Title A name given to the resource Distribution of cadmium in a cultivated soil in Britanny, France Distribuição de cádmio em solo cultivado na Bretanha, França Creator An entity primarily responsible for making the resource Gisele Mara Hadlich, José Martin Ucha Description An account of the resource Cadmium (Cd) can be potentially toxic to the environment, and its bioavailability is related to the chemical forms it occurs in the soils. The distribution of Cd into the solid phase and its availability was investigated in a cultivated soil in Britanny, France. Cd sequential extraction was performed using a modified Tessier's sequential extraction protocol. Total content of Cd (n = 22 samples) ranged from 0.13 to 0.37 mg kg¹. Long term history of organic and mineral fertilizers application increased Cd concentration in the surface horizon. The fate of Cd was correlated with soil available P2O5 concentration and pH. The regression analysis (linear and non-linear) and Principal Component Analysis revealed the synergistic effect of P2O5 in the retention of Cd in cultivated soils. The following fractions' sequence was observed: bounded to Fe and Al oxides + phosphates > exchangeable > bound to organic matter » residual fraction.O cádmio (Cd) pode ser tóxico no ambiente e sua biodisponibilidade está relacionada às formas químicas em que os metais se encontram no solo. Apresenta-se a distribuição deste metal na fase sólida de um solo cultivado na Bretanha, França, assim como fatores que influenciam sua disponibilidade. Foi realizada a extração sequencial do Cd utilizando o método Tessier, modificado. A concentração total de Cd, avaliada em 22 amostras, variou de 0,13 a 0,37 mg kg¹. O uso contínuo de fertilizantes orgânicos e minerais aumentou a concentração de Cd no horizonte superficial do solo. A distribuição do Cd foi relacionada à concentração de P2O5 disponível e ao pH. Análises de regressão (linear e não linear) e a Análise de Componentes Principais mostraram efeito sinérgico do P2O5 na retenção de Cd nos solos cultivados. O fracionamento apresentou a seguinte sequência: ligado a óxidos de Fe e de Al + fosfatos > trocável > ligado à matéria orgânica » residual.
