Universe. Here is the haunting shades of Juan Rulfo, the astonishing anxiety puzzles of Julio Cortázar, the disquieted domesticity of Clarice Lispector. Provocative, powerful, immensely engaging, The Vintage Book of Latin American Stories showcases the ingenuity, diversity, and continuing excellence of a vast and vivid literary tradition.
