1 The determining conditions of metaldehyde , paraldehyde, acetaldehyde and nicotinamide were investigated by gas chromatography with correction factors. The method was reliable and rapid.

2 Don't use snail bait that contains metaldehyde, fly bait that contains methomyl, and mole or gopher bait where your dog or cat can get to it.

3 The method to improve the thermal stability of metaldehyde product and the recovery of acetaldehyde from the main by-product paraldehyde were discussed.

4 A projectile with ground-air rocket by the burst of TNT has been designed for dispersing metaldehyde (MA) into the clouds on a large scale.

5 The main composition of this wastewater is acetaldehyde, paraldehyde, metaldehyde, pyridine and some acetaldehyde polymers.
