M/258 - Pb, Cd, As & Ni in ambiant air
Standardization mandate to CEN and CENELEC for standard measuring methods of Pb, Cd, As, Ni in ambiant air
Mandate M/258 requests the European standardisation organisations CEN and CENELEC to develop and establish standardized measuring methods for lead (Pb), cadmium (Cd), arsenic (As), and nickel (Ni) in ambient air. The mandate aims to ensure consistent, reliable, and comparable monitoring of these hazardous substances across member states to support environmental and public health policies. The decision involves approving or disapproving the mandate as referenced in resolution CEN/BT C154/1997.
Purpose
This mandate aims to standardize measurement methods for detecting lead (Pb), cadmium (Cd), arsenic (As), and nickel (Ni) in ambient air. Establishing common standards ensures consistency, reliability, and comparability of air quality monitoring across European countries.
Standardisation request
The European Commission requested CEN (European Committee for Standardization) and CENELEC (European Committee for Electrotechnical Standardization) to develop standardized methods. These methods should focus specifically on measuring concentrations of Pb, Cd, As, and Ni in ambient air, facilitating harmonized environmental monitoring and regulatory compliance within the EU.
Expected deliverables
- Development of European Standards (ENs) for measuring lead, cadmium, arsenic, and nickel in the ambient air.
- Standardized procedures ensuring accuracy, repeatability, and reproducibility of measurements.
- Possibly guidelines or protocols that laboratories and monitoring stations should follow.
Context
Heavy metals such as Pb, Cd, As, and Ni are critical pollutants due to their toxicity and persistence in the environment. Monitoring their concentrations in ambient air is important for protecting public health and the environment. This mandate supports EU environmental policies and directives related to air quality and pollutant emissions. The resolution reference CEN/BT C154/1997 indicates formal approval or consideration by CEN's Board at that time, integrating this mandate into European standardization activities.
The mandate covers the development of standard measuring methods for lead (Pb), cadmium (Cd), arsenic (As), and nickel (Ni) in ambient air to support environmental monitoring and pollution control.

This European Standard specifies a method for the determination of particulate lead (Pb), cadmium (Cd), arsenic (As) and nickel (Ni) in ambient air that can be used in the framework of the European Council Directive on Ambient Air Quality Assessment and Management [1] and the 1st [2] and 4th [3] Daughter Directives. Performance requirements with which the method has to comply are specified in this European Standard. The performance characteristics of the method were determined in comparative field validation tests carried out at four European locations (see [4]).
This European Standard specifies a method for sampling of Pb, Cd, As and Ni as part of the PM10 aerosol, microwave digestion of the samples and analysis by graphite furnace atomic absorption spectrometry or by inductively coupled plasma (quadrupole) mass spectrometry.
This European Standard is applicable for the measurement of Pb, Cd, As and Ni as part of the PM10 aerosol fraction in the concentration ranges listed in Table 1.
Table 1 - Working ranges of the method in ng/m³
From To
Pb 1 4 000
Cd 0,1 50
As 0,5 350
Ni 2 100
The actual lower limits of the working ranges depend upon the variability of the laboratory filter blank (5.3.1). The lower limits of the working ranges given in Table 1 are expected values based upon performance achieved in the field validation tests. Similarly the upper limits of the working ranges have been set arbitrarily based upon the maximum daily values measured during the field validation tests. The method can be applied to higher concentrations provided the PM10 collection characteristics of the sampler are not compromised.

Frequently Asked Questions
A European Standardization Mandate is a formal request from the European Commission to the European Standardization Organizations (CEN, CENELEC, and ETSI) to develop European standards (ENs) in support of EU legislation and policies. Mandates are issued under Regulation (EU) No 1025/2012 and help ensure that products and services meet the essential requirements set out in EU directives and regulations.
M/258 is a European Standardization Mandate titled "Standardization mandate to CEN and CENELEC for standard measuring methods of Pb, Cd, As, Ni in ambiant air". Standardization mandate to CEN and CENELEC for standard measuring methods of Pb, Cd, As, Ni in ambiant air There are 4 standards developed under this mandate.
Standards developed in response to a mandate and cited in the Official Journal of the European Union become "harmonized standards". Products manufactured in compliance with harmonized standards benefit from a presumption of conformity with the essential requirements of the corresponding EU directive or regulation, facilitating CE marking and market access across the European Economic Area.
