Contamination load and distribution of contaminants is shown. Gaiasafe Passive Collectors have been used successfully to determine single compounds out of the contamination load. Furthermore the spreading and biodegradation of contaminants was monitored over a large area in Abidjan. Only a few days after the dumping the chemical waste from Probo Koala was detected in the surface water, after two weeks the waste was not longer detectable.
The use of Gaiasafe Passive Collectors supports environmental monitoring effectively by its unique integral sorption capability. Direct contact of PC with water offer a close and realistic view onto the contamination load.

The Gaiasafe Passive Collectors (PC) consist of a paper arrangement of different active sorption fibres. This PC’s are capable of collecting all organic compounds, heavy metals and metalloids and can be used in all environmental settings.
The PC’s are suited for surface and groundwater monitoring, with an effective collection time interval of 1 to 8 weeks, depending on the amount of present contaminations.
Application of PC yields the medium load contamination during the collecting time. Field use, handling and transfer of PC samples are very simple. After their use, the PC’s are dried and stored in suitable shipping containers. The low item weight of 2.7 grams enables easy shipment even from remote sites.
