Developed in the 1940’s, Organochlorine Pesticides were phased out in the early 1980’s. These pesticides are very persistent in soil, and residues can still be detected. Organochlorine pesticides include DDT, DDD and DDE, which have been banned from use.
ChemCentre offers the Organochlorine Pesticide (OCP) Suite in Soil (O100SL-OC) to test for a number of pesticides listed below:
Samples about 200-250 gms should be collected in a clean glass container. We recommend collecting the top surface soil and exclude any rocks, twigs etc. If you have a large area please collect from multiple areas and combine the soil to provide a representative sample of the area.
Please see our Sample container guide. Sample containers can be obtained free of charge from ChemCentre.
Submission times: Monday to Friday 8:30am - 4:30pm
Results and Turnaround Time
Please allow ten working days for results.
Cost for the Organochlorine Pesticide (OCP) Suite in Soil is $133.10 (including GST) per sample. Each submission also incurs a once off administration fee of $44.00 (including GST). (**ChemCentre's minimum charge of $220.00 (including GST) is waived for the OCP Suite in Soil test.)
Please note to avoid delays in sample analysis, prepayment must be paid at the time of sample submission.
For other analyses (for example, heavy metals such as mercury, lead etc) specific sampling requirements may be needed. Please discuss this with a ChemCentre scientist prior to collection of your sample. Please contact us today to discuss your requirements.

Organophosphate pesticides replaced organochlorine pesticides (above) and were used mostly to control insect populations. They are less persistent than organochlorine pesticides and are more easily broken down in the environment and the metabolism of mammals and insects.
Organonitrogen herbicides, or triazines, were originally developed in the 1950’s and are still in use today.
Synthetic pyrethroids are commonly used in household insect sprays. They are easily broken down by the human metabolism but have a fast reaction on the nervous systems of insects.
Glyphosate is a weed killer commonly found in many popular brands such as Round Up®, Zero®, Weedmaster Duo®, Contact®, Strike®, No Grow® and Trounce®. It is non-specific, meaning that it will be toxic to any plant with enough foliage. Glyphosate is very difficult, but not impossible, to analyse in the laboratory because it binds strongly to soil particles.
