“…We observed that the shoot As concentration of maize plants concurred with As concentrations in plant shoot reported in earlier studies (Rehman et al, 2016;Rosas-Castor et al, 2014a). For instance, Rosas-Castor et al (2014b) reported that As concentration in shoot of maize plants varied from 0.365-18.5 mg kg -1 DW, where plants were grown in As-spiked sand culture/soils or in Ascontaminated aged soils (soil As ranged: 5-586 mg kg -1 ).…”

“…McBride et al (2015) also found a significant accumulation of As in carrot, lettuce, green bean ( Phaseolus vulgaris L.), and tomato; however, the tested concentrations were much higher than those measured in our studied substrates. Rosas‐Castor et al (2014) observed As accumulation in maize ( Zea mays L.) when grown on a soil with an As concentration comparable with that in our substrates, but their recorded values in the shoot were mainly below our LQ for As (1.24 mg kg −1 , Supplemental Table S1). The elevated total and CaCl 2 –extractible fractions of As were therefore not reflected by As content in plants.…”

The development of a biomonitor in the context of multiple‐element contamination in urban environments was tested by comparing element transfer in edible crops and poplar (Populus trichocarpa Torr. × Populus maximowiczii A. Henry cutlivar ‘Skado’). A multielemental analysis was performed with various common edible crops (cucumber [Cucumis sativus L.], pepper [Capsicum annuum L.], cabbage [Brassica oleracea L.], and lettuce [Lactuca sativa L.]) and the Skado poplar cultivar grown on soils that received sediments dredged from water canals in the 1960s. Sediments were distributed unevenly on the soil, allowing us to sample two types of areas that were either weakly (Area 1) or highly (Area 2) contaminated, mainly by Cd, Pb, and Zn. We registered an accumulation of Cd and Zn in the edible parts of crops, with higher values recorded for leafy vegetables than for fruit vegetables. We did not detect any accumulation of Pb in the plant species studied. We calculated the fresh mass that must be consumed daily to reach tolerable daily intake (TDI) recommendations for each element and found evidence that Cd could be ingested in sufficient amounts to reach the TDI in this context. Poplar and pepper leaves accumulated more Cd and Zn than the edible parts of the study crops grown on both substrates, which suggests that poplar and pepper may be suitable species for biomonitoring element transfer to vegetation in this context. Core Ideas We estimated element transfer from a dredged sediment enriched soil to plants. The suitability of poplar and edible crops as biomonitors was tested. The ‘Skado’ poplar cultivar was confirmed to be a suitable biomonitor candidate The pepper plant is a promising novel candidate in the context of urban gardening.

“…As is classified as a toxic chemical and carcinogenic element, representing a serious environmental problem in Mexico and the world. When there is a greater natural geological presence of As, high levels can be found in groundwater and geothermal water [25,26]. In the present study, 14.28% of the samples exceeded WHO and EPA limits.…”

Background: The purpose of this study was to determine the concentration of inorganic arsenic (As) in the potable water available to the population to be able to estimate the non-carcinogenic risks for underweight children and the carcinogenic risk for adults exposed to As intake who live in the Mezquital municipality, Durango, Mexico. Methods: The As content was quantifed in the water supply sources for human use and its intake was estimated in Mezquital population, southern Durango. With the data obtained, the hazard quotient (HQ) was calculated to determine the non-carcinogenic risk to develop chronic systemic effects in underweight children. The Environmental Protection Agency (EPA) reference health values estimating As exposure risk are from 0.0003 mg/kg/day (non-carcinogenic) to 1.5 mg/kg/day (carcinogenic risk). Results: The analyzed waters presented as concentrations that varied from 0.3 to 10.2 µg/L, with a mean of 7.35 µg/L (CI 95% 6.27–8.38). The exposure dose was 0.4 to 1.36, and the HQ was 1.90 to 6.48 mg/kg/day, the estimated carcinogenic risk from adults varied from 1.28 to 4.37E−4, with values of 3.74–4.37E−4 mg/kg/day in central area. Conclusions: The children are at risk to develop chronic systemic effects due to ingestion of As from water.
