Infobox references. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a polychlorinated dibenzo -p- dioxin (sometimes shortened, though inaccurately, to simply 'dioxin') [3] with the chemical formula C 12 H 4 Cl 4 O 2. Pure TCDD is a colorless solid with no distinguishable odor at room temperature.
Toxic equivalency factor (TEF) expresses the toxicity of dioxins, furans and PCBs in terms of the most toxic form of dioxin, 2,3,7,8-TCDD. [1] The toxicity of the individual congeners may vary by orders of magnitude. With the TEFs, the toxicity of a mixture of dioxins and dioxin-like compounds can be expressed in a single number – the toxic ...
Bunion. A bunion, also known as hallux valgus, is a deformity of the MTP joint connecting the big toe to the foot. [2] The big toe often bends towards the other toes and the joint becomes red and painful. [2] The onset of bunions is typically gradual. [2] Complications may include bursitis or arthritis.
The metatarsal bones or metatarsus (pl.: metatarsi) are a group of five long bones in the midfoot, located between the tarsal bones (which form the heel and the ankle) and the phalanges (toes). Lacking individual names, the metatarsal bones are numbered from the medial side (the side of the great toe): the first, second, third, fourth, and ...
Akin osteotomy. Akin osteotomy is a surgical procedure often used in the treatment of hallux valgus deformity, more commonly known as a bunion. [1] A bunion is a bony bump that forms on the joint at the base of the big toe, often resulting in the toe pointing abnormally toward the second toe. Akin osteotomy is usually performed in conjunction ...
Jeremy Ousey, a musculoskeletal podiatrist in the U.K., explains that bunions develop due to instability in the mid-foot joint where the toes attach.As a result, the big toe can drift away from ...
Additionally, the manufacturing process for 2,4,5-T contaminates this chemical with trace amounts of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). [4] TCDD is a carcinogenic persistent organic pollutant with long-term effects on the environment. With proper temperature control during production of 2,4,5-T, TCDD levels can be held to about .005 ppm.
Common, [4] 8–9% of all fractures [6] A broken toe is a type of bone fracture. [6] Symptoms include pain when the toe is touched near the break point, or compressed along its length (as if gently stubbing the toe). [3] There may be bruising, swelling, stiffness, or displacement of the broken bone ends from their normal position.
