Drinking Water ASTM Methods (2017)

ASTM has developed several LC/tandem mass spectrometry drinking water methods in partnership with the EPA.

  • D7598 Analysis for Thiodiglycol (LC/MS/MS)
  • D7599 Analysis for Ethanolamines (LC/MS/MS)
  • D7600 and D7645 Analysis for Carbamates (LC/MS/MS)

Oregon Cannabis Pesticides Spotlight height=

Oregon Cannabis Pesticides (2017)

The Oregon Health Association (OHA) has classified and submitted three prioritized groupings of residue cannabis pesticides:

   • Fungicides       • Pyrethroids       • Organophosphates

In June of 2015, a white paper titled “Pesticide Use on Cannabis” published by the Cannabis Safety Institute originally contained 188 active compounds. From the targeted 188 active compounds a working group with the OHA had numerous analytical laboratories study the toxicological effects and the historical natural application of each of the compounds for crop and human digestion. The results reduced the original number of targeted compounds. 59 pesticides were eventually approved and targeted. These 59 remain on the State of Oregon list. AccuStandard, Inc. offers three individual mixes of these 59 compounds.

Tetradecabromodiphenoxybenzene (TDBDPB) Spotlight (2016)

Tetradecabromodiphenoxybenzene (TDBDPB), a compound with a high molecular weight with 14 bromine atoms, was promoted as a compound with low rates of bioaccumulation and excellent thermal and photolytic stability. Studies show TDBDPB undergoes natural sunlight degradation. Recently, debromination products and various methoxylated debromiated TDBDPB have been found in gull eggs. We have synthesized and now provide a variety of hydroxylated and methoxylated, as well, polybrominated diphenoxybenzene degradation products as reference standard.

Chlorinated Diphenyl Ethers

Chlorinated Diphenyl Ethers (2016)

Polychlorinated diphenyl ethers (PCDPEs) resemble polychlorinated biphenyls (PCBs); and they exhibit physiochemical properties similar to the PCBs, dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs).

Phthalate Replacement Standards (2016)

Concern over enviromental and health-related factors associated with phthalates has led to restrictions of use in a wide array of products.  This has resulted in the plastics industry generating a variety of alternatives.

In response, AccuStandard has developed a phthalate replacement standards product line comprised of 42 compounds representing 18 chemical classes.

Halobenzoquinone Standards (disinfectant by-products) (2014)

Halobenzoquinones (HBQs) are disinfection by-products formed by reactions between disinfectants and organic matter in water.  HBQs likely exhibit carcinogenic properties due to their structural similarities with benzoquinone and related compounds.

Phosphate Flame Retardants (PFRs) (2014)

Organophosphate compounds (OPs) are high production volume chemicals.  They are utilized as flame retardants and plasticizers, antifoaming agents and additives not only in plastics, but in paints, lubricants and hydraulic fluids as well.  The chlorinated OP compounds like tris(2-chloroethyl) phosphate and tris(1,3-dichloro-2-propyl) phosphate are flame retardants used in both flexible and rigid polyurethane foam (e.g. furniture foam, thermal insulation), rubber, textile coatings, and home electronics.  OPs have been detected in indoor air and house dust, surface, ground, and even drinking water.  Ongoing toxicological studies have shown several toxic effects of these compounds, prompting the recognition of potential ecological and human health concerns of neurotoxin and carcinogenic nature.
