A source from the Department of Natural Resources and Environment of Kien Giang province said that the agency had received the results of preliminary analysis of water samples analyzed CENTEMA Center for Applied Technology and Environmental Management related to the sea Mass production mentioned above.
Previously, three samples were transferred to this center for analysis to find the active ingredient that can kill fish mass.
As a result, there are 17 basic indicators in seawater and 2 indicators of pesticides are in the standard. Particularly surfactant indicators (indicators not in standard 10-MT: 2015 / BTNMT) are higher than normal.
In addition to the above three water samples, Kien Giang DONRE collected 7 samples of water for analysis at the laboratory of the Monitoring Center under the Department.
