Aim: The main target of this investigation was focused on the searching for poisonous plants in gardens of nursery schools, and to assess the level of danger to children and awareness of teachers who ensure the safety of children during their stay in the nursery schools. Methods: The research was carried out in a total of 40 kindergarten gardens in the Rakovník district. Field research consisted in performing photo documentation, description and identification of plants present in the gardens of kindergartens, or in a brief description of the location of poisonous plants in relation to play elements or edible plants. A questionnaire survey was also...

Hygiena 2020, 65(2):48-51 | DOI: 10.21101/hygiena.a1752  

Objectives: To evaluate the iodine content of milk from market sources in Prague. Methods: Using the Sandell-Kolthoff reaction, iodine was analyzed in 26 different types of milk (full-fat, semi-skimmed, skimmed, fresh and long life) from seven retail chains operating in Prague. Milk was supplied by eight dairies identified by the CZ registration number. Results: The mean ± standard deviation (range) iodine concentration in milk samples was 234 ± 56 (125-364) μg/L. This result is close to the recommended limit of 200 μg/L. Semi-skimmed milk had a statistically insignificantly higher (p = 0.085) iodine content of 250 ± 52 μg/L...

Biocides used for legionella prevention in hot water systems

Ivan Černý

Hygiena 2020, 65(2):52-55 | DOI: 10.21101/hygiena.a1744  

Objective: The objective of the paper was to verify the effects of several biocides used in the Czech Republic for prevention of legionella in hot water systems. Selected biocides were tested (sodium hypochlorite, chlorine dioxide, chlorites and chlorates) as well as compounds (DUOZON, SANOSIL). Method: A natural strain of Legionella pneumophila, sg 1, isolated during regular testing of warm water samples was used for testing. Because control strains lose some of their properties in storage they are inappropriate for this type of testing. The testing strain was exposed to varying concentrations of biocides in tap water for a 60 minute period to determine...

Psychosocial and socioeconomic factors contribute to the risk of developing cardiovascular diseases, with a worse clinical course and prognosis of cardiovascular disease. Stress plays an important role on several levels. It affects risk factors for cardiovascular diseases, the onset and development of atherosclerosis and can trigger a cardiovascular event. It modifies behaviour and lifestyle which in turn affect mental and physical health. The article focuses on issues of stress, the impact of stress on cardiovascular disease and points out how acute and chronic stress can influence developement of cardiovascular diseases in the light of epidemiological...

Strategic noise maps at the crossroads

Hygiena 2020, 65(2):63-70 | DOI: 10.21101/hygiena.a1750  

According to WHO findings, noise has become the second most serious environmental pollutant. In 2002, the European Commission issued Directive 2002/49/EC on the assessment and management of environmental noise, which became an important framework for the identification of noise in EU countries. This Directive describes the development of strategic noise maps and environmental noise action plans, which are carried out in regular five-year cycles. The Czech Republic has extensive experience in this area and the National Reference Laboratory for Environmental Noise participates in the work of a number of working groups of the European Commission, the...

Hygiena 2020, 65(2):71-75 | DOI: 10.21101/hygiena.a1754  

Discussed is a case of spoiled flavored bottled water, the ingestion of which by the consumer has led to need for treatment in hospital, probably due to an allergic reaction. The reason was the occurrence of mold and odorous substance 1,3-pentadiene. We describe in detail the method of investigation, the official control procedure of the public health protection authority and the mechanism of food spoilage.

Coronavirus and smoking

Eva Králíková

Hygiena 2020, 65(2):78-79 | DOI: 10.21101/hygiena.a1756  

Early publications on the characteristics of diagnosed patients with the new type of SARS CoV-19 coronavirus indicate a lower proportion of smokers compared to prevalence in the given populations, although smoking status is very rarely reported. Hospitalised smokers, on the other hand, have more severe disease progression than non-smokers and are at higher risk of death, particularly the complications in which smoking is involved, such as hypertension, diabetes mellitus, renal or cardiovascular failure. Also, the relationship of smoking with the ACE2 receptors is discussed. We do not know the possible misleading and confounding factors or the exact...
