PRIO – A tool for Risk Reduction of Chemicals

Glossary

Articles
General term referring to all products on the market.

BCF
BioConcentration Factor. Gives a value for the concentration of a substance inside the organism compared with the surrounding environment (often water).

Bioconcentration
Accumulation of a substance in organisms in a higher concentration than in the surrounding environment.

Bioaccumulative substances/ bioaccumulation
Accumulation of a substance in organisms in a higher concentration than in the surrounding environment or food.

Chemical products
Chemical/chemical product: chemical substance and preparations (mixtures) of chemical substances. Chemical products may be specially regulated products, e.g. pesticides, and generally regulated products, i.e. all other chemical products.

Classification
Assessment of the degree of environmental or health hazard of a substance. The classification is determined on the basis of Regulation (EC) No 1272/2008 on classification and labelling of substances and mixtures (CLP), which came into force 20 January 2009. During a transitional period, until 2015, this new regulation and the Swedish Chemicals Agency's regulations on the classification and labelling of chemical products (KIFS 2005:7) are both valid.

CLP
Regulation (EC) No 1272/2008 of the European Parliament and of the Council on classification and labelling of substances and mixtures (CLP). The regulation came into force on 20 January 2009.

CMR substances
Substances that are Carcinogenic, Mutagenic or toxic to Reproduction.

Complex hydrocarbons
Fractions that are extracted from oil or coal. These substances are classified in the Classification List, KIFS 2005:7.

Derivative
"Derived" chemical compound where one or more hydrogen atoms in a parent compound has been replaced by another atom or other atoms and/or group(s). For example, chlorobenzene, C6H5Cl, is a derivative of benzene, C6H6.

EC number
Identification number of chemical substances on the EU market. An inventory was made in 1981 to ascertain which substances exist on the market and which are new. Around 100,000 "existing substances" were reported. In the EC no. system, these substances always start with the base 200. New substances always start with the base 400.

Ecosystem
A delimited community of organisms that constitutes a unit in nature, e.g. a lake, section of terrain or a forest area with its flora and fauna.

Endocrine disruptive substance
Chemical substances that damage or disrupt the function of the body's endocrine (hormone-producing and -secreting) glands, affect the metabolism of hormones, or disrupt the impact of the hormones on the target organs.

Exposure assessment
Assessment of the extent to which people and the environment come into contact with hazardous substances.

Incidence
A measure used in epidemiolgy for the occurrence of disease in a population. Incidence indicates how many new cases, e.g. of myocardial infarction or gastric ulcers, occur during a particular period of time in a particular population group. The incidence indicates the number of cases per 100, 1,100 persons etc. per unit of time (year, 5-year period etc.).

KIFS
Short form for the Swedish Chemicals Agency's Code of statutes.

KIFS 2005:7 Swedish Chemicals Agency's regulations on the classification and labelling of chemical products.

Mutagenic
Substance that damages the genetic material.

Observation List
Older end Publication from the National Chemicals Inspectorate that contained criteria for substances requiring special attention and a list of examples of substances that meet these criteria. PRIO is a development of the Observation List and replaces it.

Ozone-depleting
Substances that may endanger the structure or function of the ozone layer of the stratosphere, i.e. fulfil classification criterion R59 (H420 or EUH059 in CLP).

PBT/vPvB
(persistent, bioaccumulative, toxic) chemicals that are persistent, bioaccumulative and toxic; vPvB (very persistent and very bioaccumulative) chemicals that are very persistent and very bioaccumulative, i.e. is stored in tissues.

Persistent
Persistence implies that a substance will be stable in the environment resisting chemical, physical and biological transformation reactions leading to degradation.

Phase-out substance
Substances with inherent properties that fulfill the criteria for one of the prioritisation levels of the PRIO tool.

Population
A collection of individuals of a species within a particular area.

PRIO
Name of the web tool. Abbreviated form of priority-setting guide.

Prioritisation level
Different levels in PRIO, e.g. phase-out or priority risk reduction.

Product information sheet
Same as safety data sheet.

Products register
By law, anyone who manufactures or imports a chemical product in Sweden in quantities exceeding 100 kg per year must notify this to a register at the Swedish Chemicals Agency.

REACH
(Registration, Evaluation and Authorisation of Chemicals) A collective term for the EU chemicals legislation, regulation (EC) No 1907/2006.

Priority risk-reduction substance
Substance for which the risk should be assessed.

Safety data sheet
(SDS) Information that must always exist for chemical products hazardous to health or the environment according to REACH, article 31. Must be formulated in accordance with REACH, annex II.

Substitution
Replacement of a substance with a less hazardous substance or alternative technology.

Toxic to reproduction
Substance that harms the ability to reproduce.
