Data quality oriented procedure, for detailed mapping of heavy metals in urban topsoil as an approach to human health risk assessment

2021

Abstract Urban soils' health is important to the community because of the soils' potential use for recreational activities. A data quality-oriented approach to sampling design is proposed for performing soil representative surveys that gives support to defensible and statistically-based decisions. Krowoderski park in Cracow (Poland) was selected as a study case to investigate heavy metals (HMs) accumulation and to assess human risk exposure according to simulated scenarios. Statistical power was computed for optimizing the number of samples to compare HMs concentration against legal upper tolerance levels (LUTL). The samples' location was iteratively designed as random spatial distribution …

Anthropogenic Soils and Soil Security: environmetal and economic consideration.

2017

Since ancient times Man and Soil have experienced interwoven links. Nowadays soil scientists continue to stress such links highlighting the importance of soil to provide man’s growing demand for food, water and energy, and also the soil’s importance in providing ecosystem services that affect climate change, human health and biodiversity. In soil management for agricultural purposes, pedotechniques to tailor soils suitable for table grapes cultivation in large-scale farming are used to get substantial financial returns. However farmers, in tailoring soils for high income crops, frequently do not take into account the fundamental objective of the pedotechnique, i. e. to meet the needs of man…

Stapedotomia V.S. Stapedectomia: nostra esperienza

2013

RAZIONALE La chirurgia della staffa ha visto negli ultimi anni molte innovazioni nel trattamento chirurgico dell'otosclerosi. In particolare, la stapedectomia è stata sostituita sempre più dalla stapedotomia prima con metodo classico e successivamente con metodica invertita, in quanto si ritiene che tali varianti chirurgiche consentano una maggiore riduzione del gap tra via ossea e via aerea per le alte frequenze, una migliore discriminazione vocale oltre che minori complicanze intra e post operatorie. Lo scopo del presente studio è stato quello di confrontare i risultati della stapedotomia con la stapedectomia nei pazienti affetti da otosclerosi e in particolare il miglior recupero uditivo…

An assessment of the Beerkan method for determining the hydraulic properties of a sandy loam soil

2014

Abstract Establishing the ability of the Beerkan Estimation of Soil Transfer parameters (BEST) procedure to reproduce soil properties is necessary for specific soil types. In this investigation, the BEST predictions for a sandy loam soil were compared with water retention data obtained by a standard laboratory method and with the saturated soil hydraulic conductivity, K s , obtained by both the Wu et al. (1999) method, applied to the BEST infiltration data, and the Simplified Falling Head (SFH) technique. When the original BEST-slope algorithm with the infiltration constants fixed at β = 1.9 and γ = 0.79 was applied, the agreement between the predicted and the measured retention data was sa…

A test of the Beerkan Estimation of Soil Transfer parameters (BEST) procedure

2014

Abstract The Beerkan Estimation of Soil Transfer parameters (BEST) procedure is attractive for a simple soil hydraulic characterization but testing the ability of this procedure to estimate soil properties is necessary. The BEST predictions were compared with soil water retention and hydraulic conductivity data measured in the laboratory and the field, respectively, at ten Sicilian field sites. Provided that BEST yielded physically possible scale parameters of the soil characteristic curves in most of the four replicated infiltration runs at a site, the measured water retention was satisfactorily predicted (i.e., not statistically significant differences between measurements and predictions…
