Organic Chemistry Testing

​​​​​AST provides an extensive NATA accredited chemical testing service in Organic Chemistry for waters, soils & solids, filters and biota.

Analyses covered by the Organic Section include:

  • Waste water bulk properties (BOD, COD, Oil & Grease) – A black labelled plastic bottle is required for BOD. A glass 1L bottle is required for Oil & Grease,

  • Herbicides, insecticides and pesticides, with now over 200 different compounds available with 58 targeted on our ultra low level method, and our pesticide suites ever increasing in scope. 

  • Petroleum Hydrocarbons (including TRH, vTRH, BTEXN, TPH), with or without silica clean-up

  • Polycyclic Aromatic Hydrocarbons (PAH) - AST offers USEPA priority suite (15 compounds)

  • Polychlorinated biphenyls (PCBs) - non-biodegradable remnants of formerly used coolants and heat transfer fluids

  • Tributyltin, Biocides & Anticoagulants,

  • Volatile Organic Compounds (VOCs) - now over 60 analytes available including trihalomethanes, halo acetic acids, formaldehyde, acetone, alcohols, and Bromoform 

  • Perfluorinated Compounds- PFOA, PFOS and other perfluorinated compounds. Common places where PFCs can be found are in formerly used refrigerants, fluoro surfactants, and fire-fighting foam

  • Antibiotic residue including Oxytetracycline (OTC) and Florfenicol

  • Phenols

  • Cannabinoids in hemp plants and hemp-based food products

  • Algal Toxins and Cyanotoxins such as Microcystins, Anatoxin-A, and Cylinderospermopsin

  • Shellfish Biotoxins including Brevetoxins​ 

  • Bromoform in seaweed and livestock feed 

  • Sewage tracers - Sterols, caffeine, and other pharmaceutical tracers

  • Acrylamide,

  • Nitrosamines,

  • Taste & Odour compounds (e.g. Geosmin, 2-MIB), and

  • General GC-MS / LC-MS screens for identifying unknowns.

Please contact the laboratory for assistance with selecting analyses and bottle types before sampling.

Typical scenarios where these types of tests may be useful include:

  • Waste water compliance monitoring

  • Contaminated site assessment,

  • Drinking water disinfection bi-products,

  • Herbicide & pesticide residue from spray drift or runoff,​

  • Landfill classification and leachate,​

  • Fire incident response,

  • Spill incident involving fuel or pesticide,

  • Shellfish biotoxin compliance monitoring

  • THC and CBD industry standard compliance

  • Air monitoring stations, and

  • Boat slipways and antifouling sites.

  • Research and Development projects
