Resumo: | Vegetable cultivation stands out for intensive use of agricultural inputs due to high nutritional requirements of plants within a short period and their high susceptibility to pests and diseases. This study aimed to identify the main factors responsible for changes in pseudo-total and bioavailable contents of Cd, Cu, Cr, Mn, Ni, Pb, and Zn in soils under intensive vegetable cultivation. Soil samples were collected from 146 sites in Petrópolis (RJ), Brazil, in 2017. The samples were collected at a depth of 0–20 cm in family farm systems during vegetable production period. Pseudo-total contents of toxic elements were determined by the EPA 3050B method. Geochemical fractionation procedure was used based on the BCR method. Pollution indices were also calculated. In general, vegetable producing areas presented low contamination by Cu, Zn, Pb, Mn, and Ni, except for Cd, which showed severe contamination. In areas with the lowest slopes, most of the toxic elements showed increasing contents, reflecting relief influence. Overall, inadequate soil management, intensive application of phosphate, potassium, and organic fertilization, and relief were the most influencing parameters on the enrichment and bioavailability of toxic elements in the soil. |

O cultivo de hortaliças se destaca pelo uso intensivo de insumos agrícolas, devido à exigência nutricional em curto período de tempo e alta susceptibilidade a pragas e doenças. Este estudo teve como objetivo identificar os principais fatores responsáveis pelas alterações nos teores pseudototais e biodisponíveis de Cd, Cu, Cr, Mn, Ni, Pb e Zn nos solos sob cultivo intensivo de hortaliças. Para tal, no ano de 2017, foram coletadas amostras de terra em 146 pontos no município de Petrópolis-RJ. As amostras foram coletadas na profundidade de 0-20 cm, em propriedades familiares com cultivo de hortaliças em pleno período de produção. Para determinação dos teores pseudototais dos elementos tóxicos foi utilizada a metodologia da EPA 3050B. O procedimento de fracionamento geoquímico foi realizado com base no método BCR. Também foram calculados os índices de poluição. Em geral, as áreas produtoras de hortaliças apresentaram baixa contaminação por Cu, Zn, Pb, Mn e Ni, exceto para Cd que apresentou severa contaminação. Nas áreas que apresentam os menores valores de declividade, houve aumento nos teores da maioria dos elementos tóxicos, refletindo a influência do relevo. De maneira geral, o manejo inadequado do solo, a aplicação intensiva de adubação fosfatada, potássica e orgânica, assim como, o revelo, foram as variáveis que mais influenciaram no enriquecimento e biodisponibilidade de elementos tóxicos no solo.
