SMOC: ‘refinery emissions measured during August’

WILLEMSTAD - Measurements of the last month show that the Isla refinery standards for sulfur dioxide emissions have been exceeded considerably. This is according to SMOC’s environmental reports. The refinery also crossed the line with the emission of hydrogen sulphide (H2S).

The sulfur dioxide (SO2) is measured at Beth Chaim (Jewish cemetery). SMOC has upheld the standards of the WHO (World Health Organization) (ten-minute average 500 micrograms per cubic meter, 24-hour average 20 micrograms per cubic meter) for measuring sulfur dioxide. Below the measurement results.

"Unfortunately, no action was taken by the government of Curacao and The Hague and only a few substances are measured regularly," said SMOC in a statement. One of the substances is measured by hydrogen sulphide (H2S). The standard for hydrogen sulphide is 1 to 2 g per cubic meter. This standard was substantially exceeded last month according to the environmental reports. Below the measurement results.

Both sulfur dioxide (SO2) and hydrogen sulfide (H2S) are detrimental to human health and the environment. Sulphur dioxide is one of the most important aspects of air pollution and smog. Hydrogen sulfide produces not only odor but is also toxic. In small concentrations the substance can be recognized by the smell of rotten eggs, in higher concentrations it can be the cause the loss of consciousness and death. The International Chemical Safety Card (ICSC) reports that each contact with this substance should be avoided.
