Environmental quality standards EQS

The BASIC toxicity database contains information on the aquatic toxicity of a number of hazardous substances. In many cases, the information is given as some sort of safe level such as UK Environmental Quality Standards (EQSs) or the national/international equivalent. For substances for which no such levels have been set, a brief literature review was performed in order to produce an environmental hazard/risk assessment. 

Provisional Environmental Quality Standards (EQSs) as Proposed in the Common Position Adopted by the Council on December 20, 2007, with a View to the Adoption of a Directive of the European Parliament and of the Council on EQSs in the Field of Water Policy and Amending Directives 82/176/EEC, 83/513/EEC, 84/156/EEC, 84/491/EEC, 86/280/EEC, and 2000/60/EC... 

Environmental quality standards (EQSs) are widely used to help protect the environment and human health and are considered by many to consist simply of the stated limit value for a substance plus, perhaps, the time over which the standard applies. An example of this might be an annual average EQS for lead in water of 7.2 pg Ir1 to protect the freshwater environment as proposed in the Water Framework Daughter Directive on EQS (European Commission [EC] 2006). 

This chapter deals with the derivation of aquatic environmental quality standards (EQSs), including standards for the protection of water dwellers, predators of water dwellers, and human water users. However, the main focus is on standards for the protection of organisms that live in water or aquatic sediment and are able to absorb contaminants directly via their gills, skin, and/or cell surfaces. In other words, the chapter primarily covers the derivation of standards for the protection of aquatic ecosystems.

It is appropriate to have different types of environmental quality standards (EQSs, often referred to as soil quality standards [SQSs] for soils) to protect the environment and human health, but there are many more ways to set and implement a standard than legally binding limits that are introduced through direct regulation. However, even the softer approaches entail the use of a numerical standard that must have a sound basis in science. 

These environmentally regulated substances cannot dissolve in water, etc. as long as products such as a computer are in use. These substances may dissolve in water after the products that include them are discarded. Therefore, leaching tests are provided by laws to determine whether these products may be discarded or not. If the results of the leaching tests for these products are beyond the environmental quality standards (EQSs), these products must be discarded in a final disposal site where effluent cannot leak out. Disposal of wastes to a final disposal site is very expensive. To begin with, it is very difficult to secure the last disposal ground. 

In the case that materials and wasted material are used on land, dissolved concentrations must be below the environmental quality standards (EQSs) for soil. Because these materials may pollute soil, the use and the disposal of them on an area of land is judged from the EQSs for soil. These EQSs for soil are the same as for groundwater in Japan. In the case that materials are disposed of at sea, dissolved concentrations must be below the EQSs for seawater by the marine pollution prevention law. These EQSs are the criteria to determine whether waste is to be disposed of at sea or not.

The WFD, so far, has identified 33 priority hazardous pollutants (PHS), for which Environmental Quality Standards (EQS) have been set. To some extent, these EQS can be met through the establishment of emission control measures. These PHS may originate from several different sources and activities. The main sources of toxic substances to water bodies in Europe may be categorised as agriculture, sewage treatment plants, urban runoff, industry, contaminated lake/ river sediment, soils and landfills. Input via atmospheric transport and deposition has also been identified as an important source both far from and close to source areas. Many of the PS are today banned in Europe, but due to their persistence they are still present in the environment [30]. 

European eco-labeling of paper products, and in the existing European eco-labeling for cleaners under Regulation 1980/2000/EC. In addition, the EU Commission made further recommendations on risk reduction measures for EDTA. First, it asked EU Member States to establish Environmental Quality Standards (EQS) for EDTA, and the national pollution reduction measures to achieve those EQS in 2015 should be included in the river basin management plans in line with the provisions of Directive 2000/60/EC. Second, EU Member States should specify in IPPC permits measures on EDTA to operate to BAT by October 2007, taking into account local circumstances. Further, as BAT is developed, this should be incorporated into the permits. 

A balanced, comprehensive overview of Environmental Quality Standards (EQS), Derivation and Use of Environmental Qiiality and Human Health Standardsfor Chemical Substances in Water and Soil addresses the selection and prioritization of substances for standard derivation. With integrated content and up-to-date information on assessment of regulations that affect the derivation and use of EQS, it examines the derivation of these standards and their implementation to protect human health and the environment.

The principle mattix for assessing compliance with respect to Environmental Quality Standards (EQS) for priority substances is whole water or for metals, the liquid fraction obtained by filtration of the whole water sample. Whole water is a synonym for the original water sample and shall mean that suspended particulate matter (SPM) and the liquid phase have not been separated. 

According to the proposal for a Directive on environmental quality standards, EQS are expressed as total concentrations in the whole water sample, except for cadmium, lead, mercury and nickel. In the case of metals, the EQS refers to the dissolved concentration measured in the liquid fraction of a water sample obtained by filnation through a 0.45 pm filter. 

Status assessment of groundwater bodies asks for Environmental Quality Standards (EQS). With respect to the variability of natural hydrogeological settings and the resulting hydrogeochemical composition of groundwater, the GWD indicates that groundwater threshold values are quality standaids that are not set at a European level but by Member States at the most appropriate scale. 

The European Water Framework Directive (WFD) so far does not consider sediment quality and quantity as a major issue (Forstner and Owens, 2007). Objections against compliance monitoring for sediment, based on Environmental Quality Standards (EQS) for sediment, were caused by analytical limitations and anticipated costs involved in... 

Knowledge of the measurement uncertainty, together with the value of the limit of quantification (LOQ) (and limit of detection (LOD) ) is the basis for checking compliance with Environmental Quality Standards (EQS) and assessment of fitness for purpose of the data against the predefined objectives of the monitoring programme. 

Europe issued 18 black list substances daughter directives. These include an environmental quality standard (EQS) that the surface water must meet. Regarding the other dangerous substances, the Member States were compelled to draw up reduction programs. The set-up of the reduction programs did not occur until many years later. 

On 23 October 2000, the Directive 2000/60/EC of the European Parliament and of the Council establishing a framework for the Community action in the field of water policy or, in short, the EU Water Framework Directive (or even shorter the WFD) was adopted. There is a list of so-called priority substances within WFD. For substances on the list of priority substances an Environmental Quality Standard (EQS) have to be developed. The EQS sets the limit on the concentrations allowed in EU water bodies. Three active substances (ethinylestradiol, estradiol, and diclofenac) were included on the so-called Watch List in 2013 to be further evaluated for a potential future inclusion on the List of Priority Substances. 

Action levels, which are more likely to be set for the lifetime of the facility, are typically based on environmental quality standards (EQS), possibly with some variation to reflect the site-specific baseline conditions.

According to a proposal of 21 June 2007 for a Directive of the European Parliament and of the Council on environmental quality standards in the field of water policy and amending Directive 2000/60/EC, Member States may opt to apply EQS for sediment and/or biota instead of those laid down in Annex I, Part A, in certain categories of surface waters, (for the actual state of discussions, see Foerstner, 2008)...
