“…In case of all samples collected from the quarries, the maximum admitted value established by legislation was exceeded. A review analysis carried out by de Vasconcelos Neto et al [16] on the Pb contamination in food, generally showed lower concentrations than in the present study. However, for zeolites samples from Serbia, Tomasevic-Canovic [9] reported Pb concentrations in the range of 29-38 mg kg −1 , which is higher than in our case.…”

“…Cd is associated with negative health effects on renal, skeletal, pulmonary, reproductive, and cardiovascular systems, which are classified as group I carcinogens to humans [13]. Pb may also causes serious damages for human health and may cause even death [14][15][16]. The presence of toxic metals in the raw ingredients used to produce dietary supplements is undesirable.…”

An analytical method based on microwave-assisted acid digestion and atomic absorption spectrometry with graphite furnace as atomization source was developed and validated for determining trace elements (Cd and Pb) in zeolites used as dietary supplements, for their characterization and safety evaluation. The method was checked for the main performance parameters according to the legislation requirements in the field of dietary supplements. In all cases, the obtained performance parameters were satisfactory. The selectivity study showed no significant non-spectral matrix effect. The linearity study was conducted for the calibration curves in the range of 0–10 ng mL−1 for Cd and 0–30 ng mL−1 for Pb. The obtained limits of detection (LoDs) and the limits of quantification (LoQs) were sufficiently low in order to allow Pb and Cd determination in dietary supplements. For the internal quality control, certified reference materials were analysed and good recoveries were obtained. The precision study was performed in terms of repeatability and reproducibility, considering the requirements imposed by the Commission Decision (2007/333/EC) and the method fulfilled these performance parameters. Expanded measurement uncertainties were estimated to 11% for Cd and 10% for Pb. Cd and Pb content were measured in real zeolite samples and, using these data, a safety evaluation was carried out.

“…On the other hand, Pb contents in this pulp are near those of other edible fruit such as apple (2.35 mg/100 g), mango (6.72 mg/100 g) [ 44 ] and tomato (5.41–11.73 mg/100 g) [ 45 ]. The risk of consuming food with a high amount of Pb is correlated with intelligence reduction, bone joint weakness, accelerated bone maturation, increased blood pressure, spontaneous abortion, renal dysfunction, allergic diseases [ 46 ], respiratory and cardiovascular diseases [ 47 ].…”

This study aimed to quantify the extent of heavy metal, non-metal and metalloid levels in the Campomanesia adamantium pulp obtained from an area crossed by road experiencing high large vehicle traffic and intensive agriculture modern farming, to monitor the health risks associated with pulp consumption by humans. For this purpose, in three spots located within this area, ripe fruits were collected on the roadside, bush and farm-margin. Pulp samples were digested by microwave-assisted equipment, and chemical elements were quantified by ICP OES. The concentrations of K, Pb, Se, Fe, Mo, Zn, Co, Ni and Mn in the pulp collected in roadside/bush points showed statistical differences (p < 0.05). The heavy metals and metalloid concentrations that exceeded FAO/WHO standards were ordered Pb > As > Mo > Co > Ni > Mn > Cr. Therefore, among these metalloid and heavy metals, As, Pb and Cr were found to be higher in farm-margin > roadside > bush (1.5 × 10−3, 1.1 × 10−3 and 6.2 × 10−4), respectively. Therefore, As is the most important metalloid with higher levels in farm-margin, roadside and bush (1.5 × 10−3, 1.0 × 10−3 and 6.0 × 10−4 > 10−6–10−4 and 3.33, 2.30 and 1.34 > 1), respectively, to total cancer risk and hazard quotient, if 10 g daily of pulp are consumed.

“…Si se comparan los resultados de este estudio con otras investigaciones llevadas a cabo en América Latina, la variabilidad sigue siendo significativa, incluso dentro del mismo país. En el caso de Brasil, la contaminación por Pb excedió los límites establecidos tanto en la leche cruda como en los derivados de la leche (Silva y col., 2010;Oliveira y col., 2017;Vasconcelos y col., 2019;Gomes y col., 2013). En Puebla, México, el análisis de muestras de leche cruda reveló la presencia de Pb a una abundancia media de 0,03 mg/kg, y a una abundancia media de 0,12 mg/kg.…”

La evaluación de metales pesados en leche puede considerarse como indicador de contaminación ambiental de un lugar, por lo que el objetivo de la investigación fue determinar la presencia de Plomo, Mercurio y Arsénico en leche cruda de Machachi, Provincia de Pichincha-Ecuador. Se recolectaron 58 muestras provenientes de 29 fincas lecheras con sistema de pastoreo extensivo y ubicadas hasta máximo un kilómetro a la redonda del Municipio de Machachi, donde existe actividad industrial y está cerca de la Panamericana Sur. Las muestras fueron analizadas mediante la técnica de espectrofotometría de absorción atómica por generador de hidruros (Mercurio y Arsénico) y con horno de grafito (Plomo). Todas las muestras analizadas mostraron niveles de Plomo, con una media de 0.208 mg/kg (rango entre 0.0016 a 0.719 mg/kg), de las cuales el 98.28% (57/58) contienen niveles superiores a los máximos permitidos por la NTE INEN 9 de 0.02 mg/kg. También se detectó Mercurio en cuatro muestras (media de 0.00009 mg/kg, rango entre 0.00 a 0.002 mg/kg) y Arsénico en dos muestras (media de 0.00003 mg/kg, rango 0.00 a 0.001 mg/kg), sin embargo, las mismas estuvieron por debajo del límite permitido por el Codex Alimentarius (0.01 mg/kg) en alimentos en general. Con los resultados obtenidos, se concluye que podría existir un área contaminada con Pb, por lo que se debe realizar un monitoreo continuo en leche, y ampliar la investigación a las posibles fuentes de contaminación, como agua de bebida, agua de riego, forrajes y alimentos que reciben las vacas lecheras de la zona.
