The concentrations of eleven (11) polyaromatic hydrocarbons (PAHs) and total hydrocarbons (THC)
were investigated in the water, sediment,
Chrysichthys nigrodigitatus
and
Macrobrachium macrobrachion
from
Badagry Creek and Ologe Lagoon in Lagos, Nigeria using EPA and Gas Chromatography (GC) methods. All the
samples(except water measured in mg/l) were measured in μg/g. PAHs were not significantly different(p>0.05)across
the two stations and were within WHO recommended limit.The highest concentration of THC from Badagry Creek
was recorded in
M. macrobrachion (219.565±171.891 μg/g) and this value exceeded WHO recommended limit.
Similarly, the highest THC (211.565±127.923 μg/g) recorded in
M .macrobrachion at Ologe Lagoon was above WHO
limit. The study has shown that the polyaromatic hydrocarbons were below the risk level, which indicated no risk status
from the consumption of the fish species studied. However,
C. nigrodigitatus and
M. macrobrachion studied from these
water bodies are highly contaminated with THC. Therefore, persistent monitoring and strict adherence to responsible
waste discharge should be upheld by all industries near these waters in order to avoid deleterious effects on the biota
as well as ensuring safety of the consumers.
