Human and environmental health risks associated with eleven metal(loid)s evaluated in topsoil and wild mushrooms sampled from across Leicestershire, UK.

description: Anthropogenic discharge of metal(loid)s is adding to widespread pollution in urban and rural environments that may exceed limits for safe human and environmental health. The study objectives were to elucidate the presence, distribution, and quantification of eleven metal(loid)s, Be, V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd and Pb, that are of toxicological importance in topsoil and their bioaccumulation in wild mushrooms, used as biomonitors from parks across Leicestershire, UK. Moreover, the study assessed human, and ecological health risks to metal(loid) exposure from these sources. Topsoil and wild mushroom samples were collected from parks across Leicestershire. The samples were acid mineralised, followed by metal(loid) concentration evaluation using inductively coupled plasma mass spectrometry. Health risks from exposure to these metal(loid) sources were determined using established methodology. Mean concentrations of metal(loid) per kg dry topsoil from across Leicestershire were ranked: 418.19mg-Mn >119.02mg-Zn >99.29mg-Pb >69.48kg-Cr > 48.65mg-V > 35.45mg-Cu >32.60mg-Ni >5.94mg-As > 9.14mg-Co > 1.04mg-Be > 0.32mg-Cd, respectively. The mean concentrations of metal(loid) per kg dry wild mushrooms from across Leicestershire were ranked: 84.90mg-Zn >80.07mg-Cu >11.75mg-Mn > 2.72mg-Ni > 2.10mg-Pb >1.91mg-Cd > 0.86mg-Cr > 0.19mg-As > 0.09mgV > 0.03mg-Co, respectively. V, Co, Ni, Cu, Zn and Cd concentrations were found to be above their recommended soil screening values. However, individual metal(loid)s found in topsoil samples did not exceed their soil guideline values. However, the pollution load index indicated pollution concern across Leicestershire. Maximum allowed concentrations for Cu, Cd, Pb in wild mushroom were exceeded in samples from NW, NE, SW and SE Leicestershire. As(total) was exceeded in samples from NW Leicestershire. Metal(loid) exposure from topsoil from NW, NE, SW, SE, and rural Leicestershire, potentially harboured increased non-carcinogenic risks to …
