Abstract

OBJECTIVE: To evaluate traditional acidic curing as a preventive method for reducing lead content of glazed ceramic ware. MATERIAL AND METHODS: In 27 ceramic ware pieces from four states in Mexico, the level of residual lead was determined through atomic absorption spectrophotometry after four washings with acetic acid 3%. RESULTS: The lead content of the vinegar washing diminished proportionally with the number of washings, although it remained highly above the permissible levels of this metal (2.5-7.0 p.p.m.). CONCLUSIONS: Traditional acidic curing of glazed ceramic ware is not a useful preventive measure for reducing lead exposure.

A new type of chopsticks for patients with impaired hand function.

OBJECTIVES: To present a method for adapting chopsticks to persons with hand impairments and to compare the efficiency of the adapted chopsticks with spoons among adults with cervical spinal cord injury (SCI). DESIGN: Equipment development and pilot evaluation. SETTING: Rehabilitation center. PARTICIPANTS: Two adults with complete C8-level SCI and 9 adults with incomplete SCI from the C6 to C8 level. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Instructions for adapting chopsticks and the time to pick up and manipulate 4 types of food (noodle strips, cubed carrots, unshelled peanuts, tofu cube) by using adapted chopsticks as compared with spoons. RESULTS: The mean time for manipulating tofu was comparable between the adapted chopsticks and spoon, but the adapted chopsticks were sufficiently faster than spoons for noodle strips, carrots, and unshelled peanuts. CONCLUSIONS: Adapted chopsticks convert gross grasp into 2-point pinch. They are inexpensive, easily constructed, and may benefit patients with lower cervical SCI and residual gross grasp.

Migration of formaldehyde and melamine monomers from kitchen- and tableware made of melamine plastic.

Migration of one or both formaldehyde and/or melamine monomers was found in seven of ten tested melamine samples bought on the Danish market. The samples were a bowl, a jug, a mug, a ladle, and different cups and plates. No violation of the European Union-specific migration limits for melamine (30 mg kg-1) and formaldehyde (15 mg kg-1) was found after three successive exposures to the food stimulant 3% acetic acid after 2 h at 70 degrees Celsius. To investigate the effects of long-term use, migration tests were performed with two types of cups from a day nursery. Furthermore, medium-term use was studied by ten successive exposures of a plate to 3% acetic acid for 30 min at 95 degrees Celsius. The results indicate that continuous migration of formaldehyde and melamine takes place during the lifetime of these articles. The molar ratio of released formaldehyde to melamine was seen to decrease from 12 to about 5. This indicates that, first, the migration of residual monomers is most important, but in the long-term, breakdown of the polymer dominates. Two CEN methods were used to determine the concentration of monomers: a spectrophotometric method for formaldehyde and a UV-HPLC method for melamine.
