Measuring environmental hazards defined

An importer or manufacturer may only supply a substance , product (ie, formulated prqiaration) or article if its environmental impact has been assessed, and it can justifiably be assumed that handling in accordance with the information on the label and the instructions for use cannot present a hazard to the environment or to persons indirectly through the environment. Furthermore, the customer must receive appropriate information, in the form of labelling, instructions for use and MSDSs, if there will be environmentally hazardous applications or methods of disposal. The format of MSDSs and the information content is defined in OEHS (Annex 2.2 for substances and Annex 2.3 for products ). The hazards for the environment and the protective measures must be indicated on the... 

The boiling point serves as an indicator of a chemical s physical state at ambient conditions. Mostly it is not used as an autonomous parameter in environmental hazard assessments, but for estimating further properties such as the vapour pressure. The boiling point is defined as the temperature at which the vapour pressure of a liquid is equal to the pressure of the atmosphere on the liquid (Rechsteiner, 1990). The measurement of boiling points is in principal simple, requiring only a calibrated thermometer, but the results may be severely affected by ... 

The IR detection method will work for more than 300 of the approximately 500 gases and vapors declared hazardous by the Occupational Safety and Health Administration (OSHA). It is also claimed to detect and measure many of the 189 hazardous air pollutants defined by the Environmental Protection Agency (EPA).8... 

A precursor to a toxicity index is the common use of tests to rank environmental samples or hazardous sites according to the severity of the toxic responses. Toxicity ranking defines priority for action on the most toxic effluents or contaminated sites. Ranking the samples can become complicated if toxicity has been measured with several tests that produced variations in rank. Joining the responses into a toxicity index would express potential hazard in a single number. 

Many metal pollutants (e.g. mercury, cadmium, lead, nickel and zinc) are hazardous to human health and terrestrial ecosystems. The determination of metals in contaminated soils may be carried out for a variety of reasons, such as measurement of total or defined extractable content, which provides knowledge of soil components in respect of changes in soil composition produced by natural or anthropogenic contamination. In addition, the analysis may be designed to investigate and categorise degrees of contamination of land for current or intended use. An environmental survey of a polluted site may be undertaken to obtain information about the nature, quantity, distribution and behaviour of contaminants and, if necessary, to select the most appropriate use of the site (Hester Harrison 2001 Kibblewhite 2001). 

The Globally Harmonized System of Classification and Labelling of Chemicals (CHS) Presents a brief overview of the United Nations Globally Harmonized System of Classification and Labelling of Chemicals (GHS) for defining and communicating hazard information and protective measures related to the physical, health, and environmental risks of chemicals through product labels and safety data sheets (SDSs).
