Abstract
The investigation of ecotoxicological effects of particulate matter and the
increasing interest in correlating chemical composition to biological impacts is
of paramount importance. A complete assessment of biological impacts will
require a broad look at the effects of human health and the terrestrial and aquatic
environments. The objective of this work was to assess the effects of various
sizes of particulates on aquatic organisms. Samples were collected from filters
and the filter contents were extracted with DCM using a Soxhlet extractor. Then
concentration DCM extracts were condensated to 2 ml by rotary evaporation and
each millilitre of extract was exchanged with 1 ml of DMSO and then diluted to
freshwater. The samples were then analyzed for their ecotoxicological properties
with Vibrio fischeri and bioassay. Five consecutive dilutions of the sample were
tested in order to determine the EC50 values as a result of different size of
particulates.
Keywords: PM10, PM2.5, particulates, toxicity, bioassays.
1 Introduction
The knowledge of the distribution of airborne particulate matter (PM) into size
fractions has become an increasing area of focus during the examination of the
