The presence of plastic waste is increasingly
evident on the beaches of Grand-Bassam, a UNESCO
World Heritage Site. This state of affairs calls for
diagnostic studies. Thus, the objective of this study was
to monitor plastic waste on the beaches of GrandBassam according to the four (04) climatic seasons of the
area. To this end, three (03) sites were defined on the
coast of Grand-Bassam for the monitoring of this plastic
waste. Subsequently, from March 2022 to October 2022,
eight (08) sampling campaigns including two (02) per
season, were conducted on a transect of 25 meters from
each site. The results of the surveys on the beaches of
Grand-Bassam indicate that the quantities of plastic
waste vary from 2.67 kg (Site 2, Long Dry Season) to 9.8
kg (Site 3, Short Dry Season) for a transect of 25 meters.
It appears that the composition of these plastics is largely
dominated by polypropylene (PP) with 33.35% and low
density polyethylene (LDPE) with 23.43% of the total
quantity of plastic waste collected on the three (03) sites.
The results of the test of variability (discriminant
analysis) and statistical analysis (ANOVA test) indicate
variability from one range to another and from one
season to another.
