During visits to their respective homes, all four children were observed playing and digging in the soil in unvegetated areas, and at one point child H1A, who reportedly sucked his thumb, was observed to be eating soil.
In response to DOH sample results and counseling, the parents of H1A and H1B began cleaning the interior of the home with phosphate detergents and restricting the children's access to the yard.
The parents of H1A and H1B reported that this remedial work was completed in March 1992, at a cost of approximately $400.
Canon's new XL H1S and XL H1A camcorders, which will be on display at the 2008 NAB Show (Booth #SU3020), feature an updated Canon 20x HD Video Lens with three independent manual adjustment rings (focus, zoom and iris), as well as enhanced manual focus and zoom control.
Both the new XL H1S and XL H1A deliver superior HD image quality with their Genuine Canon XL interchangeable lens system, three 1/3 inch, 1.
The new XL H1S and XL H1A HD camcorders continue to meet the needs of producers, event videographers, and digital cinematographers with superior Canon optical and imaging technology, and with the most cost-effective medium for high-quality HD video capture and storage, which is HDV tape," noted Yuichi Ishizuka, senior vice president and general manager, Consumer Imaging Group, Canon U.
Leveraging Canon's expertise as a worldwide leader in optics, the XL H1S and XL H1A feature a redesigned Genuine Canon 20x HD Video Zoom Lens equipped with Canon's XL lens mount.
Both the XL H1S and XL H1A HD camcorders provide Total Image Control for customizing image and color settings, with a total of 23 custom presets available for image-quality adjustment, with the range of image color presets extended from +/-9 to +/-50 steps for fine-tuning the picture (an important feature for achieving the visual subtleties favored by cinematographers).
These include 22 items and 40 sub-items for selection of status information that can be shown in the XL H1S and XL H1A HD camcorders' 2.
User-requested refinements in the XL H1S and XL H1A audio capabilities include: two-channel audio performance; two built-in XLR terminals with separate audio-input sensitivity settings; the ability to simultaneously record sound from an external microphone and the supplied internal microphone; line output level switching; an audio (manual) limiter; a new metal headphone jack for reliable connectivity.
