This Test Guideline describes methods to determine the surface tension (in N/m) of aqueous solutions. The methods are based on the measurement of the force which it is necessary to exert vertically on a stirrup or ring, in contact with the surface of the liquid, in order to separate it from the surface, or on a plate, with an edge in contact with the surface, in order to draw up the film that has formed. There are four different methods: the plate method, the stirrup method, the ring method and the OECD harmonized ring method. They are described in detail in the ISO Standard 304-1985. The methods described are applicable to aqueous solutions of most substances regardless of their degree of purity. The concentration should be 90% of the saturation solubility, but must below 1g/l. This shall therefore be carried out under a protective cover to avoid interference at 20°C approximately. The ring is immersed below the surface of the solution. Then the table top, where the measurement vessel is placed, is lowered gradually and evenly at a rate of approximately 0.5 cm/min to detach the ring from the surface until the maximum force is reached. The force is read on the tensiometer. After completing the first measurement, measurements are repeated until a constant surface tension value is reached.

Annotation This book describes the different tests that must be performed on new chemicals and other materials to demonstrate to the regulatory authorities that they are safe for use. Tests vary from physico-chemical, measuring properties such as melting point and density, through genetic toxicity studies, to mammalian toxicology and studies to investigate effects on the environment. This book describes clearly the process of obtaining approval for use in a variety of global regions and across different applications. It also explains why different tests are performed and the implications of the results.

At last – a second edition of this hugely important text that reflects the progress and experience gained in the last decade and aims at providing background and training material for a new generation of risk assessors. The authors offer an introduction to risk assessment of chemicals as well as basic background information on sources, emissions, distribution and fate processes for the estimation of exposure of plant and animal species in the environment and humans exposed via the environment, consumer products, and at the workplace. The coverage describes the basic principles and methods of risk assessment within their legislative frameworks (EU, USA, Japan and Canada).

This book focuses on the principles, methods, and interpretation involved in establishing the safety, risk, and hazard assessment of small molecules. It presents the regulatory requirements for risk and hazard identification as per the guidelines of the Organization for Economic Cooperation and Development (OECD), Paris, and the International Council for Harmonisation (ICH) of Technical Requirements for Pharmaceuticals for Human Use ICH and Schedule ‘Y’, India. It serves as reference material for undergraduate and postgraduate pharmacy degree students as well as senior researchers to learn about the principles, methods, and interpretations of systemic dosage (acute and repeated dose) and genotoxicity (in vitro and in vivo), special toxicological investigations such as reproductive and developmental toxicology, carcinogenicity, and toxicokinetics using animal models or in vitro methods, as applicable. This book is the first of its kind in providing information on the principles and methods of implementation of Good Laboratory Practice based on the guidelines of OECD. It includes detailed chapters about the regulatory requirements and guidelines in pharmaceutical products and agrochemicals. It also describes the infrastructure needed for preclinical studies, including in vivo and in vitro facilities.

Understand the fundamentals of human risk assessment with this introduction and reference Human risk assessments are a precondition for virtually all industrial action or environmental regulation, all the more essential in a world where chemical and environmental hazards are becoming more abundant. These documents catalog potential environmental, toxicological, ecological, or other harms resulting from a particular hazard, from chemical spills to construction projects to dangerous workplaces. They turn on a number of variables, of which the most significant is the degree of human exposure to the hazardous agent or process. Human and Ecological Risk Assessment combines the virtues of a textbook and reference work to introduce and analyze these vital documents. Beginning with the foundational theory of human health risk assessment, it then supplies case studies and detailed analysis illustrating the practice of producing risk assessment documents. Fully updated and authored by leading authorities in the field, the result is an indispensable work. Readers of the second edition of Human and Ecological Risk Assessment will also find: Over 40 entirely new case studies reflecting the latest in risk assessment practice Detailed discussion of hazards including air emissions, contaminated food and soil, hazardous waste sites, and many more Case studies from multiple countries to reflect diverse international standards Human and Ecological Risk Assessment is ideal for professionals and advanced graduate students in toxicology, industrial hygiene, occupational medicine, environmental science, and all related subjects.
