Organics

We offer a wide range of biological monitoring for organic compounds including:

 

Isocyanates


Solvents

Although blood samples have been traditionally used for solvent exposure assessment, HSL (in line with HSE recommendations) prefers to offer non-invasive sampling where possible.  Urine sampling is available for a number of solvents including benzene, dichloromethane, ethylbenzene, MEK (2-butanone), MIBK (4-methyl-2-pentanone), styrene, toluene, xylene.  Where highlighted, there are UK guidance values available.

Benzene - HSL has undeertaken a literature review for the Energy Institute.  We also have a case study on benzene exposure during tunneling work.

Where a number of solvents are used, a solvent screen may be more appropriate.  This is possible using the HSL-developed Bio-VOC breath sampler.

Pesticides

Organophosphorous pesticides

Synthetic Pyrethroids are widely used in agriculture, horticulture and forestry.  We offer specific urine metabolite analysis for permethrin, cyperthrin and deltamethrin and a generic metabolite (3-phenoxybenzoic acid) for other synthetic pyrethroids.  These are available on a quarterly basis - see the price list for details.

NEW! Glyphosate is one of the most widely used herbicides around the world. Recently there has been some debate about the carcinogenic potential of glyphosate ( IARCEFSA); these discussions are on-going.  In the meantime, HSL can now offer a straightforward urine test to evaluate workers' exposure to glyphosate and help to ensure that exposures are controlled.  Contact us for further details.

Other pesticides that HSL offers urine analysis for include captan, chlormequat, bendiocarb, dithiocarbamates, pirimicarb, dinoseb and penconazole.  These are available on a bespoke basis - see the price list for details.

 

Polycyclic aromatic hydrocarbons

Polycyclic aromatic hydrocarbons (PAHs) are by-products of combustion.  There are a large number of compounds that are classified as PAHs; some, such as benzo(a)pyrene, are carcinogenic.  HSL has published research showing that pyrene is a good generic marker of PAH exposure and that urinary 1-hydroxypyrene is a suitable biomarker.  HSE has set a UK guidance value for 1-hydroxypyrene in urine (4 µmol/mol creatinine).
