Ex situ conservation efforts are the last resort for many critically endangered species, and captive breeding centers are thought to provide a safe environment for producing individuals for eventual re-introduction to the wild. The giant panda (Ailuropoda melanoleuca) is one of the world's most endangered animals and is a widely recognized symbol for conservation. Here, we report that captive pandas in China experience environmental and dietary exposures to high concentrations of persistent organic pollutants (polychlorinated dibenzo-p-dioxins, dibenzofurans, and biphenyls) and heavy metals (arsenic, cadmium, chromium, and lead). In the short term, those animals exhibiting elevated levels of such toxins should be relocated to breeding centers in less contaminated areas. Ensuring the long-term survival of both captive and wild pandas depends in part on reducing atmospheric emissions of toxic pollutants throughout China.

Human exposures to arsenic (As) through different pathways (dietary and non-dietary) are considered to be one of the primary worldwide environmental health risks to humans. This study was conducted to investigate the presence of As in soil and vegetable samples collected from agricultural lands located in selected southern districts of Khyber Pakhtunkhwa (KPK) Province, Pakistan. We examined the concentrations of total arsenic (TAs), organic species of As such as monomethylarsonic acid (MMA) and dimethylarsonic acid (DMA), and inorganic species including arsenite (AsIII) and arsenate (AsV) in both soil and vegetable. The data were used to determine several parameters to evaluate human health risk, including bioconcentration factor (BCF) from soil to plant, average daily intake (ADI), health risk index (HRI), incremental lifetime cancer risk (ILTCR), and hazard quotient (HQ). The total As concentration in soil samples of the five districts ranged from 3.0-3.9 mg kg−1, exhibiting minimal variations from site to site. The mean As concentration in edible portions of vegetable samples ranged from 0.03-1.38 mg kg−1. It was observed that As concentrations in 75% of the vegetable samples exceeded the safe maximum allowable limit (0.1 mg kg−1) set by WHO/FAO. The highest value of ADI for As was measured for M. charantia, while the lowest was for A. chinense. The results of this study revealed minimal health risk (HI <1) associated with consumption of vegetables for the local inhabitants. The ILTCR values for inorganic As indicated a minimal potential cancer risk through ingestion of vegetables. In addition, the HQ values for total As were <1, indicating minimal non-cancer risk.

“…The As uptake by vegetables has been reported in various scientific literature (Warren et al 2003;Das et al 2004;Huq et al 2006;Gusman et al 2013a;Uddh-Soderberg et al 2015). Plants have been found to accumulate the highest As concentration in the roots and the lowest in the edible parts (Lu et al 2010).…”

Background: The uptake of arsenic by vegetables from soil irrigated with arsenic enriched groundwater poses a major health hazard. The edible portion of these vegetables transfer arsenic to the human beings. The uptake of arsenic was studied in bean (Phaseolus vulgaris L.) and lettuce (Lactuca sativa L.) in a controlled greenhouse pot culture with calcareous sandy soil as substrate. The plants were irrigated with water containing sodium arsenate at concentrations 0.1, 0.25 and 0.5 mg L − 1. The total arsenic concentration of the different plants parts was determined by ICP-MS, following microwave-assisted acid digestion. The change in plant biomass production and essential macroelements (Mg, P, K) and microelements concentration (Fe, Mn, Cu, Zn) was also studied. Results: The As concentration in the bean was in the order: root>stem>leaf>bean fruit and in lettuce: root>leaves. At the highest dose (0.5 mg L − 1) the As concentration in the bean fruit and lettuce leaves was 22.1 μg kg − 1 and 1207.5 μg kg − 1 DW, respectively. Increasing As concentration in the irrigation water resulted in decreased edible biomass production in bean, while in lettuce the edible biomass production increased. Neither plant exhibited any visible toxicity symptoms. No significant change was observed in the macro and microelements concentration. The total and the water-soluble arsenic in soil amounted to 3.5 mg kg − 1 and 0.023 mg kg − 1 , respectively. The transfer factor was found to increase with increase in the As treatment applied. The transfer factor range for bean from root to fruit was 0.003-0.005, and for lettuce from root to leaves was 0.14-0.24. Conclusion: Considering the FAO-WHO recommended maximum tolerable daily intake (MTDI) limit of 2.1 μg kg − 1 body weight, and the biomass production, both plants should not be cultivated at As treatment level higher than 0.1 mg L − 1. Keywords: Arsenic/irrigation water/ uptake/ transfer factor/calcareous sandy soil/vegetables contamination of the groundwater and soil is a major environmental toxicity issue, especially in Southeast Asia and in countries like China,
