Risks connected with the use of chemicals, risk assessment values of parameters of the workload related to them have been researched in this master’s paper. We have researched and analyzed physical load of the work, workload parameters – consumption of energy and quantity of breathing air, and impact of workload to the risks of air pollution, as chemicals and dust. Conclusive data have been obtained proving, that quantity of physical load of the work directly related to the risks caused by air pollution with chemicals and dusts. Connection of data between workload and risks caused by chemicals and dusts has been obtained. These connections can be applied for assessing the risks caused by chemicals and dusts taking into consideration the quantity of physical load of the work.
