Air Pollution - Monitoring Particulates
An effective monitoring strategy allows the impact from particulate to be assessed and controlled.
Clean air is an essential requirement for the health and wellbeing of both the human race and the environment we live in, but achieving it is a constant battle with air pollution. According to the World Health Organisation (WHO), more than two million premature deaths each year can be attributed to the effects of urban outdoor and indoor air pollution1, a shocking statistic indeed.

Environmental Monitoring Standards and Methods - Selection of standards for emission monitoring
With the increasing requirement for the installation of continuous emission monitoring systems (CEMS) it is important that capital investment is protected and that instrumentation gives reliable, meaningful and repeatable data. Fitting MCERTS-approved equipment is one element but it is extremely important that the system is verified. The verification process requires the use of standard reference methods to underpin the data.

Methods of Soil Analysis - A summary of some of the many methods of soil analysis
Soils are an extremely complex matrix to analyse, particularly on contaminated sites - the actual soil matrix can vary from a sand (silica) to limestone (calcium carbonate) to clay (complexed minerals), or a mixture of many. In addition to this, the range of contaminants varies from fairly innocuous construction materials to toxic gasworks waste to highly toxic pharmaceutical waste/ mercury/explosives, etc.

Firstly let’s look at the dictionary definition of a metal: An element which is shiny, malleable and ductile, is a good conductor of heat and electricity the atoms of which readily loose electrons to form positive ions (cations).

Premium Efficiency Wastewater Pumping - Optimising energy consumption and preventing blockages
There is no doubt that the pressures on a wastewater business have changed regardless of whether you are a publicly funded municipality, privately owned water company or a private operator of a wastewater collection system. We clearly see an increased focus on energy use with regard to cost and CO2 footprint, along with the demand to reduce the number of blockages and the associated risk of overflows.

Something Not To Be Sniffed At
People’s perception of odours is a subjective matter; what one person perceives to be a pleasant odour, someone else may find unpleasant or a nuisance, which makes it difficult to assess and mitigate smells that may constitute an environmental pollutant.
