“…The purpose was to assess human exposure to mercury due to fish consumption and atmospheric contamination from coal-burning power plant and copper smelter. Specifically, the sites Puchuncaví, La Greda and Los Maitenes are located close to copper smelter and coal-burning power plant and these places are strongly impacted by these activities (Parra et al, 2014). In contrary, Quintay is a typical fishing cove, without reported contribution of industrial contamination.…”

In the present study, we assessed mercury exposure of residents of different sites of Valparaiso Region (Chile) due to fish consumption and atmospheric contamination from coal-burning power plant and copper smelter. Total mercury concentration was determined in 199 hair samples and in 14 species of marine fish, purchased in the supermarket or collected in the studied fishing villages-1 in human hair samples and from 0.04 to 3.-1 in fish samples. Importantly, hair mercury concentration was significantly higher in the case of population exposed to mercury exclusively by fish consumption (e.g. Quintay and Zapallar), in comparison to the residents exposed to industrial emissions and fish consumption (e.g. Puchuncavi, Las Ventanas, Quintero). Finally, high mercury concentrations were observed in fish types commonly consumed by the residents of the fishing villages, evidencing human exposure to mercury through fish consumption.

“…Soil pollution by heavy metals is a global environmental issue and a consequence of the escalation of mining and mineral processing, whose spread of metal residues contaminated large areas in Chile (Baize 2009, Parra et al 2014. Metals accumulate in plant organs and tissues causing both physiological and biochemical changes, growth reduction and yield loss, particularly after persistent exposure (Wannaz et al 2006, Mazen et al 2010).…”

Tolerance to metal stress was studied in seedlings of three pine species (Pinus radiata, P. pinaster and P. canariensis) under controlled ex vitro conditions. Mature female cones were randomly collected at two sites in Chile (Llico and Huilquilemu) characterized by contrasting environmental conditions. Oneyear-old pine seedlings were immersed in trays with solutions of CuSO4 (300 mM) or AlCl3 (100 mM), and their survival, growth rate and decay symptoms were recorded for 60 days. Results showed large differences among provenances in seedling tolerance to CuSO4 and AlCl3 in terms of survival and growth. Multivariate analysis revealed a significant association (p <0.0001) between the first canonical function and the following variables: provenance, species, metal stress and growing rate, as well as between the second canonical function and provenance, species, metal stress and symptomatology, indicating a high degree of genotype-environment interaction. Moreover, the activity of POX, SOD and CAT enzymes was determined 60 days after the beginning of the experiment in the Llico provenance seedlings. P. pinaster showed the highest activity level for all the enzymes considered, while P. canariensis and P. radiata had intermediate and lowest values, respectively. Differential gene expression among pine seedlings under metal stress with CuSO4 for two genes (Cu-Zn-superoxide dismutase and RuBisCo) confirmed P. pinaster as the most tolerant species to CuSO4 treatment. Our results are consistent with the hypothesis that abiotic stress in the maternal environment can induce a "transgenerational plasticity" which could affect progeny performances. The influence of different genetic backgrounds on the tolerance to heavy metals in pine seedlings is also discussed.

“…A litologia e os processos de formação do solo estão interligados com os teores de elementos-traços no solo, sendo comum comparar a composição química do solo com o material de origem na avaliação de um solo contaminado (Parra et al, 2014). Para monitorar a contaminação do solo por um elemento, primeiramente, é necessário determinar a concentração do mesmo no solo em seu estado natural (Tarvainen et al, 2013) e, assim, obter os VRQ (Valor de Referência de Qualidade) dos solos (Biondi et al, 2011;Mendoza-Grimon et al, 2014).…”

A determinação do teor natural de elementos-traço é essencial para monitorar a entrada de tais elementos no sistema solo e contribuir na remediação de áreas contaminadas. O objetivo desse trabalho foi determinar o teor natural de Arsênio em solos provenientes de três regiões do estado de Santa Catarina: Planalto Sul, Metropolitana e Litoral Sul. O teor de Arsênio foi obtido após digestão em forno de micro-ondas, seguindo o protocolo da USEPA 3051 A e quantificação em espectrometria de absorção atômica com atomização eletrotérmica. Os resultados foram analisados pelo teste Scott-Knott a 5% de significância. Os atributos do solo que melhor se correlacionaram com os teores de Arsênio foram argila, carbono orgânico, capacidade de troca de cátions e óxidos de alumínio e de ferro. Os teores de Arsênio estão relacionados ao material de origem e ao relevo dos solos das regiões.
