BACKGROUND/AIMS:
Micro pollutants are one of the important environmental problems that can be found in wastewater at very low concentrations. Heavy metals in the micropollutant class are the most common and toxic substances found in wastewater. If exposure to heavy metals exceeds the concentration allowed by WHO, it can cause serious health problems.
MATERIALS AND METHODS:
In this study, our aim is to determine some heavy metal amounts of samples taken from hematology analyzer wastewater on 7 different days by ICPMS. Quantitative analysis of 10 different heavy metals was made with ICP-MS and the results were obtained in ppb. Statistically minimum-maximum, median and average values were obtained.
RESULTS:
Aluminium (135.9 μg/L), chromium (29.5 μg/L), manganese (41.8 μg/L), nickel (103.4 μg/L), copper (2776.1 μg/L), zinc (9662.9 μg/L), arsenic (1.3 μg/L), cadmium (0.2 μg/L) and lead (202 μg/L) were found. Vanadium was not found in any of the measurements. Aluminium, arsenic, chromium, and cadmium elements were below the micro-pollutant levels, while the amount of manganese and nickel elements were determined above the micropollutant levels. The amounts of copper, zinc, and lead elements, which have serious toxic effects on human and environmental health, were found much higher than the micro-pollutant levels.
CONCLUSION:
It is thought that it would be appropriate not to discharge the wastewater of the hemogram device directly into the groundwater, but to pass it through appropriate treatment systems beforehand.
