Recurrent discharges of non-petroleum substances from chemical tankers in Swedish marine Natura 2000 sites are against the aims of EU Directives.

The transport of non-petroleum substances such as vegetable oils, other bio-based oils and their refined products by chemical tankers is increasing worldwide. The majority of the non-petroleum substances carried by chemical tankers will have detrimental effects on the marine environment if accidentally spilled or discharged during tank washing procedures. Swedish Coast Guard aircrafts detected 233 discharges of floating non-petroleum substances in the Swedish territorial sea and Swedish Exclusive Economic Zone (EEZ) between 2020 and 2023.

Colonization with potentially pathogenic respiratory tract bacteria. A household study.

A group of 235 persons (180 adults and 55 children 0-15 years old) recorded symptoms of upper respiratory tract infection daily during two three-month periods (autumn 1986 and spring 1987). Samples for culture were taken from the nasopharynx and throat once during each period. Fifteen per cent of asymptomatic subjects harboured respiratory pathogens in the nasopharynx, as did 28% of those subjects with minor respiratory tract infections and 46% of those with more severe respiratory tract infections.
