Background levels of heavy metals in surficial sediments of the Gulf of Lions (NW Mediterranean): An approach based on 133Cs normalization and lead isotope measurements [PDF]

open access: yes, 2005
This paper presents an attempt to reach natural background levels of heavy metals in surficial sediments of the Gulf of Lions(NW Mediterranean). To correct for the grain-size effect, normalization procedures based on a clay mineral indicator element are ...

Pollution of potentially toxic metals in urban road dust in Dushanbe (Tajikistan) [PDF]

open access: yesE3S Web of Conferences, 2019
Heavy metal contamination in the road dust due to traffic in the capital city of Tajikistan was investigated. Concentrations of potentially toxic elements (Ba, Cu, Cd, Co, Cr, Pb, Ni, Zn and As) in particle size of 63 μm were analyzed.

Assessing potential risk of heavy metal exposure from consumption of home-produced vegetables by urban populations [PDF]

open access: yes, 2004
We performed a risk assessment of metal exposure to population subgroups living on, and growing food on, urban sites. We modeled uptake of cadmium, copper, nickel, lead, and zinc for a selection of commonly grown allotment and garden vegetables ...
