Grow pests favorite plants to lure them away from your garden crops. Plant these trap crops around your garden or between the rows. When a trap crop becomes infested, pull it and destroy the pests. For pests that disperse quickly when disturbed, cover the trap plants with a sheet or bag before you pull them. This control method works best for pests that produce only a few generations each summer or for crops that need protection for a short, critical period in the season. A drawback is that you have to sacrifice harvest from the trap crop and garden space to grow it.

Plutonium (Pu) is an artificial element of atomic number 94 that has its main radioactive isotopes at 2 °Pu and Pu. The major sources of this element arise from the manufacture and detonation of nuclear weapons and from nuclear reactors. The fallout from detonations and discharges of nuclear waste are the major sources of plutonium contamination of the environment, where it is trapped in soils and plant or animal life. Since the contamination levels are generally very low, a sensitive technique is needed to estimate its concentration. However, not only the total amount can be estimated. Measurement of the isotope ratio provides information about its likely... 

Del y for Dec y. Nuclear power plants generate radioactive xenon and krypton as products of the fission reactions. Although these products ate trapped inside the fuel elements, portions can leak out into the coolant (through fuel cladding defects) and can be released to the atmosphere with other gases through an air ejector at the main condenser. 

If the spent fuel is processed in a nuclear fuel reprocessing plant, the radioactive iodine species (elemental iodine and methyl iodide) trapped in the spent fuel elements ate ultimately released into dissolver off gases. The radioactive iodine may then be captured by chemisorption on molecular sieve 2eohtes containing silver (89). 

The most overlooked hazard and contaminant is water (99). Water reacts with isocyanates at room temperature to yield both ureas and large quantities of carbon dioxide. The presence of water or moisture can produce a sufficient amount of CO2 to overpressurize and mpture containers. As Httle as 30 mL of water can result in 40 L of carbon dioxide which could result in pressures of up to 300 kPa (40 psi). For these reasons, the use of dry nitrogen atmospheres is recommended during handling. If a plant air system must be used, purification equipment, such as oil traps and drying beds, should be installed between the source and the isocyanate vessel. 

Other Chromates and Dichromates. The wet operations employed in the modem manufacture of the chromates and dichromates are completely enclosed and all stacks and vents equipped with scmbbers and entrainment traps to prevent contamination of the plant and its environment. The continuous process equipment that is used gready faciHtates this task. The trapped material is recycled. 

Condensa.te Return Systems. Ia a process plant, steam traps are used to drain and return condensate. Given proper appHcation and continuous maintenance, these can operate with minimal steam leakage. Correct iastaHation is also important (12). 

In normal plant operation at least two adsorption purifiers are employed—one in service while the other being desorbed of its impurities. In some cases there is an advantage in using an additional purifier by placing this unit in series with the adsorption unit to provide a backup if impurities are not trapped by the first unit. The cooling of the purifier must be effected with some of the purified gas to avoid adsorption during this period. 

Traps for small (test stand used), medium (in-plant testing), and large (in-plant testing) condensate loads were tested against a perfect rating of 30. The results are in Tables 1, 2, and. 3. 

Before the exchanger left the plant, the free tubes v. ere cleaned with high-pressure water jets. The plugged tubes were opened up by drilling >s-in. holes through the plugs to relieve any trapped pressure. But these holes were not big enough to allow the tubes to be cleaned. 

Many accidents, particularly on batch plants, have been due to runaway reactions, that is, reactions that get out of control. The reaction becomes so rapid that the cooling system cannot prevent a rapid rise in temperature, and/or the relief valve or rupture disc cannot prevent a rapid rise in pressure, and the reactor ruptures. Examples are described in the chapter on human error (Sections 3.2.1 e and 3.2.8), although the incidents were really due to poor design, which left traps into which someone ultimately fell.
