Faucet Aerator III

Aerators should be regularly kept cleaned or replaced. The mesh in the aerator can collect lead debris, and then leach this toxic metal into the water passing through it. Aerators cap the ends of most drinking-water faucets. In some cases, they’re used to conserve water by reducing a faucet’s maximum flow rate; in others their primary function is to concentrate the flow of water so that it delivers more pressure and cleaning power. But these little metal cages also collect debris. Including lead. And unless you’re regularly cleaning out those aerators, you might be developing a toxic mini gravel field through which your drinking water must pass before reaching your glass or coffee pot. Indeed, one lead poisoning case in North Carolina involved a child (see link below): www.dcwater.com/waterquality/faqs.cfm

Torilis Arensis

Torilis arvensis is commonly known as Spreading Hedge Parsley. The plants grow up to 3 feet in height with tiny flowers clustered in small flat-topped umbels. T. arvensis fruit (schizocarp) measure 4-6mm and usually hold 2-4 individual seeds (mericarps). The schizocarp is covered with velco-like appendages which attach to clothing and fur allowing them to hitch a ride to new terrain.  This sample was air dried, mounted onto an aluminum stub and sputter coated with gold.  It was viewed on a Philips XL30 TMP SEM at 20 kV in the EM Lab of the Department of Pathology and Laboratory Medicine at UCDavis. The image was colorized using Adobe PhotoShop Elements 2.0 software. The image shows one of the seeds within the schizocarp and affords a better appreciation for their cunning hitch-hiking techniques. Note the various velco-like appendages. The more "thorny" limbs (tan) are found on the schizocarp while the blunt appendages are part of the mericarp. Pollen (yellow) can be seen on the flower surfaces (pink).
