Envirochem have recently visited a client based in Portsmouth to complete ammonia, amines and VOC emission analysis on three sets of air filters. They approached Envirochem because of occupational hygiene concerns from their colleagues complaining of headaches through the odour the filters were producing when in use. For the sampling, airbox pumps were set up for charcoal filter tubes to capture any VOC emissions and silica gel sorbent tube for amines. Any ammonia gas produced was captured using an impinger. The sampling took place during a normal run time for the filters and taken back to the lab to be analysed through IC and GC-MS.
The results from this study, along with the results from a previous emissions test can be used to determine if employees are exposed to high levels of harmful gases and whether extra measures need to be put in place to prevent exposure.

A school in Stafford has recently reopened after high levels of formaldehyde forced its closure back October 2015. Formaldehyde was initially detected after numerous pupils reported feeling unwell after discovery of the smell
Formaldehyde, which is found in materials used to make plywood and various types of insulation, is a colourless gas which has a strong odour. Exposure to formaldehyde can cause irritation to the nose, eyes and throat as well as being described as a carcinogenic substance by most health organisations.

Envirochem offers soil analysis for hydrocarbons, including total TPH (total petroleum hydrocarbons), speciated TPH (aliphatic/aromatic or banded), PAH (polyaromatic hydrocarbons) analysis and BTEX (benzene, toluene, ethyl benzene and xylene). We can also identify specific compounds of interest using GC-MS (gas chromatograph mass spectrometry).
The importance of soil analysis can be vital when dealing with contaminated land, as shown in this story from Canada

The proposed fracking in Wressle is set to use a technique known as duo frac. One of the involved stages is acidisation, this uses hydrofluoric acid (as well as other chemicals) to dissolve material collected at the drill head. The Environmental Agency has stated that this is the first time hydrofluoric acid has been used for onshore drilling. There are concerns that these chemicals, as well as hydrocarbons, could contaminate ground water and affect the neighboring steel production.

The development of unused land in Kearsley into a new cycle track was met with controversy as it emerged that the land is an old landfill site, contaminated with many toxic chemicals and materials including copper, zinc, arsenic, lead and asbestos.
Residents claim that those local to the area are aware of the dangers of the sites and that the land is best left alone. However a member of the council’s cabinet for the environment has stated that the land would only be developed after a contamination expert had visited the site to clean the site. He also pointed out that it is common practice to develop on old contaminated lands, after appropriate remediation.

Envirochem offer testing for many contaminants, if you would like to enquire please fill in the attached form.
Flammable gases, such as methane, are often found in and near to landfill sites due to the decomposition of waste and migration of gases though soil. Methane, specifically, is an odourless gas which is flammable and is an asphyxiant gas. Gases such as methane pose a risk to enclosed spaces such as under floor voids and workers in poorly ventilated areas, as well as a fire/explosion risk to landfill sites themselves.
Envirochem offers monitoring for many types of gas including methane, sulphur dioxide, hydrogen sulphide and nitrogen oxides. Envirochem also offers many other kinds of occupational hygiene analysis and monitoring.

Researchers from the University of California have developed a global map showing how the soil pH changes abruptly between wet and dry climates. The research revealed that in wet climates, soil pH is acidic whereas in dry climates it is alkaline. This change in pH happens suddenly and therefore any small changes in temperature can have significant effects upon land use, soil fertility etc.

Walton on the Naze Leisure Centre in Essex has temporarily closed some of their facilities due to the detection of legionella bacteria within the fitness room showers. Tests were carried out when a customer fell ill after using the showers in November.

Legionellosis is a collective term for diseases caused by legionella bacteria including the most serious legionnaires’ disease, as well as the similar but less serious conditions of Pontiac fever and Lochgoilhead fever.
The bacterium legionella pneumophila and related bacteria are common in natural water sources such as rivers, lakes and reservoirs, but usually in low numbers. They may also be found in purpose-built water systems such as cooling towers, evaporative condensers, hot and cold water systems and spa pools.
