Workers in many sectors are exposed to a number of chemicals by inhalation, ingestion or skin. This exposure has short or long term harmful effects on human health. Short-term exposures include poisoning, burning of the skin or eyes, irritation and some allergic reactions.

Long-term exposures are cancer, reproductive problems and neurotoxic effects. In general, the health effects of exposure to chemicals vary depending on the exposure intensity, ie dose or concentration of exposure, frequency, duration of exposure, and toxicological nature of the substance in question.

Some chemicals are clearly dangerous, even at very low concentrations and short exposure. Some are dangerous when exposed to very high concentrations and for a long time.

In working environments where chemicals are used in production, health inspections should be carried out within the framework of the relevant legal regulations and material safety data sheets of these chemicals should be kept in terms of chemical exposure. Businesses have to know the health risks and exposure levels related to chemicals and take the necessary precautions in advance. In addition, these inspections should be repeated at regular intervals.

Volatile organic matter (VOC) measurements and personal VOC exposure measurements are carried out by advanced laboratories to determine the risk of chemical exposure. Businesses are obliged to carry out risk assessment studies and to monitor the health and safety of employees working in safety and health risky jobs.

Appropriate methods should be used for environmental measurements and health surveillance in chemical enterprises. Enterprises are obliged to carry out measurement, test, analysis and evaluation studies in order to determine the risks of exposure to chemicals in the workplace in terms of occupational health and safety.

The methods and standards published by domestic and foreign organizations are followed in chemical laboratory exposure measurements performed in advanced laboratories.
