The average age of the child when starting to use a touch-screen gadget was about 11 months and average use was about 36 a few minutes daily. The most common forms of touch screen device usage was watching children's educational shows , using educational applications , pressing buttons on the display screen aimlessly , and playing non-educational games . Sixty % of parents reported educational benefits of the youngster using a touchscreen device. The analysis showed there was no significant difference in testing ratings between kids who used touch-screen gadgets and kids without the same exposure to touch-screen devices. However, results indicated that kids who play noneducational video games have a lower verbal score on developmental checks.PPCPs might prove harmful to the environment due to their unpredictability when mixed with other chemicals. In addition they are highly soluble and some degrade over an extended time period slowly, and as a result some PPCPs are detected in soil and higher up the food chain also. For this reason the US EPA stringently monitors trace concentrations of PPCPs. Liquid chromatography with mass spectrometry delivers the selectivity and sensitivity to detect PPCPs at trace levels required by legislation. The application note explores the high sensitivity of the EVOQ in detecting PPCPS in clean water. Several water samples had been analyzed for a range of PPCP species including plain tap water samples along with bottled and creek drinking water.
