  • A viewpoint on small-scale gold mining in Ghana: a regulatory perspective on current practices, mercury use and the UNIDO and EU projects

    This paper opens the special issue by providing an overview of small-scale gold mining in Ghana. Furthermore, it highlights the sector's mercury pollution problem, and describes two important interventions – projects funded by UN and EU – recently made to address the problem. Despite having considerable shortcomings, these projects have laid important groundwork for a comprehensive mercury ...

  • Removal of contaminants from industrial wastewater through various non-conventional technologies: a review

    It is difficult to separate industrial growth from environmental pollution but it can be minimised through cost-effective approaches of pollution abatement. To reach the full objectives of zero pollution, adoption of alternative technologies which suit the situation of low capital availability, minimum man-power and limited energy consumption are necessary. Adsorption through agricultural ...

  • Smelter gas cleaning one vessel from the quench to the drying tower

    Base metals such as zinc, lead and copper are all found in nature bound with sulphur as sulphite minerals: sphalerite (ZnS), galena (PbS), several copper minerals, silver (found as acanthite Ag2S), and, along with other precious metals. Processing of the metals invariably leads to sulphur dioxide (SO2) formation. Other metal processing, such as aluminum from bauxite ore [Al(OH)3] which contains ...

  • Total solution: Gas and particulate analysis in Cement industry

    Cement plants are increasingly required to install continuous emission monitoring systems (CEMS). While these represent a significant financial outlay, a range of other factors also need to be considered when selecting a suitable CEMS. To the inexperienced, selecting a suitable CEM can mistakenly be considered as simply ensuring that the applicable national regulations (eg MACT in the USA, ...

  • Superfund Remediation: The Key to Land Reuse Case Study

    The technology is ready and, with state and federal tax credits waiting, the economics look better than ever: New Jersey, one of the first states to be industrialized, finds itself plagued with the contaminated aftermath of pre-EPA industries: soil contamination. From superfund sites to the gas station whose underground storage tank has been oozing for the last 20 years, every ...

  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Costs of air pollution from European industrial facilities 2008-2012

    In 2011, the European Environment Agency (EEA) published a first assessment of the costs of air pollution caused by European industrial facilities. The report Revealing the costs of air pollution from industrial facilities in Europe (EEA, 2011) applied a simplified modelling approach to assess the damage costs to health and the environment in 2009, caused by pollutant emissions from industrial ...

  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Monitoring Environmental Quality

    ' In order to determine the effectiveness of actions to improve environmental quality it is necessary to be able to measure relevant environmental parameters at a level of detail which is accurate enough to distinguish the anticipated changes. However, the establishment and maintenance of monitoring systems is time-consuming and expensive and therefore the scale of such systems needs to be kept ...

  • Why high temperature combustion of landfill gas?

    Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas. With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental ...
