“…pXRF was the first analytical technique able to provide relevant information on-site to field geochemists, and in so doing broke the time barrier between sampling, results and decisions, first in environmental investigations, then in mineral exploration (Wiedenbeck, 2013;Lemiere, 2015). Besides its time efficiency, pXRF was also identified as a noninvasive, low environmental footprint technology (West et al, 2013), therefore eligible for "Green analytical chemistry" status (Garrigues and de la Guardia, 2013) and for living material investigations (Sacristán et al, 2016).…”

“…ASTM does not yet provide any standard for field use. Soil contamination applications were recently extended to metal monitoring in crops (Sacristán et al, 2016). Non-destructive applications of pXRF on plants, developed for agronomy purposes (Reidinger et al, 2012), might be used in the future for site diagnosis or verification purposes, alone or combined with infrared .…”

In the last thirty years, portable X-ray fluorescence (pXRF) has grown from prototypes to being a key technique for field geochemical analyses, especially for mining and environmental applications. This technology provides real-time or near real-time decision support for operational field decisions (exploration, mining, site remediation or waste management), provides a cost-saving alternative to classical laboratory analysis programs, and deals efficiently with remote or harsh field conditions. The ability to rapidly collect a large number of samples and replicate analyses facilitates acquisition of higher data density compatible with geostatistics.pXRF can be used profitably for sample screening and selection tasks, dynamic sampling plans based on field observations and measurements, grid mapping of a site and determining relative element abundance. In waste management and remediation, pXRF is used to identify unknown waste composition, and verify waste loads before disposal or treatment.In all applications, having robust QA/QC plans and systematic laboratory controls on selected samples are essential for ensuring reliable measurements. The best overall results are usually achieved through a clever combination of field (pXRF) and lab data, with pXRF providing the bulk of the data at low cost, on larger data sets and potentially with better reliability than lab-based campaigns based on a limited number of samples.

“…A PXRF method was used to measure As and heavy metal content in soil on-site and As content in pine needle samples under laboratory conditions. PXRF is well known as a screening tool for metal and metalloid contents in various environmental samples and a standard protocol regulated by the National Institute for Occupational Safety and Health (NIOSH) and the United States Environmental Protection Agency's Environmental Response Team (USEPA/ERT) [31][32][33][34][35]. Compared with the wet chemical analysis, PXRF has advantages of its non-destructive, rapid measurements and simplified pre-processing procedure.…”

The spectral response to arsenic (As) stress of pine needles (Pinus densiflora Siebold and Zucc.) from an abandoned lead (Pb)–zinc (Zn) mine was investigated based on chemical and spectroscopic analyses. The correlation analysis between the content of As in needle samples and that of soils and spectral parameters of the needle samples were conducted. The results showed very high correlation between As content in pine needles and soils. The major spectral response of pine needles to the As stress were characterized by the increase in the green and red color reflectance, the decrease in the first derivatives at 1648 nm, and the shrink in the red absorption feature. These changes were caused by the pigment content loss and the structural changes of phenolic compounds in the pine needles due to the As content. The linear regression analysis with the stepwise method showed the first derivatives at 668 nm and 1648 nm were the most useful variables in the regression model for As content prediction in pine needles. The As index of pine needles could be used to detect As content in soils associated with As and heavy metals contamination and/or mineralization in coniferous forests.

“…O crescente desenvolvimento agrícola tem resultado em problemas ambientais decorrentes da geração de resíduos contendo elementos tóxicos (JORIS et al, 2012), a contaminação do solo por metais pesados é um problema ambiental bem conhecido, particularmente em regiões agrícolas abandonadas e áreas de minas (SACRISTÁN et al, 2016). Práticas agrícolas inadequadas também podem levar a uma acumulação de Cu no solo (MCLAUGHLIN et al, 2000), decorrentes da utilização de corretivos, fertilizantes, defensivos e fungicidas a base de Cu na camada arável (TURRA et al, 2011), além disso, aplicações repetidas de dejetos de animais podem levar a uma acumulação de Cu (MCGRATH et al, 1982), uma vez que este elemento está incluído na dieta de suínos e aves, como um promotor de crescimento (CHANEY & OLIVER, 1996;RUYTERS et al, 2013) .…”

Resumo -O crescente desenvolvimento agrícola tem resultado em problemas ambientais decorrentes da geração de resíduos contendo elementos tóxicos e algumas práticas agrícolas inadequadas podem desencadear o acumulo de cobre (Cu) no solo. O objetivo do trabalho é avaliar os efeitos da calagem na toxicidade do Cu, sobre a germinação de plantas e na biota do solo. Foram realizados testes ecotoxicológicos de germinação de sementes, as quais foram utilizadas as espécies Avena sativa e Vicia villosa, e teste de fuga com organismos teste da espécie Enchytraeus crypticus, ambos os ensaios foram realizados em Latossolo Vermelho distrófico (LVd) e Neossolo Quartzarênico órtico típico (RQo). Os tratamentos consistiram em doses crescentes de sulfato de cobre (CuSO4), sendo 0; 10, 40, 80, 160 e 320 mg kg -1 , em solo com pH corrigido e não corrigido. A exposição de sementes de A. sativa e V. villosa a doses crescentes de CuSO4 não expressou efeito tóxico na taxa de germinação (P>0,05), em ambos os solos, independente da correção do pH. Foi observado fuga significativa para o LVd, já na primeira dose avaliada e para o RQo também foi observada fuga significativa, no entanto, com variação das doses de acordo com a correção do pH. Deste modo a contaminação de diferentes tipos de solos naturais com CuSO4 não afeta a taxa de germinação das sementes A. sativa e V. villosa, mas para enquitreídeos E. crypticus houve fuga em ambos os solos avaliados (LVd e RQo), indicando que oligoquetas são capazes de detectar e evitar solos contaminados com Cu.Palavras-chave -ecotoxicologia, produção animal, manejo do solo, metal pesado. Abstract -The growing agricultural development has resulted in environmental problems of the generation of waste containing toxic elements and some inadequate agricultural practices can trigger copper (Cu) accumulation in the soil. The aim is to evaluate the effects of liming on copper toxicity, on the germination of plants and soil biota. Ecotoxicological tests of seed germination were performed, which were used species Avena sativa and Vicia villosa, and avoidance test organisms test species Enchytraeus crypticus, both tests were performed in Oxisol (LVd) and Entisol (RQo). The treatments consisted of increasing doses of copper sulfate (CuSO4), and 0; 10, 40, 80, 160 and 320 mg kg -1 in soil pH corrected and uncorrected. The seeds of exposure A. sativa and V. villosa to increasing doses of CuSO4 expressed no toxic effect on the germination rate (P> 0.05) in both soils, regardless of pH correction. Significant avoidance was observed for LVd on the first dose and evaluated for significant avoidance RQo was also observed, however, with a range of doses according to the pH adjustment. Thus contamination of different types of natural soil with CuSO4 does not affect seed germination rate A. sativa and V. villosa, but leakage was enchytraeids E. crypticus evaluated in both soils (LVD and RQo), indicating that earthworms are able to detect and prevent soil contaminated with Cu.Keywords -ecotoxicology, animal production, so...
