Results of tests conducted on sea water and sediment samples taken at four locations from La Brea to Otaheite showed no correlation to a sample of COREXIT or liquid provided to the testing laboratory.
This update is contained in the latest media release from the Environmental Management Authority on the investigation into the Gulf of Paria fish kill.
The EMA adds that results of the testing of the sea water and sediment samples indicate that there was no COREXIT (the substance which has been purported as being one of the possible causes of the fish kill) at the sample locations, as no compounds matching COREXIT were found in the sediment and water samples taken.
It adds that the findings of the laboratory testing support the information shared in a joint press release from the EMA and Institute of Marine Affairs on July 21st which pointed to the likely cause of the fish kill being as a result of a fish dump of unwanted or spoilt catch, and not as a result of an oil spill, red tide or the presence of COREXIT.
However, in addition to the tests conducted by CARIRI confirming that no COREXIT was found at the sample locations, the EMA and IMA have been conducting further surveys/testing of samples in the area where dead fish have been observed.
These test results will be used to validate the findings of the ongoing investigation.
Concerning the fish samples sent to the Veterinary Diagnostic Laboratory, the pathology report reveals that “all body systems examined appeared grossly normal” with “no gross lesions” on the fish carcasses. Histopathology and parasitology reports are pending and further updates will be provided as they become available.
