• JAMA -- Abstract: Lead, Mercury, and Arsenic in US- and Indian-Manufac tured Ayurvedic Medicines Sold via the Internet, August 27, 2008, Saper et al. 300 (8): 915: These heavy metals are highly toxic, especially if taken in either high doses or chronically over a long period of time. Herbal medicine may sound healthful, but it may also be slowly poisoning you; quality is not guaranteed.
• Lead, Mercury, and Arsenic in Ayurvedic Medicines: One-fifth of both US-manufacture d and Indian-manufac tured Ayurvedic medicines purchased via the Internet contain detectable lead, mercury, or arsenic.

• Phytotoxicity of salt and plant salt uptake: Modeling ecohydrologica l ecohydrologica l feedback mechanisms: A new model of phytotoxicity of salt and plant salt uptake is presented and is coupled to an existing three-dimensio nal groundwater simulation model. The implementation of phytotoxicity and salt uptake relationships is based on experimental findings from willow trees grown in hydroponic solution. The data confirm an s-shaped phytotoxicity relationship as found in previous studies. Uptake data were explained assuming steady state salt concentration in plant roots, passive salt transport into the roots, and active enzymatic removal of salt from plant roots. On the one hand, transpiration strongly depends on groundwater salinity (phytotoxicity ); on the other hand, transpiration significantly changes the groundwater salinity (uptake). This feedback loop generates interesting dynamic phenomena in hydrological systems that are dominated by transpiration and are influenced by significant salinity gradients. (...)
