THE ACUTE EFFECTS OF EMPIRE MIX CRUDE OIL ON ENZYMES IN OYSTERS, SHRIMP AND MULLET

ABSTRACT Crude oil spilled in an estuarine marine environment caused short term, acute effects on salt marsh plants. Drastic changes in both diversity and numbers in the fish population were observed immediately after the spill. Initially zooplankton populations dropped, accompanied by phytoplankton blooms. As the oil dissipated, the zooplankton population increased rapidly. Long-term effects on fauna and flora were being studied. Migration of the oil via benthic animals and tidal percolations was observed as much as 42 cm beneath the sediment surface. The sediments acted as an organic sink preserving the crude oil. Gas chromatographic analyses of sediment core sections indicate slow degradation of the crude oil with loss only of the lower molecular weight hydrocarbons after twelve months.

Plot Design

The growth of three mangrove species seedlings,Bruguiera gymnorrhiza, Rhizophora apiculataand Ceriops decandra in sediments contaminated by crude oil. Thisresearchwas designed to evaluate the acute effects of crude oil on the growth and survival performance of mangrove seedling in 4-week field experiment. Three treatments(sub plot) were compared with the control (no oil added) usingi.e. 100 ml, 120 ml and 140 ml crude oil applied once, in a split-plot design with nine replicates. The result showed the extent of survival has maximum for B. gymnorrhiza while it was minimum for C. decandra. The growth of mangrove seedlings was decrease with higher concentrations of crude oil. Stem height of B. gymnorrhiza seedling higher than R. apiculata and C. decandra.We observed, severe damage in the epidermis and the cortex at the root of all three types of mangrove seedlings when crude oil applied at 140 ml.
