The method described in this Test Guideline is based on soil column chromatography in disturbed soil. Two types of experiments are performed to determine (i) the leaching potential of the test substance, and (ii) the leaching potential of transformation products in soils under controlled...

This Test Guideline describes a laboratory test method designed to investigate long term potential effects of a single exposure of agrochemicals/non agrochemicals on carbon transformation activity of soil microorganisms. A minimum of two test concentrations are recommended for agrochemicals...

This Test Guideline is designed for assessing the effects of chemicals on the reproduction of collembolans in soil. The parthenogenetic Folsomia candida is the recommended species for use, but an alternative species such as sexually reproducing Folsomia fimetaria could also be used if they meet...

The method described in this Test Guideline is designed for the evaluation of the mineralisation rate of a 14C-labelled compound in soil. The method is applicable to volatile or non-volatile, soluble or insoluble compounds which are not inhibitory to micro-organisms. The basic test consists on...

This Test Guideline describes a laboratory test method designed to investigate the long-term effects of chemicals, after a single exposure, on nitrogen transformation activity of soil microorganisms. Sieved soil is amended with powdered plant meal and either treated with the test substance or...

This book presents a comprehensive overview and assessment of China's agricultural policies combined with OECD estimates of the level of support provided to the Chinese farm sector. It also examines such issues as welfare impacts of liberalisation; Chinese agricultural commodity markets; grain...

The Italian city of Cattolica has developed an urban complex, the Piazza della Repubblica, providing a wide range of services to the public. In renovated facilities, the complex provides a modern and rational architectural setting based on the idea of the traditional town square or "piazza", an...

Urban areas represent an important part of the national economy and feature higher GDP per capita and productivity levels than their country’s average. But they also harbour large pockets of unemployment and poverty and suffer from problems such as congestion, pollution and crime. This book...

This study provides an empirical review of the role of governments, the private sector, regional economic institutions and the broader international community in driving economic diversification. Individual case studies of five African economies describe both the catalysts of and barriers to...
