Dustfall Monitoring
Services
Gondwana is an ISO/IEC 17025:2017 SANAS Accredited Laboratory for
Environmental Analysis for dustfall monitoring. The accreditation is for the ASTM
D1739 standard method for collection and analysis of dustfall, which is the method
prescribed under the NEM:AQA National Dust Control Regulations of 2013 (NDCR).
According to the NDCR "dust (or settleable particulate matter)" means any material composed of particles small enough to pass through a 1 mm screen and large enough to settle by virtue of their weight into the sampling container from the ambient air; and "dustfall" means the deposition of dust.
Our SANAS accreditation covers both field work and laboratory analysis.
Gondwana has provided dustfall services to mines, power stations and numerous industries.
Dustfall gravimetric analysis
Dustfall gravimetric analysis
Dustfall gravimetric analysis of both soluble and insoluble components.
Dustfall chemical Analysis
Dustfall chemical Analysis
IF you want to understand where the dustfall is coming from, you may want to do chemical analysis on the particulate matter (PM) that has fallen into the sampler. Gondwana can assist by submitting the filter with the (PM) to a SANAS accredited laboratory to undertake this analsysis.
