Biomonitorring with Benthos
Benthos can indicates good and bad water conditions, it’s called biomonitorring. Benthos can be determined of biomonitorring by the stages of sampling and measurement based on biological as main parameters and physical-chemical in secondary parameters of a water body.All parameters interconnected each other.
First of all, one time water sampling for all measurement parameters. In addition, we must find out the sampling location what can be representative of water quality. The first parameters measured is physical parameters. The water is taken with water sampler, then packaged for physical-chemical analysis. Physical measurement are carried out at the sampling location. Physical parameters measured are temperature, pH, and turbidity.
After physical parameter measured, biological parameter can measured in sampling location. Biological parameter commonly measured benthos. Benthos is a benthic organisms and can be found in aquatic sediments. Benthos is taken with kick net or ponar dredge, then packaged for type identification. The identification using a book of benthos traits.
The last of biomonitoring is a chemical parameters. Packaged water that has been taken, in the chemical parameters analysis. Chemical parameters are usually in the laboratory. Chemical parameters measured are Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). In the laboratory, chemical analysis usually has a high level of complexity.
Biomonitorring with benthos needed some parameters measured. The measurement results in biomonitorring are compared with the regulations to determine the condition water. All parameters measured are continuous each other.
