Physical Activity of Working-Age People in View of Their Income Status.

Objective: The study examines relationships between physical activity levels and income status of working-age city residents.

Methods: The study was carried out in the years 2014 and 2015 in Wrocław, Poland. The study sample comprised 4332 participants (2276 women; 2056 men) aged 18 to 64 years.

Metal uptake by woodlice in urban soils.

This study evaluated the uptake of bioavailable metal (Cd, Cr, Cu, Fe, Pb and Zn) by woodlice (Isopoda) collected from public open spaces in urban areas of Renfrewshire, Central West Scotland, UK. The species Oniscus asellus and Porcellio scaber were collected at 13 different locations together with associated surface soil samples. Soils were subject to sequential extraction to evaluate metal availability and analyzed by ICP-AES and flame AAS for Cd, Cr, Cu, Fe, Pb and Zn concentrations.

The interaction of heavy metals with urban soils: sorption behaviour of Cd, Cu, Cr, Pb and Zn with a typical mixed brownfield deposit.

This study investigated the sorption characteristics and release of selected heavy metals (Cd, Cu, Cr, Pb and Zn) from a typical urban soil material from a derelict brownfield site in Western Scotland, UK. The study aimed to evaluate contaminant interactions with an urban substrate, comprising a mix of mineral soil and residue materials (e.g.
