The understanding that some pesticides are more hazardous than others is well established. Recognition of this is reflected by the World Health Organization (WHO) Recommended Classification of Pesticides by Hazard, which was first published in 1975. The document classifies pesticides in one of five hazard classes according to their acute toxicity. In 2002, the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) was introduced, which in addition to acute toxicity also provides classification of chemicals according to their chronic health hazards and environmental hazards.
A comprehensive guide to the establishment of screening and surveillance programmes as a strategy for protecting the health of workers exposed to respirable crystalline silica containing dust, coalmine dust, and asbestos dust. Addressed to health planners as well as specialists in occupational health, the book covers both the general principles of effective screening and surveillance and the specific approaches, methodologies, tests, and examinations useful for detecting diseases induced by exposure to mineral dust. Recommended approaches and practices reflect the consensus reached by an international group of experts. Background information is provided in the opening chapters, which explain differences in the aims and methods of screening and surveillance programmes, offer advice on the selection of appropriate medical tests, and discuss essential programme components. Against this background, the most extensive part offers detailed guidance concerning which diseases should be monitored and which tests should be performed. All the major diseases associated with mineral dust exposure are reviewed, emphasizing knowledge about causes, pathological characteristics, manifestations, latency period, the advantages of early diagnosis, and the effectiveness of available interventions. On the basis of this review target diseases for screening and surveillance are identified. The next chapter discusses the uses and limitations of each test commonly used to detect diseases related to mineral dust exposure. Tests are discussed in the categories of conventional chest radiography, additional imaging techniques, measures of lung function, and questionnaires. The final chapter sets out recommendations for the periodic screening and health surveillance of workers.
This book represents a comprehensive review of current concepts concerning the development, progression, and treatment of silica-induced lung diseases. The text begins with a complete review of the historical evolution of our understanding of silicosis and a discussion of the clinical and pathological features of this disease. It presents critical questions that must be resolved and then details state-of-the-art experiments that address these problems. The book presents an extensive discussion of new technologies that have increased our understanding of the relationship of surface properties of particulates to their cytotoxicity and pathogenicity. It also presents data that explain the intracellular and intercellular mechanisms involved in the pulmonary response to silica exposure.
This Child-Friendly Schools (CFS) Manual was developed during three-and-a-half years of continuous work, involving the United Nations Children's Fund education staff and specialists from partner agencies working on quality education.

Mixed race studies is one of the fastest growing, as well as one of the most important and controversial areas in the field of race and ethnic relations. Bringing together pioneering and controversial scholarship from both the social and the biological sciences, as well as the humanities, this reader charts the evolution of debates on 'race' and 'mixed race' from the nineteenth to the twenty-first century.

This collection adds a new dimension to the growing body of literature on the topic and provides a comprehensive history of the origins and directions of 'mixed race' research as an intellectual movement. For students of anthropology, race and ethnicity, it is an invaluable resource for examining the complexities and paradoxes of 'racial' thinking across space, time and disciplines.
