Hash marks: Hashish seizures compared by GC/MS

Date: Nov 15, 2013

Author: Steve Down

Different seizures of hashish can be linked to the same block by GC/MS analysis which compares the profiles of seven components, six cannabinoids and one hydrocarbon.

The decline in bees: Are pesticide surfactants to blame?

Date: Sep 2, 2013

Author: Steve Down

High levels of the trisiloxane components of pesticides have been measured in beeswax and pollen from beehives, suggesting that their effects on the health of bees should be examined in detail due to the global decline in honey bees.
