BS EN 16414:2014EN 16414:2014 (E) 4 0 Introduction 0.1 Biomonitoring and air quality The impact of air pollution is of growing importance worldwide. Local and regional assessment is necessary as a first step to collect

20、fundamental information, which can be used to avoid, prevent and minimize harmful effects on human health and the environment as a whole. Biomonitoring may serve as a tool for such a purpose. As the effects on indicator organisms are a time-integrated result of complex influences combining both air

21、quality and local climatic conditions, this holistic biological approach is considered particularly close to human and environmental health end points and thus is relevant to air quality management. It is important to emphasize that biomonitoring data are completely different from those obtained thr

22、ough physico-chemical measurements (ambient concentrations and deposition) and computer modelling (emissions data). Biomonitoring provides evidence of the effects that airborne pollutants have on organisms. As such it reveals biologically relevant, field-based, time- and space-integrated indications

23、 of environmental health as a whole. Legislation states that there should be no harmful environmental effects from air pollution. This requirement can only be met by investigating the effects at the biological level. The application of biomonitoring in air quality and environmental management requir

24、es rigorous standards and a recognized regime so that it can be evaluated in the same way as physico-chemical measurements and modelling in pollution management. Biomonitoring is the traditional way through which environmental changes have been detected historically. Various standard works on biomon

25、itoring provide an overview of the state of the science at the time, e.g. 1, 2, 3 The first investigations of passive biomonitoring are documented in the middle of the 19th century: by monitoring the development of epiphytic lichens it was discovered that the lichens were damaged during the polluted

26、 period in winter and recovered and showed strong growth in summer 4. These observations identified lichens as important bioindicators. Later investigations also dealt with bioaccumulators. An active biomonitoring procedure with bush beans was first initiated in 1899 5. 0.2 Biomonitoring and EU legi

27、slation Biomonitoring methods in terrestrial environments respond to a variety of requirements and objectives of EU environmental policy primarily in the fields of air quality (Directive 2008/50/EC on ambient air, 6), integrated pollution prevention and control (Directive 2008/1/EC, 7, and Directive

28、 2010/75/EU, 8) and conservation (Habitats Directive). The topics food chain (9) and animal feed (10, 11, 12) are alluded to as well. For air quality in Europe, the legislator requires adequate monitoring of air quality, including pollution deposition as well as avoidance, prevention or reduction of

29、 harmful effects. Biomonitoring methods appertain to the scope of short and long-term air quality assessment. Directive 2004/107/EC of 15 December 2004 relating to arsenic, cadmium, mercury, nickel and polycyclic aromatic hydrocarbons in ambient air (13) states that “the use of bio indicators may be

30、 considered where regional patterns of the impact on ecosystems are to be assessed”. Concerning IPPC from industrial installations, the permit procedure includes two particular environmental conditions for setting adequate emission limit values. The asserted concepts of “effects” and “sensitivity of

31、 the local environment” open up a broad field for biomonitoring methods, in relation to the general impact on air quality and the deposition of operational-specific pollutants. The basic properties of biomonitoring methods can be used advantageously for various applications such as reference invento

32、ries prior to the start of a new installation, the mapping of the potential pollution reception areas and (long-term) monitoring of the impact caused by industrial activity. The environmental inspection of installations demands the examination of the full range of environmental effects. For the publ

33、ic authority, biomonitoring data contribute to the decision-making process, e.g. concerning the question of tolerance of impacts at the local scale. The Habitats Directive (92/43/EEC on the conservation of natural habitats and of wild fauna and flora 14) requires competent authorities to consider or

34、 review planning permission and other activities affecting a European designated site where the integrity of the site could be adversely affected. The Directive also BS EN 16414:2014EN 16414:2014 (E) 5 provides for the control of potentially damaging operations, whereby consent may only be granted o

35、nce it has been shown through appropriate assessment that the proposed operation will not adversely affect the integrity of the site. The responsibility lies with the applicant to demonstrate that there is no adverse effect on such a conservation area. For this purpose, biomonitoring is well suited

36、as a non-intrusive form of environmental assessment. As an important element within its integrated environmental policy, in 2003 the European Commission adopted a European Environment and Health Strategy (15) with the overall aim of reducing diseases caused by environmental factors in Europe. In Cha

37、pter 5 of this document it is stated that the “community approach entails the collection and linking of data on environmental pollutants in all the different environmental compartments (including the cycle of pollutants) and in the whole ecosystem (bio-indicators) to health data (epidemiological, to

38、xicological, morbidity)”. The European Environment and Health Action Plan 2004-2010 (16) which followed the adoption of this strategy focusses on human biomonitoring, but emphasizes the need to “develop integrated monitoring of the environment, including food, to allow the determination of relevant

39、human exposure“. 0.3 Biomonitoring with in situ mosses Mosses in the strict sense are non-vascular plants belonging to the Bryophyta phylum. They are composed of a leafy stem (or gametophyte) bearing reproductive organs and one or more sporophytes, made up of a capsule attached to the end of a stalk

40、 that grows out of the gametophyte. According to the morphology of the moss and the position of the sporophytes, mosses are sorted into the pleurocarpous or acrocarpous main types. For most mosses, the lack of roots, vascular system, or protective cuticle means that water and nutrients come mainly f

41、rom dry, wet and occult deposition. Therefore contaminant levels in tissues of terrestrial mosses originate mainly from the atmosphere. The high surface-to-volume ratio, the large contact surface due to many leaves overlapping around the stem, as well as thin leaves (made of a single cell-layer), en

42、able mosses to trap particles efficiently. As a result, particulate and dissolved air contaminants are taken up and retained by mosses, either on leaf surfaces or inside moss tissues. For these reasons, terrestrial mosses have been commonly used in air monitoring programmes as bioaccumulators of a w

43、ide range of atmospheric contaminants, particularly mineral compounds and elements, especially metals but also organic substances (persistent organic pollutants) and radioactive isotopes (17, 18). BS EN 16414:2014EN 16414:2014 (E) 6 1 Scope This European Standard describes the sampling protocol and

44、the preparation of samples of in situ mosses to monitor the bioaccumulation of atmospheric contaminants. This European Standard specifies the actions that shall be taken from the field sampling of mosses to their final preparation before analysis for targeted contaminants. This European Standard is

45、of interest to all operators wishing to conduct air quality biomonitoring studies. 2 Terms and definitions For the purposes of this document, the following terms and definitions apply. 2.1 biomonitoring use of biological systems (organisms and organism communities) to monitor environmental change ov
