[RC] Horse Coughing - Wendy Harris - Ridecamp GuestPlease Reply to: Karen Lynd jklynd@xxxxxxxxxxxxx or ridecamp@xxxxxxxxxxxxx ========================================== Hi Wendy, I am reading the archives too, so I can't see your e-mail address. I would not rule out your horse's symptoms being caused by the wolmonized lumber the horse is chewing on. A quick Google search for wolmonized lumber revealed the following information: Wolmanized wood is lumber pressure-treated with ARCH Wood Production, Inc.'s Wolman CCA chemicals preservative, a diluted solution of Chromated Copper Arsenate. CCA, or Chromated Copper Arsenate, is a chemical wood preservative and pesticide formulation that is regulated by the Environmental Protection Agency. CCA consists of three prinicipal compounds ? arsenic in the form of arsenic pentoxide, chromium, in the form of both hexavalent chromium and trivalent chromium, and copper in the form of copper oxide(2). Two of these chemical components (arsenic and hexavalent chromium) have a notorious reputation as toxins, carcinogens and teratogens, as the following article details: http://www.bancca.org/Health_Hazards/CCA_Health_Hazards.htm#Sect_2_0 The referenced article notes that the two most commonly-reported neurological effects of severe or chronic arsenic exposure are "pins and needles" feeling in the hands and feet, and partial paralysis of the limbs.... Other noted neurological side effects include hearing loss, memory loss, headaches, depression, anxiety attacks, and muscle and joint pain. There are also respiratory symptoms: Continuous arsenic exposure can cause irritation and damage to the mucous membranes in nasal passages and airways, including pharyngitis and rhinitis, and can also aggravate symptoms of asthma.... You may want to research wolmonized lumber further and give the information to your veterinarian. I hope this helps.
