Assessment of Potential Health Hazards During Emission of Hydrogen Sulphide from the Mine Exploiting Copper Ore Deposit - Case Study.

Aim: The aim of this study was to determine hydrogen sulphide concentration emitted from the mine extracting copper ore, to evaluate potential adverse health effects to the population living in four selected villages surrounding the exhaust shaft.

Materials: Maximum measured concentration of hydrogen sulphide in the emitter is 286 µg/m³. Maximum emission calculated from the results of determinations of concentrations in the emitter is 0.

[Predictive models for the assessment of occupational exposure to chemicals: a new challenge for employers].

Employers are obliged to carry out and document the risk associated with the use of chemical substances. The best but the most expensive method is to measure workplace concentrations of chemicals. At present no "measureless" method for risk assessment is available in Poland, but predictive models for such assessments have been developed in some countries.

[Evaluation of methods for monitoring air concentrations of hydrogen sulfide].

The development of different branches of industry and a growing fossil fuels minming results in a considerable emission of by-products. Major air pollutants are: CO, CO2, SO2, SO3, H2S, nitrogen oxides, as well as compounds of an organic arigin. The main aspects of this paper is to review and evaluate methods used for monitoring of hydrogen sulfide in the air.

Occupational exposure to dusts and risk of renal cell carcinoma.

Background: Occupational exposures to dusts have generally been examined in relation to cancers of the respiratory system and have rarely been examined in relation to other cancers, such as renal cell carcinoma (RCC). Although previous epidemiological studies, though few, have shown certain dusts, such as asbestos, to increase renal cancer risk, the potential for other occupational dust exposures to cause kidney damage and/or cancer may exist. We investigated whether asbestos, as well as 20 other occupational dust exposures, were associated with RCC risk in a large European, multi-center, hospital-based renal case-control study.

Renal cancer risk and occupational exposure to polycyclic aromatic hydrocarbons and plastics.

Objective: To investigate whether occupational exposure to polycyclic aromatic hydrocarbons and certain plastic monomers increased renal cell carcinoma (RCC) risk.

Methods: Unconditional logistic regression was used to calculate RCC risk in relation to exposure.

Results: No association between RCC risk and having ever been occupationally exposed to any polycyclic aromatic hydrocarbons or plastics was observed.
