AI Article Synopsis

  • A pilot survey of 89 houses in Cyprus revealed an average radon concentration of about 7 Bq m-3, with most homes well below the concerning levels.
  • Four houses exceeded 30 Bq m-3, with the highest reading at 78 Bq m-3, which is relatively low compared to other countries.
  • Radon levels in homes vary significantly based on local geology, being highest in houses built on Chalk formations and lowest in those built on Olivine Basalt.

Article Abstract

Studies from a pilot survey in 89 houses in Cyprus show that the arithmetic mean for the housing stock is about 7 Bq m-3 and the annual effective dose equivalent to the population from radon progeny is < 330 microSv y-1. Four houses have values > 30 Bq m-3, corresponding to two standard deviations from the mean value. The highest value recorded was 78 Bq m-3. These results are considerably lower than those of other countries reported in the literature. Radon concentrations in houses is correlated to the local geology. The highest concentrations are in houses built on Chalk formations with an average value of 9.29 Bq m-3 (standard deviation 19.69 Bq m-3). The lowest concentrations are in houses built on Olivine Basalt formations with an average value of 0.50 Bq m-3 (standard deviation 0.80 Bq m-3).

The World Health Organization has identified multidrug-resistant bacteria as a serious global health threat. Gram-negative bacteria are particularly prone to antibiotic resistance, and their high rate of antibiotic resistance has been suggested to be related to the complex structure of their cell membrane. The outer membrane of Gram-negative bacteria contains lipopolysaccharides that protect the bacteria against threats such as antibiotics, while the inner membrane houses 20-30% of the bacterial cellular proteins.

During the harvest of Ilex paraguariensis, approximately 2-5 tons per hectare of thick stems are left on the soil surface. The outer portion of these stems, referred to as the coproduct, constitutes 30% of the total residue mass. Although this coproduct has been partially characterized in terms of its phytochemical profile, its technological applications remain unexplored.

Background: Air pollution is associated with poor asthma outcomes in children. However, most studies focus on ambient or indoor monitor pollution levels. Few studies evaluate breathing zone exposures, which may be more consequential for asthma outcomes.

The increasing demand for natural alternatives to synthetic fungicides has prompted research into natural products like essential oils for postharvest disease management. This study investigated the antifungal, antioxidant, cytotoxic, and genotoxic potential of essential oil mixtures derived from oregano, rosemary, and mint against Penicillium digitatum, the predominant fungal pathogen causing green mold in orange fruits.

Bone damages in laying hens are of great concern in poultry farming. Besides various risk factors like housing systems or nutrient supply during egg production, it has often been hypothesized that genetically high-performing laying hens may be more prone to bone damages. The relevance of dietary support during the rearing period of pullets for optimal bone development has been little addressed so far.
