Opis:
Playgrounds and sandpits (small architecture objects according to the Construction Law) are subject to meticulous supervision, both at the design stage and subsequent status checks of the objects. One of the requirements arising from the need to protect playgrounds from animals is the necessity for fencing the object (Regulation of 31 December 2002 On Safety and Hygiene in Public and Private Schools and Institutions; Polish Standard PN-EN 1176 Playground equipment and surfacing). Does fencing playgrounds really reduce contamination of sand? To verify this hypothesis, the studies have been conducted on the residential areas’ sandpits, both fence secured and unsecured, located in close proximity to one another. The aim of the study was to evaluate the effectiveness of fences and nets as protection from microbial and parasite contamination of sandpits, mainly due to the access of animals to them. For several seasons of spring and sum-mer the sand was examined in terms of the total number of heterotrophic bacteria and fungi (organic matter contamination of sand indicators) and for the presence of coliform bacteria (including Escherichia coli), bacteria of the Salmonella genus and the eggs of intestinal parasites. It can be concluded that fencing playgrounds affects sand pollution less with waste and plant material (as a consequence, it has been reported statistically significantly less heterotrophic bacteria and fungi in the fenced sandpits’ sand). Unfortunately, the fence does not eliminate the risks associated with sand pollution of coliform bacteria. Cats and birds, but also dogs, still have a continuous access to sand. Due to the repeatedly stated carelessness of children and their caregivers, gates left open to the playground do not constitute an obstacle for domestic and stray animals. Another source of sand pollution with intestinal pathogens can be a manner of carriage of new sand, as there is no legislation governing the issue of transport. It has been visually found that the sand has been transported in a vehicle used for waste disposal.

Opis:
Artificial beaches, i.e. places in the public sphere, are usually intended for recreation, located at water reservoirs, rivers, and their surface is naturally occurring or applied sand. The urban bathing beach located in Szczecin by the Deep lake has sand purchased and distributed on the beach by the Municipal Services Office in Szczecin (a few hundred ton). The beach is divided into sectors, a volleyball court is in one part, in the next section catering and sanitary facilities are located, and the remaining area is a place intended for sunbathing and playing games. The aim of the experiment was to assess the effects of different ways of using the beach on changes of microbiological properties of the sand. The tests were taken from the beach sand in May 2013 (first term examinations), and in September, after several months of use (the second term of examinations). The sand was collected near catering and sanitary sector (the first object) and from the area of the volleyball court (the second object), as well as the playground for children (the third object). The facilities were distanced from the shoreline of the lake by approx. 8 metres. The comparison included the number of heterotrophic bacteria, fungi and the detected presence of coliform bacteria, including Escherichia coli, bacteria of the genus Salmonella and eggs of intestinal parasites. In any of the objects, or the periods of time, eggs of intestinal parasites and bacteria of the genus Salmonella were detected. The presence of coliform bacteria including E. coli was found in the sand collected from a catering-sanitary zone, there was also the biggest number of bacteria and fungi. The number of heterotrophic bacteria and fungi was similar in samples of sand taken from the volleyball court and from the playground, in this sand there was no bacteria belonging to the E. coli species, although in several samples from the playground other bacteria belonging to the coliform genus were detected. To sum up, it is possible to state that the same sand used in various ways is gaining different microbiological characteristics. The values of the studied parameters differed significantly with regards to sand taken from the area of consumption, hygiene-sanitary activities and sand collected from the area of active leisure (the court and playground). These results indicate the need for a deliberate selection of location for sunbathing (children playing in the sand) away from the sites for culinary and sanitary purposes.
