• Description:
  The High Volume Small Surface Sampler (HVS3, CS-3, Inc.) collects representative samples of dust which can be analyzed for lead and pesticides. It has been used in recent pesticide exposure studies and was used this spring by NIOSH to collect house dust samples in a study of farm family exposure to pesticides and lead. The HSV3 is a modified vacuum cleaner with an attached cyclone. The flow rate and pressure drop at the nozzle can be adjusted so that sufficient air velocity is generated to life dust particles into the air stream. Criticism of the HSV3 is that it is difficult to obtain the proper flow rate and pressure drop during sample collection. Another criticism of the HVS3 is that when used on bare floors, the air exhausted from the vacuum blows any dust on the floor away from the collection nozzle. In attempt to improve the HVS3 we designed a separate chassis to hold the cyclone and nozzle so that it is no longer attached to the vacuum. The cyclone is then connected to the vacuum with a 12-foot tube. This design eliminates one of the steps currently needed to operate the HVS3, allows for a more consistent pressure drop and flow rate, and prevents dust from being blown away from the sample area by the vacuum motor. The chassis was successfully used recently in a study of farm families' pesticide and lead exposure. Operators reported that the flow rate and pressure drop were more easily maintained and they perceived that dust collection from bare floors was improved (although this was not evaluated quantitatively). The disadvantages to the chassis include the extra pieces of equipment that must be carried and the requirement that the operator has to be on his hands and knees when operating the equipment.
