pH, salinity, EC and TDS were measured in the field using a portable pH meter (Hanna, pH 211), microprocessor salinity meter and EC/TDS meter (Hanna, H1-9635).
On-site measurement of the wastewater like temperature, pH and DO were carried out at the site in the tannery environmental quality control laboratory using a portable pH meter (Wagtech International N374, M128/03IM, USA) and DO meter (Hach P/N HQ30d, Loveland. CO, USA).
Temperature and pH measurements were taken using a portable pH meter (Oakton Waterproof PC Tester 35 Multi-parameter pH Meter, Oakton Instruments, IL) within a few minutes after sample collection.
Random blood glucose: was assessed from fingertip blood, at the time of collecting the blood samples, using a portable glucose meter (Accu-Check Advantage – Roche).
The pH of the water samples was measured using a portable pH meter in the field.
Immediately after sampling, pH and electrical conductivity (EC) were measured in the field using a portable pH meter.
Water temperature and dissolved oxygen were measured in site using a portable oxygen meter (Jenway, London, UK).
Immediately after sampling, pH, temperature and EC were measured in the field using a portable pH meter.
The pH values were measured in the field using a portable pH meter (multiparameter PCS Tester series 35).
