Environmental VOC monitoring

SURVEY TYPE: ENVIRONMENTAL VOC MONITORING

DESCRIPTION & DETAILS: The survey will be conducted to quantify the levels of volatile organic chemicals (VOCs) at predetermined sampling points along the boundaries.

LEGISLATION

Department of Environmental Affairs and Tourism (DEAT) Guidelines

DEAT does not have any average monthly guideline limits for non-methane hydrocarbons. Thus use is made of the threshold limit values (TLV’s) as published by the American Conference for Governmental Industrial Hygienists (ACGIH). The guideline limit is taken as 1/50th for ordinary pollutants and 1/100th of the TLV for carcinogenic or suspected carcinogens.

SAMPLING PROCEDURE

The Radiello is the ambient method of choice for non-methane organic hydrocarbons. Sample collection is taken over a 30-day period.
